Hey everyone,
After the Z-Wave JS UI 4.0.0 update this morning, nothing worked for me – no Z-Wave device was reachable – and I couldn’t interview them again – the error message states that they are no longer supported by Z-Wave JS UI.
I’ve never had any problems after updates on my Green – this is the first time.
The core update and operating system are up to date.
Is anyone else having the same problem?
(I’ve since restored the backup of version 3.24.0, and now everything is working as before).
Ping yes. Interview No. This can create more issues. Really it flood network and creates problems that way.
After update it may take time for devices to check in so these may be unavailable as a result.
If you are using docker, make sure you update the HA docker container. Sometime changes in zwavejsui requires HA update.
I have no devices! The serial driver looks like it crashes and keeps restarting. I can see that the z-wave controller responds , but then the serial driver crashes. Like an idiot, I didn’t make a backup before updating. Is there somewhere that I can download the previous version to install?
Thanks for your reply. I have 77 devices, and all of them had the error message described.
Maybe it was a mistake to interview her again, as @tmjpugh pointed out.
I too had this issue.
All z-wave nodes not found and this was with the system left alone for a out 6 hours.
I watched the z-wave js ui screen and also witnessed the serial port cycling through the unavailable state.
Had to restore the backup to 3.24.0 to get z-wave back up and running.
Home assistant yellow, all up to date.
Using the Zooz 800.
Restart host may bring it back. If not you need to verify it is mapped properly and connected
Unplug and replug it to USB is needed at times. Sometimes it hangs on old connection and won’t allow new. Reboot host should take care of that but sometimes it just doesn’t
It’s a Razberry board, not a USB stick. It does start to communicate, but the serial driver crashes when trying to discover device IDs by the look of it

UPDATE: I’ve learnt something new! Under ‘Backups’ one can restore individual addons, and luckily I had an earlier version.
All now working, but I’m a couple of versions behind.
Sorry, I’m only now able to reply because of the time difference (Europe)
Sounds interesting, but I can’t believe it’s the Z-Wave stick.
I had zero connection issues with the previous version, and 5 minutes later, after the update, there’s supposed to be a problem? I also restarted my HA after the update.
I can’t seem to figure it out yet, but I’ll try it as you described.
I have an HA green and an Aeotec Z-Stick 700 series.
My Z-Wave network has been relatively stable and I have done previous updates to Z-Wave JS UI without issue, but the 4.0.0 updates are causing multiple devices to be unrecognised and entities disappearing, only way I have found to get them back is to reinterview but frequently in HA it reports the interview as failed and yet when I watch the Z-Wave logs I can see the interview is still in progress - seems like a disconnect between HA and Z-Wave JS
