The app is preloaded onto iOS 10 and watchOS 3, and allows you to see all your HomeKit devices and perform actions on them. Furthermore, a feature called ‘Scenes’ lets you adjust multiple devices at once. For example, you could turn off all the lights in a room and close your window shades with a particular scene.
Continuing a the theme throughout its iOS presentation at WWDC, you can also adjust your HomeKit hardware right from your lockscreen, as it’s integrated right into the Control Center.
Apple TV plays a big role too – it can sense when you’ve entered the home network, acting as an entry point for controlling your devices.
Home seems like a simple and elegant solution for managing your devices, and much better than needing to download a separate app for each piece of HomeKit hardware.
