Sorry, Matter indeed does not « need » Bluetooth, but on the other hand, if you have Bluetooth on the server, you can directly pair a Matter/Thread device without going through an app (personally I use the poorly translated and buggy Aqara app).
I came across the segment of this video: https://youtu.be/ewb41hv39bg?si=1mOZXzV6xdW-REZW&t=727 which points to this one: https://www.youtube.com/watch?v=hztYjL5yU3E where it’s well explained for Home Assistant (HA).
What do you think?
