It can be used as a TV clock show Time
It can also display smart accessories at home
Make up for the lack of home apps in appTV
It can also monitor all cameras in real-time(i only test 4 cameras)
Some users asked me why its not possible to select a home like on iOS. After repeated testing and research, I found that HomeKit is unable to retrieve all the homes under the account, it can only retrieve the homes where the Apple TV is a hub or Apple TV under the current home. Its possible that Apple has done this intentionally. After all, a TV cannot exist in some families at the same time.
if you control the accessories in other way, the accessories status will not Real timeupdate at real time. i think it is tvOS bug.
but when you control the accessory with tv siri, the accessory will change at real time
