Pair with your Apple TV
1 Add a 4th-gen Apple TV
Open the app and tap Add Apple TV. You’ll be shown a list of all those found on your network. Tap a 4th-gen model and a code will be shown on your TV for you to enter in the app and pair the two devices. Then you’re shown controls.
2 Add an older model
Things are the other way around on older models; the code’s given on iOS, to enter in Settings > General > Remotes on Apple TV. You’ll need the original remote, because leaving this app to navigate with iTunes Remote stops the pairing process.
3 Manage your Apple TVs
After you’ve set up one Apple TV with the app, tap Devices at the top left of the controls if you want to add more (or to remove one if, say, you’re selling it). Tap Edit at the top right, tap one of the Apple TVs listed, and then tap Unpair.
