Just updated to the latest companion app and noticed the import credentials button for the thread networks. I also have a (new and updated) homepod mini. trying to import the credentials from the homepod mini I get an “error unknown type 74” message. it loops from there if I retry.
I’ve tried resetting the thread network on the HA side. running a sonoff 3.0+ with the multi protocol for HA thread access.
I have the same issue here. I’ve currently not got a coordinator attached to the HA server.
I’m getting the exact same error with no clear info on what to do.
I have the same issue too with a HA yellow. I have managed to pair matter eve energy sockets over thread to HA with QR codes generated from apple home, but I cannot choose the the apple border router (apple tv 4k) as the preferred network and I get the same error when I try to import credentials.
I´m getting the error, too
Having the same problem here. Were you guys able to find a solution for it?
Unfortunately, I’m still dealing with the error. No word from HA devs either.
Same error here - unfortunately no solution…
It now works for me with the latest update 
Same here as well. This is a huge win. It wasn’t clear whether this was due to a change in the Home Assistant app or something fixed in an iOS release as I previously had issues onboard Matter devices into Homekit too but that now appears to be working too.
