Z-wave network down with restart loops in logs

Configuration Z-Wave
1

Not sure what’s going on but updated like an hour ago to z-wave js addon 0.10.0 and now some nodes are not showing as online and even the ones showing up are not able to be controlled from home assistant.

The addon logs start up normally for a while then start spamming like this

I completely restarted my home assistant yellow and then I restored the addon to 0.9.0 from yesterday’s backup but that hasn’t fixed the issue.

Also seeing the occasional log like this

2025-02-13T01:16:37.111Z CNTRLR   Failed to execute controller command after 1/3 attempts. Scheduling next try i
                                  n 100 ms.

Controller is a Zooz ZST10 with firmware 7.18.3

Been running it for maybe 2 years now and never seen this issue.

As suggested in Z-wave suddenly down I disabled the hardware watchdog in the z-wave js addon settings and so far that seems to have resolved the issue.

Why would this suddenly have showed itself when this wasn’t a problem for years?

Strange that this just suddenly became an issue and restarts would not resolve it. I even unplugged and replugged the controller.

Is this an early sign of controller failure?

I have the same issue since since the update an hour or two ago… turning off the watchdog didn’t help

4

Looks like I had to go into show unused configuration and disable it there as well. Seems to be working now.

5

Yeah that’s where it is, a bit hidden. It’s separate from adding service watchdog.

i cant find the watchdog setting… nor the ‘show unuused configuration’

how do i get to it?

nm found it. was looking in zwave js and not the actual add-on. thanks!
