Nest opens its API, starts Works With Nest program for our thermostat pick

With its new Works With Nest program, some cars, activity trackers, and garage doors (and other things) will be able to give Nest thermostats more information about when you’re home or away or when you’re awake or asleep and adjust energy use accordingly. The Nest API is also now open to developers who want to incorporate home, away, and usage data into their apps. More details are in our Smart Thermostat guide.
