Transfer a value of one device to another

[Burki24]

The desire for a new function:

Will it be possible in a further version to transmit values (e.g. a room thermostat) to another device (e.g. a radiator thermostat)?

The idea behind it: The Bosch thermostats (https://www.zigbee2mqtt.io/devices/BTH-RA.html) make it possible to use a temperature from an external sensor (instead of the integrated one). Unfortunately it is not possible to achieve this via bindings.

Therefore, this option in the extension would be very desirable.

You can make simple automation if-else. For example:

thermostat:
  trigger:
    platform: numeric_state
    entity: Temperature Sensor
    attribute: temperature
    above: 25
    for: 60
  action:
    - entity: Thermostat
      service: turn_off
