After about 4 days the problems started again.
I set up a whole new system with new raspberry, new sdcard, new zwave-stick and i didn`t copy a single file from the old system but my new system got the exact same problem after one day.
the interesting part is, that all commands look good in the log files but outside the system nothing happends.
i press a zwave button to turn on a hue light, the buttonpress is recognized and the log says lamp recieved command on lamp predicted to become on but the light stays off.
same if the target is a zwave device.
telegram text masseges are send properly.
i noticed a warning in my logs
2022-08-28 09:33:07.331 [WARN ] [ence.internal.PersistenceManagerImpl] - Querying persistence service 'rrd4j' takes more than 5000ms.
and i had some problems with the log viewer when i made the new system.
