Sync two rooms, with a door sensor

[RubenKelevra]

I would like to specify two thermostats for one entity of this custom component. I think that's currently not possible, right?

I need to specify more combinations to fully replace my automations for heating:

In the bathroom I like to heat to a higher temperature than the hallway, but only if the door of the bathroom is closed. Else I like to fall back to whatever state is set in the hallway.

So basically that's a master/slave relation with the door as a binary switch to link them or not.

The hallway would be the master if the door is open, and whatever is set in the hallway would be set in the bathroom. If the door gets closed the bathroom will switch back to normal operation.

Yes its not possible right now.

i thinked about a combination with door sensors to make sure the thermostats turned also off if a door between two rooms with a open window is detected. but it seems to difficult to create a rule that matchs everybody needings.

Let me convert this to a disscusion, maybe we find a usable soulution

We can add for each TRV a config that binds a other climate aka virtual TRV to it, is also needed that a door sensor is added,

if the door sensor is open and the window, the TRV itself and the climate from the config are tured off.

Have i any mistrake in thinkging?

No that's wrong. I want a master and slave relation - not that a radiator turns off.

So if the door is open and the slave has say 21 °C, but the master has just 18 °C, I want the slave to change the set point.

Reason is simple:

The bathroom needs to be warm, except if the door is open, then trying to heat it further than the hallway is bs.

But heating the bathroom with the hallway radiator makes no sense either, so the bathroom need to adjust down to the hallway setpoint.

I think that could be implemented but currently it would be easier to make an automation to archive the wanted behavior
Maybe later that could be a thing. I have also some automation to make my heating smart and I think you have much more possibilities with automations.

Could look like this:

climate:
  - platform: ai_thermostat
    name: room1
    thermostat: climate.tvr
    temperature_sensor: sensor.temperature
    window_sensors: group.office_windows
    weather: weather.xxx
    outdoor_sensor: sensor.outdoor_temperature
    off_temperature: 20
    window_off_delay: 0
    valve_maintenance: false
    door_sensor: group.doors_room1_2
    linked: climate.room1
  - platform: ai_thermostat
    name: room2
    thermostat: climate.tvr
    temperature_sensor: sensor.temperature
    window_sensors: group.office_windows
    weather: weather.xxx
    outdoor_sensor: sensor.outdoor_temperature
    off_temperature: 20
    window_off_delay: 0
    valve_maintenance: false
    door_sensor: group.doors_room1_2
    linked: climate.room1

Of the door sensor is open and a window is open, the linked climate is also tured in window mode

I don't think it was helpful to make a discussion out of this, as this isn't a question. It's a feature request, so I'll open the ticket again: #13
