Use other remotes to control Apple TV
You can use a network-based remote for home-control systems or an infrared remote (commonly known as a universal remote) to control Apple TV.
A network-based remote sends signals to Apple TV through a network so the remote doesn’t have to be pointed directly at Apple TV.
To use an infrared remote, you need to let it learn the signals that the Siri Remote generates.
Use a network-based remote with Apple TV
Before you can use a network-based remote for home-control systems with Apple TV, you first need to add the remote to the Home app on an iOS or iPadOS device. Make sure the remote is turned on and connected to your network.
Open the Home app on the iOS or iPadOS device.
Tap the Add button, tap Add Accessory, then follow the onscreen instructions.
You may need to scan or enter an eight-digit HomeKit set-up code found on the remote itself (or on its box or in its documentation). You can assign the remote to a room, as well as give it a name. The name defines how it’s shown in the Home app and on Apple TV and also how you control it using Siri.
