While it may not look as awesome as the Nest, Sensi’s excellently reviewed smart wi-fi thermostat offers pretty much the same functionalities at less than half the cost, and it even works with Amazon Alexa!

From the couch, the car or the airport lounge, your Sensi thermostat makes it easy to remotely control and schedule the comfort of your home using your phone, tablet or PC. Anytime, anywhere. Use our simple app to quickly create a 7-day schedule to reduce wasteful heating and cooling when no one is home. Your Sensi thermostat is designed to install in 15 minutes or less, even if you’ve never installed a thermostat before. You don’t even need to know what kind of system you have; we’ll figure it out for you right inside our free app. And because it doesn’t require a “C-wire” in most applications, your Sensi thermostat works with most heating and cooling systems (U.S. and Canada only).
