no, i cannot found any errors in the openhab log.
only this message for each device:
[WARN ] [ernal.handler.HomematicBridgeHandler] - Device with address ‘000A9709904F69’ not found on gateway ‘3014F711A061A7D7098E12CB’
but some (same firmware + same hardware) are online and working in openhab.
I has found the solution. after a restart from openhab linux system, all working well.
can i in any case restart only the “needed” services? when i create a script and got the same error messages in log, that i then can restart the service? thank you so much for your help
You can restart openhab with sudo systemctl restart openhab. It should also be possible to restart only the Homematic binding via a Karaf command. But I have never tried it from outside the Karaf console.
