Update: Apple has updated its documentation to reflect the fact that the third-gen Apple TV can do HomeKit remote access, but not automation.
iOS 10 includes a pre-installed Home app from Apple that lets you easily set up and manage smart accessories and automation, which previously required using third-party apps from various developers. There is one important drawback for HomeKit users on iOS 10: you can no longer use the third-generation Apple TV as a hub for automation or remote access.

Instead, you’ll need a fourth-generation Apple TV running the latest software version, tvOS 10, to enable remote access and automation with HomeKit on iOS 10. Alternatively, you can now rely on an always-on and always-home iPad running iOS 10 to also enable remote access and automation.
Finally, remote access in HomeKit on iOS 10 requires users to enable two-factor authentication for the iCloud account used to manage HomeKit. This was not the case during the beta period for iOS 10 or prior, but Apple promoting HomeKit to work with a built-in app with Control Center access calls for the higher security requirement.
For HomeKit users on iOS 9, automation and remote access will likely continue working with third-generation Apple TVs, but new triggers like sunrise and sunset are only available in the latest software updates. The warning signs aren’t very apparent, but keep this in mind before upgrading to iOS 10 if you rely on an older Apple TV for remote access and automation.
For reference, Apple offers these instructions for setting up a compatible device for remote access and automation:
Set up your home hub:
- On iPad: Go to Settings > iCloud and sign in with your Apple ID. Make sure you turn on iCloud Keychain and Home. Then go to Settings > Home and turn on Use this iPad as a Home Hub.
- On Apple TV (4th generation): Set up two-factor authentication for your Apple ID. Then go to Settings > Accounts > iCloud and check that you’re connected under HomeKit.
