I was digging around in the settings for my Shield and discovered there is a setting you can enable that says it allows you to use Google Assistant while the TV is off. Does anyone know how this would actually work? Surely with the TV off there's no way to hear the audio responses? Has anyone set it up?
The 2017 controller is the microphone. I leave mine on my coffee table so it can hear me. When you say "ok Google" the shield will glow green as you speak and carry out any tasks you have, like turning on a light if you have a smart home. The TV won't turn on. It's basically a Google home with out any audio response.
"Ok google, turn on the TV" also works if you have HDMI set up to do that.
