Ecobee helps homeowners conserve energy, save money and reduce their environmental impact. Our green automation platform sits at the convergence of energy conservation,  green technology, the networked home and consumer electronics. Our products automate energy conservation, making it easier to save on energy costs without sacrificing comfort.

Great features. Great price.
Ecobee is proud to introduce our latest product: the Smart Si thermostat. Offering another easy, smart, energy solution for your home, the Smart Si delivers the quality, innovation and great features you would expect from ecobee-all at a great price.

The Smart Si is Wi-Fi enabled, so you can make adjustments to your thermostat on the go from your tablet, computer, iPhone or Smart Phone. An easy to read high-resolution color display, sleek buttons, and an intuitive user interface makes it easy to quickly set a personalized program, adjust your settings and create new vacation events whenever you need to.

The Smart Si has a built-in live weather function and uses advanced algorithms so you can be sure your thermostat is always saving the most energy possible. (Now that's smart!) Automatic alerts and reminders notify you when your HVAC equipment is due for service, if there is an equipment malfunction or when it's time to change your filter, so you don't have to worry about it.

Did you know that setting an energy-saving program through your thermostat is one of the easiest ways to reduce your energy consumption and save money? A research study conducted by the ecobee Energy Modeling Team found that ecobee customers save an average of 26% on their annual energy costs!
