Remeha Tzerra Ace - setBoilerTemperature always at 10 °C #32

Closed jfranken2 closed 1 year ago

jfranken2 commented 2 years ago

Hello,

first i want to thank you for this great project. Realy good work! I'm trying to use the opentherm master shield with a wemos d1 mini from diyless.com with a remeha tzerra ace boiler.

The hot water control and nearly all sensor values in HA are working fine, except the heating target temperature is always set to 10°C and can't be modified. I don't know why the PID_OUTPUT value is always 0.0.

Here is the log of the wemos d1:

Is there something i forgot to configure, or to modify in the code, or any other ideas? Thank you. Regards Jan

ShurikenGitHub commented 1 year ago

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: https://otgw.tclcode.com/matrix.cgi#boilers

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: image

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.

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