If you have issues creating automations or controlling your HomeKit accessories when you're not home, follow these steps:
1. Make sure that your Apple TV or iPad is:
- Connected to the Internet and on the same Wi-Fi network as your other iOS devices during set up.
- Updated with the latest version of tvOS or iOS
- Signed in to iCloud with the same Apple ID with two-factor authentication enabled.
2. Make sure that you can control your accessories in the Home app on your iOS device. Open the Home app and turn on a light or change the temperature.
3. Make sure that your device is set up as a home hub:
- On your Apple TV, go to Settings > Accounts > iCloud and make sure that your Apple TV shows HomeKit as Connected. If you don’t see HomeKit, then your Apple TV isn't connected as a home hub.
- On your iPad, go to Settings > Home and make sure that Use this iPad as a Home Hub is turned on.
5. Wait a few minutes. If you still need help, sign out of iCloud on your Apple TV, then sign back in. Go to Settings > Accounts > iCloud.
If you have an Apple TV (3rd generation)*, you can control your HomeKit accessories in the Home app while you’re away from your home. To change user permissions, create automations, or stream HomeKit-enabled cameras remotely, you need an Apple TV (4th generation). If you add an Apple TV (4th generation) to a home that has an Apple TV (3rd generation) set up, the Apple TV (3rd generation) will stop being used for HomeKit remote access.
