What kind of functionality are you thinking of new channel
Is the functionality already available at a service like IFTTT, Alexa or Google Home?
Yes, at least turning on/off the Xbox is available at Google Home
What functionality would you like to propose:
When I say “time to game”, turn on TV, switch TV to Xbox, turn on Xbox
When I have a new achievement blink lights / play music
When Xbox starts turn off music / dim the lights
Remind me to claim new Xbox gold games
