Creating a switch for an existing heater entity

Hi, I have in my living-room two adax heaters, integrated with the Adax integration.

The problem I am trying to solve is to have HA control the heater through an external temperature sensor (The internal ones are not working properly in the heaters).

I have looked up various smart thermometers, but they rely on a switch it seems.

So,

  1. How can I create a switch which sets the temperature to the desired temperature when on, and a low temperature when off
  2. A thermostat which can handle the above description.

Thank you for you attention :slight_smile:

Hi,

I was dealing with a similar problem (not ADAX heater though).

My approach was to set Generic Thermostat with external thermometer and an automation to set the temperature on the actual device to 35 °C when generic thermostat demanded heat and to 5 °C once generic thermostat stopped heating.

I hope this helps.
