After I updated my CCU3 from version 3.85.7 to 3.87.6 my OH log is flooded with messages as shown above. I updated OH from 5.1.3-1 to 5.1.4-1 which didn’t help. I then deleted the HmIP things and reinstalled them in OH, which did not solve the problem either. Any ideas ? Thx Martin

Same here After upgrading CCU3 to version 3.86.7.

The solution is: remove the Homematic thing make a manual scan for new homematic-things add the new founded thing and give it the same label So all the channels and linked items remain intact.

Did not help in my case - see my original posting.

Same here - in addition to the #ERROR_OVERLOAD, which I have already since years (but definitely not so often as the new error).
Thx Dirk
