Hi there,
I think I have figured out the entity myself by now:
In my system it is called sensor.priority_31029 (don’t know whether the number is everywhere the same or random?).
I believe this follows the Modbus common register ‘Operating prioritisation’ with its values
10 - off
20 - hot water
30 - heat
40 - pool
60 - cooling
Due to the weather conditions, neither the heating nor the cooling is currently starting, but I’m observing at least switching between the states ‘OFF’ and ‘HOT WATER’. So, the other states will probably be ‘HEAT’, ‘POOL’ and ‘COOLING’ (I’m wondering why in HA it’s expressed in capitals and I also don’t know whether HA also supports the numeric values?)
Unfortunately, HA seems to not supporting attributes nor values of this entity so I’m not succeeding in defining any working logic into automation triggers so far?
