AppleTV 4 keeps waking up

I've tried all of the suggestions and none of them work. Also, holding down the pause play button does nothing. I have two ATV4's and only one of them does this.

very annoying

Yes I finally found others who are having this problem. No harmony remote here. My Apple TV will randomly just turn on and start playing or if i am just sitting at the menu screen idle it will start playing. It is usually netflix. It is playing in the background. It is definitely an issue with the Apple TV. It drives me nuts... Still no word from Apple yet on this issue?

If you force quit the apps before sleeping, does it still wake up? See https://help.apple.com/appletv/#/atvbbcec4f4e for how to force quit.

Are you using any form of AirPlay when this happens?

Some of the posts in this thread suggest setting the Sleep After time. Have you done this?

Yes if I force quit all apps so there is nothing running it does not happen ever.

I have switched the Sleep After time to 15 minutes but I was watching Plex earlier and literally just hit the menu button to go backto the main screen because I had to make a phone call. 5 minutes later it started playing and sound coming through the speakers even while the app was running in the background. You cant even make the Apple TV do that... When you switch an app the app stops playing right away. Why does it keep playing in the background. All this is related... it seems to me....

One possibility that hasn't been mentioned is that ATV will respond to HDMI-CEC commands fro the TV. Could the TV or TV remote be sending a Play command?

Also, when you want to leave an app, do you hit Pause first, or do you actually leave it playing in the background? Since tvOS is more closely based on iOS, continuing to play might be expected behavior, since that's how iOS works with music apps e.g.

No TV remote in the picture.. in fact our TV remote doesnt even have batteries... we dont need it since the Apple TV will turn our TV on and off...

As for playing in the background. I cant even make Plex or Netflix play in the background as it is. If I am watching a show on plex and switch the application it stops playing. Same for netflix. I didnt think I could play plex, netflix and all these other things in the background as it is so if they start up while they are in the background and I am at the menu screen there is obviously a problem.

BTW I cant thank you enough for your help everyone. I just cant figure this one out!

I agree that, when you switch applications, the one you were in appears to stop playing. But, if you don't explictly pause it, it may be in a state where it is still trying to play. Remember that tvOS is very similar to iOS now, so apps are independent programs and can run in the background. I had a similar problem with a Sony Google TV, where the YouTube app would wake up and start playing the last video it had played; I had to force quit it every time to stop this. Waking from sleep is harder to explain, of course.
