read timeout when trying to read different parameters

[pauldtc]

Hello,

first of all thank you for your great work.

I'm struggling though to make ebusd read different parameters such as "z1_heat_request".Everytime i issue a request via "ebusctl read -m 0 -c energymgr z1_heat_request" -> "ERR: read timeout" is returned. My current setup involves a direct serial connection from a PC to eBUS Adapter v5 from John.

Here is my current config:

EBUSD_OPTS="--configpath=/etc/ebusd -d ens:/dev/ttyACM0 --mqttport=1883 --mqtthost=******** --mqttuser ***** --mqttpass ******** --mqttjson --mqttint=/etc/ebusd/mqtt-hassio.cfg --mqtttopic=ebusd/%circuit/%name --enablehex --accesslevel=*"

Ebusctl returns the following:

version: ebusd 23.3.23.3
update check: version 24.1 available, device firmware 1[4a1b] available
device: /dev/ttyACM0, serial high speed, enhanced, firmware 1.1[4a08].1[4a08]

This is what i found from the logs:

I don't know if this problem is related to ebusd, my ebus adapter or my boiler, i'm stuck and any pointers would be really appreciated.

Kind Regards.

Hi pauldtc,
from your ebusctl info command i gather you dont' have the "stand-alone" energy manager, your config should be composed by the boiler, the wifi gateway and the remote control. In the CSV try to map all the lines to the boiler address:

eg. change this:

r,energymgr,z1_heat_request,Z1 Heating Request,,18,2000,0191,,s,IGN:1,,,,,s,onoff

to this

r,energymgr,z1_heat_request,Z1 Heating Request,,3c,2000,0191,,s,IGN:1,,,,,s,onoff

[pauldtc]

Hello,

thank you for your quick reply.

I made the change to z1_heat_request and this is what i get:

ebusctl read -m 0 -c energymgr z1_heat_request
ERR: invalid position in decode

The boiler is a Ariston Alteas One with builtin wifi and 2 Ariston Cube thermostats ( Z1 + Z2 ) wired in parallel on the same bus.

Kind Regards.

OK, it seems the boiler doesn't answer to requests.

313c2000020191 / 0100

means that 3c address is not able to answer (number of parameters reported back count byte =00)

try dumping the most recent messages received by the adapter

ebusctl grab result all > message_dump.txt

and post it here, I need to see what's traveling on the bus

[pauldtc]

message_dump.txt
I've attached the file.

Thanks !

[pauldtc]

I also manually ran the read_all.sh script to poll all items in CSV and also raised the temperature from the thermostat to trigger heating. Now i have more values from "ebusctl grab result all", please see the dump attached.
message_dump2.txt

[wrongisthenewright]

ok, it seems that in your case many parameters are not transmitted on the bus, probably because the boiler and the thermostats don't need to exchange many info.

For the heat request stauts you can use the data broadcasted by these lines:

37fe200f0401910000 = 10
37fe200f0402910000 = 10

using these "ad hoc" CSV lines

b,energymgr,z1_heat_request,Heating Request,37,fe,200f,0191,z1_heat_request,s,BCD,0=off;1=on
b,energymgr,z2_heat_request,Heating Request,37,fe,200f,0291,z2_heat_request,s,BCD,0=off;1=on

but other parameters seems to be missing from the bus.

From what I see from the message dump something (not much) can be gathered by parsing broadcasted messages but it needs a great effort to adapt the file, and not having the device It's really difficult to do debugging.

If you badly need some parameter let me know that I'll look into it.

[pauldtc]

Changed the CSV file as recommended did the trick and i now have status on / off in HA,
I'm looking to get basic functionality out of this as the Ariston app is really slow and unreliable.

Would it be possible to also write a few parameters like Z1 / Z2 Heating Setpoint and DHW temperature ?

Thanks alot for your help, really appreciate it.

[wrongisthenewright]

Would it be possible to also write a few parameters like Z1 / Z2 Heating Setpoint and DHW temperature ?

For z1/z2 Setpoints (Day/Night temps) have you tried with 3c as slave address?Like these:

r,energymgr,z1_day_temp,Z1 Day Temp,,3c,2000,6271,,s,IGN:1,,,,,,SIN,10,°C
b,energymgr,z1_day_temp,Z1 Day Temp,,fe,200f,6271,,m,SIN,10,°C
w,energymgr,z1_day_temp,Z1 Day Temp,,fe,2020,6271,,s,SIN,10,°C
r,energymgr,z1_night_temp,Z1 Night Temp,,18,2000,6371,,s,IGN:1,,,,,,SIN,10,°C
w,energymgr,z1_night_temp,Z1 Night Temp,,fe,2020,6371,,s,SIN,10,°C
b,energymgr,z1_night_temp,Z1 Night Temp,,fe,200f,6371,,m,SIN,10,°C
r,energymgr,z2_day_temp,Z2 Day Temp,,3c,2000,6272,,s,IGN:1,,,,,,SIN,10,°C
b,energymgr,z2_day_temp,Z2 Day Temp,,fe,200f,6272,,m,SIN,10,°C

b,energymgr,z2_night_temp,Z2 Night Temp,,fe,200f,6372,,s,SIN,10,°C
w,energymgr,z2_night_temp,Z2 Night Temp,,fe,2020,6372,,s,SIN,10,°C

for DHW:

r,energymgr,dhw_comfort_temp,DHW Comfort Temp,,3c,2000,6126,,s,SIN,10,°C

[pauldtc]

Hi @wrongisthenewright,

tried it and same error unfortunately:

ebusctl read -m 0 -d 3c -c energymgr dhw_comfort_temp
ERR: invalid position in decode

ebusctl read -m 0 -d 3c -c energymgr z1_day_temp
ERR: invalid position in decode

This is what i've found with ebusctl grab result:
313c2000026271 / 0100 = 1
313c2000026126 / 0100 = 1

Thanks !

[wrongisthenewright]

You can try to leave these lines and change the setpoints from the Cube then see what happens...

[wrongisthenewright]

also: try to look at Ysard repo (https://github.com/ysard/ebusd_configuration_chaffoteaux_bridgenet) he has a configuration similar to your (boiler only, in his case even without Cube/remote thermostat).

Try his CSV, doesn' cost that much...
