From the logging it looks that it is working. But it looks that the Eurotronics has problems receiving the temperature with quantities.
What I actually did not find how to translate the itemRegistry.getItem(“AZNA_Temperatur”).getState() into a number without a unit (Quantity).
I don’t know Eurotronics, so I don’t know, if you could somehow configure the binding or your devices to use UoM-items.
AFAIK there’s no built-in function for that. You could regex the hell out of it with a function to strip the unit(s), you could just replace the temperature unit (items["ITEMNAME"].toString().replace(" °C", "")), or you could just leave the DSL as is, as it is working 100%.
That’s why I would never use openHAB as the sole logic. In my setup I use KNX actuators for the heating regulation, which are completly reliant - what I do via KNX-binding is to tell the room thermostats, which temperature they should use or based on our calendars, whether it’s homeoffice-day (usually these days!) or vacation days (=house empty) and when to heat the house up, fire up warm water, … a few hours before our return.
what you could also do - either use a proxy item (in OH3 simply connect both items via the “follow” option) without UoM and use that for updating your Eurotronics or strip the UoM from AZNA_Temperatur…
That with the follow is also a good idea. Just read it yesterday evening. But actually I’m not shure.
I have two items. One from the netatmo, that shows me the Temperatur, and the second from the heating regulator. That is the input Temperatur to regulate.
How is the setup then?
The input on then heating regulator needs to follow the temperature on the netatmo thing.
So do I need to create a second item in the regulator temperature and set that to follow?
