Commission new device Python Matter Server - Greyed out

Hi
I am trying to set up a matter over thread network.
HA yellow, onboard radio is running zigbee through Z2M.
Sky connect into USB on the yellow.
Thread network is set up, set as preferred, credentials sent to phone.
Matter integration set up with Matter Server supervisor add-on.
Matter server is running.
I click commission node and the option to add new thread device (and also wifi) is greyed out.
Any idea what I am doing wrong?

IPv6 is set to auto in network settings

Few error messages in the matter server log:

> CHIP_ERROR [chip.native.CTL] Shutting down the stack...
> s6-rc: info: service fix-attrs successfully stopped

If you are also using the HA OTBR, then the HA Companion App is the preferred method of commissioning a Matter/Thread device (using UI->Settings->Devices->“+ Add Device”). The Python Matter server Web page you are showing is a way for the HA Matter Server to do the commissioning directly (not using an App) and from my understanding this is considered a “fallback” method of commissioning a device. I’ve used this fallback method and it generally works. However if you use this “fallback” method, it requires a Bluetooth USB stick (which should be the reason those lines are grayed out) and you have to be careful if the Bluetooth Integration is using this stick.

Thank you that’s great
I have a device set up
Is there a way to see the network mapped and signal strengths?

Sorta, but not really. There is something that comes with the OTBR AddOn, but it was not designed to do what one generally expects, so you will be disappointed in its capabilities.
If you want to see what it is, go into the OTBR AddOn configuration and enable the Web server using port 8080, then with a browser go to http://homeassistant.local:8080/ and click on topology
