Hi all,
I in our house a ventilation heater from the company Zimmermann, brand name “Proxon”. I have managed to read their values via Modbus and partially set values. For example, I can already turn on and off the auxiliary heating fans via Home Assistant.
Where I still have a hard time is to set temperatures for a single room. There, the Proxon works somewhat strangely following its design principle.
Only the target temperatures are still a bit of a headache for me. These are calculated with offset values from a central temperature.
So for example my main control is in the living room. This gives a general basic temperature for the whole house. Let’s say 20 °C. In each room there is also a secondary control. I can adjust the temperature in the respective room, but only within a limited range. Internally, this secondary control then reports an offset value of say -3 to get a temperature of 17 °C for the room. General temperature at main control 20°C + offset value from slave control -3 = room temperature for this slave control of 17 °C.
How can I include such behavior in Home Assistant especially in Lovelace UI?
To display the values for the individual rooms I have created a template which implements the simple calculation for me, no issue. But what do I do if I want to set a temperature for a room via Lovelace?
For example I would like to use the " Thermostat Card" (Thermostat Card - Home Assistant).
Thanks for your help.
Greetings
Joe
