There are already plenty of solutions for monitoring your power consumption, particularly with Google's relatively recent PowerMeter ecosystem
, but if you want to do things the Microsoft way, Microsoft's Hohm
is about to get third party device friendly. An SDK has been recently released to manufacturers, and we're supposed to expect the first compatible products by the summer. Interestingly, Microsoft has also mentioned that it "might" even get into the game of energy hardware at some point. The end game is to feed back information and control to utilities to be able to load balance energy demand (charging up that fancy electric car of yours overnight instead of at 7pm, for instance), though that sort advance might be as much as a decade out.
