Can you provide the part numbers of sensors you’re trying to pair? You said you managed to successfully pair one of each, that would indicate that the sensors are supported by both Z2M and your router. Did you physically move the router away from the USB ports? How are you running HA? Bare metal, VM, container, supervised?

Are you absolutely sure you got the P version? Did you do the setup for Z2M from scratch after making the switch? Are you using USB extension cable?

I used to have it but then i just had to throw everything away. Something something why is this junk in our house something something angry wife…

Maybe i should make a printable model but preserve the “original” “art” “design” 🧐
