I’m actually setting up a simple Temperature control for my HmIP-eTRV-B1 via OH 2.5.
My idea is to control the Offset Temperature of the actuator according to it’s differntial temperature, like in the forum-link below.
newOffset= XiaomiTemp - (ACTUAL_TEMPERATURE - [actual]TEMPERATURE_OFFSET)
The problem is, that the new Offset cannot be send to the piVCCU.
In the Log the following lines were written:
2020-02-27 15:30:00.115 [ome.event.ItemCommandEvent] - Item ‘WoZi_Heizung_Offset’ received command 2
2020-02-27 15:30:00.120 [nt.ItemStatePredictedEvent] - WoZi_Heizung_Offset predicted to become 0
In PaperUI I can’t find the channel “TEMPERATURE_OFFSET”, but regarding to the HmIP Device Document it should be possible, cz it’s read/write.
An Error " Datapoint not found" does not appear.
Is it possible do add this channel to the binding?
According to this Thread:
https://forum.iobroker.net/topic/20873/vorlage-homematic-ip-thermostate-mit-ccu-externe-temperatursensoren-xiaomi-etc-einbinden-mittels-offset-setzen/2, it’s possible via ioBroker. So in general it should be possible via OH as well, shouldn’t it?
Thx for your replies!
PS: I can post my code as well if you’re interested.
