motion Device

A motion device exposes a motion sensor connected to a GPIO pin. Homebridge RPi configures the GPIO pin for input. By default, Homebridge RPi configures the internal pull-up resister for the GPIO pin. Homebridge RPi configures pigpiod to send real-time notifications when the GPIO state changes. Homebridge RPi debounces the input signal.

The device is exposed as a separate HomeKit accessory, with a Motion Sensor service. Through this service, you can monitor the motion sensor state in HomeKit, or even configure HomeKit push notifications. The accessory mimics an Eve Motion, exposing a History service, so Eve shows the history of the motion sensor state.

The motion device uses the following config.json keys:

key	type	Description
name	string	The name for the device in HomeKit.
gpio	integer	The GPIO pin.
pull	string	The configuration of the internal pull-up/pull-down resistor for the GPIO pin: off, down, or up (default).
reversed	boolean	The device state is reversed, i.e. report motion when the GPIO pin is high instead of on low.
debounceTimeout	integer	Time in ms to ignore state changes after initial change. Default 20ms.
