    1. BEST SELLER: Amazon Smart Thermostat – ENERGY STAR certified

     

      View price on Amazon  

    • Clever upgrade - The Amazon Smart Thermostat makes it simple to replace a conventional thermostat and contributes to energy conservation.
    • They are saving energy - The EPA estimates that ENERGY STAR-certified thermostats reduce annual energy costs by an average of $50.
    • Automatically cozy - Alexa can program the temperature changes to keep you comfortable.

    There is neither a speaker nor a microphone on the Amazon Smart Thermostat. Use the Alexa app or a compatible Alexa-enabled device, such as the Echo (sold separately), for voice control. Use the "check compatibility" link to verify if the thermostat will function in your house before you buy it and determine whether you need a C-wire power converter. The Amazon Smart Thermostat needs a C-wire or a power adaptor kit. Use the compatibility tester to find out if your house already has one. There are guided installation instructions in the Alexa app.
