Hey!

Here is my setup: Unifi UDR7 Router, two VLANs, IPv6 active on both.

HA Green Instance on IoT VLAN, Apple TV (4k, 2nd Gen) on Default VLAN.

I can ping the Apple TV (and my iPhone also on the Default VLAN) from the HA Green.

I have some Ikea Matter over Thread devices.

I can add the Ikea Matter gadgets to Apple Home without any problems, but I cannot add them to HA.

The Apple TV is set as border router in my "Preferred Network" in HA->Settings->Thread. I can send the credentials to phone.

In the companion app under Debugging->Thread I get two Apple Keychains (?!) which I can both transfer to HA.

Anybody any ideas for troubleshooting? Appreciate the help!
