I recently updated to OH 5.1.0 w/o issues. Yesterday my CCU3 (version 3.79.x) started to behave strangely (tried to change Temp settings on a legacy HM-CC-RT-DN via web interface which were simply ignored). So I updated it to 3.85.7 (current version). This did not solve the problem so I restarted the CCU3 using the web interface again. The CCU3 did not come up again so I had to powercycle it. It then came up as expected. I restarted OH afterwards. Now openhab.log is flooded with messages like this:
2026-01-09 10:39:48.325 [WARN ] [ternal.handler.HomematicThingHandler] - Channel
not found for datapoint ‘000xxxxxxxxxxx:1#VALVE_STATE_TOO_TIGHT’

I rebooted the CCU3 and openhab again this morning but that did not help.
I have about 50 Thermocontrollers attached so I would like to avoid removing and adding them …
Any suggestions ?
