Errors while connecting matter devices to HA

Configuration Matter/Thread
1

Hi forum, im trying to connect matter devices to my HA. I pair them first with apple home, then get a key from apple home for HA. It fails most of the times and i see the following in the logs. Any one else encounter this?

Not sure, but my guess is that the device doesn’t have any/correct certificates/chain from the point of view of the HA Matter Server. The CSA organization facilitates these certificates for Matter, but it could be that Apple Ecosystem has a private copy of these certificates/chain while other ecosystems do not.

Is it one particular device type, or is it all of the different types?

These re Leviton matter enabled switches

4

Or the internet connection is not available to the Matter server, so it can not check the certificates.

5

the weird thing is, it works if you just keep trying…

6

If it is a Thread network, then I would look into moving it to another channel then.

7

this is matter ovrer wifi

8

Then it sounds like your IPv6 configuration in your network is faulty or bugged somehow.

9

Then its not a certificate problem… could be weak WiFi signal (say Leviton is inside a metal switch/outlet box), … there have been issues in the past timing-wise when pairing a device with an iOS App, but I think those have mostly been resolved.

10

I mean they are all added now

11

Signal on my unifi console for all of them are -50dbm or lower

Nice!, That’s an very good signal level
