Using external temperature sensor to control temperature (TRV)

Hello, I’m quite new to HA and have purchased a Home Assistant Yellow.

Now I’d like to control my TRVs using an external temperature sensor:

TRV: Siterwell GS361A-H04
Temp sensor: Xiaomi WSDCGQ11LM

Those are connected via Z2M. Is there a straight forward way to use the external temp sensor instead of the external one? The external is preferred because of accuracy. I have tried “better thermostat” for a while, but it wasn’t reliably working with my hardware.

Any help would be much appreciated. :slight_smile:

In ZigBee it is called a binding.
See if this can be used.
