I use for month the MQTT Binding in order to communicate with my Buderus Heater very well. Normal operations like transformation OFF=0, ON=1 are working as expected.
Now I try another step. The heater sends out an error string via MQTT. If everything is okay, this value is “0”. Otherwise it will indicate the type of error. Can look like “1,2,3…1A,2b” etc.
Is there a possibility to use the binding like that:
Switch Error = OFF -> MQTT Value = 0
Switch Error = ON -> MQTT Value != 0
Thanks in advance
