Needs to be through Google Assistant

I did not test on Google Home, but we had previously Now integration so basically telling Google Now "Start sleep tracking with Sleep" will start sleep tracking, also we support the standard start workout fitness intent and on Android Wear you can use "Start sleep tracking"..
And/Or Google Assistant
