    The Point-to-Point Interface (PPS)

    The Point-to-Point Interface (PPS deriving from the German term "Punkt-zu-Punkt Schnittstelle") is compatible to the other systems on a physical layer, but not in the way message telegrams are being exchanged. While BSB and LPB talk to each other by sending telegrams and acknowledging their receipt respectively, PPS is dominated by the heating unit. The heating unit constantly sends its data to the room unit and tells the room unit when and what kind of information it should send. So it may take up to a few minutes until a value that is set in BSB-LAN is actually requested by the heating system and shown there.
    It is also a very timing sensitive protocol, therefore long other tasks that BSB-LAN is told to do will lead to a temporary interruption and possible error message on the heating system. However, after a short while, this should be clearing by itself when the two components "talk" to each other again.

    Other than BSB and LPB, changes made in BSB-LAN do not take immediate effect. Changing values, for example like the room temperature comfort setpoint, will be stored internally in BSB-LAN first to be sent out to the heating system once it tells the room unit (i.e. BSB-LAN) to do so. This may take up to a minute or so, so one should not be confused that settings do not show up on the heater immediately, as is the case with BSB and LPB.

    -

    With PPS, BSB-LAN can run in two modes: passive and as a room unit. In passive mode, BSB-LAN can just listen to the data exchanged between the room unit and the heating device. It is not possible to send one's own data, for the simple fact that it would be overwritten in no time by the same type of data coming from the room unit.

It is not possible to send one's own data, for the simple fact that it would be overwritten in no time by the same type of data coming from the room unit.
    In order to send parameter data to the heating system, BSB-LAN mus run in "room unit" mode, and this means that any room unit will have to be removed from the heating system. In this case, it is especially important to regularly send a room temperature value to BSB-LAN which in turn will send this value to the heating device. Only if the heater runs solely on outside temperature then this value can be ignored.
    BSB-LAN stores some values in its non-volatile EEPROM, but some values need to be set anew after a reboot, such as the room temperature setpoint. This is to prevent to store a parameter value that has become invalid but is still sent as it is stored in the EEPROM.

    Room units commonly used with heating systems that support PPS are the QAA50 and the QAA70.

    What is BSB-LAN?

    BSB-LAN is a software/hardware solution for accessing the “Boiler-System-Bus” (BSB), the “Local-Process-Bus (LPB)” and the “Punkt-zu-Punkt-Schnittstelle” (PPS). The BSB-LAN hardware is available for various ESP32-based microcontrollers (ESP32 NodeMCU, Olimex EVB, Olimex POE-ISO) as well as for an Arduino Due with Ethernet shield. It allows accessing the heating systems from Atlantic, Brötje, Elco and many other manufacturers via LAN/WLAN, provided that they use one of the Siemens controllers listed below.
    -BSB-LAN makes it possible to monitor and control the heating and log any given values. This project supports almost all parameters available on the heating systems and can be a more comprehensive and cost-effective alternative to the OZW 672, OCI 700 or Remocon Net B.

    Optional integration into existing smart home systems such as Home Assistant, ioBroker, openHAB, Node-RED, Homebridge, Jeedom, SmartHomeNG, Volkszähler, FHEM, HomeMatic, Loxone, IP-Symcon or EDOMI is possible via MQTT, JSON or HTTP access. The adapter can also be used as a standalone logger without LAN or Internet connection when using a microSD card.
    Temperature and humidity sensors can also be connected and their data can also be logged and analyzed. The option of integrating your own code into the BSB-LAN software also offers a wide range of expansion options.

Optional integration into existing smart home systems such as Home Assistant , ioBroker , openHAB , Node-RED , Homebridge , Jeedom , SmartHomeNG , Volksz\u00e4hler , FHEM , HomeMatic , Loxone, IP-Symcon or EDOMI is possible via MQTT , JSON or HTTP access . The adapter can also be used as a standalone logger without LAN or Internet connection when using a microSD card. Temperature and humidity sensors can also be connected and their data can also be logged and analyzed. The option of integrating your own code into the BSB-LAN software also offers a wide range of expansion options.","title":"What is BSB-LAN?"},{"location":"index.html#where-and-how-do-i-begin","text":"You are an experienced user?

While a bus speed of a mere 4800 bits per second might sound anachronistic these days, it still provides for a stable and robust transmission protocol that is even today perfectly sufficient when it comes to transmitting short messages of a few dozen bytes over lines sometimes as long as one kilometer. The bus topology also allows you to connect BSB-LAN at any point: At the room unit, at the heating system or anywhere where the bus lines are available. You can even add the two wires for BSB-LAN in an already \"occupied\" slot, and it won't harm the other device (proper installation assumed). On top of the same physical layer, three bus systems, BSB, LPB and PPS, cater for different tasks, and while BSB and LPB should always be preferred if available, PPS nevertheless provides a set of parameters that is usually quite enough for the average user. BSB-LAN runs on any of these busses and swapping between them is just changing a few settings away. The Boiler System Bus (BSB) BSB is the most common bus system in Siemens controllers for the last 10-15 years. It is the successor of the PPS system with which it shares the same physical parameters, but is much more versatile: Instead of just a few dozen parameters, it can access hundreds of parameters and group them into various categories for easier navigation. It is a transaction-based protocol where most messages are being sent from one device to another and the recipient returning some kind of feedback, for example whether the task could be completed or whether it contained invalid data. While BSB is capable of addressing multiple devices on the bus, it is not used in systems with more than one heating device. The heating device always has the ID 0 , the display unit on the heating system has the ID 10 (or 0x0A in hexadecimal) and the standard room unit has the ID 6 . BSB-LAN has the ID 66 or 0x42 in hexadecimal. Room units that \"speak\" BSB are, for example, the QAA55 and the QAA75. The Local Process Bus (LPB) LPB was introduced more or less around the same time as PPS which it complemented in terms of communication with other heating devices: While PPS was used to communicate with the room unit, LPB was used to send commands from one main heating device to one or more auxilliary heating devices, for example in a cascade setup. At that time, most of the information transmitted via LPB was related to the internals of the heating system (such as sensor data or internal setpoint temperatures), whereas the parameters relevant for the user (such as comfort temperature setpoint etc.) were only available via PPS. Nowadays, heating devices that offer both LPB and BSB have the same kind of parameter data available on both bus systems. LPB uses a specific addressing scheme with segments and devices. Each segment from 0 to 15 can contain up to 15 devices (from 1 to 15). When writing these addresses, segment and device are separated by a colon: 00:01 or 04:03 . To convert the segment-based address into the destination ID required for BSB-LAN, the formula is as this: SEGMENT multiplied by 16 plus DEVICE minus one. Example: Device 3 in segment 4 equals to 4 * 16 + 3 - 1 = 66. The main heating unit is by definition 00:01 , so this equals to a destination ID 0. To learn more about the LPB system and how it should be deployed, you may refer to these two documents from the end of the 1990s, one covers the basic system data that covers the conceptualization of an LPB network, and the other one deals with the basic engineering data and provides details about cable lengths and diameters etc. Except for some Weishaut heaters, room units are not connected to the heating system via LPB. Newer models use BSB for this task while older models use either PPS or in some cases also OpenTherm. The Point-to-Point Interface (PPS) The Point-to-Point Interface (PPS deriving from the German term \"Punkt-zu-Punkt Schnittstelle\") is compatible to the other systems on a physical layer, but not in the way message telegrams are being exchanged. While BSB and LPB talk to each other by sending telegrams and acknowledging their receipt respectively, PPS is dominated by the heating unit. The heating unit constantly sends its data to the room unit and tells the room unit when and what kind of information it should send. So it may take up to a few minutes until a value that is set in BSB-LAN is actually requested by the heating system and shown there. It is also a very timing sensitive protocol, therefore long other tasks that BSB-LAN is told to do will lead to a temporary interruption and possible error message on the heating system. However, after a short while, this should be clearing by itself when the two components \"talk\" to each other again. Other than BSB and LPB, changes made in BSB-LAN do not take immediate effect. Changing values, for example like the room temperature comfort setpoint, will be stored internally in BSB-LAN first to be sent out to the heating system once it tells the room unit (i.e. BSB-LAN) to do so. This may take up to a minute or so, so one should not be confused that settings do not show up on the heater immediately, as is the case with BSB and LPB. With PPS, BSB-LAN can run in two modes: passive and as a room unit. In passive mode, BSB-LAN can just listen to the data exchanged between the room unit and the heating device. It is not possible to send one's own data, for the simple fact that it would be overwritten in no time by the same type of data coming from the room unit. In order to send parameter data to the heating system, BSB-LAN mus run in \"room unit\" mode, and this means that any room unit will have to be removed from the heating system. In this case, it is especially important to regularly send a room temperature value to BSB-LAN which in turn will send this value to the heating device. Only if the heater runs solely on outside temperature then this value can be ignored. BSB-LAN stores some values in its non-volatile EEPROM, but some values need to be set anew after a reboot, such as the room temperature setpoint. This is to prevent to store a parameter value that has become invalid but is still sent as it is stored in the EEPROM.

Any further changes can be done also in the web-interface. It may, however, be useful to do the configuration (also) in the configuration file in case one needs to change the microcontroller. Almost all settings exist also in the web-interface and vice versa. On an ESP32-based microcontroller, BSB-LAN will set up its own wireless access point named BSB-LAN if it cannot connect to any network. So even without any further configuration, you can connect to this access point with the password BSB-LPB-PPS-LAN and access BSB-LAN via the IP address http://192.168.4.1 and proceed with the configuration via this way. Keep in mind that if you have set a passkey or HTTP username and password, these are still required if these details are stored in EEPROM or BSB_LAN_config.h . Configuration through `BSB_LAN_config.h`` The configuration file consists of variables that are used in other parts of BSB-LAN. It is therefore important to only change the contents of the variables (i.e. the settings) and not the type of the variables. So if there is for example the setting byte ip_addr[4] = {192,168,178,88}; you must not alter the byte ip_addr[4] = part, only the contents, in this case the comma-separated IP address. Configuration through the web-interface Configuring BSB-LAN through the web-interface is pretty straightforward, as you don't have to deal with variable names but clear descriptions.

Any further changes can be done also in the web-interface. It may, however, be useful to do the configuration (also) in the configuration file in case one needs to change the microcontroller. Almost all settings exist also in the web-interface and vice versa. On an ESP32-based microcontroller, BSB-LAN will set up its own wireless access point named BSB-LAN if it cannot connect to any network. So even without any further configuration, you can connect to this access point with the password BSB-LPB-PPS-LAN and access BSB-LAN via the IP address http://192.168.4.1 and proceed with the configuration via this way.

As a prerequisite, a MQTT broker (such as mosquitto is needed, either running locally or via making use of a public service. Some home automation systems such as Home Assistant offer the installation of mosquitto as part of their software. In BSB-LAN, you need to make or enable at least the following configurations: Set Logging mode (additionally) to Send to MQTT Broker . Set Log Interval to the time (in seconds) you want the log parameters to be published. Select up to 20 Log Parameters you want to be sent to your home automation system. Set MQTT Usage to plain text Set MQTT Broker Server to the hostname of your MQTT broker (such as the mosquitto server) If your home automation system supports MQTT auto-discovery (as is the case with Home Assistant), you can call URL command /M1 and BSB-LAN will send auto-discovery messages for all available parameters to the MQTT broker and thus to the home automation system. You may have to clean up afterwards or send a removal message for all these parameters using URL command /M0 . Every time a query is made in BSB-LAN or a parameter changes its value through the room unit, the new value will be sent to the MQTT broker, so even changes made outside of BSB-LAN should be updated into the home automation system, which is why the MQTT approach is the recommended way to connect to a home automation system. Examples for querying or setting parameters via MQTT would look like this (using mosquitto): Query the outside temperature (parameter 8700): mosquitto_pub -h my.mosquitto-broker.local -u USER -P PASSWORD -m \"8700\" -t BSB-LAN -d Set the comfort temperature setpoint (parameter 710) to 20 degrees: mosquitto_pub -h my.mosquitto-broker.local -u USER -P PASSWORD -m \"S700=20\" -t BSB-LAN -d Exchanging data via JSON BSB-LAN allows to query and set parameters via JSON structures and also provides numerous information about the parameters and category structures this way. The JSON API is accessd via URL commands and the openapi.yaml file provided in this repository can be used with Swagger to explore its possibilities and functionalitites.

Navigate to the BSB_LAN folder and rename the following files: BSB_LAN_custom_defs.h.default to BSB_LAN_custom_defs.h BSB_LAN_config.h.default to BSB_LAN_config.h . Download and install the Arduino IDE for your system. Connect your microcontroller (ESP32 or Arduino Due) to your computer and start the Arduino IDE. Go to Tools/Board/Board Manager and make sure that the framework for your board is installed (\"esp32 by Espressif Systems\" for ESP32 microcontroller, \"Arduino SAM Boards (32-bits ARM Cortex-M3) by Arduino\" for Arduino Due microcontroller) Again, go to Tools/Board and select your microcontroller: ESP32 Dev Module for the Joy-It ESP32 NodeMCU. Olimex ESP32-EVB for the ESP32-based Olimex EVB . Olimex ESP32-POE-ISO for the ESP32-based Olimex POE ISO Arduino Due (Programming Port) for the Arduino Due. Do not use the Native USB Port here ! Again, go to Tools/Board and select the proper upload speed (460800 for ESP32, 115200 for Arduino Due). For ESP32-based microcontrollers, again, go to Tools/Board and select \"Minimal SPIFFS (Large APPS with OTA)\" for partition scheme ( do not confuse this with the similar \"Minimal\" partition scheme which is different and not working in our case). If you don't set the correct parition scheme, the firmware will not fit into the ESP32! Go to File/Open and navigate to the BSB_LAN folder and double-click on BSB_LAN.ino . The project will open. You may now proceed to configure BSB-LAN. When you are done configuring, go to Sketch/Upload and upload the BSB-LAN software to the microcontroller. Subsequent updates on ESP32-based microcontrollers \"over the air\" (OTA) If you are running BSB-LAN on an ESP32-based microcontroller and have enabled Over-the-Air Updates in the settings , you can perform future updates of BSB-LAN using your browser. To do that, instead of using Sketch/Upload , you need to select Sketch/Export Compiled Binary . This will create a build folder in your BSB-LAN folder in which you will find among others the file BSB_LAN.ino.bin . Now open http://bsb-lan.local:8080 and select and upload that file. Do not interrupt the upload process. You may try to access BSB-LAN from a different browser window to see if the process is completed. Please take note that this only applies to ESP32-based microcontrollers. Arduinos do not support this functionality. Assembling the BSB-LAN adapter You can either get a fully assembled adapter from Frederik (bsb(\u00e4t)code-it.de) or build one on your own (see the folder schematics for the schematics). Once you have the BSB-LAN adapter ready, you just need to plug it into the microcontroller. If you are using an Olimex microcontroller, double-check that the adapter really sits in the center of the connector, because it still fits even if it is moved by one pin row to the left or right. Connecting BSB-LAN to the heating system Once the microcontroller and the BSB-LAN adapter are ready, perform the following steps to connect BSB-LAN to the heating system: Unplug the microcontroller from your computer and turn off your heating system. Locate the BSB/LPB/PPS connectors. You may have to open your heating system for that. Have a look at the list of supported heating systems to get an idea where the pins are located. Do all this at your own risk! Especially take care to prevent electrostatic discharge (ESD) which can destroy both BSB-LAN and the heating controller! Now plug the BSB-LAN adapter onto the microcontroller and connect the + screw connector to the CL+ (BSB), DB (LPB) or A6 (PPS, different connector names are possible) connector, and the - screw connector to the CL- (BSB), MB (LPB) or M (PPS) connector. If there is no empty connector, there is no problem adding the wires for BSB-LAN to an already \"used\" connector, provided the wires are inserted carefully. Now you need to power on the microcontroller. Take note that the heating system does not power the microcontroller, even if the BSB-LAN adapter's LED turns on when you connect it to the heating system. You need to supply power to the microcontroller via its USB port (or via PoE on the Olimex POE-ISO). Make sure to use a stable power supply with at least 2 amperes. Once the microcontroller is powered on, turn on the heating system. The red LED of the BSB-LAN adapter should alight. It should flicker occasionally. Now open your webbrowser and open the IP address of BSB-LAN. If MDNS is enabled, you can directly go to http://bsb-lan.local . Otherwise, you can find the IP address of BSB-LAN either in your router, or you connect the microcontroller to your PC and open the Arduino IDE and go to Tools/Serial Monitor and set the serial monitor speed to 115200. Restart the microcontroller, and the IP address will be displayed upon connecting to the network. Generating the device-specific parameter list Once you access BSB-LAN for the first time, you will see that only very few parameters are shown on the device\u2019s web interface. This is because each model of the Siemens controller built into your heating system supports a different set of parameters. Previously, I provided a list of parameters collected from all different kinds of heating systems, but it turned out that this list was ambiguous or even contained errors that we couldn\u2019t fix reliably. This list is still available in release version 2.2.x of BSB-LAN and can be copied from there if needed. However, it is not advisable to do so because the said ambiguities and errors pose too great a risk of misconfiguring the heating system. Instead, it is recommended to click on the \" Device-specific parameter list \" button in BSB-LAN's menu and send the generated list to Frederik (bsb(\u00e4t)code-it.de). From this file, a parameter list can be generated that fits exactly the controller of your heating system. Unfortunately, this process cannot be automated yet, but at least it has to be done just once. These raw data do not contain any settings or other kinds of personal data, just the parameter structure of the heating system. It\u2019s in my own interest to create and return these parameter lists without any delay, but I ask for your understanding if it takes a bit longer due to work or family matters. Once you have received the parameter list (or taken the one from version 2.2.x), you have to replace the existing BSB_LAN_custom_defs.h file with the one sent to you, compile it and flash it again. Now you are ready to access all parameters.","title":"Installation"},{"location":"install.html#installation","text":"Installing BSB-LAN requires three steps: Installing the Arduino IDE in order to flash the BSB-LAN software onto the microcontroller Assembling the hardware parts Connecting BSB-LAN to the heating system","title":"Installation"},{"location":"install.html#installing-the-arduino-ide-and-flashing-bsb-lan","text":"Download and unpack the current BSB-LAN version from the master repository or use git to clone the repository.

If you still have a problem after reading this document as well as the FAQ , please open up a bug report on the project's GitHub page and make sure that you provide us with all the necessary log files and further required details, especially from the Serial Monitor (or SerMo in short). Before doing so, however, make sure that you install the most recent version of BSB-LAN from the master repository (not the release version), even if yours is \"just\" a few days old. Still, a lot could have happned since then :)! Using the Serial Monitor Access the Serial Monitor by going to Tools/Serial Monitor in the Arduino IDE. Set the transmission speed to 115200 at the top right corner of the serial monitor window. Make sure you copy the messages right from the moment your microcontroller boots (indicated by the READY message) until the moment you encounter the problem. Please do not send screenshots, only plain text files. The Serial Monitor in the Arduino IDE currently has a bug that allows you to only copy those parts of the Serial Monitor messages that you can see on the screen. Although this means that copying larger portions of log messages is tedious, you still have to provide the complete log in order to get support. Increasing the size of the Serial Monitor window helps a little. Compiling fails: \"Sketch too big\" Select the Minimal SPIFFS (Large APPS with OTA) partition scheme in the Arduino IDE under Tools/Partition Scheme . If you are using over-the-air updates, you have to flash the software once via USB after changing the partition scheme before OTA updates will work again. No access to web-interface anymore If you have changed the settings in such a way that you cannot access the web-interface anymore, there are two ways to restore the system: If you can flash the device: Configure BSB_LAN_config.h with correct, working settings. Set UseEEPROM to 0 . Flash BSB-LAN onto the microcontroller. You can now access BSB-LAN. Go to \"Settings\" and save the settings. This will store the working settings to the EEPROM. Now edit BSB_LAN_config.h again (!) and set UseEEPROM to 1 and flash BSB-LAN again to the microcontroller. Only now will BSB-LAN read and use the settings from the EEPROM, so you can make further changes in the web-interface. If you cannot flash the device: If you cannot flash the device on site, you can reset BSB-LAN to the last BSB_LAN_config.h setting by connecting two pins before and during booting the microcontroller : ESP32-Olimex: Connect pins 34 and 3V3. ESP32-NodeMCU: Connect pins 21 and 3V3. Arduino Due: Connect pins 31 and 33. If the pins were successfully connected, the built-in LED of the microcontroller will flash slowly for four seconds. Afterwards open the configuration in the web-interface, check all settings in the configuration and save them. This will store the working settings to the EEPROM. Temporary access point on an ESP32-based microcontroller On an ESP32-based microcontroller, BSB-LAN will set up its own wireless access point named BSB-LAN if it cannot connect to any network. In this casee, you can connect to this access point with the password BSB-LPB-PPS-LAN and access BSB-LAN via the IP address http://192.168.4.1 and see if you can fix the configuration this way. Keep in mind that if you have set a passkey or HTTP username and password, these are still required if these details are stored in EEPROM or BSB_LAN_config.h . Category list suddenly so small BSB-LAN needs to detect the heating system's controller to determine the categories to display. If BSB-LAN is not connected to the controller or the detection otherwise fails, only a few universal categories are displayed. Cannot read any parameters / device family is 0 Wrong bus type (BSB instead of LPB or vice versa). If the red LED of the adapter is not on (and ideally slightly flickering), there is a problem with the wiring between the adapter and the heating system. The red LED will come one once the adapter is connected correctly, even if the BSB-LAN adapter isn't even connected to the microcontroller! No data even though the adapter's red LED is on Make sure the adapter is connected to CL+/CL- and not to the third (G+) pin: G+ will drive the LED, but it's not a data line. Make sure you have powered on the microcontroller . You may think that the heating system powers the microcontroller because the LED on the BSB-LAN adapter is on, but it doesn't. You need to power it separately. With the adapter for the Olimex microcontrollers: Make sure that the BSB-LAN adapter board sits exactly in the center of the UEXT connector. It will still fit in, if it's shifted one pin left or right, but it won't work. Make sure the RX/TX pins are set/detected correctly. The startup sequence in the Serial Monitor will show you what pins have are used or have been auto-detected. No or unreliable network connection Try powering the microcontroller via USB from a laptop. We have had many cases where power supplies were unreliable despite having sufficient ratings. Look at the Serial Monitor log to check if the microcontroller could acquire an IP address. If not, then your network settings or physical connection may be faulty. No connection to hidden WiFi network possible Yes, that is a known restriction. The only way to do that is to set the BSSID explicitly in BSB_LAN_config.h . Room temperature (or any other parameter) cannot be set Check BSB-LAN's settings and make sure that write access is enabled and set to standard or complete . Web-interface freezes when making new connection BSB-LAN is not a multi-tasking system. This means it can attend to one task at a time. So even if a URL command is aborted (by closing the browser window), BSB-LAN might not detect this and only start serving new requests once the previous one is finished. The Serial Monitor is not showing readable data Make sure the speed is set correctly to 115200 bps.

BSB-LAN is a software /hardware solution for accessing the \u201cBoiler-System-Bus\u201d (BSB) , the \u201cLocal-Process-Bus (LPB)\u201d and the \u201cPunkt-zu-Punkt-Schnittstelle\u201d (PPS) . The BSB-LAN hardware is available for various ESP32 -based microcontrollers (ESP32 NodeMCU, Olimex EVB, Olimex POE-ISO) as well as for an Arduino Due with Ethernet shield. It allows accessing the heating systems from Atlantic, Br\u00f6tje, Elco and many other manufacturers via LAN/WLAN, provided that they use one of the Siemens controllers listed below. BSB-LAN makes it possible to monitor and control the heating and log any given values. This project supports almost all parameters available on the heating systems and can be a more comprehensive and cost-effective alternative to the OZW 672, OCI 700 or Remocon Net B. Optional integration into existing smart home systems such as Home Assistant , ioBroker , openHAB , Node-RED , Homebridge , Jeedom , SmartHomeNG , Volksz\u00e4hler , FHEM , HomeMatic , Loxone, IP-Symcon or EDOMI is possible via MQTT , JSON or HTTP access . The adapter can also be used as a standalone logger without LAN or Internet connection when using a microSD card. Temperature and humidity sensors can also be connected and their data can also be logged and analyzed. The option of integrating your own code into the BSB-LAN software also offers a wide range of expansion options. Where and how do I begin? You are an experienced user? Head on to the quickstart instructions . Otherwise (or if you run into problems), please read on! Is my heating system supported by BSB-LAN? Please go to the list of supported heating systems . If you already know that your system is supported, find out more about the BSB-LAN adapter and where to get it. If you already have the adapter, you may want to know how to install the adapter . If you have installed the adapter, you will need to configure BSB-LAN . Once you have everything up and running, find out about how to use BSB-LAN or learn more about the ways to ingetrate BSB-LAN into home automation systems .

In order to connect to your heating system with a microcontroller, you need to have an adapter board that does the necessary logic-level conversion: The adapter is then plugged right onto the microcontroller, either underneath the pins of the ESP32-NodeMCU or onto the UEXT connector of the Olimex: The two different types of ESP32 adapters (Olimex and ESP32-NoceMCU) only vary in the location of their connectors, the other parts of the board are identical. The Arduino Due board contains an EEPROM chip because the Due does not come with on-board EEPROM. Therefore, you can re-use the Arduino Due board on an ESP32 microcontroller (if you connect the correct pins with wires), but you cannot use an adapter for the ESP32 on an Arduino Due. Suitable microcontrollers BSB-LAN can be installed on three different types of microcontrollers: ESP32-Olimex ESP32-NodeMCU (30 pin version only!) and Arduino Due. Olimex produces several kinds of boards: We recommend either the Olimex ESP32-EVB or the Olimex ESP32-POE-ISO . The simple POE version (without the \"ISO\") is not recommended because it does not allow to be connected to PoE Ethernet and USB at the same time. The Arduino Due requires an Ethernet Shield in order to access the local network. Each of the different controllers have their advantages and disadvantages: Functionality ESP32-Olimex ESP32-POE-ISO ESP32-NodeMCU Arduino Due Ethernet/LAN X X - X WiFi/WLAN X X X - Over-the-air updateable X X X - Built-in micro-SD card X X - - Accessible GPIOs 2 (GPIO13/16) some some many","title":"Der BSB-LAN Adapter"},{"location":"de/bus_systems.html","text":"The BSB/LPB/PPS Bus Developed at the end of the last millenium based on the BatiBUS (more information can be found here and here ), many Siemens heating system controllers still use the same kind of physical bus to \"talk\" to room units as well as other heating devices. While a bus speed of a mere 4800 bits per second might sound anachronistic these days, it still provides for a stable and robust transmission protocol that is even today perfectly sufficient when it comes to transmitting short messages of a few dozen bytes over lines sometimes as long as one kilometer. The bus topology also allows you to connect BSB-LAN at any point: At the room unit, at the heating system or anywhere where the bus lines are available. You can even add the two wires for BSB-LAN in an already \"occupied\" slot, and it won't harm the other device (proper installation assumed). On top of the same physical layer, three bus systems, BSB, LPB and PPS, cater for different tasks, and while BSB and LPB should always be preferred if available, PPS nevertheless provides a set of parameters that is usually quite enough for the average user. BSB-LAN runs on any of these busses and swapping between them is just changing a few settings away. The Boiler System Bus (BSB) BSB is the most common bus system in Siemens controllers for the last 10-15 years. It is the successor of the PPS system with which it shares the same physical parameters, but is much more versatile: Instead of just a few dozen parameters, it can access hundreds of parameters and group them into various categories for easier navigation. It is a transaction-based protocol where most messages are being sent from one device to another and the recipient returning some kind of feedback, for example whether the task could be completed or whether it contained invalid data. While BSB is capable of addressing multiple devices on the bus, it is not used in systems with more than one heating device. The heating device always has the ID 0 , the display unit on the heating system has the ID 10 (or 0x0A in hexadecimal) and the standard room unit has the ID 6 . BSB-LAN has the ID 66 or 0x42 in hexadecimal. Room units that \"speak\" BSB are, for example, the QAA55 and the QAA75. The Local Process Bus (LPB) LPB was introduced more or less around the same time as PPS which it complemented in terms of communication with other heating devices: While PPS was used to communicate with the room unit, LPB was used to send commands from one main heating device to one or more auxilliary heating devices, for example in a cascade setup. At that time, most of the information transmitted via LPB was related to the internals of the heating system (such as sensor data or internal setpoint temperatures), whereas the parameters relevant for the user (such as comfort temperature setpoint etc.) were only available via PPS. Nowadays, heating devices that offer both LPB and BSB have the same kind of parameter data available on both bus systems. LPB uses a specific addressing scheme with segments and devices. Each segment from 0 to 15 can contain up to 15 devices (from 1 to 15). When writing these addresses, segment and device are separated by a colon: 00:01 or 04:03 . To convert the segment-based address into the destination ID required for BSB-LAN, the formula is as this: SEGMENT multiplied by 16 plus DEVICE minus one. Example: Device 3 in segment 4 equals to 4 * 16 + 3 - 1 = 66. The main heating unit is by definition 00:01 , so this equals to a destination ID 0. To learn more about the LPB system and how it should be deployed, you may refer to these two documents from the end of the 1990s, one covers the basic system data that covers the conceptualization of an LPB network, and the other one deals with the basic engineering data and provides details about cable lengths and diameters etc. Except for some Weishaut heaters, room units are not connected to the heating system via LPB. Newer models use BSB for this task while older models use either PPS or in some cases also OpenTherm. The Point-to-Point Interface (PPS) The Point-to-Point Interface (PPS deriving from the German term \"Punkt-zu-Punkt Schnittstelle\") is compatible to the other systems on a physical layer, but not in the way message telegrams are being exchanged. While BSB and LPB talk to each other by sending telegrams and acknowledging their receipt respectively, PPS is dominated by the heating unit. The heating unit constantly sends its data to the room unit and tells the room unit when and what kind of information it should send. So it may take up to a few minutes until a value that is set in BSB-LAN is actually requested by the heating system and shown there. It is also a very timing sensitive protocol, therefore long other tasks that BSB-LAN is told to do will lead to a temporary interruption and possible error message on the heating system. However, after a short while, this should be clearing by itself when the two components \"talk\" to each other again. Other than BSB and LPB, changes made in BSB-LAN do not take immediate effect. Changing values, for example like the room temperature comfort setpoint, will be stored internally in BSB-LAN first to be sent out to the heating system once it tells the room unit (i.e. BSB-LAN) to do so. This may take up to a minute or so, so one should not be confused that settings do not show up on the heater immediately, as is the case with BSB and LPB. With PPS, BSB-LAN can run in two modes: passive and as a room unit. In passive mode, BSB-LAN can just listen to the data exchanged between the room unit and the heating device. It is not possible to send one's own data, for the simple fact that it would be overwritten in no time by the same type of data coming from the room unit. In order to send parameter data to the heating system, BSB-LAN mus run in \"room unit\" mode, and this means that any room unit will have to be removed from the heating system. In this case, it is especially important to regularly send a room temperature value to BSB-LAN which in turn will send this value to the heating device. Only if the heater runs solely on outside temperature then this value can be ignored. BSB-LAN stores some values in its non-volatile EEPROM, but some values need to be set anew after a reboot, such as the room temperature setpoint. This is to prevent to store a parameter value that has become invalid but is still sent as it is stored in the EEPROM. Room units commonly used with heating systems that support PPS are the QAA50 and the QAA70.","title":"Der BSB/LPB/PPS Bus"},{"location":"de/configure.html","text":"Configuration There are two ways to configure BSB-LAN: Through the configuration file BSB_LAN_config.h Through the web-interface by calling http://bsb-lan.local/C (or the corresponding IP address) For the initial configuration, some settings have to be configured in the configuration file (such as language and network settings). Any further changes can be done also in the web-interface. It may, however, be useful to do the configuration (also) in the configuration file in case one needs to change the microcontroller. Almost all settings exist also in the web-interface and vice versa. On an ESP32-based microcontroller, BSB-LAN will set up its own wireless access point named BSB-LAN if it cannot connect to any network. So even without any further configuration, you can connect to this access point with the password BSB-LPB-PPS-LAN and access BSB-LAN via the IP address http://192.168.4.1 and proceed with the configuration via this way. Keep in mind that if you have set a passkey or HTTP username and password, these are still required if these details are stored in EEPROM or BSB_LAN_config.h . Configuration through `BSB_LAN_config.h`` The configuration file consists of variables that are used in other parts of BSB-LAN. It is therefore important to only change the contents of the variables (i.e. the settings) and not the type of the variables. So if there is for example the setting byte ip_addr[4] = {192,168,178,88}; you must not alter the byte ip_addr[4] = part, only the contents, in this case the comma-separated IP address. Configuration through the web-interface Configuring BSB-LAN through the web-interface is pretty straightforward, as you don't have to deal with variable names but clear descriptions. Initially, only a selected number of configuration options are displayed in the webinterface. To have access to all of them, you have to set the \"extended configuration\" option to \"on\".

As a prerequisite, a MQTT broker (such as mosquitto is needed, either running locally or via making use of a public service. Some home automation systems such as Home Assistant offer the installation of mosquitto as part of their software. In BSB-LAN, you need to make or enable at least the following configurations: Set Logging mode (additionally) to Send to MQTT Broker . Set Log Interval to the time (in seconds) you want the log parameters to be published. Select up to 20 Log Parameters you want to be sent to your home automation system. Set MQTT Usage to plain text Set MQTT Broker Server to the hostname of your MQTT broker (such as the mosquitto server) If your home automation system supports MQTT auto-discovery (as is the case with Home Assistant), you can call URL command /M1 and BSB-LAN will send auto-discovery messages for all available parameters to the MQTT broker and thus to the home automation system. You may have to clean up afterwards or send a removal message for all these parameters using URL command /M0 . Every time a query is made in BSB-LAN or a parameter changes its value through the room unit, the new value will be sent to the MQTT broker, so even changes made outside of BSB-LAN should be updated into the home automation system, which is why the MQTT approach is the recommended way to connect to a home automation system. Examples for querying or setting parameters via MQTT would look like this (using mosquitto): Query the outside temperature (parameter 8700): mosquitto_pub -h my.mosquitto-broker.local -u USER -P PASSWORD -m \"8700\" -t BSB-LAN -d Set the comfort temperature setpoint (parameter 710) to 20 degrees: mosquitto_pub -h my.mosquitto-broker.local -u USER -P PASSWORD -m \"S700=20\" -t BSB-LAN -d Exchanging data via JSON BSB-LAN allows to query and set parameters via JSON structures and also provides numerous information about the parameters and category structures this way. The JSON API is accessd via URL commands and the openapi.yaml file provided in this repository can be used with Swagger to explore its possibilities and functionalitites. Using supported modules for specific home automation systems For some systems, specific modules exist that can be used to access BSB-LAN seamlessly: Home Assistant While the official plugin no longer works, the MQTT approach above works well with Home Assistant.

Exchanging data via URL commands and screen scraping For simpler solutions, using the URL commands to query and set parameters can be used to control BSB-LAN from other systems. Screen scraping is possible since the project tries not to break certain ways of displaying data, so that parsing with regular expressions remains feasible.

Download and install the Arduino IDE for your system. Connect your microcontroller (ESP32 or Arduino Due) to your computer and start the Arduino IDE. Go to Tools/Board/Board Manager and make sure that the framework for your board is installed (\"esp32 by Espressif Systems\" for ESP32 microcontroller, \"Arduino SAM Boards (32-bits ARM Cortex-M3) by Arduino\" for Arduino Due microcontroller) Again, go to Tools/Board and select your microcontroller: ESP32 Dev Module for the Joy-It ESP32 NodeMCU. Olimex ESP32-EVB for the ESP32-based Olimex EVB . Olimex ESP32-POE-ISO for the ESP32-based Olimex POE ISO Arduino Due (Programming Port) for the Arduino Due. Do not use the Native USB Port here ! Again, go to Tools/Board and select the proper upload speed (460800 for ESP32, 115200 for Arduino Due). For ESP32-based microcontrollers, again, go to Tools/Board and select \"Minimal SPIFFS (Large APPS with OTA)\" for partition scheme ( do not confuse this with the similar \"Minimal\" partition scheme which is different and not working in our case). If you don't set the correct parition scheme, the firmware will not fit into the ESP32! Go to File/Open and navigate to the BSB_LAN folder and double-click on BSB_LAN.ino . The project will open. You may now proceed to configure BSB-LAN. When you are done configuring, go to Sketch/Upload and upload the BSB-LAN software to the microcontroller. Subsequent updates on ESP32-based microcontrollers \"over the air\" (OTA) If you are running BSB-LAN on an ESP32-based microcontroller and have enabled Over-the-Air Updates in the settings , you can perform future updates of BSB-LAN using your browser. To do that, instead of using Sketch/Upload , you need to select Sketch/Export Compiled Binary . This will create a build folder in your BSB-LAN folder in which you will find among others the file BSB_LAN.ino.bin . Now open http://bsb-lan.local:8080 and select and upload that file. Do not interrupt the upload process. You may try to access BSB-LAN from a different browser window to see if the process is completed. Please take note that this only applies to ESP32-based microcontrollers. Arduinos do not support this functionality. Assembling the BSB-LAN adapter You can either get a fully assembled adapter from Frederik (bsb(\u00e4t)code-it.de) or build one on your own (see the folder schematics for the schematics). Once you have the BSB-LAN adapter ready, you just need to plug it into the microcontroller. If you are using an Olimex microcontroller, double-check that the adapter really sits in the center of the connector, because it still fits even if it is moved by one pin row to the left or right. Connecting BSB-LAN to the heating system Once the microcontroller and the BSB-LAN adapter are ready, perform the following steps to connect BSB-LAN to the heating system: Unplug the microcontroller from your computer and turn off your heating system. Locate the BSB/LPB/PPS connectors. You may have to open your heating system for that. Have a look at the list of supported heating systems to get an idea where the pins are located. Do all this at your own risk! Especially take care to prevent electrostatic discharge (ESD) which can destroy both BSB-LAN and the heating controller! Now plug the BSB-LAN adapter onto the microcontroller and connect the + screw connector to the CL+ (BSB), DB (LPB) or A6 (PPS, different connector names are possible) connector, and the - screw connector to the CL- (BSB), MB (LPB) or M (PPS) connector. If there is no empty connector, there is no problem adding the wires for BSB-LAN to an already \"used\" connector, provided the wires are inserted carefully. Now you need to power on the microcontroller. Take note that the heating system does not power the microcontroller, even if the BSB-LAN adapter's LED turns on when you connect it to the heating system. You need to supply power to the microcontroller via its USB port (or via PoE on the Olimex POE-ISO). Make sure to use a stable power supply with at least 2 amperes. Once the microcontroller is powered on, turn on the heating system. The red LED of the BSB-LAN adapter should alight. It should flicker occasionally. Now open your webbrowser and open the IP address of BSB-LAN. If MDNS is enabled, you can directly go to http://bsb-lan.local . Otherwise, you can find the IP address of BSB-LAN either in your router, or you connect the microcontroller to your PC and open the Arduino IDE and go to Tools/Serial Monitor and set the serial monitor speed to 115200. Restart the microcontroller, and the IP address will be displayed upon connecting to the network. Generating the device-specific parameter list Once you access BSB-LAN for the first time, you will see that only very few parameters are shown on the device\u2019s web interface. This is because each model of the Siemens controller built into your heating system supports a different set of parameters. Previously, I provided a list of parameters collected from all different kinds of heating systems, but it turned out that this list was ambiguous or even contained errors that we couldn\u2019t fix reliably. This list is still available in release version 2.2.x of BSB-LAN and can be copied from there if needed. However, it is not advisable to do so because the said ambiguities and errors pose too great a risk of misconfiguring the heating system. Instead, it is recommended to click on the \" Device-specific parameter list \" button in BSB-LAN's menu and send the generated list to Frederik (bsb(\u00e4t)code-it.de). From this file, a parameter list can be generated that fits exactly the controller of your heating system. Unfortunately, this process cannot be automated yet, but at least it has to be done just once. These raw data do not contain any settings or other kinds of personal data, just the parameter structure of the heating system. It\u2019s in my own interest to create and return these parameter lists without any delay, but I ask for your understanding if it takes a bit longer due to work or family matters. Once you have received the parameter list (or taken the one from version 2.2.x), you have to replace the existing BSB_LAN_custom_defs.h file with the one sent to you, compile it and flash it again. Now you are ready to access all parameters.","title":"Zusammenbauen"},{"location":"de/quickstart.html","text":"Quickstart instructions These quickstart instructions are for users who are familiar with installing and configuring software on their computer.

We have compiled a list of working models from various heating system manufacturers who have been confirmed working with BSB-LAN, although there is no 100% guarantee that the manufacturers keep the model name but change the controller to a different system. So always make sure to double-check that the right connectors are available. Here are a few examples from heating controllers and the connectors that are used to connect to BSB-LAN. Some connectors have three pins, some have two pins. If there are three pins, make sure you choose the correct two (CL+ and CL-) as the third von (G+) is to provide background lighting for the room unit. It won't harm BSB-LAN, but it might be misleading because BSB-LAN's LED will be on even though it's not connected to the right pin.

If you still have a problem after reading this document as well as the FAQ , please open up a bug report on the project's GitHub page and make sure that you provide us with all the necessary log files and further required details, especially from the Serial Monitor (or SerMo in short). Before doing so, however, make sure that you install the most recent version of BSB-LAN from the master repository (not the release version), even if yours is \"just\" a few days old. Still, a lot could have happned since then :)! Using the Serial Monitor Access the Serial Monitor by going to Tools/Serial Monitor in the Arduino IDE. Set the transmission speed to 115200 at the top right corner of the serial monitor window. Make sure you copy the messages right from the moment your microcontroller boots (indicated by the READY message) until the moment you encounter the problem. Please do not send screenshots, only plain text files. The Serial Monitor in the Arduino IDE currently has a bug that allows you to only copy those parts of the Serial Monitor messages that you can see on the screen. Although this means that copying larger portions of log messages is tedious, you still have to provide the complete log in order to get support. Increasing the size of the Serial Monitor window helps a little. Compiling fails: \"Sketch too big\" Select the Minimal SPIFFS (Large APPS with OTA) partition scheme in the Arduino IDE under Tools/Partition Scheme . If you are using over-the-air updates, you have to flash the software once via USB after changing the partition scheme before OTA updates will work again. No access to web-interface anymore If you have changed the settings in such a way that you cannot access the web-interface anymore, there are two ways to restore the system: If you can flash the device: Configure BSB_LAN_config.h with correct, working settings. Set UseEEPROM to 0 . Flash BSB-LAN onto the microcontroller. You can now access BSB-LAN. Go to \"Settings\" and save the settings. This will store the working settings to the EEPROM. Now edit BSB_LAN_config.h again (!) and set UseEEPROM to 1 and flash BSB-LAN again to the microcontroller. Only now will BSB-LAN read and use the settings from the EEPROM, so you can make further changes in the web-interface. If you cannot flash the device: If you cannot flash the device on site, you can reset BSB-LAN to the last BSB_LAN_config.h setting by connecting two pins before and during booting the microcontroller : ESP32-Olimex: Connect pins 34 and 3V3. ESP32-NodeMCU: Connect pins 21 and 3V3. Arduino Due: Connect pins 31 and 33. If the pins were successfully connected, the built-in LED of the microcontroller will flash slowly for four seconds. Afterwards open the configuration in the web-interface, check all settings in the configuration and save them. This will store the working settings to the EEPROM. Temporary access point on an ESP32-based microcontroller On an ESP32-based microcontroller, BSB-LAN will set up its own wireless access point named BSB-LAN if it cannot connect to any network. In this casee, you can connect to this access point with the password BSB-LPB-PPS-LAN and access BSB-LAN via the IP address http://192.168.4.1 and see if you can fix the configuration this way. Keep in mind that if you have set a passkey or HTTP username and password, these are still required if these details are stored in EEPROM or BSB_LAN_config.h . Category list suddenly so small BSB-LAN needs to detect the heating system's controller to determine the categories to display. If BSB-LAN is not connected to the controller or the detection otherwise fails, only a few universal categories are displayed. Cannot read any parameters / device family is 0 Wrong bus type (BSB instead of LPB or vice versa). If the red LED of the adapter is not on (and ideally slightly flickering), there is a problem with the wiring between the adapter and the heating system. The red LED will come one once the adapter is connected correctly, even if the BSB-LAN adapter isn't even connected to the microcontroller! No data even though the adapter's red LED is on Make sure the adapter is connected to CL+/CL- and not to the third (G+) pin: G+ will drive the LED, but it's not a data line. Make sure you have powered on the microcontroller . You may think that the heating system powers the microcontroller because the LED on the BSB-LAN adapter is on, but it doesn't. You need to power it separately. With the adapter for the Olimex microcontrollers: Make sure that the BSB-LAN adapter board sits exactly in the center of the UEXT connector. It will still fit in, if it's shifted one pin left or right, but it won't work. Make sure the RX/TX pins are set/detected correctly. The startup sequence in the Serial Monitor will show you what pins have are used or have been auto-detected. No or unreliable network connection Try powering the microcontroller via USB from a laptop. We have had many cases where power supplies were unreliable despite having sufficient ratings. Look at the Serial Monitor log to check if the microcontroller could acquire an IP address. If not, then your network settings or physical connection may be faulty. No connection to hidden WiFi network possible Yes, that is a known restriction. The only way to do that is to set the BSSID explicitly in BSB_LAN_config.h . Room temperature (or any other parameter) cannot be set Check BSB-LAN's settings and make sure that write access is enabled and set to standard or complete . Web-interface freezes when making new connection BSB-LAN is not a multi-tasking system. This means it can attend to one task at a time. So even if a URL command is aborted (by closing the browser window), BSB-LAN might not detect this and only start serving new requests once the previous one is finished. The Serial Monitor is not showing readable data Make sure the speed is set correctly to 115200 bps. Make sure the correct port is selected.","title":"Fehlersuche"},{"location":"de/using.html","text":"Using BSB-LAN Controlling the heating system via the web-interface As a first step \u2013 or if you just want to turn your heating system on or off \u2013 you can simply open the BSB-LAN web-interface and go to the Settings menu.

In order to connect to your heating system with a microcontroller, you need to have an adapter board that does the necessary logic-level conversion: The adapter is then plugged right onto the microcontroller, either underneath the pins of the ESP32-NodeMCU or onto the UEXT connector of the Olimex: The two different types of ESP32 adapters (Olimex and ESP32-NoceMCU) only vary in the location of their connectors, the other parts of the board are identical. The Arduino Due board contains an EEPROM chip because the Due does not come with on-board EEPROM. Therefore, you can re-use the Arduino Due board on an ESP32 microcontroller (if you connect the correct pins with wires), but you cannot use an adapter for the ESP32 on an Arduino Due. Suitable microcontrollers BSB-LAN can be installed on three different types of microcontrollers: ESP32-Olimex ESP32-NodeMCU (30 pin version only!) and Arduino Due. Olimex produces several kinds of boards: We recommend either the Olimex ESP32-EVB or the Olimex ESP32-POE-ISO . The simple POE version (without the \"ISO\") is not recommended because it does not allow to be connected to PoE Ethernet and USB at the same time. The Arduino Due requires an Ethernet Shield in order to access the local network. Each of the different controllers have their advantages and disadvantages: Functionality ESP32-Olimex ESP32-POE-ISO ESP32-NodeMCU Arduino Due Ethernet/LAN X X - X WiFi/WLAN X X X - Over-the-air updateable X X X - Built-in micro-SD card X X - - Accessible GPIOs 2 (GPIO13/16) some some many","title":"L'adaptateur BSB-LAN"},{"location":"fr/bus_systems.html","text":"The BSB/LPB/PPS Bus Developed at the end of the last millenium based on the BatiBUS (more information can be found here and here ), many Siemens heating system controllers still use the same kind of physical bus to \"talk\" to room units as well as other heating devices. While a bus speed of a mere 4800 bits per second might sound anachronistic these days, it still provides for a stable and robust transmission protocol that is even today perfectly sufficient when it comes to transmitting short messages of a few dozen bytes over lines sometimes as long as one kilometer. The bus topology also allows you to connect BSB-LAN at any point: At the room unit, at the heating system or anywhere where the bus lines are available. You can even add the two wires for BSB-LAN in an already \"occupied\" slot, and it won't harm the other device (proper installation assumed). On top of the same physical layer, three bus systems, BSB, LPB and PPS, cater for different tasks, and while BSB and LPB should always be preferred if available, PPS nevertheless provides a set of parameters that is usually quite enough for the average user. BSB-LAN runs on any of these busses and swapping between them is just changing a few settings away. The Boiler System Bus (BSB) BSB is the most common bus system in Siemens controllers for the last 10-15 years. It is the successor of the PPS system with which it shares the same physical parameters, but is much more versatile: Instead of just a few dozen parameters, it can access hundreds of parameters and group them into various categories for easier navigation. It is a transaction-based protocol where most messages are being sent from one device to another and the recipient returning some kind of feedback, for example whether the task could be completed or whether it contained invalid data. While BSB is capable of addressing multiple devices on the bus, it is not used in systems with more than one heating device. The heating device always has the ID 0 , the display unit on the heating system has the ID 10 (or 0x0A in hexadecimal) and the standard room unit has the ID 6 . BSB-LAN has the ID 66 or 0x42 in hexadecimal. Room units that \"speak\" BSB are, for example, the QAA55 and the QAA75. The Local Process Bus (LPB) LPB was introduced more or less around the same time as PPS which it complemented in terms of communication with other heating devices: While PPS was used to communicate with the room unit, LPB was used to send commands from one main heating device to one or more auxilliary heating devices, for example in a cascade setup. At that time, most of the information transmitted via LPB was related to the internals of the heating system (such as sensor data or internal setpoint temperatures), whereas the parameters relevant for the user (such as comfort temperature setpoint etc.) were only available via PPS. Nowadays, heating devices that offer both LPB and BSB have the same kind of parameter data available on both bus systems. LPB uses a specific addressing scheme with segments and devices. Each segment from 0 to 15 can contain up to 15 devices (from 1 to 15). When writing these addresses, segment and device are separated by a colon: 00:01 or 04:03 . To convert the segment-based address into the destination ID required for BSB-LAN, the formula is as this: SEGMENT multiplied by 16 plus DEVICE minus one. Example: Device 3 in segment 4 equals to 4 * 16 + 3 - 1 = 66. The main heating unit is by definition 00:01 , so this equals to a destination ID 0. To learn more about the LPB system and how it should be deployed, you may refer to these two documents from the end of the 1990s, one covers the basic system data that covers the conceptualization of an LPB network, and the other one deals with the basic engineering data and provides details about cable lengths and diameters etc. Except for some Weishaut heaters, room units are not connected to the heating system via LPB. Newer models use BSB for this task while older models use either PPS or in some cases also OpenTherm. The Point-to-Point Interface (PPS) The Point-to-Point Interface (PPS deriving from the German term \"Punkt-zu-Punkt Schnittstelle\") is compatible to the other systems on a physical layer, but not in the way message telegrams are being exchanged. While BSB and LPB talk to each other by sending telegrams and acknowledging their receipt respectively, PPS is dominated by the heating unit. The heating unit constantly sends its data to the room unit and tells the room unit when and what kind of information it should send. So it may take up to a few minutes until a value that is set in BSB-LAN is actually requested by the heating system and shown there. It is also a very timing sensitive protocol, therefore long other tasks that BSB-LAN is told to do will lead to a temporary interruption and possible error message on the heating system. However, after a short while, this should be clearing by itself when the two components \"talk\" to each other again. Other than BSB and LPB, changes made in BSB-LAN do not take immediate effect. Changing values, for example like the room temperature comfort setpoint, will be stored internally in BSB-LAN first to be sent out to the heating system once it tells the room unit (i.e. BSB-LAN) to do so. This may take up to a minute or so, so one should not be confused that settings do not show up on the heater immediately, as is the case with BSB and LPB. With PPS, BSB-LAN can run in two modes: passive and as a room unit. In passive mode, BSB-LAN can just listen to the data exchanged between the room unit and the heating device. It is not possible to send one's own data, for the simple fact that it would be overwritten in no time by the same type of data coming from the room unit. In order to send parameter data to the heating system, BSB-LAN mus run in \"room unit\" mode, and this means that any room unit will have to be removed from the heating system. In this case, it is especially important to regularly send a room temperature value to BSB-LAN which in turn will send this value to the heating device. Only if the heater runs solely on outside temperature then this value can be ignored. BSB-LAN stores some values in its non-volatile EEPROM, but some values need to be set anew after a reboot, such as the room temperature setpoint. This is to prevent to store a parameter value that has become invalid but is still sent as it is stored in the EEPROM. Room units commonly used with heating systems that support PPS are the QAA50 and the QAA70.","title":"Les BSB/LPB/PS bus"},{"location":"fr/homeautomation.html","text":"Connecting BSB-LAN to home automation systems BSB-LAN provides four ways to connect to home automation systems: Exchanging data via MQTT (recommended) Exchanging data via JSON Using supported modules for specific home automation systems Exchanging data via URL commands and screen scraping Exchanging data via MQTT This is the recommended way to connect BSB-LAN to home automation systems because it allows seamless exchange of data. As a prerequisite, a MQTT broker (such as mosquitto is needed, either running locally or via making use of a public service. Some home automation systems such as Home Assistant offer the installation of mosquitto as part of their software. In BSB-LAN, you need to make or enable at least the following configurations: Set Logging mode (additionally) to Send to MQTT Broker . Set Log Interval to the time (in seconds) you want the log parameters to be published. Select up to 20 Log Parameters you want to be sent to your home automation system. Set MQTT Usage to plain text Set MQTT Broker Server to the hostname of your MQTT broker (such as the mosquitto server) If your home automation system supports MQTT auto-discovery (as is the case with Home Assistant), you can call URL command /M1 and BSB-LAN will send auto-discovery messages for all available parameters to the MQTT broker and thus to the home automation system. You may have to clean up afterwards or send a removal message for all these parameters using URL command /M0 . Every time a query is made in BSB-LAN or a parameter changes its value through the room unit, the new value will be sent to the MQTT broker, so even changes made outside of BSB-LAN should be updated into the home automation system, which is why the MQTT approach is the recommended way to connect to a home automation system. Examples for querying or setting parameters via MQTT would look like this (using mosquitto): Query the outside temperature (parameter 8700): mosquitto_pub -h my.mosquitto-broker.local -u USER -P PASSWORD -m \"8700\" -t BSB-LAN -d Set the comfort temperature setpoint (parameter 710) to 20 degrees: mosquitto_pub -h my.mosquitto-broker.local -u USER -P PASSWORD -m \"S700=20\" -t BSB-LAN -d Exchanging data via JSON BSB-LAN allows to query and set parameters via JSON structures and also provides numerous information about the parameters and category structures this way. The JSON API is accessd via URL commands and the openapi.yaml file provided in this repository can be used with Swagger to explore its possibilities and functionalitites. Using supported modules for specific home automation systems For some systems, specific modules exist that can be used to access BSB-LAN seamlessly: Home Assistant While the official plugin no longer works, the MQTT approach above works well with Home Assistant. For the details of the implementation, you may also refer to these tutorials: GitHub user @ryann72 wrote detailed instructions for BSB-LAN and HomeAssistant/Mosquitto .

Exchanging data via URL commands and screen scraping For simpler solutions, using the URL commands to query and set parameters can be used to control BSB-LAN from other systems. Screen scraping is possible since the project tries not to break certain ways of displaying data, so that parsing with regular expressions remains feasible. Nevertheless, for most scenarios one of the other options will probably be preferrable.","title":"Connecter \u00e0 la Smart Home"},{"location":"fr/install.html","text":"Installation Installing BSB-LAN requires three steps: Installing the Arduino IDE in order to flash the BSB-LAN software onto the microcontroller Assembling the hardware parts Connecting BSB-LAN to the heating system Installing the Arduino IDE and flashing BSB-LAN Download and unpack the current BSB-LAN version from the master repository or use git to clone the repository. Navigate to the BSB_LAN folder and rename the following files: BSB_LAN_custom_defs.h.default to BSB_LAN_custom_defs.h BSB_LAN_config.h.default to BSB_LAN_config.h . Download and install the Arduino IDE for your system. Connect your microcontroller (ESP32 or Arduino Due) to your computer and start the Arduino IDE. Go to Tools/Board/Board Manager and make sure that the framework for your board is installed (\"esp32 by Espressif Systems\" for ESP32 microcontroller, \"Arduino SAM Boards (32-bits ARM Cortex-M3) by Arduino\" for Arduino Due microcontroller) Again, go to Tools/Board and select your microcontroller: ESP32 Dev Module for the Joy-It ESP32 NodeMCU. Olimex ESP32-EVB for the ESP32-based Olimex EVB . Olimex ESP32-POE-ISO for the ESP32-based Olimex POE ISO Arduino Due (Programming Port) for the Arduino Due. Do not use the Native USB Port here ! Again, go to Tools/Board and select the proper upload speed (460800 for ESP32, 115200 for Arduino Due). For ESP32-based microcontrollers, again, go to Tools/Board and select \"Minimal SPIFFS (Large APPS with OTA)\" for partition scheme ( do not confuse this with the similar \"Minimal\" partition scheme which is different and not working in our case). If you don't set the correct parition scheme, the firmware will not fit into the ESP32! Go to File/Open and navigate to the BSB_LAN folder and double-click on BSB_LAN.ino . The project will open. You may now proceed to configure BSB-LAN. When you are done configuring, go to Sketch/Upload and upload the BSB-LAN software to the microcontroller. Subsequent updates on ESP32-based microcontrollers \"over the air\" (OTA) If you are running BSB-LAN on an ESP32-based microcontroller and have enabled Over-the-Air Updates in the settings , you can perform future updates of BSB-LAN using your browser. To do that, instead of using Sketch/Upload , you need to select Sketch/Export Compiled Binary . This will create a build folder in your BSB-LAN folder in which you will find among others the file BSB_LAN.ino.bin . Now open http://bsb-lan.local:8080 and select and upload that file. Do not interrupt the upload process. You may try to access BSB-LAN from a different browser window to see if the process is completed. Please take note that this only applies to ESP32-based microcontrollers. Arduinos do not support this functionality. Assembling the BSB-LAN adapter You can either get a fully assembled adapter from Frederik (bsb(\u00e4t)code-it.de) or build one on your own (see the folder schematics for the schematics). Once you have the BSB-LAN adapter ready, you just need to plug it into the microcontroller. If you are using an Olimex microcontroller, double-check that the adapter really sits in the center of the connector, because it still fits even if it is moved by one pin row to the left or right. Connecting BSB-LAN to the heating system Once the microcontroller and the BSB-LAN adapter are ready, perform the following steps to connect BSB-LAN to the heating system: Unplug the microcontroller from your computer and turn off your heating system. Locate the BSB/LPB/PPS connectors. You may have to open your heating system for that. Have a look at the list of supported heating systems to get an idea where the pins are located. Do all this at your own risk! Especially take care to prevent electrostatic discharge (ESD) which can destroy both BSB-LAN and the heating controller! Now plug the BSB-LAN adapter onto the microcontroller and connect the + screw connector to the CL+ (BSB), DB (LPB) or A6 (PPS, different connector names are possible) connector, and the - screw connector to the CL- (BSB), MB (LPB) or M (PPS) connector. If there is no empty connector, there is no problem adding the wires for BSB-LAN to an already \"used\" connector, provided the wires are inserted carefully. Now you need to power on the microcontroller. Take note that the heating system does not power the microcontroller, even if the BSB-LAN adapter's LED turns on when you connect it to the heating system. You need to supply power to the microcontroller via its USB port (or via PoE on the Olimex POE-ISO). Make sure to use a stable power supply with at least 2 amperes. Once the microcontroller is powered on, turn on the heating system. The red LED of the BSB-LAN adapter should alight. It should flicker occasionally. Now open your webbrowser and open the IP address of BSB-LAN. If MDNS is enabled, you can directly go to http://bsb-lan.local . Otherwise, you can find the IP address of BSB-LAN either in your router, or you connect the microcontroller to your PC and open the Arduino IDE and go to Tools/Serial Monitor and set the serial monitor speed to 115200. Restart the microcontroller, and the IP address will be displayed upon connecting to the network. Generating the device-specific parameter list Once you access BSB-LAN for the first time, you will see that only very few parameters are shown on the device\u2019s web interface. This is because each model of the Siemens controller built into your heating system supports a different set of parameters. Previously, I provided a list of parameters collected from all different kinds of heating systems, but it turned out that this list was ambiguous or even contained errors that we couldn\u2019t fix reliably. This list is still available in release version 2.2.x of BSB-LAN and can be copied from there if needed. However, it is not advisable to do so because the said ambiguities and errors pose too great a risk of misconfiguring the heating system. Instead, it is recommended to click on the \" Device-specific parameter list \" button in BSB-LAN's menu and send the generated list to Frederik (bsb(\u00e4t)code-it.de). From this file, a parameter list can be generated that fits exactly the controller of your heating system. Unfortunately, this process cannot be automated yet, but at least it has to be done just once. These raw data do not contain any settings or other kinds of personal data, just the parameter structure of the heating system. It\u2019s in my own interest to create and return these parameter lists without any delay, but I ask for your understanding if it takes a bit longer due to work or family matters. Once you have received the parameter list (or taken the one from version 2.2.x), you have to replace the existing BSB_LAN_custom_defs.h file with the one sent to you, compile it and flash it again. Now you are ready to access all parameters.","title":"Assemblage"},{"location":"fr/quickstart.html","text":"Quickstart instructions These quickstart instructions are for users who are familiar with installing and configuring software on their computer.

Set this to WLAN if you are using WiFi/WLAN.

If you still have a problem after reading this document as well as the FAQ , please open up a bug report on the project's GitHub page and make sure that you provide us with all the necessary log files and further required details, especially from the Serial Monitor (or SerMo in short). Before doing so, however, make sure that you install the most recent version of BSB-LAN from the master repository (not the release version), even if yours is \"just\" a few days old. Still, a lot could have happned since then :)! Using the Serial Monitor Access the Serial Monitor by going to Tools/Serial Monitor in the Arduino IDE. Set the transmission speed to 115200 at the top right corner of the serial monitor window. Make sure you copy the messages right from the moment your microcontroller boots (indicated by the READY message) until the moment you encounter the problem. Please do not send screenshots, only plain text files. The Serial Monitor in the Arduino IDE currently has a bug that allows you to only copy those parts of the Serial Monitor messages that you can see on the screen. Although this means that copying larger portions of log messages is tedious, you still have to provide the complete log in order to get support. Increasing the size of the Serial Monitor window helps a little. Compiling fails: \"Sketch too big\" Select the Minimal SPIFFS (Large APPS with OTA) partition scheme in the Arduino IDE under Tools/Partition Scheme . If you are using over-the-air updates, you have to flash the software once via USB after changing the partition scheme before OTA updates will work again. No access to web-interface anymore If you have changed the settings in such a way that you cannot access the web-interface anymore, there are two ways to restore the system: If you can flash the device: Configure BSB_LAN_config.h with correct, working settings. Set UseEEPROM to 0 . Flash BSB-LAN onto the microcontroller. You can now access BSB-LAN. Go to \"Settings\" and save the settings. This will store the working settings to the EEPROM. Now edit BSB_LAN_config.h again (!) and set UseEEPROM to 1 and flash BSB-LAN again to the microcontroller. Only now will BSB-LAN read and use the settings from the EEPROM, so you can make further changes in the web-interface. If you cannot flash the device: If you cannot flash the device on site, you can reset BSB-LAN to the last BSB_LAN_config.h setting by connecting two pins before and during booting the microcontroller : ESP32-Olimex: Connect pins 34 and 3V3. ESP32-NodeMCU: Connect pins 21 and 3V3. Arduino Due: Connect pins 31 and 33. If the pins were successfully connected, the built-in LED of the microcontroller will flash slowly for four seconds. Afterwards open the configuration in the web-interface, check all settings in the configuration and save them. This will store the working settings to the EEPROM. Temporary access point on an ESP32-based microcontroller On an ESP32-based microcontroller, BSB-LAN will set up its own wireless access point named BSB-LAN if it cannot connect to any network. In this casee, you can connect to this access point with the password BSB-LPB-PPS-LAN and access BSB-LAN via the IP address http://192.168.4.1 and see if you can fix the configuration this way. Keep in mind that if you have set a passkey or HTTP username and password, these are still required if these details are stored in EEPROM or BSB_LAN_config.h . Category list suddenly so small BSB-LAN needs to detect the heating system's controller to determine the categories to display.

No data even though the adapter's red LED is on Make sure the adapter is connected to CL+/CL- and not to the third (G+) pin: G+ will drive the LED, but it's not a data line. Make sure you have powered on the microcontroller . You may think that the heating system powers the microcontroller because the LED on the BSB-LAN adapter is on, but it doesn't. You need to power it separately. With the adapter for the Olimex microcontrollers: Make sure that the BSB-LAN adapter board sits exactly in the center of the UEXT connector. It will still fit in, if it's shifted one pin left or right, but it won't work. Make sure the RX/TX pins are set/detected correctly. The startup sequence in the Serial Monitor will show you what pins have are used or have been auto-detected. No or unreliable network connection Try powering the microcontroller via USB from a laptop. We have had many cases where power supplies were unreliable despite having sufficient ratings. Look at the Serial Monitor log to check if the microcontroller could acquire an IP address. If not, then your network settings or physical connection may be faulty. No connection to hidden WiFi network possible Yes, that is a known restriction. The only way to do that is to set the BSSID explicitly in BSB_LAN_config.h . Room temperature (or any other parameter) cannot be set Check BSB-LAN's settings and make sure that write access is enabled and set to standard or complete . Web-interface freezes when making new connection BSB-LAN is not a multi-tasking system. This means it can attend to one task at a time. So even if a URL command is aborted (by closing the browser window), BSB-LAN might not detect this and only start serving new requests once the previous one is finished. The Serial Monitor is not showing readable data Make sure the speed is set correctly to 115200 bps. Make sure the correct port is selected.","title":"D\u00e9pannage"},{"location":"fr/using.html","text":"Using BSB-LAN Controlling the heating system via the web-interface As a first step \u2013 or if you just want to turn your heating system on or off \u2013 you can simply open the BSB-LAN web-interface and go to the Settings menu. This will display a list of categories from your heating controller. You can click on each category and will get a list of corresponding parameters. If you see a Set button, it means the parameter can be changed, and clicking on the button will send the new value to the heater. If there is no Set button, the parameter is read-only and there is no way to change the parameter. Using BSB-LAN's URL commands Most of BSB-LAN's functionality can be controlled using URL commands. These are useful or even necessary when connecting BSB-LAN to a home automation system , but also provide access to functions not directly accessible via the web-interface. URL commands are called right after BSB-LAN's hostname and an (optional) passkey.

While a bus speed of a mere 4800 bits per second might sound anachronistic these days, it still provides for a stable and robust transmission protocol that is even today perfectly sufficient when it comes to transmitting short messages of a few dozen bytes over lines sometimes as long as one kilometer. The bus topology also allows you to connect BSB-LAN at any point: At the room unit, at the heating system or anywhere where the bus lines are available. You can even add the two wires for BSB-LAN in an already \"occupied\" slot, and it won't harm the other device (proper installation assumed). On top of the same physical layer, three bus systems, BSB, LPB and PPS, cater for different tasks, and while BSB and LPB should always be preferred if available, PPS nevertheless provides a set of parameters that is usually quite enough for the average user. BSB-LAN runs on any of these busses and swapping between them is just changing a few settings away. The Boiler System Bus (BSB) BSB is the most common bus system in Siemens controllers for the last 10-15 years. It is the successor of the PPS system with which it shares the same physical parameters, but is much more versatile: Instead of just a few dozen parameters, it can access hundreds of parameters and group them into various categories for easier navigation. It is a transaction-based protocol where most messages are being sent from one device to another and the recipient returning some kind of feedback, for example whether the task could be completed or whether it contained invalid data. While BSB is capable of addressing multiple devices on the bus, it is not used in systems with more than one heating device. The heating device always has the ID 0 , the display unit on the heating system has the ID 10 (or 0x0A in hexadecimal) and the standard room unit has the ID 6 . BSB-LAN has the ID 66 or 0x42 in hexadecimal. Room units that \"speak\" BSB are, for example, the QAA55 and the QAA75. The Local Process Bus (LPB) LPB was introduced more or less around the same time as PPS which it complemented in terms of communication with other heating devices: While PPS was used to communicate with the room unit, LPB was used to send commands from one main heating device to one or more auxilliary heating devices, for example in a cascade setup. At that time, most of the information transmitted via LPB was related to the internals of the heating system (such as sensor data or internal setpoint temperatures), whereas the parameters relevant for the user (such as comfort temperature setpoint etc.) were only available via PPS. Nowadays, heating devices that offer both LPB and BSB have the same kind of parameter data available on both bus systems. LPB uses a specific addressing scheme with segments and devices. Each segment from 0 to 15 can contain up to 15 devices (from 1 to 15). When writing these addresses, segment and device are separated by a colon: 00:01 or 04:03 . To convert the segment-based address into the destination ID required for BSB-LAN, the formula is as this: SEGMENT multiplied by 16 plus DEVICE minus one. Example: Device 3 in segment 4 equals to 4 * 16 + 3 - 1 = 66. The main heating unit is by definition 00:01 , so this equals to a destination ID 0. To learn more about the LPB system and how it should be deployed, you may refer to these two documents from the end of the 1990s, one covers the basic system data that covers the conceptualization of an LPB network, and the other one deals with the basic engineering data and provides details about cable lengths and diameters etc. Except for some Weishaut heaters, room units are not connected to the heating system via LPB. Newer models use BSB for this task while older models use either PPS or in some cases also OpenTherm. The Point-to-Point Interface (PPS) The Point-to-Point Interface (PPS deriving from the German term \"Punkt-zu-Punkt Schnittstelle\") is compatible to the other systems on a physical layer, but not in the way message telegrams are being exchanged. While BSB and LPB talk to each other by sending telegrams and acknowledging their receipt respectively, PPS is dominated by the heating unit. The heating unit constantly sends its data to the room unit and tells the room unit when and what kind of information it should send. So it may take up to a few minutes until a value that is set in BSB-LAN is actually requested by the heating system and shown there. It is also a very timing sensitive protocol, therefore long other tasks that BSB-LAN is told to do will lead to a temporary interruption and possible error message on the heating system. However, after a short while, this should be clearing by itself when the two components \"talk\" to each other again. Other than BSB and LPB, changes made in BSB-LAN do not take immediate effect. Changing values, for example like the room temperature comfort setpoint, will be stored internally in BSB-LAN first to be sent out to the heating system once it tells the room unit (i.e. BSB-LAN) to do so. This may take up to a minute or so, so one should not be confused that settings do not show up on the heater immediately, as is the case with BSB and LPB. With PPS, BSB-LAN can run in two modes: either listening passively or as a room unit. In passive mode, BSB-LAN can just listen to the data exchanged between the room unit and the heating device. It is not possible to send one's own data, for the simple fact that it would be overwritten in no time by the same type of data coming from the room unit. In order to send parameter data to the heating system, BSB-LAN mus run in \"room unit\" mode, and this means that any room unit will have to be removed from the heating system. In this case, it is especially important to regularly send a room temperature value to BSB-LAN which in turn will send this value to the heating device. Only if the heater runs solely on outside temperature then this value can be ignored. BSB-LAN stores some values in its non-volatile EEPROM, but some values need to be set anew after a reboot, such as the room temperature setpoint. This is to prevent to store a parameter value that has become invalid but is still sent as it is stored in the EEPROM.

Any further changes can be done also in the web-interface. It may, however, be useful to do the configuration (also) in the configuration file in case one needs to change the microcontroller. Almost all settings exist also in the web-interface and vice versa. On an ESP32-based microcontroller, BSB-LAN will set up its own wireless access point named BSB-LAN if it cannot connect to any network. So even without any further configuration, you can connect to this access point with the password BSB-LPB-PPS-LAN and access BSB-LAN via the IP address http://192.168.4.1 and proceed with the configuration via this way. Keep in mind that if you have set a passkey or HTTP username and password, these are still required if these details are stored in EEPROM or BSB_LAN_config.h . Configuration through `BSB_LAN_config.h`` The configuration file consists of variables that are used in other parts of BSB-LAN. It is therefore important to only change the contents of the variables (i.e. the settings) and not the type of the variables. So if there is for example the setting byte ip_addr[4] = {192,168,178,88}; you must not alter the byte ip_addr[4] = part, only the contents, in this case the comma-separated IP address. Configuration through the web-interface Configuring BSB-LAN through the web-interface is pretty straightforward, as you don't have to deal with variable names but clear descriptions. Initially, only a selected number of configuration options are displayed in the webinterface. To have access to all of them, you have to set the \"extended configuration\" option to \"on\".

As a prerequisite, a MQTT broker (such as mosquitto is needed, either running locally or via making use of a public service. Some home automation systems such as Home Assistant offer the installation of mosquitto as part of their software. In BSB-LAN, you need to make or enable at least the following configurations: Set Logging mode (additionally) to Send to MQTT Broker . Set Log Interval to the time (in seconds) you want the log parameters to be published. Select up to 20 Log Parameters you want to be sent to your home automation system. Set MQTT Usage to plain text Set MQTT Broker Server to the hostname of your MQTT broker (such as the mosquitto server) If your home automation system supports MQTT auto-discovery (as is the case with Home Assistant), you can call URL command /M1 and BSB-LAN will send auto-discovery messages for all available parameters to the MQTT broker and thus to the home automation system. You may have to clean up afterwards or send a removal message for all these parameters using URL command /M0 . Every time a query is made in BSB-LAN or a parameter changes its value through the room unit, the new value will be sent to the MQTT broker, so even changes made outside of BSB-LAN should be updated into the home automation system, which is why the MQTT approach is the recommended way to connect to a home automation system. Examples for querying or setting parameters via MQTT would look like this (using mosquitto): Query the outside temperature (parameter 8700): mosquitto_pub -h my.mosquitto-broker.local -u USER -P PASSWORD -m \"8700\" -t BSB-LAN -d Set the comfort temperature setpoint (parameter 710) to 20 degrees: mosquitto_pub -h my.mosquitto-broker.local -u USER -P PASSWORD -m \"S700=20\" -t BSB-LAN -d Exchanging data via JSON BSB-LAN allows to query and set parameters via JSON structures and also provides numerous information about the parameters and category structures this way. The JSON API is accessd via URL commands and the openapi.yaml file provided in this repository can be used with Swagger to explore its possibilities and functionalitites. Using supported modules for specific home automation systems For some systems, specific modules exist that can be used to access BSB-LAN seamlessly: Home Assistant While the official plugin no longer works, the MQTT approach above works well with Home Assistant. For the details of the implementation, you may also refer to these tutorials: GitHub user @ryann72 wrote detailed instructions for BSB-LAN and HomeAssistant/Mosquitto .

As a prerequisite, a MQTT broker (such as mosquitto is needed, either running locally or via making use of a public service. Some home automation systems such as Home Assistant offer the installation of mosquitto as part of their software. In BSB-LAN, you need to make or enable at least the following configurations: Set Logging mode (additionally) to Send to MQTT Broker . Set Log Interval to the time (in seconds) you want the log parameters to be published. Select up to 20 Log Parameters you want to be sent to your home automation system. Set MQTT Usage to plain text Set MQTT Broker Server to the hostname of your MQTT broker (such as the mosquitto server) If your home automation system supports MQTT auto-discovery (as is the case with Home Assistant), you can call URL command /M1 and BSB-LAN will send auto-discovery messages for all available parameters to the MQTT broker and thus to the home automation system. You may have to clean up afterwards or send a removal message for all these parameters using URL command /M0 . Every time a query is made in BSB-LAN or a parameter changes its value through the room unit, the new value will be sent to the MQTT broker, so even changes made outside of BSB-LAN should be updated into the home automation system, which is why the MQTT approach is the recommended way to connect to a home automation system. Examples for querying or setting parameters via MQTT would look like this (using mosquitto): Query the outside temperature (parameter 8700): mosquitto_pub -h my.mosquitto-broker.local -u USER -P PASSWORD -m \"8700\" -t BSB-LAN -d Set the comfort temperature setpoint (parameter 710) to 20 degrees: mosquitto_pub -h my.mosquitto-broker.local -u USER -P PASSWORD -m \"S700=20\" -t BSB-LAN -d","title":"Exchanging data via MQTT"},{"location":"homeautomation.html#exchanging-data-via-json","text":"BSB-LAN allows to query and set parameters via JSON structures and also provides numerous information about the parameters and category structures this way.

Navigate to the BSB_LAN folder and rename the following files: BSB_LAN_custom_defs.h.default to BSB_LAN_custom_defs.h BSB_LAN_config.h.default to BSB_LAN_config.h . Download and install the Arduino IDE for your system. Connect your microcontroller (ESP32 or Arduino Due) to your computer and start the Arduino IDE. Go to Tools/Board/Board Manager and make sure that the framework for your board is installed (\"esp32 by Espressif Systems\" for ESP32 microcontroller, \"Arduino SAM Boards (32-bits ARM Cortex-M3) by Arduino\" for Arduino Due microcontroller) Again, go to Tools/Board and select your microcontroller: ESP32 Dev Module for the Joy-It ESP32 NodeMCU. Olimex ESP32-EVB for the ESP32-based Olimex EVB . Olimex ESP32-POE-ISO for the ESP32-based Olimex POE ISO Arduino Due (Programming Port) for the Arduino Due. Do not use the Native USB Port here ! Again, go to Tools/Board and select the proper upload speed (460800 for ESP32, 115200 for Arduino Due). For ESP32-based microcontrollers, again, go to Tools/Board and select \"Minimal SPIFFS (Large APPS with OTA)\" for partition scheme ( do not confuse this with the similar \"Minimal\" partition scheme which is different and not working in our case). If you don't set the correct parition scheme, the firmware will not fit into the ESP32! Go to File/Open and navigate to the BSB_LAN folder and double-click on BSB_LAN.ino . The project will open. You may now proceed to configure BSB-LAN. When you are done configuring, go to Sketch/Upload and upload the BSB-LAN software to the microcontroller. Subsequent updates on ESP32-based microcontrollers \"over the air\" (OTA) If you are running BSB-LAN on an ESP32-based microcontroller and have enabled Over-the-Air Updates in the settings , you can perform future updates of BSB-LAN using your browser. To do that, instead of using Sketch/Upload , you need to select Sketch/Export Compiled Binary . This will create a build folder in your BSB-LAN folder in which you will find among others the file BSB_LAN.ino.bin . Now open http://bsb-lan.local:8080 and select and upload that file. Do not interrupt the upload process. You may try to access BSB-LAN from a different browser window to see if the process is completed. Please take note that this only applies to ESP32-based microcontrollers. Arduinos do not support this functionality. Assembling the BSB-LAN adapter You can either get a fully assembled adapter from Frederik (bsb(\u00e4t)code-it.de) or build one on your own (see the folder schematics for the schematics). Once you have the BSB-LAN adapter ready, you just need to plug it into the microcontroller. If you are using an Olimex microcontroller, double-check that the adapter really sits in the center of the connector, because it still fits even if it is moved by one pin row to the left or right. Connecting BSB-LAN to the heating system Once the microcontroller and the BSB-LAN adapter are ready, perform the following steps to connect BSB-LAN to the heating system: Unplug the microcontroller from your computer and turn off your heating system. Locate the BSB/LPB/PPS connectors. You may have to open your heating system for that. Have a look at the list of supported heating systems to get an idea where the pins are located. Do all this at your own risk! Especially take care to prevent electrostatic discharge (ESD) which can destroy both BSB-LAN and the heating controller! Now plug the BSB-LAN adapter onto the microcontroller and connect the + screw connector to the CL+ (BSB), DB (LPB) or A6 (PPS, different connector names are possible) connector, and the - screw connector to the CL- (BSB), MB (LPB) or M (PPS) connector. If there is no empty connector, there is no problem adding the wires for BSB-LAN to an already \"used\" connector, provided the wires are inserted carefully. Now you need to power on the microcontroller. Take note that the heating system does not power the microcontroller, even if the BSB-LAN adapter's LED turns on when you connect it to the heating system. You need to supply power to the microcontroller via its USB port (or via PoE on the Olimex POE-ISO). Make sure to use a stable power supply with at least 2 amperes. Once the microcontroller is powered on, turn on the heating system. The red LED of the BSB-LAN adapter should alight. It should flicker occasionally. Now open your webbrowser and open the IP address of BSB-LAN. If MDNS is enabled, you can directly go to http://bsb-lan.local . Otherwise, you can find the IP address of BSB-LAN either in your router, or you connect the microcontroller to your PC and open the Arduino IDE and go to Tools/Serial Monitor and set the serial monitor speed to 115200. Restart the microcontroller, and the IP address will be displayed upon connecting to the network. Generating the device-specific parameter list Once you access BSB-LAN for the first time, you will see that only very few parameters are shown on the device\u2019s web interface. This is because each model of the Siemens controller built into your heating system supports a different set of parameters. Previously, I provided a list of parameters collected from all different kinds of heating systems, but it turned out that this list was ambiguous or even contained errors that we couldn\u2019t fix reliably. This list is still available in release version 2.2.x of BSB-LAN and can be copied from there if needed. However, it is not advisable to do so because the said ambiguities and errors pose too great a risk of misconfiguring the heating system. Instead, it is recommended to click on the \" Device-specific parameter list \" button in BSB-LAN's menu and send the generated list to Frederik (bsb(\u00e4t)code-it.de). From this file, a parameter list can be generated that fits exactly the controller of your heating system. Unfortunately, this process cannot be automated yet, but at least it has to be done just once. These raw data do not contain any settings or other kinds of personal data, just the parameter structure of the heating system. It\u2019s in my own interest to create and return these parameter lists without any delay, but I ask for your understanding if it takes a bit longer due to work or family matters. Once you have received the parameter list (or taken the one from version 2.2.x), you have to replace the existing BSB_LAN_custom_defs.h file with the one sent to you, compile it and flash it again. Now you are ready to access all parameters.","title":"Installation"},{"location":"install.html#installation","text":"Installing BSB-LAN requires three steps: Installing the Arduino IDE in order to flash the BSB-LAN software onto the microcontroller Assembling the hardware parts Connecting BSB-LAN to the heating system","title":"Installation"},{"location":"install.html#installing-the-arduino-ide-and-flashing-bsb-lan","text":"Download and unpack the current BSB-LAN version from the master repository or use git to clone the repository.

You can find the IP address of BSB-LAN either in your router, or you connect the microcontroller to your PC and open the Arduino IDE and go to Tools/Serial Monitor . Restart the microcontroller, and the IP address will be displayed upon connecting to the network.

This is because each model of the Siemens controller built into your heating system supports a different set of parameters. Previously, I provided a list of parameters collected from all different kinds of heating systems, but it turned out that this list was ambiguous or even contained errors that we couldn\u2019t fix reliably. This list is still available in release version 2.2.x of BSB-LAN and can be copied from there if needed. However, it is not advisable to do so because the said ambiguities and errors pose too great a risk of misconfiguring the heating system. Instead, it is recommended to click on the \" Device-specific parameter list \" button in BSB-LAN's menu and send the generated list to Frederik (bsb(\u00e4t)code-it.de). From this file, a parameter list can be generated that fits exactly the controller of your heating system. Unfortunately, this process cannot be automated yet, but at least it has to be done just once. These raw data do not contain any settings or other kinds of personal data, just the parameter structure of the heating system. It\u2019s in my own interest to create and return these parameter lists without any delay, but I ask for your understanding if it takes a bit longer due to work or family matters.","title":"Why do I only see so few parameters?"},{"location":"supported_heating_systems.html","text":"Supported heating systems BSB-LAN supports heating systems that communicate using either the BSB (Boiler System Bus) , the LPB (Local Process Bus) or the PPS (Punkt-zu-Punkt-Schnittstelle) .

Before doing so, however, make sure that you install the most recent version of BSB-LAN from the master repository (not the release version), even if yours is \"just\" a few days old. Still, a lot could have happned since then :)! Using the Serial Monitor Access the Serial Monitor by going to Tools/Serial Monitor in the Arduino IDE. Set the transmission speed to 115200 at the top right corner of the serial monitor window. Make sure you copy the messages right from the moment your microcontroller boots (indicated by the READY message) until the moment you encounter the problem. Please do not send screenshots, only plain text files. The Serial Monitor in the Arduino IDE currently has a bug that allows you to only copy those parts of the Serial Monitor messages that you can see on the screen. Although this means that copying larger portions of log messages is tedious, you still have to provide the complete log in order to get support. Increasing the size of the Serial Monitor window helps a little. Compiling fails: \"Sketch too big\" Select the Minimal SPIFFS (Large APPS with OTA) partition scheme in the Arduino IDE under Tools/Partition Scheme . If you are using over-the-air updates, you have to flash the software once via USB after changing the partition scheme before OTA updates will work again. No access to web-interface anymore If you have changed the settings in such a way that you cannot access the web-interface anymore, there are two ways to restore the system: If you can flash the device: Configure BSB_LAN_config.h with correct, working settings. Set UseEEPROM to 0 . Flash BSB-LAN onto the microcontroller. You can now access BSB-LAN. Go to \"Settings\" and save the settings. This will store the working settings to the EEPROM. Now edit BSB_LAN_config.h again (!) and set UseEEPROM to 1 and flash BSB-LAN again to the microcontroller. Only now will BSB-LAN read and use the settings from the EEPROM, so you can make further changes in the web-interface. If you cannot flash the device: If you cannot flash the device on site, you can reset BSB-LAN to the last BSB_LAN_config.h setting by connecting two pins before and during booting the microcontroller : ESP32-Olimex: Connect pins 34 and 3V3. ESP32-NodeMCU: Connect pins 21 and 3V3. Arduino Due: Connect pins 31 and 33. If the pins were successfully connected, the built-in LED of the microcontroller will flash slowly for four seconds. Afterwards open the configuration in the web-interface, check all settings in the configuration and save them. This will store the working settings to the EEPROM. Temporary access point on an ESP32-based microcontroller On an ESP32-based microcontroller, BSB-LAN will set up its own wireless access point named BSB-LAN if it cannot connect to any network. In this casee, you can connect to this access point with the password BSB-LPB-PPS-LAN and access BSB-LAN via the IP address http://192.168.4.1 and see if you can fix the configuration this way. Keep in mind that if you have set a passkey or HTTP username and password, these are still required if these details are stored in EEPROM or BSB_LAN_config.h . Category list suddenly so small BSB-LAN needs to detect the heating system's controller to determine the categories to display.

No data even though the adapter's red LED is on Make sure the adapter is connected to CL+/CL- and not to the third (G+) pin: G+ will drive the LED, but it's not a data line. Make sure you have powered on the microcontroller . You may think that the heating system powers the microcontroller because the LED on the BSB-LAN adapter is on, but it doesn't. You need to power it separately. With the adapter for the Olimex microcontrollers: Make sure that the BSB-LAN adapter board sits exactly in the center of the UEXT connector. It will still fit in, if it's shifted one pin left or right, but it won't work. Make sure the RX/TX pins are set/detected correctly. The startup sequence in the Serial Monitor will show you what pins have are used or have been auto-detected. No or unreliable network connection Try powering the microcontroller via USB from a laptop. We have had many cases where power supplies were unreliable despite having sufficient ratings.

BSB-LAN is a software /hardware solution for accessing the \u201cBoiler-System-Bus\u201d (BSB) , the \u201cLocal-Process-Bus (LPB)\u201d and the \u201cPunkt-zu-Punkt-Schnittstelle\u201d (PPS) . The BSB-LAN hardware is available for various ESP32 -based microcontrollers (ESP32 NodeMCU, Olimex EVB, Olimex POE-ISO) as well as for an Arduino Due with Ethernet shield. It allows accessing the heating systems from Atlantic, Br\u00f6tje, Elco and many other manufacturers via LAN/WLAN, provided that they use one of the Siemens controllers listed below. BSB-LAN makes it possible to monitor and control the heating system and log any given values. This project supports almost all parameters available on the heating systems and can be a more comprehensive and cost-effective alternative to the OZW 672, OCI 700 or Remocon Net B. Optional integration into existing smart home systems such as Home Assistant , ioBroker , openHAB , Node-RED , Homebridge , Jeedom , SmartHomeNG , Volksz\u00e4hler , FHEM , HomeMatic , Loxone, IP-Symcon or EDOMI is possible via MQTT , JSON or HTTP access . The adapter can also be used as a standalone logger without LAN or Internet connection when using a microSD card. Temperature and humidity sensors can also be connected and their data can also be logged and analyzed. The option of integrating your own code into the BSB-LAN software also offers a wide range of expansion options. Where and how do I begin? You are an experienced user? Head on to the quickstart instructions . Otherwise (or if you run into problems), please read on! Is my heating system supported by BSB-LAN? Please go to the list of supported heating systems . If you already know that your system is supported, find out more about the BSB-LAN adapter and where to get it. If you already have the adapter, you may want to know how to install the adapter . If you have installed the adapter, you will need to configure BSB-LAN . Once you have everything up and running, find out about how to use BSB-LAN or learn more about the ways to ingetrate BSB-LAN into home automation systems .

In order to connect to your heating system with a microcontroller, you need to have an adapter board that does the necessary logic-level conversion: The adapter is then plugged right onto the microcontroller, either underneath the pins of the ESP32-NodeMCU or onto the UEXT connector of the Olimex: The two different types of ESP32 adapters (Olimex and ESP32-NoceMCU) only vary in the location of their connectors, the other parts of the board are identical. The Arduino Due board contains an EEPROM chip because the Due does not come with on-board EEPROM. Therefore, you can re-use the Arduino Due board on an ESP32 microcontroller (if you connect the correct pins with wires), but you cannot use an adapter for the ESP32 on an Arduino Due. Suitable microcontrollers BSB-LAN can be installed on three different types of microcontrollers: ESP32-Olimex ESP32-NodeMCU (30 pin version only!) and Arduino Due. Olimex produces several kinds of boards: We recommend either the Olimex ESP32-EVB or the Olimex ESP32-POE-ISO . The simple POE version (without the \"ISO\") is not recommended because it does not allow to be connected to PoE Ethernet and USB at the same time. The Arduino Due requires an Ethernet Shield in order to access the local network.

While a bus speed of a mere 4800 bits per second might sound anachronistic these days, it still provides for a stable and robust transmission protocol that is even today perfectly sufficient when it comes to transmitting short messages of a few dozen bytes over lines sometimes as long as one kilometer. The bus topology also allows you to connect BSB-LAN at any point: At the room unit, at the heating system or anywhere where the bus lines are available. You can even add the two wires for BSB-LAN in an already \"occupied\" slot, and it won't harm the other device (proper installation assumed). On top of the same physical layer, three bus systems, BSB, LPB and PPS, cater for different tasks, and while BSB and LPB should always be preferred if available, PPS nevertheless provides a set of parameters that is usually quite enough for the average user. BSB-LAN runs on any of these busses and swapping between them is just changing a few settings away. The Boiler System Bus (BSB) BSB is the most common bus system in Siemens controllers for the last 10-15 years. It is the successor of the PPS system with which it shares the same physical parameters, but is much more versatile: Instead of just a few dozen parameters, it can access hundreds of parameters and group them into various categories for easier navigation. It is a transaction-based protocol where most messages are being sent from one device to another and the recipient returning some kind of feedback, for example whether the task could be completed or whether it contained invalid data. While BSB is capable of addressing multiple devices on the bus, it is not used in systems with more than one heating device. The heating device always has the ID 0 , the display unit on the heating system has the ID 10 (or 0x0A in hexadecimal) and the standard room unit has the ID 6 . BSB-LAN has the ID 66 or 0x42 in hexadecimal. Room units that \"speak\" BSB are, for example, the QAA55 and the QAA75. The Local Process Bus (LPB) LPB was introduced more or less around the same time as PPS which it complemented in terms of communication with other heating devices: While PPS was used to communicate with the room unit, LPB was used to send commands from one main heating device to one or more auxilliary heating devices, for example in a cascade setup. At that time, most of the information transmitted via LPB was related to the internals of the heating system (such as sensor data or internal setpoint temperatures), whereas the parameters relevant for the user (such as comfort temperature setpoint etc.) were only available via PPS. Nowadays, heating devices that offer both LPB and BSB have the same kind of parameter data available on both bus systems. LPB uses a specific addressing scheme with segments and devices. Each segment from 0 to 15 can contain up to 15 devices (from 1 to 15). When writing these addresses, segment and device are separated by a colon: 00:01 or 04:03 . To convert the segment-based address into the destination ID required for BSB-LAN, the formula is as this: SEGMENT multiplied by 16 plus DEVICE minus one. Example: Device 3 in segment 4 equals to 4 * 16 + 3 - 1 = 66. The main heating unit is by definition 00:01 , so this equals to a destination ID 0. To learn more about the LPB system and how it should be deployed, you may refer to these two documents from the end of the 1990s, one covers the basic system data that covers the conceptualization of an LPB network, and the other one deals with the basic engineering data and provides details about cable lengths and diameters etc. Except for some Weishaut heaters, room units are not connected to the heating system via LPB. Newer models use BSB for this task while older models use either PPS or in some cases also OpenTherm. The Point-to-Point Interface (PPS) The Point-to-Point Interface (PPS deriving from the German term \"Punkt-zu-Punkt Schnittstelle\") is compatible to the other systems on a physical layer, but not in the way message telegrams are being exchanged. While BSB and LPB talk to each other by sending telegrams and acknowledging their receipt respectively, PPS is dominated by the heating unit. The heating unit constantly sends its data to the room unit and tells the room unit when and what kind of information it should send. So it may take up to a few minutes until a value that is set in BSB-LAN is actually requested by the heating system and shown there. It is also a very timing sensitive protocol, therefore long other tasks that BSB-LAN is told to do will lead to a temporary interruption and possible error message on the heating system. However, after a short while, this should be clearing by itself when the two components \"talk\" to each other again. Other than BSB and LPB, changes made in BSB-LAN do not take immediate effect. Changing values, for example like the room temperature comfort setpoint, will be stored internally in BSB-LAN first to be sent out to the heating system once it tells the room unit (i.e. BSB-LAN) to do so. This may take up to a minute or so, so one should not be confused that settings do not show up on the heater immediately, as is the case with BSB and LPB. With PPS, BSB-LAN can run in two modes: either listening passively or as a room unit. In passive mode, BSB-LAN can just listen to the data exchanged between the room unit and the heating device. It is not possible to send one's own data, for the simple fact that it would be overwritten in no time by the same type of data coming from the room unit. In order to send parameter data to the heating system, BSB-LAN mus run in \"room unit\" mode, and this means that any room unit will have to be removed from the heating system. In this case, it is especially important to regularly send a room temperature value to BSB-LAN which in turn will send this value to the heating device. Only if the heater runs solely on outside temperature then this value can be ignored. BSB-LAN stores some values in its non-volatile EEPROM, but some values need to be set anew after a reboot, such as the room temperature setpoint. This is to prevent to store a parameter value that has become invalid but is still sent as it is stored in the EEPROM. Room units commonly used with heating systems that support PPS are the QAA50 and the QAA70.","title":"Der BSB/LPB/PPS Bus"},{"location":"de/configure.html","text":"Configuration There are two ways to configure BSB-LAN: Through the configuration file BSB_LAN_config.h Through the web-interface by calling http://bsb-lan.local/C (or the corresponding IP address) For the initial configuration, some settings have to be configured in the configuration file (such as language and network settings). Any further changes can be done also in the web-interface. It may, however, be useful to do the configuration (also) in the configuration file in case one needs to change the microcontroller. Almost all settings exist also in the web-interface and vice versa. On an ESP32-based microcontroller, BSB-LAN will set up its own wireless access point named BSB-LAN if it cannot connect to any network. So even without any further configuration, you can connect to this access point with the password BSB-LPB-PPS-LAN and access BSB-LAN via the IP address http://192.168.4.1 and proceed with the configuration via this way. Keep in mind that if you have set a passkey or HTTP username and password, these are still required if these details are stored in EEPROM or BSB_LAN_config.h . Configuration through `BSB_LAN_config.h`` The configuration file consists of variables that are used in other parts of BSB-LAN. It is therefore important to only change the contents of the variables (i.e. the settings) and not the type of the variables. So if there is for example the setting byte ip_addr[4] = {192,168,178,88}; you must not alter the byte ip_addr[4] = part, only the contents, in this case the comma-separated IP address. Configuration through the web-interface Configuring BSB-LAN through the web-interface is pretty straightforward, as you don't have to deal with variable names but clear descriptions. Initially, only a selected number of configuration options are displayed in the webinterface. To have access to all of them, you have to set the \"extended configuration\" option to \"on\".

To address the default destination, you can do so by using -1 .","title":"Konfiguration"},{"location":"de/homeautomation.html","text":"Connecting BSB-LAN to home automation systems BSB-LAN provides four ways to connect to home automation systems: Exchanging data via MQTT (recommended) Exchanging data via JSON Using supported modules for specific home automation systems Exchanging data via URL commands and screen scraping Exchanging data via MQTT This is the recommended way to connect BSB-LAN to home automation systems because it allows seamless exchange of data. As a prerequisite, a MQTT broker (such as mosquitto is needed, either running locally or via making use of a public service. Some home automation systems such as Home Assistant offer the installation of mosquitto as part of their software. In BSB-LAN, you need to make or enable at least the following configurations: Set Logging mode (additionally) to Send to MQTT Broker . Set Log Interval to the time (in seconds) you want the log parameters to be published. Select up to 20 Log Parameters you want to be sent to your home automation system. Set MQTT Usage to plain text Set MQTT Broker Server to the hostname of your MQTT broker (such as the mosquitto server) If your home automation system supports MQTT auto-discovery (as is the case with Home Assistant), you can call URL command /M1 and BSB-LAN will send auto-discovery messages for all available parameters to the MQTT broker and thus to the home automation system. You may have to clean up afterwards or send a removal message for all these parameters using URL command /M0 . Every time a query is made in BSB-LAN or a parameter changes its value through the room unit, the new value will be sent to the MQTT broker, so even changes made outside of BSB-LAN should be updated into the home automation system, which is why the MQTT approach is the recommended way to connect to a home automation system. Examples for querying or setting parameters via MQTT would look like this (using mosquitto): Query the outside temperature (parameter 8700): mosquitto_pub -h my.mosquitto-broker.local -u USER -P PASSWORD -m \"8700\" -t BSB-LAN -d Set the comfort temperature setpoint (parameter 710) to 20 degrees: mosquitto_pub -h my.mosquitto-broker.local -u USER -P PASSWORD -m \"S700=20\" -t BSB-LAN -d Exchanging data via JSON BSB-LAN allows to query and set parameters via JSON structures and also provides numerous information about the parameters and category structures this way. The JSON API is accessd via URL commands and the openapi.yaml file provided in this repository can be used with Swagger to explore its possibilities and functionalitites. Using supported modules for specific home automation systems For some systems, specific modules exist that can be used to access BSB-LAN seamlessly: Home Assistant While the official plugin no longer works, the MQTT approach above works well with Home Assistant. For the details of the implementation, you may also refer to these tutorials: GitHub user @ryann72 wrote detailed instructions for BSB-LAN and HomeAssistant/Mosquitto . It is also available in French . YouTuber @StoneTime has created two videos (in German) where he shows the installation of BSB-LAN as well as setting it up in Home Assistant . Dankesch\u00f6n!

Bash script GitHub user @khfm has written Bash scripts to query data and display it using gnuplot. Thank you! Exchanging data via URL commands and screen scraping For simpler solutions, using the URL commands to query and set parameters can be used to control BSB-LAN from other systems. Screen scraping is possible since the project tries not to break certain ways of displaying data, so that parsing with regular expressions remains feasible. Nevertheless, for most scenarios one of the other options will probably be preferrable.","title":"Mit dem Smart Home verbinden"},{"location":"de/install.html","text":"Installation Installing BSB-LAN requires three steps: Installing the Arduino IDE in order to flash the BSB-LAN software onto the microcontroller Assembling the hardware parts Connecting BSB-LAN to the heating system Installing the Arduino IDE and flashing BSB-LAN Download and unpack the current BSB-LAN version from the master repository or use git to clone the repository. Navigate to the BSB_LAN folder and rename the following files: BSB_LAN_custom_defs.h.default to BSB_LAN_custom_defs.h BSB_LAN_config.h.default to BSB_LAN_config.h . Download and install the Arduino IDE for your system. Connect your microcontroller (ESP32 or Arduino Due) to your computer and start the Arduino IDE. Go to Tools/Board/Board Manager and make sure that the framework for your board is installed (\"esp32 by Espressif Systems\" for ESP32 microcontroller, \"Arduino SAM Boards (32-bits ARM Cortex-M3) by Arduino\" for Arduino Due microcontroller) Again, go to Tools/Board and select your microcontroller: ESP32 Dev Module for the Joy-It ESP32 NodeMCU. Olimex ESP32-EVB for the ESP32-based Olimex EVB . Olimex ESP32-POE-ISO for the ESP32-based Olimex POE ISO Arduino Due (Programming Port) for the Arduino Due. Do not use the Native USB Port here ! Again, go to Tools/Board and select the proper upload speed (460800 for ESP32, 115200 for Arduino Due). For ESP32-based microcontrollers, again, go to Tools/Board and select \"Minimal SPIFFS (Large APPS with OTA)\" for partition scheme ( do not confuse this with the similar \"Minimal\" partition scheme which is different and not working in our case). If you don't set the correct parition scheme, the firmware will not fit into the ESP32! Go to File/Open and navigate to the BSB_LAN folder and double-click on BSB_LAN.ino . The project will open. You may now proceed to configure BSB-LAN. When you are done configuring, go to Sketch/Upload and upload the BSB-LAN software to the microcontroller. Subsequent updates on ESP32-based microcontrollers \"over the air\" (OTA) If you are running BSB-LAN on an ESP32-based microcontroller and have enabled Over-the-Air Updates in the settings , you can perform future updates of BSB-LAN using your browser. To do that, instead of using Sketch/Upload , you need to select Sketch/Export Compiled Binary . This will create a build folder in your BSB-LAN folder in which you will find among others the file BSB_LAN.ino.bin . Now open http://bsb-lan.local:8080 and select and upload that file. Do not interrupt the upload process. You may try to access BSB-LAN from a different browser window to see if the process is completed. Please take note that this only applies to ESP32-based microcontrollers. Arduinos do not support this functionality. Assembling the BSB-LAN adapter You can either get a fully assembled adapter from Frederik (bsb(\u00e4t)code-it.de) or build one on your own (see the folder schematics for the schematics). Once you have the BSB-LAN adapter ready, you just need to plug it into the microcontroller. If you are using an Olimex microcontroller, double-check that the adapter really sits in the center of the connector, because it still fits even if it is moved by one pin row to the left or right. Connecting BSB-LAN to the heating system Once the microcontroller and the BSB-LAN adapter are ready, perform the following steps to connect BSB-LAN to the heating system: Unplug the microcontroller from your computer and turn off your heating system. Locate the BSB/LPB/PPS connectors. You may have to open your heating system for that. Have a look at the list of supported heating systems to get an idea where the pins are located. Do all this at your own risk! Especially take care to prevent electrostatic discharge (ESD) which can destroy both BSB-LAN and the heating controller! Now plug the BSB-LAN adapter onto the microcontroller and connect the + screw connector to the CL+ (BSB), DB (LPB) or A6 (PPS, different connector names are possible) connector, and the - screw connector to the CL- (BSB), MB (LPB) or M (PPS) connector. If there is no empty connector, there is no problem adding the wires for BSB-LAN to an already \"used\" connector, provided the wires are inserted carefully. Now you need to power on the microcontroller. Take note that the heating system does not power the microcontroller, even if the BSB-LAN adapter's LED turns on when you connect it to the heating system. You need to supply power to the microcontroller via its USB port (or via PoE on the Olimex POE-ISO). Make sure to use a stable power supply with at least 2 amperes. Once the microcontroller is powered on, turn on the heating system. The red LED of the BSB-LAN adapter should alight. It should flicker occasionally. Now open your webbrowser and open the IP address of BSB-LAN. If MDNS is enabled, you can directly go to http://bsb-lan.local . Otherwise, you can find the IP address of BSB-LAN either in your router, or you connect the microcontroller to your PC and open the Arduino IDE and go to Tools/Serial Monitor and set the serial monitor speed to 115200. Restart the microcontroller, and the IP address will be displayed upon connecting to the network. Generating the device-specific parameter list Once you access BSB-LAN for the first time, you will see that only very few parameters are shown on the device\u2019s web interface. This is because each model of the Siemens controller built into your heating system supports a different set of parameters. Previously, I provided a list of parameters collected from all different kinds of heating systems, but it turned out that this list was ambiguous or even contained errors that we couldn\u2019t fix reliably. This list is still available in release version 2.2.x of BSB-LAN and can be copied from there if needed. However, it is not advisable to do so because the said ambiguities and errors pose too great a risk of misconfiguring the heating system. Instead, it is recommended to click on the \" Device-specific parameter list \" button in BSB-LAN's menu and send the generated list to Frederik (bsb(\u00e4t)code-it.de). From this file, a parameter list can be generated that fits exactly the controller of your heating system. Unfortunately, this process cannot be automated yet, but at least it has to be done just once. These raw data do not contain any settings or other kinds of personal data, just the parameter structure of the heating system. It\u2019s in my own interest to create and return these parameter lists without any delay, but I ask for your understanding if it takes a bit longer due to work or family matters. Once you have received the parameter list (or taken the one from version 2.2.x), you have to replace the existing BSB_LAN_custom_defs.h file with the one sent to you, compile it and flash it again. Now you are ready to access all parameters.","title":"Zusammenbauen"},{"location":"de/quickstart.html","text":"Quickstart instructions These quickstart instructions are for users who are familiar with installing and configuring software on their computer.

Set this to WLAN if you are using WiFi/WLAN. If you are not using DHCP, configure the following options according to your network (make sure to use a comma, not a dot for IP addresses!): byte ip_addr[4] = {192,168,178,88}; byte gateway_addr[4] = {192,168,178,1}; byte dns_addr[4] = {192,168,178,1}; byte subnet_addr[4] = {255,255,255,0}; char wifi_ssid[32] = \"Your_Wifi_network_name\"; char wifi_pass[32] = \"Your_WiFi_network_password\"; Now go to Sketch/Upload and upload the BSB-LAN software to the microcontroller.

These controllers are usually manufactured by Siemens, older controllers might still bear the company name \"Landis & Stafea\" or \"Landis & Gyr\". We have compiled a list of working models from various heating system manufacturers who have been confirmed working with BSB-LAN, although there is no 100% guarantee that the manufacturers keep the model name but change the controller to a different system. So always make sure to double-check that the right connectors are available. Here are a few examples from heating controllers and the connectors that are used to connect to BSB-LAN. Some connectors have three pins, some have two pins. If there are three pins, make sure you choose the correct two (CL+ and CL-) as the third von (G+) is to provide background lighting for the room unit. It won't harm BSB-LAN, but it might be misleading because BSB-LAN's LED will be on even though it's not connected to the right pin.

If you still have a problem after reading this document as well as the FAQ , please open up a bug report on the project's GitHub page and make sure that you provide us with all the necessary log files and further required details, especially from the Serial Monitor (or SerMo in short). Before doing so, however, make sure that you install the most recent version of BSB-LAN from the master repository (not the release version), even if yours is \"just\" a few days old. Still, a lot could have happned since then :)! Using the Serial Monitor Access the Serial Monitor by going to Tools/Serial Monitor in the Arduino IDE. Set the transmission speed to 115200 at the top right corner of the serial monitor window. Make sure you copy the messages right from the moment your microcontroller boots (indicated by the READY message) until the moment you encounter the problem. Please do not send screenshots, only plain text files. The Serial Monitor in the Arduino IDE currently has a bug that allows you to only copy those parts of the Serial Monitor messages that you can see on the screen. Although this means that copying larger portions of log messages is tedious, you still have to provide the complete log in order to get support. Increasing the size of the Serial Monitor window helps a little. Compiling fails: \"Sketch too big\" Select the Minimal SPIFFS (Large APPS with OTA) partition scheme in the Arduino IDE under Tools/Partition Scheme . If you are using over-the-air updates, you have to flash the software once via USB after changing the partition scheme before OTA updates will work again. No access to web-interface anymore If you have changed the settings in such a way that you cannot access the web-interface anymore, there are two ways to restore the system: If you can flash the device: Configure BSB_LAN_config.h with correct, working settings. Set UseEEPROM to 0 . Flash BSB-LAN onto the microcontroller. You can now access BSB-LAN. Go to \"Settings\" and save the settings. This will store the working settings to the EEPROM. Now edit BSB_LAN_config.h again (!) and set UseEEPROM to 1 and flash BSB-LAN again to the microcontroller. Only now will BSB-LAN read and use the settings from the EEPROM, so you can make further changes in the web-interface. If you cannot flash the device: If you cannot flash the device on site, you can reset BSB-LAN to the last BSB_LAN_config.h setting by connecting two pins before and during booting the microcontroller : ESP32-Olimex: Connect pins 34 and 3V3. ESP32-NodeMCU: Connect pins 21 and 3V3. Arduino Due: Connect pins 31 and 33. If the pins were successfully connected, the built-in LED of the microcontroller will flash slowly for four seconds. Afterwards open the configuration in the web-interface, check all settings in the configuration and save them. This will store the working settings to the EEPROM. Temporary access point on an ESP32-based microcontroller On an ESP32-based microcontroller, BSB-LAN will set up its own wireless access point named BSB-LAN if it cannot connect to any network. In this casee, you can connect to this access point with the password BSB-LPB-PPS-LAN and access BSB-LAN via the IP address http://192.168.4.1 and see if you can fix the configuration this way. Keep in mind that if you have set a passkey or HTTP username and password, these are still required if these details are stored in EEPROM or BSB_LAN_config.h . Category list suddenly so small BSB-LAN needs to detect the heating system's controller to determine the categories to display. If BSB-LAN is not connected to the controller or the detection otherwise fails, only a few universal categories are displayed. Cannot read any parameters / device family is 0 Wrong bus type (BSB instead of LPB or vice versa). If the red LED of the adapter is not on (and ideally slightly flickering), there is a problem with the wiring between the adapter and the heating system. The red LED will come one once the adapter is connected correctly, even if the BSB-LAN adapter isn't even connected to the microcontroller! No data even though the adapter's red LED is on Make sure the adapter is connected to CL+/CL- and not to the third (G+) pin: G+ will drive the LED, but it's not a data line. Make sure you have powered on the microcontroller . You may think that the heating system powers the microcontroller because the LED on the BSB-LAN adapter is on, but it doesn't. You need to power it separately. With the adapter for the Olimex microcontrollers: Make sure that the BSB-LAN adapter board sits exactly in the center of the UEXT connector. It will still fit in, if it's shifted one pin left or right, but it won't work. Make sure the RX/TX pins are set/detected correctly. The startup sequence in the Serial Monitor will show you what pins have are used or have been auto-detected. No or unreliable network connection Try powering the microcontroller via USB from a laptop. We have had many cases where power supplies were unreliable despite having sufficient ratings. Look at the Serial Monitor log to check if the microcontroller could acquire an IP address. If not, then your network settings or physical connection may be faulty. No connection to hidden WiFi network possible Yes, that is a known restriction. The only way to do that is to set the BSSID explicitly in BSB_LAN_config.h . Room temperature (or any other parameter) cannot be set Check BSB-LAN's settings and make sure that write access is enabled and set to standard or complete . Web-interface freezes when making new connection BSB-LAN is not a multi-tasking system. This means it can attend to one task at a time. So even if a URL command is aborted (by closing the browser window), BSB-LAN might not detect this and only start serving new requests once the previous one is finished. The Serial Monitor is not showing readable data Make sure the speed is set correctly to 115200 bps. Make sure the correct port is selected.","title":"Fehlersuche"},{"location":"de/using.html","text":"Using BSB-LAN Controlling the heating system via the web-interface As a first step \u2013 or if you just want to turn your heating system on or off \u2013 you can simply open the BSB-LAN web-interface and go to the Settings menu. This will display a list of categories from your heating controller. You can click on each category and will get a list of corresponding parameters. If you see a Set button, it means the parameter can be changed, and clicking on the button will send the new value to the heater. If there is no Set button, the parameter is read-only and there is no way to change the parameter. Using BSB-LAN's URL commands Most of BSB-LAN's functionality can be controlled using URL commands. These are useful or even necessary when connecting BSB-LAN to a home automation system , but also provide access to functions not directly accessible via the web-interface.

BSB-LAN is a software /hardware solution for accessing the \u201cBoiler-System-Bus\u201d (BSB) , the \u201cLocal-Process-Bus (LPB)\u201d and the \u201cPunkt-zu-Punkt-Schnittstelle\u201d (PPS) . The BSB-LAN hardware is available for various ESP32 -based microcontrollers (ESP32 NodeMCU, Olimex EVB, Olimex POE-ISO) as well as for an Arduino Due with Ethernet shield. It allows accessing the heating systems from Atlantic, Br\u00f6tje, Elco and many other manufacturers via LAN/WLAN, provided that they use one of the Siemens controllers listed below. BSB-LAN makes it possible to monitor and control the heating system and log any given values. This project supports almost all parameters available on the heating systems and can be a more comprehensive and cost-effective alternative to the OZW 672, OCI 700 or Remocon Net B. Optional integration into existing smart home systems such as Home Assistant , ioBroker , openHAB , Node-RED , Homebridge , Jeedom , SmartHomeNG , Volksz\u00e4hler , FHEM , HomeMatic , Loxone, IP-Symcon or EDOMI is possible via MQTT , JSON or HTTP access . The adapter can also be used as a standalone logger without LAN or Internet connection when using a microSD card. Temperature and humidity sensors can also be connected and their data can also be logged and analyzed. The option of integrating your own code into the BSB-LAN software also offers a wide range of expansion options. Where and how do I begin? You are an experienced user?

In order to connect to your heating system with a microcontroller, you need to have an adapter board that does the necessary logic-level conversion: The adapter is then plugged right onto the microcontroller, either underneath the pins of the ESP32-NodeMCU or onto the UEXT connector of the Olimex: The two different types of ESP32 adapters (Olimex and ESP32-NoceMCU) only vary in the location of their connectors, the other parts of the board are identical. The Arduino Due board contains an EEPROM chip because the Due does not come with on-board EEPROM. Therefore, you can re-use the Arduino Due board on an ESP32 microcontroller (if you connect the correct pins with wires), but you cannot use an adapter for the ESP32 on an Arduino Due. Suitable microcontrollers BSB-LAN can be installed on three different types of microcontrollers: ESP32-Olimex ESP32-NodeMCU (30 pin version only!) and Arduino Due. Olimex produces several kinds of boards: We recommend either the Olimex ESP32-EVB or the Olimex ESP32-POE-ISO . The simple POE version (without the \"ISO\") is not recommended because it does not allow to be connected to PoE Ethernet and USB at the same time.

While a bus speed of a mere 4800 bits per second might sound anachronistic these days, it still provides for a stable and robust transmission protocol that is even today perfectly sufficient when it comes to transmitting short messages of a few dozen bytes over lines sometimes as long as one kilometer. The bus topology also allows you to connect BSB-LAN at any point: At the room unit, at the heating system or anywhere where the bus lines are available. You can even add the two wires for BSB-LAN in an already \"occupied\" slot, and it won't harm the other device (proper installation assumed). On top of the same physical layer, three bus systems, BSB, LPB and PPS, cater for different tasks, and while BSB and LPB should always be preferred if available, PPS nevertheless provides a set of parameters that is usually quite enough for the average user. BSB-LAN runs on any of these busses and swapping between them is just changing a few settings away. The Boiler System Bus (BSB) BSB is the most common bus system in Siemens controllers for the last 10-15 years. It is the successor of the PPS system with which it shares the same physical parameters, but is much more versatile: Instead of just a few dozen parameters, it can access hundreds of parameters and group them into various categories for easier navigation. It is a transaction-based protocol where most messages are being sent from one device to another and the recipient returning some kind of feedback, for example whether the task could be completed or whether it contained invalid data. While BSB is capable of addressing multiple devices on the bus, it is not used in systems with more than one heating device. The heating device always has the ID 0 , the display unit on the heating system has the ID 10 (or 0x0A in hexadecimal) and the standard room unit has the ID 6 . BSB-LAN has the ID 66 or 0x42 in hexadecimal. Room units that \"speak\" BSB are, for example, the QAA55 and the QAA75. The Local Process Bus (LPB) LPB was introduced more or less around the same time as PPS which it complemented in terms of communication with other heating devices: While PPS was used to communicate with the room unit, LPB was used to send commands from one main heating device to one or more auxilliary heating devices, for example in a cascade setup. At that time, most of the information transmitted via LPB was related to the internals of the heating system (such as sensor data or internal setpoint temperatures), whereas the parameters relevant for the user (such as comfort temperature setpoint etc.) were only available via PPS. Nowadays, heating devices that offer both LPB and BSB have the same kind of parameter data available on both bus systems. LPB uses a specific addressing scheme with segments and devices. Each segment from 0 to 15 can contain up to 15 devices (from 1 to 15). When writing these addresses, segment and device are separated by a colon: 00:01 or 04:03 . To convert the segment-based address into the destination ID required for BSB-LAN, the formula is as this: SEGMENT multiplied by 16 plus DEVICE minus one. Example: Device 3 in segment 4 equals to 4 * 16 + 3 - 1 = 66. The main heating unit is by definition 00:01 , so this equals to a destination ID 0. To learn more about the LPB system and how it should be deployed, you may refer to these two documents from the end of the 1990s, one covers the basic system data that covers the conceptualization of an LPB network, and the other one deals with the basic engineering data and provides details about cable lengths and diameters etc. Except for some Weishaut heaters, room units are not connected to the heating system via LPB. Newer models use BSB for this task while older models use either PPS or in some cases also OpenTherm. The Point-to-Point Interface (PPS) The Point-to-Point Interface (PPS deriving from the German term \"Punkt-zu-Punkt Schnittstelle\") is compatible to the other systems on a physical layer, but not in the way message telegrams are being exchanged. While BSB and LPB talk to each other by sending telegrams and acknowledging their receipt respectively, PPS is dominated by the heating unit. The heating unit constantly sends its data to the room unit and tells the room unit when and what kind of information it should send. So it may take up to a few minutes until a value that is set in BSB-LAN is actually requested by the heating system and shown there. It is also a very timing sensitive protocol, therefore long other tasks that BSB-LAN is told to do will lead to a temporary interruption and possible error message on the heating system. However, after a short while, this should be clearing by itself when the two components \"talk\" to each other again. Other than BSB and LPB, changes made in BSB-LAN do not take immediate effect. Changing values, for example like the room temperature comfort setpoint, will be stored internally in BSB-LAN first to be sent out to the heating system once it tells the room unit (i.e. BSB-LAN) to do so. This may take up to a minute or so, so one should not be confused that settings do not show up on the heater immediately, as is the case with BSB and LPB. With PPS, BSB-LAN can run in two modes: either listening passively or as a room unit. In passive mode, BSB-LAN can just listen to the data exchanged between the room unit and the heating device. It is not possible to send one's own data, for the simple fact that it would be overwritten in no time by the same type of data coming from the room unit. In order to send parameter data to the heating system, BSB-LAN mus run in \"room unit\" mode, and this means that any room unit will have to be removed from the heating system. In this case, it is especially important to regularly send a room temperature value to BSB-LAN which in turn will send this value to the heating device. Only if the heater runs solely on outside temperature then this value can be ignored. BSB-LAN stores some values in its non-volatile EEPROM, but some values need to be set anew after a reboot, such as the room temperature setpoint. This is to prevent to store a parameter value that has become invalid but is still sent as it is stored in the EEPROM. Room units commonly used with heating systems that support PPS are the QAA50 and the QAA70.","title":"Les BSB/LPB/PS bus"},{"location":"fr/homeautomation.html","text":"Connecting BSB-LAN to home automation systems BSB-LAN provides four ways to connect to home automation systems: Exchanging data via MQTT (recommended) Exchanging data via JSON Using supported modules for specific home automation systems Exchanging data via URL commands and screen scraping Exchanging data via MQTT This is the recommended way to connect BSB-LAN to home automation systems because it allows seamless exchange of data. As a prerequisite, a MQTT broker (such as mosquitto is needed, either running locally or via making use of a public service. Some home automation systems such as Home Assistant offer the installation of mosquitto as part of their software. In BSB-LAN, you need to make or enable at least the following configurations: Set Logging mode (additionally) to Send to MQTT Broker . Set Log Interval to the time (in seconds) you want the log parameters to be published. Select up to 20 Log Parameters you want to be sent to your home automation system. Set MQTT Usage to plain text Set MQTT Broker Server to the hostname of your MQTT broker (such as the mosquitto server) If your home automation system supports MQTT auto-discovery (as is the case with Home Assistant), you can call URL command /M1 and BSB-LAN will send auto-discovery messages for all available parameters to the MQTT broker and thus to the home automation system. You may have to clean up afterwards or send a removal message for all these parameters using URL command /M0 . Every time a query is made in BSB-LAN or a parameter changes its value through the room unit, the new value will be sent to the MQTT broker, so even changes made outside of BSB-LAN should be updated into the home automation system, which is why the MQTT approach is the recommended way to connect to a home automation system. Examples for querying or setting parameters via MQTT would look like this (using mosquitto): Query the outside temperature (parameter 8700): mosquitto_pub -h my.mosquitto-broker.local -u USER -P PASSWORD -m \"8700\" -t BSB-LAN -d Set the comfort temperature setpoint (parameter 710) to 20 degrees: mosquitto_pub -h my.mosquitto-broker.local -u USER -P PASSWORD -m \"S700=20\" -t BSB-LAN -d Exchanging data via JSON BSB-LAN allows to query and set parameters via JSON structures and also provides numerous information about the parameters and category structures this way. The JSON API is accessd via URL commands and the openapi.yaml file provided in this repository can be used with Swagger to explore its possibilities and functionalitites. Using supported modules for specific home automation systems For some systems, specific modules exist that can be used to access BSB-LAN seamlessly: Home Assistant While the official plugin no longer works, the MQTT approach above works well with Home Assistant. For the details of the implementation, you may also refer to these tutorials: GitHub user @ryann72 wrote detailed instructions for BSB-LAN and HomeAssistant/Mosquitto .

Exchanging data via URL commands and screen scraping For simpler solutions, using the URL commands to query and set parameters can be used to control BSB-LAN from other systems. Screen scraping is possible since the project tries not to break certain ways of displaying data, so that parsing with regular expressions remains feasible. Nevertheless, for most scenarios one of the other options will probably be preferrable.","title":"Connecter \u00e0 la Smart Home"},{"location":"fr/install.html","text":"Installation Installing BSB-LAN requires three steps: Installing the Arduino IDE in order to flash the BSB-LAN software onto the microcontroller Assembling the hardware parts Connecting BSB-LAN to the heating system Installing the Arduino IDE and flashing BSB-LAN Download and unpack the current BSB-LAN version from the master repository or use git to clone the repository.

For ESP32-based microcontrollers, again, go to Tools/Board and select \"Minimal SPIFFS (Large APPS with OTA)\" for partition scheme ( do not confuse this with the similar \"Minimal\" partition scheme which is different and not working in our case). If you don't set the correct parition scheme, the firmware will not fit into the ESP32! Go to File/Open and navigate to the BSB_LAN folder and double-click on BSB_LAN.ino . The project will open. You may now proceed to configure BSB-LAN. When you are done configuring, go to Sketch/Upload and upload the BSB-LAN software to the microcontroller. Subsequent updates on ESP32-based microcontrollers \"over the air\" (OTA) If you are running BSB-LAN on an ESP32-based microcontroller and have enabled Over-the-Air Updates in the settings , you can perform future updates of BSB-LAN using your browser. To do that, instead of using Sketch/Upload , you need to select Sketch/Export Compiled Binary . This will create a build folder in your BSB-LAN folder in which you will find among others the file BSB_LAN.ino.bin . Now open http://bsb-lan.local:8080 and select and upload that file. Do not interrupt the upload process. You may try to access BSB-LAN from a different browser window to see if the process is completed. Please take note that this only applies to ESP32-based microcontrollers. Arduinos do not support this functionality. Assembling the BSB-LAN adapter You can either get a fully assembled adapter from Frederik (bsb(\u00e4t)code-it.de) or build one on your own (see the folder schematics for the schematics). Once you have the BSB-LAN adapter ready, you just need to plug it into the microcontroller. If you are using an Olimex microcontroller, double-check that the adapter really sits in the center of the connector, because it still fits even if it is moved by one pin row to the left or right. Connecting BSB-LAN to the heating system Once the microcontroller and the BSB-LAN adapter are ready, perform the following steps to connect BSB-LAN to the heating system: Unplug the microcontroller from your computer and turn off your heating system. Locate the BSB/LPB/PPS connectors. You may have to open your heating system for that. Have a look at the list of supported heating systems to get an idea where the pins are located. Do all this at your own risk! Especially take care to prevent electrostatic discharge (ESD) which can destroy both BSB-LAN and the heating controller! Now plug the BSB-LAN adapter onto the microcontroller and connect the + screw connector to the CL+ (BSB), DB (LPB) or A6 (PPS, different connector names are possible) connector, and the - screw connector to the CL- (BSB), MB (LPB) or M (PPS) connector. If there is no empty connector, there is no problem adding the wires for BSB-LAN to an already \"used\" connector, provided the wires are inserted carefully. Now you need to power on the microcontroller. Take note that the heating system does not power the microcontroller, even if the BSB-LAN adapter's LED turns on when you connect it to the heating system. You need to supply power to the microcontroller via its USB port (or via PoE on the Olimex POE-ISO). Make sure to use a stable power supply with at least 2 amperes. Once the microcontroller is powered on, turn on the heating system. The red LED of the BSB-LAN adapter should alight. It should flicker occasionally. Now open your webbrowser and open the IP address of BSB-LAN. If MDNS is enabled, you can directly go to http://bsb-lan.local . Otherwise, you can find the IP address of BSB-LAN either in your router, or you connect the microcontroller to your PC and open the Arduino IDE and go to Tools/Serial Monitor and set the serial monitor speed to 115200. Restart the microcontroller, and the IP address will be displayed upon connecting to the network. Generating the device-specific parameter list Once you access BSB-LAN for the first time, you will see that only very few parameters are shown on the device\u2019s web interface. This is because each model of the Siemens controller built into your heating system supports a different set of parameters. Previously, I provided a list of parameters collected from all different kinds of heating systems, but it turned out that this list was ambiguous or even contained errors that we couldn\u2019t fix reliably. This list is still available in release version 2.2.x of BSB-LAN and can be copied from there if needed. However, it is not advisable to do so because the said ambiguities and errors pose too great a risk of misconfiguring the heating system. Instead, it is recommended to click on the \" Device-specific parameter list \" button in BSB-LAN's menu and send the generated list to Frederik (bsb(\u00e4t)code-it.de). From this file, a parameter list can be generated that fits exactly the controller of your heating system. Unfortunately, this process cannot be automated yet, but at least it has to be done just once. These raw data do not contain any settings or other kinds of personal data, just the parameter structure of the heating system. It\u2019s in my own interest to create and return these parameter lists without any delay, but I ask for your understanding if it takes a bit longer due to work or family matters. Once you have received the parameter list (or taken the one from version 2.2.x), you have to replace the existing BSB_LAN_custom_defs.h file with the one sent to you, compile it and flash it again. Now you are ready to access all parameters.","title":"Assemblage"},{"location":"fr/quickstart.html","text":"Quickstart instructions These quickstart instructions are for users who are familiar with installing and configuring software on their computer.

Now plug the BSB-LAN adapter onto the microcontroller and connect the + screw connector to the CL+ (BSB), DB (LPB) or A6 (PPS, different connector names are possible) connector, and the - screw connector to the CL- (BSB), MB (LPB) or M (PPS) connector. Power on the microcontroller via the USB port or via PoE (Olimex POE-ISO only). Then power on the heating system. The red LED of the BSB-LAN adapter should turn on. It should flicker occasionally. Now open your webbrowser and open the IP address of BSB-LAN. If MDNS is enabled, you can directly go to http://bsb-lan.local . You can find the IP address of BSB-LAN either in your router, or you connect the microcontroller to your PC and open the Arduino IDE and go to Tools/Serial Monitor . Restart the microcontroller, and the IP address will be displayed upon connecting to the network. Done :-) It's not working! Please make sure you check every entry in the Troubleshooting-Section first before getting in touch with us! Why do I only see so few parameters? Once you access BSB-LAN for the first time, you will see that only very few parameters are shown on the device\u2019s web interface. This is because each model of the Siemens controller built into your heating system supports a different set of parameters. Previously, I provided a list of parameters collected from all different kinds of heating systems, but it turned out that this list was ambiguous or even contained errors that we couldn\u2019t fix reliably. This list is still available in release version 2.2.x of BSB-LAN and can be copied from there if needed. However, it is not advisable to do so because the said ambiguities and errors pose too great a risk of misconfiguring the heating system. Instead, it is recommended to click on the \" Device-specific parameter list \" button in BSB-LAN's menu and send the generated list to Frederik (bsb(\u00e4t)code-it.de). From this file, a parameter list can be generated that fits exactly the controller of your heating system. Unfortunately, this process cannot be automated yet, but at least it has to be done just once. These raw data do not contain any settings or other kinds of personal data, just the parameter structure of the heating system. It\u2019s in my own interest to create and return these parameter lists without any delay, but I ask for your understanding if it takes a bit longer due to work or family matters.","title":"D\u00e9marrage rapide"},{"location":"fr/supported_heating_systems.html","text":"Supported heating systems BSB-LAN supports heating systems that communicate using either the BSB (Boiler System Bus) , the LPB (Local Process Bus) or the PPS (Punkt-zu-Punkt-Schnittstelle) . These controllers are usually manufactured by Siemens, older controllers might still bear the company name \"Landis & Stafea\" or \"Landis & Gyr\". We have compiled a list of working models from various heating system manufacturers who have been confirmed working with BSB-LAN, although there is no 100% guarantee that the manufacturers keep the model name but change the controller to a different system. So always make sure to double-check that the right connectors are available. Here are a few examples from heating controllers and the connectors that are used to connect to BSB-LAN. Some connectors have three pins, some have two pins. If there are three pins, make sure you choose the correct two (CL+ and CL-) as the third von (G+) is to provide background lighting for the room unit. It won't harm BSB-LAN, but it might be misleading because BSB-LAN's LED will be on even though it's not connected to the right pin.

If you still have a problem after reading this document as well as the FAQ , please open up a bug report on the project's GitHub page and make sure that you provide us with all the necessary log files and further required details, especially from the Serial Monitor (or SerMo in short). Before doing so, however, make sure that you install the most recent version of BSB-LAN from the master repository (not the release version), even if yours is \"just\" a few days old. Still, a lot could have happned since then :)! Using the Serial Monitor Access the Serial Monitor by going to Tools/Serial Monitor in the Arduino IDE. Set the transmission speed to 115200 at the top right corner of the serial monitor window. Make sure you copy the messages right from the moment your microcontroller boots (indicated by the READY message) until the moment you encounter the problem. Please do not send screenshots, only plain text files. The Serial Monitor in the Arduino IDE currently has a bug that allows you to only copy those parts of the Serial Monitor messages that you can see on the screen. Although this means that copying larger portions of log messages is tedious, you still have to provide the complete log in order to get support. Increasing the size of the Serial Monitor window helps a little. Compiling fails: \"Sketch too big\" Select the Minimal SPIFFS (Large APPS with OTA) partition scheme in the Arduino IDE under Tools/Partition Scheme . If you are using over-the-air updates, you have to flash the software once via USB after changing the partition scheme before OTA updates will work again. No access to web-interface anymore If you have changed the settings in such a way that you cannot access the web-interface anymore, there are two ways to restore the system: If you can flash the device: Configure BSB_LAN_config.h with correct, working settings. Set UseEEPROM to 0 . Flash BSB-LAN onto the microcontroller. You can now access BSB-LAN. Go to \"Settings\" and save the settings. This will store the working settings to the EEPROM. Now edit BSB_LAN_config.h again (!) and set UseEEPROM to 1 and flash BSB-LAN again to the microcontroller. Only now will BSB-LAN read and use the settings from the EEPROM, so you can make further changes in the web-interface. If you cannot flash the device: If you cannot flash the device on site, you can reset BSB-LAN to the last BSB_LAN_config.h setting by connecting two pins before and during booting the microcontroller : ESP32-Olimex: Connect pins 34 and 3V3. ESP32-NodeMCU: Connect pins 21 and 3V3. Arduino Due: Connect pins 31 and 33. If the pins were successfully connected, the built-in LED of the microcontroller will flash slowly for four seconds. Afterwards open the configuration in the web-interface, check all settings in the configuration and save them. This will store the working settings to the EEPROM. Temporary access point on an ESP32-based microcontroller On an ESP32-based microcontroller, BSB-LAN will set up its own wireless access point named BSB-LAN if it cannot connect to any network. In this casee, you can connect to this access point with the password BSB-LPB-PPS-LAN and access BSB-LAN via the IP address http://192.168.4.1 and see if you can fix the configuration this way. Keep in mind that if you have set a passkey or HTTP username and password, these are still required if these details are stored in EEPROM or BSB_LAN_config.h . Category list suddenly so small BSB-LAN needs to detect the heating system's controller to determine the categories to display. If BSB-LAN is not connected to the controller or the detection otherwise fails, only a few universal categories are displayed. Cannot read any parameters / device family is 0 Wrong bus type (BSB instead of LPB or vice versa). If the red LED of the adapter is not on (and ideally slightly flickering), there is a problem with the wiring between the adapter and the heating system. The red LED will come one once the adapter is connected correctly, even if the BSB-LAN adapter isn't even connected to the microcontroller! No data even though the adapter's red LED is on Make sure the adapter is connected to CL+/CL- and not to the third (G+) pin: G+ will drive the LED, but it's not a data line. Make sure you have powered on the microcontroller . You may think that the heating system powers the microcontroller because the LED on the BSB-LAN adapter is on, but it doesn't. You need to power it separately. With the adapter for the Olimex microcontrollers: Make sure that the BSB-LAN adapter board sits exactly in the center of the UEXT connector. It will still fit in, if it's shifted one pin left or right, but it won't work. Make sure the RX/TX pins are set/detected correctly. The startup sequence in the Serial Monitor will show you what pins have are used or have been auto-detected. No or unreliable network connection Try powering the microcontroller via USB from a laptop. We have had many cases where power supplies were unreliable despite having sufficient ratings. Look at the Serial Monitor log to check if the microcontroller could acquire an IP address. If not, then your network settings or physical connection may be faulty. No connection to hidden WiFi network possible Yes, that is a known restriction. The only way to do that is to set the BSSID explicitly in BSB_LAN_config.h . Room temperature (or any other parameter) cannot be set Check BSB-LAN's settings and make sure that write access is enabled and set to standard or complete . Web-interface freezes when making new connection BSB-LAN is not a multi-tasking system. This means it can attend to one task at a time. So even if a URL command is aborted (by closing the browser window), BSB-LAN might not detect this and only start serving new requests once the previous one is finished. The Serial Monitor is not showing readable data Make sure the speed is set correctly to 115200 bps. Make sure the correct port is selected.","title":"D\u00e9pannage"},{"location":"fr/using.html","text":"Using BSB-LAN Controlling the heating system via the web-interface As a first step \u2013 or if you just want to turn your heating system on or off \u2013 you can simply open the BSB-LAN web-interface and go to the Settings menu. This will display a list of categories from your heating controller. You can click on each category and will get a list of corresponding parameters. If you see a Set button, it means the parameter can be changed, and clicking on the button will send the new value to the heater. If there is no Set button, the parameter is read-only and there is no way to change the parameter. Using BSB-LAN's URL commands Most of BSB-LAN's functionality can be controlled using URL commands. These are useful or even necessary when connecting BSB-LAN to a home automation system , but also provide access to functions not directly accessible via the web-interface. URL commands are called right after BSB-LAN's hostname and an (optional) passkey.
