Smart Thermostat, 2nd Generation, Works with Alexa, Silver V552677

The Nest Learning Thermostat programs itself, then pays for itself. It learns from you and your home, programs itself automatically and helps save energy when you’re away—and you can control it using your phone, tablet or laptop. In independent studies, the Nest Thermostat saved an average of 10–12% on heating bills and 15% on cooling bills. Based on typical energy costs, that means it pays for itself in under two years.
