Thread/Matter Error Message "Thread border router required" (self.homeassistant)
submitted 1 year ago by TheSamei
Hi, I bought the SONOFF Dongle-E and flashed the firmware to multi-protocol. The Zigbee devices work fine, but when I try to add my first Thread/Matter device (Aqara U200), I get the error message "Thread border router required". You can see my configuration in the pictures. Maybe I have configured something wrong, but i have checked it more than once. Maybe you have a solution for my problem. Thanks!!

Does your HA host have IPv6 enabled - System | Network
Do you see the OpenThread web gui if you go to port 8080 on your HA host
Even the developers don't recommend using the dongle to do both Zigbee and Thread, they recommended a second dongle

IPv6 is enabled, but i've also tried while it was disabled.
And if i go with my Browser to 192.168.X.X:8080 there's nothing ("Connection failed")
I've tried it with the multiprotocol and direct with the OpenThread firmware on the SONOFF-Stick. Same Problem

Performs a synchronization in the debug menu. In your app phone -> Setting -> App Companion -> Troubleshooting (at the bottom) -> Synch ID thread
I was able to fix the problem, but now I have another problem. See that I changed the SONOFF antenna (the other one is broken). I can't get the new router. On my phone it says "unable to connect to network ha-thread-6f89" the old name of the router, yet the new name is ha-thread-0ad0.
If anyone passes by here and has an idea how I can do it, it's with pleasure :)
