After signs of the proverbial switch flipping surfaced this weekend, Google Now's Nest integration is live. You'll need to authorize both the Google app and its voice control separately, but once you do, a simple "change the temperature to 74 degrees" is all you'll need to make the adjustment. What's more, a new card will show up letting you know when the Nest is hard at work to make your abode comfy during that evening commute. In fact, it'll make the adjustment automatically based on your phone's location. The new feature plays nice Google's software on both Android and iOS, so smart thermostat owners can opt with either one. If you run into issues, Nest has a handy guide that should help.
