Homebridge is an Open Source project for creating a bridge between automation devices (not certified by Apple) and HomeKit. You will be able to order, receive measurements from sensors (motion, presence, temperature, water leaks …) on all your iOS devices using the application Home. You can even order your devices out of home if you owned an Apple TV or a compatible iPad. Here is a series of posts to learn how to install and configure Homebridge and necessary plugins to communicate with a Home Automation software (Domoticz, Jeedom …).
