The Nest Thermostat E is ideal for homeowners who want a smart thermostat that blends into their decor while saving energy. It's perfect for setting a comfortable home temperature for your family's return after work or school.
You might expect a programmable thermostat to just control temperature, but the Nest Thermostat E becomes a tool for understanding your energy usage. It learns your schedule and adjusts to Eco Temperatures when no one is home, so you save without thinking about it. The frosted display sits low-glare on your wall, easy to read from across the room.
Through the Nest app, you can change the temperature from your bed or from the office. It integrates with Alexa and Google Assistant for voice control. The Home/Away Assist uses sensors to know when you leave, automatically adjusting to save energy. This gives you real peace of mind that your home is efficient and comfortable.
