Homebridge Pi Garage Door Opener With Sensor

This is a homebridge plugin to make a Raspberry Pi connected with a Relay Board into a Garage Door Opener, via the Home app on iOS using Homekit. It uses a magnetic switch to determine the state of the garage door, open or closed. The wires from the Relay go into the same ports as the wired button for the garage door. When the Relay closes the circuit it acts like the button was pushed.

How to Setup

Both homebridge and this package will be installed globally with the following commands.

sudo npm install -g --unsafe-perm homebridge
sudo npm install -g --unsafe-perm homebridge-garage-door-wsensor

Rename config.sample.json to config.json and place in .homebridge/config.json

How to Start

Run the following command

homebridge

Sample Config

Rename config.sample.json to config.json and place in .homebridge/config.json Most likely you will need to play with the settings for the door sensor. Depending on your hardware configuration you may need to try different settings for "invertSensorState" (true, flase) and "input_pull" (up, down, off).
