Matter Devices keep Showing Unavailable

Over the last few days my Inovelli switches continue to show as unavailable. They become available briefly but then they become unavailable again. I’m running

  • Core 2025.1.1
  • Supervisor 2024.12.3
  • Operating System 14.1
  • Frontend 20250106.0

Is it possible that my 2.4ghz WIFI is interfering with my Thread Border Router? The Border Router runs on channel 14 and my 2.4ghz is running on channel 1.

Also when I ping the device I get IPV4 and IPV6 but another address that doesn’t ping

What information can I provide to get this rectified? Thanks

Anyone else having unavailability issues with inovelli switches?

No, I have over 25 White switches are they are rock solid. Matter device unavailability usually (not always) points to a local network issue of some type.

Please make sure your router is not restricting access to known devices (MAC address filter). Took me days to identify why matter/thread network was unreliable, same as you described.

I must admit that this wasn’t the solution as devices still became unavailable after some time, unfortunately. I now have locked the WIFI channel to 11, which make all my 6 tado X devices show up fine since last 3 days. Keeping my fingers crossed…

I changed my 2.4ghz channel to 11 and all has been working for about 7 days now
