My brother works in HVAC, and I've seen some of the automation available - - the trouble is that the systems aren't intuitive to the user and do very little to think on their own outside of if statements from the sensors.
For technically-inclined individuals, understanding how water, air and gas move is the ticket to a proper disruption. This goes beyond the bandaid fix of a good, intuitive thermostat, and into the circulation of fresh air and overall design of the home.

In this case, there were only a few investment rounds, all of which were reported to be big 'up' rounds, and the (huge) deal was reported to be all cash. All of which suggests that at least the co-founders, and probably at least several others, are going to be very very rich on day one working at Google. Which in turn is not a circumstance very conducive to effective golden handcuffs.
Google is a very big company. I think they are already 50,000 employees in strength. A company so big is not very good at this 'inventing' stuff. There are likely a few engineering oasis somewhere in Google, but the bulk of the company is your ordinary mid level managers, controlling people at grass roots. Their likely goal is to cripple innovation with full force to prevent engineers from looking smart. Add all kinds of pointless bureaucracy.
Spending $3.2B in such ventures in such set ups only leads to a heavily delayed project. Clueless MBA's turned project/product managers enforcing their brain dead ideas in technology areas. Other managers venturing into gold digging, lazy people being elevated as abstract thought leaders etc.
Its best to just to buy something from outside and give them autonomy.
