Amazon Smart Thermostat is ENERGY STAR® certified. According to EPA estimates, ENERGY STAR certified thermostats save an average of $50 on yearly energy bills. Check with your energy provider about available energy savings rebates to save on your purchase. Plus, eligible customers can enroll in ongoing energy savings incentives with their energy provider to keep saving all year long. Get information in the Alexa app.

So Smart You Don't Have to Think About It

Alexa does the programming for you, automatically adjusting the temperature to suit your preferences. The thermostat can even be set to your preferred temperature if Alexa has a hunch you’re home, away, or asleep.

Link the Amazon Smart Thermostat to an Alexa-enabled device at home, and you can control your HVAC system with your voice. Not at home? Use the Alexa app to manually adjust the temperature or set a schedule, even on the go.

Smart upgrade - Amazon Smart Thermostat is an easy way to switch from a traditional thermostat and help reduce energy usage.
Save money - After purchase, Amazon will send you an email with details about rebates that may be available from energy providers in your area. Explore rebates above.
Save energy - According to EPA estimates, ENERGY STAR certified thermostats save an average of $50 on yearly energy bills.
Automatic comfort - Alexa can do the programming for you, updating the temperature to keep you comfortable.
On-the-go control - Let Alexa set the temperature, or set it yourself from anywhere with the Alexa app.
You can do it - The Alexa app will guide you through the installation process, but customer service is always available.
Reliable - Made with Honeywell Home Thermostat Technology and backed by 130 years of experience.

Follow the Guided DIY Installation

You can install Amazon Smart Thermostat on your own by following the step-by-step instructions in the Alexa app. If you need any help, contact 24/7 customer service via phone, chat, or email.

If you prefer, you can also hire Amazon Home Services or a local HVAC tech to do the installation instead.

We Want You to Know

Amazon Smart Thermostat doesn't have a speaker or microphone. For voice control, use a compatible Alexa-enabled device, like an Echo (sold separately), or the Alexa app.

Before purchasing, use the link “check compatibility” to see if the thermostat will work in your home and to determine if your home needs a C-wire power adapter.

Amazon Smart Thermostat requires a C-wire or a power adapter kit. Use the compatibility checker to see if your home has one already. Guided installation instructions are included in the Alexa app.

How do Hunches work?	When your phone leaves your home area and nobody interacts with Alexa for a while, Alexa might have a hunch nobody’s home. If no one interacts with Alexa for a while at night, she might have a hunch everyone is asleep. When someone interacts with Alexa or uses smart devices, she can tell that someone is home. Alexa learns from your daily interactions and improves over time. You can also help Alexa know when you go to bed or leave home by saying, “Alexa, goodnight.” or “Alexa, I’m leaving.”
