The Nest Thermostat E makes saving energy simple, with a beautiful, subtle design.


  • New industrial design. The Nest Thermostat E moves away from the prominent look of the Nest Learning Thermostat and replaces it with a more subtle design, highlighted by a white exterior ring and frosted display.
  • Frosted display. The frosted display is designed to blend into your home. It achieves this effect with special display technology that lets light out but doesn't let light in. When the frosted display is off, the screen is grey. When it's on, it displays soft text and images that are designed to be easy to see and read with a slight glow. The frosted display uses an ambient light sensor to share information at just the right brightness.
  • Scheduling made simple. The Nest Thermostat E comes with a pre-set schedule, which enables customers to save energy right out of the box. This can be easily managed directly from the Nest app. Or it can learn your schedule, just like the Nest Learning Thermostat. It's ENERGY STARR
  • The core experience of the Nest Thermostat E includes features that people have come to expect from previous Nest thermostats.
  • The Nest Thermostat E turns off automatically when it detects nobody is home, to help save energy.
  • It's easy to change the temperature from anywhere with the Nest app from a phone, laptop, or smartwatch, and even with popular voice assistants such as Google Home or Amazon Alexa.
  • Through the Works with Nest program, additional connected products, such as ovens and lights, integrate with the Nest Thermostat E to add more comfort and convenience.
  • Nest sends alerts if the heating or cooling system needs attention, so customers can act before it breaks.
  • The Nest Thermostat E is easy to install, with most customers installing them in 30 minutes or less. In addition, there are more than 20,000 certified Nest Pros in the U.S. available to install Nest products.
