Pairing two Zigbee devices

[IJssel (Ruud)]

I have a Zigbee smart radiator valve and a Zigbee temperature sensor. How can I connect the temperature sensor to the radiator valve, so that the temperature setting of the radiator valve is controlled by the temperature sensor.

I don’t know if this is exactly what you are looking for but you may want to check out the following blueprint:

TRV Calibrator - Calibrate your valve with an external sensor (probably TRV agnostic)

The thermostat inside your TRV is probably telling your the wrong temperature and the reason for that is the proximity to the radiator. One way to workaround that is to use an external temperature sensor as reference and actively update the calibration. After adjust it for several days I finally came up with a blueprint that seems to work fantastically to my valve and I’d like to share it with you.
