Without going into the hyperbole surrounding the Nest thermostat, the simple explanation is that it is the home heating and cooling thermostat-equivalent of a smartphone. It has a beautiful graphical user interface, and simple controls. It can sense your presence in a room, and adjust the heating/cooling to accommodate. It learns your daily routines and adjusts its behavior to save energy and money. It’s even internet-enabled, and there are iOS and Android apps you can use to run it when you’re away from home.
