Performance: One of the best things about this smart thermostat is the fact that it's highly accurate! Emerson is one of the leading HVAC companies in the world, manufacturing high quality devices like this that have only a slim margin of error for the readings. If the thermostat says it's 72 degrees, it will be off by no more than 1 degree--a statement not many other thermostats can make.

Installation of this bad boy is a breeze! You'll find that it takes less than 30 minutes to remove your current thermostat, install this one, and set it up to start controlling your HVAC system. The step-by-step instructions are easy to follow, and it's incredibly simple to connect the device to your Wi-Fi, download the app, and get working.

One note: a number of users have commented on the Sensi app, specifically the connectivity/server issues. If your phone can't connect to the thermostat, it's not because you have spotty Wi-Fi, but because the Sensi server is having troubles.

Features: The thermostat is controlled via the Sensi app, which some have found slightly difficult to use. The app gives you access to a wide range of features, but the navigation makes finding those features challenging for those who are less than tech-savvy.

The device is compatible with over 90% of HVAC systems, including geothermal, gas, radiant heat pump, electric, and more. For cool-only or heat-only systems (like hot water heaters), you will need a C-wire to make the thermostat work, something not all homes have.

The thermostat is compatible with Amazon Echo, which gives you voice control over the device. Definitely makes it easy to adjust the temperature settings hands-free!

Price: At just over $110, this is a well-priced thermostat with plenty of smart features to make it worth your while. If you can get past the connectivity issues, you'll find that it's a handy device to install in your home.
