Roomie Remote provides direct network control of Apple TV all the way back to the first generation. If you experience any issues during the pairing process, restarting the Apple TV and/or iOS device should resolve it.
For Apple TV Gen 4, other guides can be used specific to the app on the device. The Plex Media Guide is provided when running the Plex app for instance.
The content below refers only to the legacy infrared method of controlling Apple TV.
All Apple TV models can also be well controlled using infrared using a supported infrared adapter.
Some rare Apple TVs in the third generation may have trouble waking from sleep (this is a hardware issue and can also be seen with Apple’s Remote app). In such cases it may be useful to send an infrared command to wake the box. Performing a full restore of the Apple TV via USB from iTunes may also help if you encounter that. A common cause of this is the recall of 3rd generation Apple TV units. If you see this issue and it is not resolved by a re-image from iTunes, compare your serial number to the recalled models to replace it.
