Hi All,

After updating zwave js addon this evening to version 0.1.85 it stopped working with this error in the log

[19:25:34] INFO: Service restart after closing

Is it just me or ? Any idea how to fix ? restore of addon backup did not solve the issue.

Any help welcome,

Edwin

I think it’s the Z-Wave JS UI update 1.15.4.
the previous errors in the logs are fixed, removed legacy network key and remove a space in the S2 security key.

If I stop Z-Wave JS UI and restart Z-Wave JS it works. Otherwise the log shows that the zwave device is in use.

}

Rollback to previous version does not solve the problem.
I will stop Z-wave JS UI for now

Same here, after updating zwave js ui it does not show any more devices, also connecting from devices to add-on does not work anymore.

The latest Z-Wave JS UI does have problems, but this error doesn’t look like one of them. It appears you are running both the Z-Wave JS add-on and Z-Wave JS UI add-ons at the same time, which is not allowed. Is that the case? https://www.home-assistant.io/integrations/zwave_js/#can-i-switch-between-the-official-z-wave-js-add-on-and-the-z-wave-js-ui-add-on

What are the problems? I haven’t read about any until this.

Thanks for the info. I literally just read the thread in the first link.

I guess it’s a good thing I never live on the bleeding edge with updates.

I’m still running zwavejs-ui 8.15.0 & and zwavejs 10.17.1 and I guess I’ll be waiting a bit longer to update.

@freshcoast thx, always had both addons running without issues. rtfm! :sleeping:
Uninstalled and restored backup of z-wave js ui 1.15.3, restart HA and z-wave device are back online.
1.15.4 does not work, no devices.
