Simulate Madoka room thermostat with P1P2Serial

[nicx]

Is it possible to simulate an external Madoka room thermostat with the P1P2serial module?

My idea: activate the external room thermostat function in my Altherma, then setting the current room temperature with the p1p2 module by writing it via MQTT to the Altherma. with that, I could set the desired room temperature and control the behavior of the Altherma.

My understanding is that the only missing feature is writing the room temperature to the correct register.... or maybe this is already possible?

This is not yet possible (or not yet known how to), but I hope to dive into this and get it to work. If not, I have been working on a work-around to achieve the same effect.

A fake room temperature can now be generated by the P1P2MQTT bridge for Daikin E-series systems. This may help to avoid an error message on certain systems that the bridge does not generate a temperature, but we do not know which systems require or accept this.

Command F1 will switch this function on, with default reported room temperature of 20.0C. Command F1 205 will change the fake temperature sensor to 20.5C. The permitted room temperature range is 0.0C-25.5C. Command F0 will switch this function off. By default this function is off. It will also switch off after an ATmega restart, the state is not yet stored in EEPROM.
