Is there a sleep timer hiding in my new Apple TV?

There isn't a setting to put the Apple TV to sleep whilst being used to play content if that's what you mean.

TThe ATV will sleep automatically after a period of inactivity. So if you enable sleep on your tv, the ATV should go off shortly after...

Put your Apple TV in sleep mode - Apple Support

• Apple TV (4th generation): With your Siri Remote or Apple TV Remote,^* press and hold the Home button for five seconds. Then Select Sleep Now. You can also go to Settings > Sleep Now.
• Apple TV (3rd generation and earlier): With your Apple Remote(aluminum or white), press and hold Play/Pause for five seconds. You can also go to Settings > Sleep Now.

Unfortunately that puts it to sleep immediately, I believe the OP wants to put it to sleep after say 60 minutes and maybe even once they've gone to sleep themselves.

Samantha, If you have any suggestions that you think might enhance the Apple TV you can send Apple your feedback here

Not sure I just understand. I turn the sleep timer on my tv - say 60 minutes. My tv will turn off after 60 minutes and when I wake up the ATV is sleeping?

From Apple's iBook on the subject (page 27)

Maybe I'm misunderstand the OP here, but...

If the OP puts on a TV show app such as NOW TV and turns (say) the Discovery channel on and then falls asleep after 30 minutes, the Apple TV (and the TV unless it's own timer is set up independently) will play all night consuming power and potentially eating up any download allowances in place. I believe the OP wants to start watching, knowing that if they fall asleep that the Apple TV will turn itself off and turn the TV off too at the 60 minute mark.

The Apple TV settings as they are will not do this, the settings you refer to only put the TV to sleep if it is idle for the preset time.

If the ATV is going always to go on to the next item then this would be the case. I assume it doesn't do so with single items like films, but I suppose it's likely to with TV episodes.

TV episodes from an app like NOW TV for example - yes, TV episodes from iTunes over the internet - no, TV episodes from iTunes via home sharing - yes, so it's a bit of a mixed bag really.

I have turned my TV on on some occasions (where I'd turned it off without turning the Apple TV off) to find a message on screen from some app or other (I don't recall which) that suggests that after a number of hours an online streaming service may stop the stream, I don't know if they all do it, I suspect not, nor do I know after how long, but it is certainly more than just a few hours.

Works like a charm. Thanks!

Works like a charm. Thanks! I set the TV timer and when it turned off the Apple TV shut off after 15 mins.
