Amazon Smart Thermostat is ENERGY STAR® certified. Easily switch your traditional thermostat and help reduce energy usage. For on-the-go comfort, let Alexa set the temperature, or set it yourself from anywhere with the Alexa app. Amazon Smart Thermostat is compatible with most 24V HVAC systems (like conventional force air, heat pump, radiant boilers, etc). It does not work with 110-240V HVAC systems (like electric baseboard heat). Smart Thermostats require a C-wire (most homes have one) or a C-wire adapter kit (sold separately).

Smart upgrade- Amazon Smart Thermostat is an easy way to switch from a traditional thermostat and help reduce energy usage
Save money- ENERGY STAR® certified thermostats are required to save an average of 50 on yearly energy bills-¹
Automatic control- Alexa can do the programming for you, updating the temperature to keep you comfortable
On-the-go comfort- 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

What Customers Are Saying

The smart thermostat has a mixed reception. Many found the installation easy, especially with the Alexa app, and praised the voice control integration.

Great product

Would Recommend

Easy install of you know what you are doing. The first 2 installs went well, the third one i needed some help. This particular unit is for a vacation rental and it now allows us to control what renters can set it to a week a giving us the ability to change settings ahead of time when we come to visit.

So surprisingly bad

Would Not Recommend

1. It wasn’t following the temperature schedule. After searching online and trying lots of dumb things, I changed the time zone from ET to ET. Yeah. Then it worked better, but not always. 2.
