HomeKit was first announced at Apple’s Worldwide Developer’s Conference (WWDC) in 2014, as a framework for home automation. The name HomeKit was formed from “Home” for home automation, and “Kit” for software development kit (SDK). The idea is that all HomeKit devices work to the same set of rules, ensuring they can all work together. Once connected they can be setup in a single app and controlled using Siri, Apple’s smart, voice-controlled assistant in iOS. The first devices based on HomeKit reached stores in July 2015, and new accessories are launched every day.
