The 3rd generation Nest Learning Thermostat is thinner and sleeker. It has a bigger, sharper display. With Farsight, it can now show you the time or the temperature you’ve set from across the room. The Nest also saves energy, and can be controlled by Amazon Alexa or Google Home. Nest Thermostats have saved over 4 billion kilowatt hours of energy* so far in millions of homes around the world. In independent studies, the Nest Thermostat saved an average of 10‑12% on heating bills and 15% on cooling bills. In under two years, it can pay for itself.
