xiaomi sensors to mqtt

V 0.1: Initial version

Listen to sensor reports of a xiaomi home gateway. This is an early version and it will be improved over time.

What's working is:

  • reliably report motion state
  • reliably report door/window state

Whats missing yet:

  • turn motion sensor off, if there's no update within ~65 seconds (minimum open state interval is 120 seconds and could be reduced to 62~65 seconds)
  • retain values for door and motion sensors
  • not all switch reports are handled properly (unhandled no_close)
  • not all cube reports are handled properly (unhandled rotation)
