Remeha Tzerra Ace - setBoilerTemperature always at 10 °C about esphome-opentherm HOT 4 CLOSED

Perfect, that was the solution.
Many thanks! Now it is working 👍

Hi Jan,
If the heating is off (seems like your room temperature is 21.7c), the target temp is 10c, if you turn on the heating and set the target temp to 24c or so, the target temp should go to 50c. The target temp is 10c when no heat is required, so in this case it's correct.
If the temperature is still not set, you can have a look at this table, see if all required parameters are supported for your boiler:

Yes, maybe that is the problem, but i don't know how to set the room temperature. Is it possible to define the room temperature via the esp opentherm shield? I want to replaced my eTwist-thermostat with the esp opentherm shield for controlling everything via HA, but i have only climate.hot_water, climate.heating_water and the pid.pid_climate_controller controls in HA for setting temperatures.

The controls in HA are set currently to the following values:

The log shows continously the following:

Thanks.

Aha, in line 82 of opentherm.yaml, you need to replace sensor.temperature_sensor with the temperature sensor from home assistant that you want to use as the temperature sensor. So in my case I have an esp temperature sensor in my livingroom with the name sensor.livingroom_temperature_sensor and I replaced that in line 82. If it works you should see the temperature in the middle of the PID climate controller thermostat card.
