Z-Wave JS Failed after HACS Install

Installation
1

Hello,

I’m a newbie to Home Assistant, but have used other home automation systems before.

I have Home Assistant Green, running 2025.5.1, and an Aeotec Z-Stick 7. Everything has been working perfectly for a month or so.

Today, I tried to install HACS, but I’m not sure if I did it correctly or not. When Home Assistant restarted, I noticed that, under Integrations, Z-Wave JS says it Failed to set up.

I did make a backup before installing HACS but restoring that hasn’t helped. I searched around and only found one post about Z-Wave failing after a HACS install, but that didn’t help.

Any ideas of what I can do to get this up and running again? What is strange, is that a few of my Z-Wave devices still work, but other do not. I’m not sure what the difference between them is.

Thank you for the help!

Installing the third party integration HACS should have no effect on the Z-Wave JS add-on. They are in separate containers.

Check your logs to see what is amiss. Settings → System → Logs.

Look at the Home Assistant Core and Z-Wave logs (selectable at the top right of the page).

I appreciate the suggestion. I was able to figure out, that right before I installed HACS, I was trying to get a double-tap on a Zooz switch to trigger an automation.

I think what happened is that I messed up and used the same Node ID for that switch that is used by the USB ZWave controller.

The problem now is that I cannot figure out a few things:

  • If I restored a backup from before making the Node ID change, how come there is still an issue with Z-Wave JS still not setting up?
  • How can I delete the switch from Home Assistant? I can see it listed as a device but I’m not able to find a way to delete it.
  • Googling I found that I can manually delete it from .storage/core.device_registry, but even after installing File Editor, I am not able to find the .storage folder.

Any advice on next steps, even a full reset would be very much appreciated.

Thank you.

After much more Googling and some ChatGPT, I installed Samba Share and was able to access the Core.device_registry file.

I deleted the section that had the Zooz switch I had changed and now everything is working again!

p.s. I did reinstall the Zooz switch.
