How to link thermostat with external thermometer

I dont think so. It has option to connect external sensor, but not the option to replace it by pushed temperature afaik. It wasnt possible with Fibaro neithet.

Hi. I did not read thru 100% of the text but the original question was how to link a thermostat to a tempsensor, right? The answers is, you don’t have to. You simply add them to the same room or zone and this is then automated.
Not always perfect but very simple!
