I have some problems with my GL-S200 matter over thread with home assistant.
I connected my GLS200 in wifi and my HA in cable to a router. I selected “wlan-sta0” and opened port 8081 TCP/UDP on the GLS200 as indicated in the documentation. I’ve managed to set thread and matter on my HA (i see my GLS200 thread router), but when I want to add a matter device with the home assistant app, it can’t find the border router…
Does anyone have any ideas?
I am fighting with similar issues here.
My immediate suggestion for a test would be to disable IPv6 on your main router (not the S200) and try again.
