HomeKit officially became available in June, with the launch of the first HomeKit-compatible products, but as we've highlighted in reviews, Apple's home automation platform is still in need of some work to make it a viable choice for most users.
With iOS 9, Apple is debuting several new HomeKit features that have the potential to significantly improve the way it works, by simplifying some of the setup process broadening supported device types, and introducing key automation features to cut down on user interaction.
Setup
Setting up HomeKit devices isn't difficult, but it does require users to enter a unique HomeKit identifier to pair with an iPhone. In iOS 9, Apple will support scanning the code with the camera, shaving some time off of the setup process. Information displayed during the setup process, like icons, brand names, and images, is also improved, making the process somewhat more streamlined.
Scenes
With HomeKit, one of the most confusing and time consuming things to set up are scenes, which allow several devices to work in unison at a specific command. For example, when arriving home, one might want a scene that turns on the air conditioner and turns on the lights, a task that can be accomplished with a Siri command like "Turn on the Home scene."
Scenes are useful, but their setup in iOS 8 is not always clear, especially to users who are new to HomeKit. In iOS 9, scenes are more straightforward because developers can add four pre-defined scenes to apps designed to work with their HomeKit-enabled devices. Pre-defined scenes include Getting Up, Leaving Home, Returning Home, and Going to Bed, and will walk users through setting up their devices for each occasion. Siri will automatically recognize these scenes, so Siri response to Scene queries should improve.
