That is a weird combo. And designed to lock you into their ecosystem. Absolutely proprietary.

This one runs BTHome, part of the Open Home Foundation. I have two mmWave presence sensors from the same company. They offer tasmota and esphome firmwares for them, I chose ESPHome. It's been great.
I have 3 Kauf RGB switches that I use for garage door interfaces spread through the house. Off means closed, orange means reed switch and range sensor don't agree (moving), white means open, red means fail to close.
The little corner light is for the pedestrian door.

The garage door itself has a konnected gdo.

Spiders like to obscure the range sensor ~twice a year, and it probably best practice to not have all the inputs coming from one device. One day I'll move the reed switch to the i4 dc shelly that reads the door switches. Maybe try ratgdo, the clone/knockoff I bought was not very reliable.
