There are only a few DATA-IDs mandatory, for a boiler these are: STATUS, SECONDARY_CONFIGURATION, RELATIVE_MODULATION_LEVEL, BOILER_WATER_TEMP, CONTROL_SETPOINT_CH and MAX_MODULATION_LEVEL. For a HVAC I think this suggests that HVAC_STATUS will be mandatory too. So all others are optional.

Just try all OpenTherm::READ_DATA_ID's and test with OpenTherm::error() the response. If the response is OpenTherm::ERROR_CODES::UNKNOWN_DATA_ID your HVAC does not support the DATA-ID.

I added an example, OpenTherm_Show_DATA-IDs,ino, that tries all READ_DATA_IDs and shows the resulting response. The example can also be used to understand the meaning of the flags better. Finally it shows the right units (if any). I hope it will help you!

got it, my arduino IDe was old :-( but we need to install some extra libs, like the pubsub etc, there are a lot of them available:-)
My knowledge is also not that good yet :-)
Thanks
