xiaomi sensors to mqtt

README.md

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 6265 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)
