Wow! Great! Thanks for sharing!
Why this solution is not integrated in Home Assistant?
The Aqara door/window sensors MCCGQ11LM won’t appear in Home Assistant if you don’t modify that two files (components/homekit_controller/binary_sensor.py and components/homekit_controller/const.py) like @steck details.
PD: It will be great if you could place that two files for download in same place, so it will be easier for those who want implement this modification. Edit that files manually is quite tricky
