Z-Wave integration unable to connect to Z-Wave server (Failed to unload error)

[zavjah]

Describe the issue you are experiencing

Since several months I am having the trouble that Z-Wave integration stops to work with "Failed to unload" error. All the time I thought it is about the integration not working, why I also reported this in Error unloading entry Z-Wave JS for zwave_js. Since I thought it is about the integration, I downgraded to 2023.9.3 which didn't help. Error were less, though, but nevertheless, they came.

@kpine has looked into it and in his opinion this has to do with the z-wave js addon and not with the integration. So I am back on 2024.2.2 and error are again more often. This morning it didn't work for more than 20 minutes and than stopped :-(

I have no clue what is causing this issue as I didn't change - at least I am not aware of any intentional change from my side - anything in my setup. I have the same setup since my initial start and it worked for over a year. Since last autumn I have masive trouble with Z-Wave which most of device I have use.

Please find here all logs I habe from this morning:
240222_090700_home-assistant_core.log
240222_074100_zwave.log
240222_092800_supervisor.log

I see in core log is that shortly before the error popped up "something" (Integration) disconnected from server:

2024-02-22 07:46:48.459 INFO (MainThread) [homeassistant.components.zwave_js] Disconnected from server. Reloading integration
2024-02-22 07:46:48.507 ERROR (MainThread) [homeassistant.config_entries] Error unloading entry Z-Wave JS for zwave_js

Z-Wave add on stopped logging 5 minutes earlier after many "unexpected" entries for DRIVER. Does this mean server stoped to work there? This would explain why integration disconnected from it.

But honestly, I have no clue where to start with all this. I looked into open and closed issue of the add on but didn't find anything like the issue I have,

Please, can someone look into this and help me! thx,
Zavjah
