Hello, I managed to get home assistant running on an old PC. I'd like to connect my matter over threads devices. I bought a sonoff lite dongle. I followed this post https://www.reddit.com/r/homeassistant/comments/1qknmhq/tutorial_matter_thread_border_router_setup_with/. I set up the openthread router than installed the thread integration. It says "You don't have a preferred network yet.". Do you think this may come from the dongle not being flashed / recognized correctly ?
