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.
