I have an issue with one of my items, though I’m not sure whether the knx Binding actually covers this.
The use case: our heating also serves as a cooling, but we have to manually switch it via knx. Therefore, I have set up a knx channel (in my knx things description):
Type switch : Kühlung "Kühlung" [ ga="<3/4/0" ]
Switching this on/off works fine - I can see that in the bus monitor for knx.
However, in the sitemap/page the changed state is not persistent, i.e. if I switch the item on and then leave the page/sitemap and go back again later, the switch looks to be off.
Could that have to do with the data type? It’s a rather uncommon one, 1.100
Would it help to put in the data type into the things definition?
Just for info: all other “knx switches” (with other datatypes) work perfectly fine and as expected.
You don’t need to set the correct DPT here (knx bus does not differ between sub-DPT). But a question:
Did you restart openHAB after setting up the UI/Channel/Item…?
Yes, that was the first thing I tried after setting up the item, restarting OH.
Maybe another issues comes into play here, though I’ve never had any issue with this before:
I have an KNX IP Gateway set to Tunnel. The KNX device, however, was converted using the GitHub project from @jo47011 - the knx file generates a thing with the adress 0.0.0. Meaning I only have one knx thing with all the GAs as channels in there. This thing is always offlinem but I can still control and see/read the values of every channel/item.
Is this the Bridge or is it the generic thing?
The former is ok, the latter is completely wrong, as a generic knx Thing, representing the whole bus but not a single device must not have any address (i.e. “individual address” in english or “physikalische Adresse” in german).
