but I don’t see the errors as suggested by another post where they get browser errors being reported.
P.S. I’m reasonably green.
The other issue I forgot to mention is when I readd, enable, reboot, whatever. Sometimes one or two of the zwave things show up as ‘OFFLINE - BRIDGE_OFFLINE’, while all the rest are ‘ONLINE’. Sometime a restart or unplug of the stick, or two, will fix it.
This may sound stupid, and may well actually be stupid, but have you tried another reboot?
My own RPi4 openHABian install update worked well, but after the first reboot there were a whole load of odd behaviours and bad log messages. Given a major code rework is incoming, I didn’t spend much effort saving logs for analysis (and the errors were bad enough to wake me up at 04:00 as restarting my rules generated speech messages!).
A second reboot fixed all issues, and 2.5.8 has been working fine.
My vague recollection is openHAB sometimes has to download new code after an upgrade (seemingly not via apt), or services don’t start in a clean order leading to problems.
It may be also worth trying Zwave changes using HABmin rather than PaperUI as it had more features (although finding them under Tools -> Advanced Settings can be more challenging).
