I’ve been trying to get Matter over Thread to work without success. I have Unifi and am fully aware of the Unifi IPV6 VLAN mDNS challenges. This is already attempt #3 after some rage quits… 
(Thread HA and VLANs - will this work? - #5 by wmaker)
My Unifi network setup:
| Network | Vlan | Wifi | Used by | IPV4 | IPV6 |
|---|---|---|---|---|---|
| Main | VLAN1 | n/a | homeasisstant, DNS | 192.168.1.4/24 | fd00:1::/42 SLAAC |
| Users | VLAN20 | Wifi_Main | phone, laptops | 192.168..20.4/24 | fd00:20::/42 SLAAC |
| IOT | VLAN30 | Wifi_IOT, Wifi_IOT24 | OTBR RPi, Matter Devices | 192.168.30.4/24 | fd00:30::/42 SLAAC |
I know unifi and IPV6 dont place well so i need to find a way to make it work. I realized that my main wifi is not in the same VLAN as the HA instance, maybe also adding to the IPV6 mDNS issues.
To deal with the routing challenges, I want to setup a standalone OTBR router on a RPI with fixed IP in VLAN30. Then use REST.API from HA to this RPI to connect HA to OTBR.
RPI has a ZBT2 connected on /dev/ttyACM0, uGreen BT6.0 bluetooth dongle and network port eth0. IPV6 forwarding is enabled. On the RPI i followed GitHub - ownbee/hass-otbr-docker: Stand-alone Home Assistant OpenThread Border Router docker container. · GitHub. Firewall rules from RPI to HA + return is unrestricted.
On HA I am connecting to OTBR router using the Rest API to http://192.168.30.15:8081
Afterward I joined my phone to the IOT “Wifi_IOT24”, setup companion app to HA URL IP address and Home Network = “Wifi_IOT24”.
MoT Credentials were synced before adding new matter devices. When adding a new Ikea devices, I am going through the credentials phase but then nothing.
what else can I do this time?
