This thermostat is easy to install and even easier to use. You can control it with just your voice or through the free Ecobee iOS and Android app, and the included room sensor helps keep an even temperature throughout your whole house. You can add more room sensors if you need to. It integrates with a bunch of HVAC devices to get the atmosphere just right and it intelligently adjusts the temperature when you're not home, so you aren't wasting money heating or cooling an empty house. You'll save money on your annual heating and cooling bills, meaning the thermostat will end up paying for itself in two years or less. Be sure to grab one now, before you miss out on the savings.
Depending on where you live, you may qualify for some additional rebates, making this an even smarter investment. If you don't need all of the integration with HVAC devices and accessories, you may be able to get set up with the Ecobee3 Lite and save a little more.
