Can anyone explain how to connect a thread/matter device directly to HA yellow using the internal adapter

Hello there,

i am new to matter/thread and i bought a device which is matter/thread and i want to connect this to my HA yellow.

Can anyone please explain to me how this is done?

I now spent hours on this and it does not connect.
I read many articles here and spent hours of configuring things i dont even know if i need them and no luck.

Please, someone help me, please.

I don’t know if this is still an issue for you, but I just posted a solution that worked for me.
