Implementation on its way :+1:

HB: Slave configuration flag8 bit

Would this make sense if implemented using binary sensors? Especially DHW config is a tricky one, since I'd have to name this differently like dhw_storage_tank so true means that there is a storage tank and false means it's instantaneous or not-specified.

I've pushed a branch with the new sensors. Can you give them a try and keep me posted if they work as expected?

I will try to try as soon as possible, could you add output (for PID ESPHOME), unfortunately I can't add it.

[khenderick]

If another component controls outputs, you can use a Template Output and use that to translate writes to that output into calls to the OpenTherm component.

works otc_active.

unfortunately my boiler does not support: dhw_2_temperature: name: "DHW 2 temperature" exhaust_temperature: name: "exhaust temperature" burner_starts: name: "burner starts" burner_ops_hours: name: "burner operation hours" ch_pump_starts: name: "CH pump starts" ch_pump_ops_hours: name: "CH pump operation hours" dhw_pump_valve_starts: name: "DHW pump/valve starts" dhw_pump_valve_ops_hours: name: "DHW pump/valve operation hours" dhw_burner_starts: name: "DHW burner starts" dhw_burner_ops_hours: name: "DHW burner operation hours"

Thanks for the update. I'll assume the other ones will work as well :+1:. I hope to implement the slave configuration bits somewhere today.

[khenderick]

Binary sensors to read out the slave/boiler configuration are also added and everything is merged to main. I'm going to close this ticket, as all requested sensors have been implemented.
