Z-Wave Devices Going Unavailable, Need Help Resolving

Hey everyone,

I’ve been using Home Assistant with Z-Wave for many years and have been managing my Z-Wave devices through the Z-Wave JS UI add-on. I have a combination of ~50 powered / battery operated devices. Over the past six months, I’ve noticed an issue where devices randomly become unavailable throughout the week. However, if I ping the device, it comes back online.

This has been causing problems with my dashboards, which auto-populate light controls, and also with automations that don’t trigger because the device is unavailable.

Has anyone else experienced this issue? What could be causing it, and how do I go about fixing it? Any advice would be appreciated!

If it recently started, then I would suspect there is some new radio interference present. However, there’s not much you can do about that unless you can control it. Did you perhaps add a new routers?

You can set up an automation to periodically ping all the devices if that resolves it, though.

The only similar thing I have experienced is if there are too many devices sending out power reports too frequently it can flood the network and make devices unavailable.

Sorry I can’t be of more help.

Does anyone have a script example that pings all Unavailable devices like this?

This looks promising:

Got the same issue since some weeks but I cannot say if it is happening since a specific update or something.

I am currently having around 85 zwave devices with a zwave.me razberry board on a raspberry4.

Which hardware are you running?
