Configuration file for sensoHOME VRT 380 Thermostat

[rRobbieIT]

Hello,

I have a thermostat Vaillant VRT 380 and I could not find any configuration file for it.

The string from ebusctl info is the following:
address 15: slave #2, scanned "MF=Vaillant;ID=CTLV0;SW=0312;HW=9103"

I have tried to rename some "similar" files (looking at their model and name), but the fields do not match and I get a series of ERR.

Any suggestion is welcome, although to reverse engineer the protocol is probably out of my reach.

Thank You
RP

Sorry to answer to my own message, I want to share my findings hoping they could be useful to someone else.

I managed to make the thermostat works, although only with very basic functionality:

• I used the configuration file 15.700.csv renamed to 15.ctlv0.csv
• Using a quick python script I could iterate within all the commands in the csv file, to find the ones which were returning something meaningful. All in all I am only using z1ActualRoomTempDesired and z1RoomTemp.
• I configured ebusd and MQTT with docker
• I subscribed OpenHAB to the associated MQTT topics as follows:
