Z-Wave Mesh Issues (ZWave devices unresponsive after platform update)

I am experiencing multiple issues that seem to stem from my Z-wave switches. They are not responding, and when they do function, they don't accurately display their active states. There's also a significant delay of about a minute, and as a result, none of my routines are working. I have already attempted several troubleshooting steps, including reverting to an earlier version, rebooting, rebuilding the database, and rebuilding the Z-wave network.

Many Zwave anomalies have been resolved by shutting down the hub, pulling power at wall plug, wait ~30seconds, power back up.
This (removal of power) resets the Zwave hardware.

Definitely do the shut-down/reboot as @TArman suggests.

More data should be helpful...

  • What hub do you have, C8, C7, C5?
  • What platform version is your hub on?
  • What brand/model Z-Wave switches are you having problems with?

Have you added any new Z-Wave devices during the time when your issues began to appear?

I haven't added anything new to my hub; it's been running with no issues. The issue started after the update, or maybe it's just a coincidence.

C-8 Pro

Currently running version: 2.4.3.133

These are symptoms of one or more misbehaving devices.

You don't need to add new devices for existing ones to go bad. I would post a screenshot of the Z-Wave Details table, otherwise troubleshooting each device to make sure is working properly may be required.

Did you try the โ€œpower pullโ€?

One thing to check on C8 and more-so on C8-Pro, is to make sure that you're using the power supply that shipped w/the hub. Z-Wave issues like yours can arise when using POE or other power suppplies.

And as @TArman notes - the shut-down/pull power/wait 30s/restore power process can often resolve problems by restarting the Z-Wave and Zigbee radios.

Yes, on the power pull

None of this is useful to diagnose issues. Can you please post what @bobbyD requested? A screenshot of your entire z-wave settings page.

Do not copy/paste the text on that page. Post a screenshot.

Your z-wave mesh has at least two z-wave ghosts that need to be removed. Nodes 0x0008 and 0x0012.

Could you please execute a Rebuild network on Z-Wave Details page and let us know if you get any failures.

Looks like you will need to further investigate your physical devices to identify which ones are bad or misbehaving. Power cycling the devices and observing which ones may have gone bad is your only way out of this. After completing the physical walk through, go back and re-run the rebuild. You want all devices to complete without failure.
