Can you use Siri remote to power on/off a receiver?

I have this question too. On my system when I put AppleTV to sleep - it appears to power down the monitor. And it's hit or miss as to whether hitting the same button turns the TV on again - But it does sometimes. A bit confusing, and as a result we hit power on the TV as a rule when powering up now. But never powering down- for that we always use the ATV remote.

Control your TV or receiver with your Siri Remote or Apple TV Remote - Apple Support

Hello,

I've programmed my Siri remote to control my receiver's volume. Is it also possible to program the Siri remote to control the receiver's power on and off?

Thanks!

There is no programming of the Siri remote possible. The technology involved here is called HDMI-CEC and if your receiver supports it the Siri remote will control it. Some equipment has HDMI-CEC turned off by default while others have it turned on by default. There can also be options to control the on/off function. Check the user manual of your receiver to see if it supports HDMI-CEC (some manufacturers call it by other names so watch out). Check to see what options are available for your receiver.
