We just glued the magnetic holding frames the remotes come with next to the wall switch. Also the bulbs are set to stay off when being energised so everybody has to use them.

Remembered I have a Conbee III laying around so I flashed it to the OpenThread firmware. Turns out, HA itself handles the devices (you add matter devices in HA settings) and the Conbee is really just the antenna. So no container like Z2M or deconz in the middle. That makes a whole different situation than I assumed above. Documentation was not intuitive but I got it going for me, which is nice

Hows that working software-wise in HA? One running in Z2M, the other ZHA?
