I’m using OH3.1 Build 2276

don’t know what it is and where it comes from.

I’m getting this error in my first post once a day. And I get this Warn:

[WARN ] [ternal.handler.HomematicThingHandler] - Channel not found for datapoint '000A5BE99F4B3E:1#ERROR_DEGRADED_CHAMBER'

In the UI is no channel and I have no Item. In the discription of the HMIP-SWSD ist no channel declared. Don’t kow what this is and where it is comming from. Is this warning possibly the cause for my first post
