-
-The Apple TV will automatically turn on if a request is sent to it, e.g., if a button is pressed, something is streamed to it via AirPlay or if current state (currently playing) is accessed. This is how Apple has designed it, and it will cause problems if you are using HDMI CEC. Every time Home Assistant is started, a new request is sent to the device to figure out what is currently playing. When using CEC, this will wake up your TV and other devices you have configured.
-
-So, if your TV is randomly turning on, this is probably the reason. As stated, this is by design, and there is no real fix for it. There's also no known way to turn off the Apple TV via the protocol used for communication. You have the following options:
-
-- Do not use this platform
-- Disable HDMI CEC on your Apple TV
-- Use "fake standby"
-
-The first two points are quite obvious. Fake standby is a concept implemented in this platform that disables all requests to the device and makes it appear as being "off" in the web interface. This will make sure that the device is not woken up, but it will of course not show any information or allow you to control it. It is however easy to turn it on (or off) in the web interface or to use an automation with `turn_on`. To make it more useful, you can write automations that turn it on or off depending on some other device, like the input source on your receiver.
-
-To put a device into fake standby when starting Home Assistant, add `start_off: true` to your configuration.

-Turning the device on/off in the user interface will *not* turn the physical device on/off according to the description above.
