    I have a new Apple TV that I set to never sleep, but several times now it's decided to go to sleep anyway at some point. It has overnight each of the last two nights, for example. It's also set to not control/be controlled by the TV, so it shouldn't be a matter of sleeping when the TV goes off. Rebooting hasn't changed the behavior. Has anyone else seen this or have suggestions as to how to fix it? I have a second new Apple TV in the other room and it's stayed awake without any problems.

    Very strange, the only thing I could think to suggest off the top of my head would be doing a restore and setting it up again.

    Hmm... I might have figured it out. I think the issue was that although the Apple TV was set to not control the TV through CEC, the TV had a setting to send "turn off" signals over CEC when the TV was turned off, and the Apple TV listened to those signals and put itself into sleep. I changed that setting on the TV, and I'll see if the Apple TV stays awake now.

    Good catch, hopefully that'll sort it out.

    Yes, it did. It's stayed awake ever since I made that change.

    wow this may be it. I was trying to find CEC on my LG to see what to turn off and I see on the LG it is called Simplex. I only found option to turn on or off the simplex so I turned it off. Before I found that I turned TV off and sure enough even though I turned off connection in Apple TV to not be connected turning of LG turned Apple TV of annyway. will be interesting to see if my Apple TV stays on now!

    now I'm waiting to see if this fixes it for me. Two of my lights setup in automations didn't come on so I went looking and found the AppleTV was off. It was/is set to never sleep so it can act as the Homekit hub. I found the Simplex setting to be on in my LG TV menu. I turned it off so we will see, thanks for the tip. I do know after changing that my TV no longer turns on and changes to the correct HDMI when I hit menu on the ATV remote but thats fine, I can do that part.
