Trying to get Matter/Thread working (lemmy.world)

I'm trying to start using Thread devices in Home Assistant for the first time. I've gotten a Sonoff Dongle Plus MG24, flashed it with OpenThread firmware, added it as an OpenThread Border Router in Home Assistant, and added the Matter integration.

However, when I try to commission a Matter/Thread device using the Home Assistant companion app on my GrapheneOS phone, I scan the QR code, get to the screen that says "power on your device and make sure it's in setup mode," and "connect your phone to your main 2.4GHz network" and tap the "I'm ready" button, but then it gives me an error that I have "no Wi-Fi connection" even though it is definitely connected to the correct (2.4Ghz, not 5GHz) network.

I've also checked that the Home Assistant app has all the necessary permissions (network, nearby sensors, etc.)

Help?

Edit: I just found these bug report threads that look like they're relevant, but I'm still reading through them:

Interesting that you can use BT for this. I have a spare googled phone for stuff that doesn't work on graphene that I don't feel like troubleshooting for more than a few hours that I used to add an aqara deadbolt.

Honestly, after all the troubleshooting with matter (I didn't have ipv6 prior and didn't really see a need internally for it) I wish I had gone with a different deadbolt as it was the first matter device and currently still only one.

The normal consumer smartphone pairing flow uses Bluetooth on the phone to do the initial device pairing after you scan the QR code.

You just aren't made aware of that as the user.

The on-server flow also needs Bluetooth therefore, and all that's different is you manually type the numbers from the QR instead of using the camera to scan :)
