Apple HomeKit guide details setup and use, remote access via Apple TV

The guide notes that HomeKit works with any iOS 8.1 device, and certified accessories. To pair an accessory, users must find its seven-digit setup code and enter it into the gear maker's custom iOS app. Some apps should allow accessories to be grouped together into homes, rooms, or scenes.

From that point on a person can use both apps and Siri commands to control individual accessories or assigned groups. Saying "turn off the lights in the living room," for instance, might be used to shut off several HomeKit-ready lamps at once. Significantly, Siri cannot be used to unlock a door.

Remote access to a HomeKit network requires a third-generation Apple TV with v7.0 firmware. As long both the Apple TV and the iOS device are signed into the same Apple ID, Siri commands will work anywhere with Internet access.

HomeKit support has been present in the Apple TV firmware since v7.0, even though Apple has not publicized it until now. On Tuesday, Elgato announced it in the requirements for its new Eve series of environmental sensors.

The guide also addresses tasks such as resetting accessories, troubleshooting, and what to do if an iOS device is lost or stolen.
