All light devices are unavailable after upgrade to zwave-js-ui 4.0.1

Configuration Z-Wave
1

Today, after upgrading the Z-Wave JS addon to 4.0.1, all of my light devices (probably 30 devices) are reporting unavailable. This is for multiple device manufacturers. My z-wave sensors and switches are working as expected. Odd that it’s just the light devices.

I’m running: zwave-js-ui: 10.1.1, zwave-js: 15.0.2, HA 2025.3.3.

The ZUI interface doesn’t show the controls for the devices. Normally there would be controls for turning the lights on, etc.

I see nothing useful in z-ui_current.log or zwavejs_current.log log files.

Considering the devices are not controllable from the ZUI web interface (but still showing up) and devices are unavailable in HA, should I assume this is related to zwave-js: 15.0.2 and not zwave-js-ui?

I don’t really see anything useful in the HA logs, either, other than what might be expeced if the device is unavailable:

2025-03-25 14:44:48.225 WARNING (MainThread) [homeassistant.helpers.service] Referenced entities light.kitchen_sink_light are missing or not currently available

Any pointers for debugging this? I can downgrade, but happy to try and debug. I’ve restarted the addon. I even rebooted.

Thanks,

I just downgraded to version 3.24.0 of the addon and all my lights came back again. Weird. Curious if anyone else experiences this loss of lights.

Maybe not the best way, but I downgraded the addon by changing the vesrion in supervisor:

# grep -F version /mnt/data/supervisor/addons/git/a0d7b954/zwave-js-ui/config.yaml
version: 3.24.0

and then let HA “update” the addon to the older version.

There are already multiple topics covering problems with add-ons 4.0.0 and 4.0.1. I’d wait for a new version.

Thanks. I’ll try and keep a watch for updates. This one seemed odd, so curious about it.

Perhaps it’s something else, but it’d be hard to say with the other issue still present. Unavailable usually means the node is dead, you could check that.
