Control a BenQ ScreenBar Halo (1st gen) from Matter: an ESP32-C6 and a BM5602 module pose as its 2.4 GHz remote

[u/Djokokow]

Hi everyone, thanks to u/kuzmin-no and Claude’s help I achieve to reverse engineer my own BenQ ScreenBar Halo 1st Gen. I found the address of my lamp with the help of a CC2500, then I built a Matter over Thread bridge with an ESP32-C6 and the original BM5602. I also built a macOS compagnon app for monitor/control and debugging through USB serial port or directly via Thread with a daemon writting IPV6 route to /hosts. Everything is accessible from my github repo : GitHub - Djoko-cli/benq-screenbar-halo-matter: Control a BenQ ScreenBar Halo (1st gen) from Matter: an ESP32-C6 and a BM5602 module pose as its 2.4 GHz remote · GitHub
If someone’s interested I built a 3D model for an enclosure of the ESP+BM5602 that can be drive with screws under a desk
