Amazon Smart Thermostat – Save money and energy - Works with Alexa and Ring - C-wire required

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.
