Jonathan wants to know how he can find his Apple TV remote. He's frustrated because he loses it all the time. Rich says it's almost always in a seat cushion. The good thing is that iOS11 supports the Apple TV remote natively, so if you installed iOS 11, you have the Apple Remote on your phone.
Another option is to get TILE, it's a tracker that will enable you to find anything you put it on. There's also TRACKR. Does the same thing. Sideclick is another one.
