I literally took it out of the box and had it installed within 10 minutes and the app downloaded and link in another 5-10 minutes. Anyone can do this and the ability to have better control over the thermostat, both summer and winter, will save me some real money.

The app is great, and even provides data on how much time heating and cooling ran each day over the last week and well as monthly numbers. I also like that the display is big, and easy to read. It also changes color based on if heating is running, AC is running or nothing is running. It even has a backlight around the outer edge, though I don't use that feature. One of the nicest things it supports is that you can adjust the temperature and humidity it displays up or down if it's off a little bit.The app is designed to support multiple thermostats, though I only have one." — Chuck from DallasAmazonAn Ecobee smart thermostat with over 9,000 5-star ratingsRating: 4.5 out of 5 starsThe Ecobee3 Lite smart thermostat promises to help you save up to 23% on heating and cooling costs every year (compared to a hold of 72 degrees Fahrenheit), and works with Alexa and Google Assistant as well as iOS and Android devices so you can control it from anywhere.

We had used others in the past, but heard good things about ecobee. We love this one! We can control it easily with Alexa, for instance we love sitting on the couch and saying “Alexa, turn the heat up a degree” if it’s cold and we immediately hear the heat kick on. Easy to control from phone too which is nice for making adjustments while away from home. We would highly recommend this product." — AlyssaAmazonThe ultra-popular Google Nest Learning thermostatRating: 4.4 out of 5 starsThe fourth generation of the Google Nest Learning thermostat comes in five colors and works with Google Assistant and Alexa.
