Passing External Temperature Sensor Values to Thermostat

Hi everyone, I’m trying to pass the values from an external temperature sensor to my thermostat. Specifically, I want the ‘number.wohnzimmer_remote_temperature’ to receive the value from ‘sensor.temp_wohnzimmer’. I’ve been using both A Better Thermostat and Advanced Heating Control, but I’m not sure if I’m missing something in the configuration. With Advanced Heating Control, could it be that the local calibration settings are affecting this? I’m hoping someone might have a solution or some advice on how to set this up correctly. I’d really appreciate any help! Thanks in advance!
