Openhab2: reading/writing values to/from heating device


is there a guide how I can read/write temperature values from/to heating devices?

What typ of device do you have?

MDT AKH-800.02 heating aktor and “mdt GT2T Glastaster 2” as the sensor

I can now read the temperatures, thank you :slight_smile:
Is there a way to set the desired temperature?

The exanmple is not for KNX, but you can use that.
