Hey, I just registered to say "thanks" too!
I'm from Russia, so sorry for my English..
Yesterday just bought 3 Yeelight white bulbs for living room general lightning.
Really thinking about buying another couple of colorful bulbs or, maybe, LED strip for TV backlighting.
Awaiting for GA integration
(Yes, I know about IFTTT, but... you know too)
One question: will it be native integration or ["hey, Google, let me talk to Yeelight...", "hey, Google, ask Yeelight to...", etc.]?
