The Homematic-Binding is installed and running on a separate Raspberry 4 runnning OH.

Problem: After upgrading both Raspis from OH 4.3.3. to OH 4.3.5 (and upgrading piVCCU from
3.7xx to 3.81.5) the following warning messages are flooding the logfile:

2025-05-05 20:10:51.408 [WARN ] [ternal.handler.HomematicThingHandler] - Channel not found for datapoint '00201BE9A54794:1#VALVE_STATE_TOO_TIGHT'

2025-05-05 20:10:51.413 [WARN ] [ternal.handler.HomematicThingHandler] - Channel not found for datapoint '00201BE9A54794:1#VALVE_STATE_ADJUSTMENT_TOO_BIG'

2025-05-05 20:10:51.417 [WARN ] [ternal.handler.HomematicThingHandler] - Channel not found for datapoint '00201BE9A54794:1#VALVE_STATE_ERROR_POSITION'

2025-05-05 20:10:51.420 [WARN ] [ternal.handler.HomematicThingHandler] - Channel not found for datapoint '00201BE9A54794:1#VALVE_STATE_ADJUSTMENT_TOO_SMALL'

They are referring to (all 5) installed homematic thermostats (HmIP-eTRV-B).

Removal and reinstallation of the binding together with “openhab-cli clean-cache” and restarting on both Raspis didn’t solve the problem.

Try:

  • delete the thing “00201BE9A54794”
  • start scan from homematic binding
  • re-add thing from inbox

This helped on my openHAB 4 with all “Channel not found for datapoint …” messages from Homematic binding.

Thank you, your approach did solve the problem!
