MyHomePlugin

Legrand (BTicino) MyHome plugin for homebridge: https://github.com/nfarina/homebridge

Legrand MyHome (http://www.homesystems-legrandgroup.com/BtHomeSystems/home.action) is an Home Automation solution that can manage:

• lighting (standard on/off/dimmed lights)
• thermoregulation
• curtains, doors
• security systems

With this plugin, the support of a IP gateway installed in your plant and a configuration of all installed systems (MyHome does not support the autodiscovery of the system) you can control it. You need to disable the OpenWebNet password-based authentication from the IP of the device that runs homebridge (ie. Raspberry) or set the auhentication to HMAC; HMAC authentication is supported by all recent IP gateways or older one with updated firmware (eg. F454 with v2 firmware).

Installation (TBD)

Install plugin with npm install -g homebridge-myhome Add platform within config.json of you homebridge instance:

{
    "platforms": [{
        "platform": "MyHome Gateway",
        "ipaddress": "192.168.1.1",
        "password": "12345",
        "discovery": false,
        "devices": [
                /*Static list of devices*/
            ]
        }], 
    "bridge": {
        "username": "CC:22:3D:E3:CE:31", 
        "name": "MyHome HomeBridge Adapter",

        "port": 51826
    },

Restart homebridge Enjoy!

Installation

Run as root:

npm -g install homebridge-myhome-tng

Create your config.json file starting from the template (sample-config.json) and then:

homebridge -U .

Configuration

Only the platforms section of the config.json file should be edited, the pair code and the port in bridge section can be ignored in most of the cases. A little sample:

{
    "platforms": [{
        "platform": "LegrandMyHome",
        "ipaddress": "192.168.157.207",
        "port": 20000,
        "ownpassword": "12345",
        "discovery": false,
        "devices": [{
            "accessory": "MHRelay",
            "name": "Bathroom Light",
            "address": "0/1/5"
            },{
            "accessory": "MHRelay",
            "name": "Night hallway Light",
            "address": "0/1/1"
            },{
            "accessory": "MHRelay",
            "name": "Office",
            "address": "0/1/4"
            },{
            "accessory": "MHDimmer",
            "name": "Master bedroom Central",
            "address": "0/1/2"
            },{
            "accessory": "MHThermostat",
            "name": "Living Room Thermostat",
            "address": "21"
            },{
            "accessory": "MHThermostatExternal",
            "name": "External Thermo Sensor",
            "address": "1"
            }]
        }],
    "bridge": {
        "username": "CC:22:3D:E3:CE:31", 
        "name": "MyHome HomeBridge Adapter", 
        "pin": "342-52-220", 
        "port": 51827
    },

}

The first part of the config file contains details about the MyHome Gateway used to interface the IP network with the plant:

    "platforms": [{
        "platform": "LegrandMyHome",
        "ipaddress": "192.168.157.207",
        "port": 20000,
        "ownpassword": "12345",
        "discovery": false,
        "devices": [{

You need to change:

• ipaddress: put the IP address or name of the MyHome Gateway (eg. F454 or MH201, I'm not so updated about all gateways that BTicino-Legrand releases after 2015); the IP should be static but in the future I can implement a UPNP dicovery because all gateways supports that method
• port: should be 20000 and keep this value
• ownpassword: the OpenWebNet password, default is 12345 but everyone will suggest to you to change it with another password (4 to 9 digits), but you will keep the default one, I know...
• discovery: boolean value, not supported but in the future allows the gateway to discover the plant and detect most of devices
• devices: list of installed devices

The devices section contains the list of devices that will be managed. All devices contains three standard properties:

• accessory: the technical name of the device, should be one of the names listed in this document
• name: mnemonic name, will be displayed by iOS HomeKit application
• address: the MyHome address, usually in B/A/PL format for lights and curtaints or single/double digits for other devices. B stands for BUS (usually 0), A and PL is the name of the addressing object used by BTicino and stands for Ambient and Light Point (Punto Luce in the original italian version)

Supported devices

• MHRelay: Standard (Lighting) Relay (eg. F411), address is B/A/PL (eg. 0/1/10)

  • this device supports the definition of a custom frame for on and off command, so you can specify frame_on and/or frame_off:

        {
        "accessory": "MHRelay",
        "name": "Bathroom Light",
        "address": "0/1/5",
        "frame_on": "*1*1*14##",
        "frame_off": "*1*0*14##"
        }
    

    to use a Group, CEN, CEN+ or other command to turn on and off that load, using the address load for the status monitor. Remember that HomeKit will think that the load has changed the status after the command even if is not true.

• MHScene: Scene (F420) or IRBlaster, address is N, Scene is scenario number (thanks to dendeps) - NOT TESTED

• MHDimmer: Lighting Dimmer (eg. F427, F413N), address is B/A/PL (eg. 0/1/10)

• MHThermostat: Standard Thermostat controlled by a 99-Zones Central Station (code 3550), address is the Zone Identifier (1-99)

• MHExternalThermometer: External Probe controlled by a 99-Zones Central Station (code 3550), address is the Zone Identifier (1-9)

• MHOutlet: Standard (not-Lighting) Relay, address is B/A/PL (eg. 0/1/10). See MHRelay for custom frame support

• MHBlind: Standard Automation Relay (eg. F411, I need to check the F401), address is B/A/PL (eg. 0/1/10)

  • this device defines another property called "time" that defines the configured "stop time" in seconds; using this property the driver can evaluate the current position of the blind

• MHBlindAdvanced: Advanced version of standard Blind (eg. F401 that manages internally the current position), address is B/A/PL (eg. 0/1/10)

• MHContactSensor: Dry Contact sensor (eg. 3477 or some burgalarm sensors), address range is 1-201

• MHPowerMeter: (WILL BE SUPPORTED)

• MHAlarm: (WILL BE SUPPORTED)

Tested devices

• F454v1 and MH201 as IP Gateway
• F411/2 as MHRelay, MHOutlet and MHCurtain
• F401 as MHBlindAdvanced
• F416U1 as MHDimmer
• 3455 as MHExternalThermometer
• 3477 as MHContactSensor

Known Bug List

• Groups are not managed

TODOS

• Reconnection and infinite retry
• Semi-auto discovery and/or read a plant configuration from MyHomeSuite configuration file
• Re-order the code
• IP Gateway discovery
• Group and General Command support
