Ecobee SI Thermostat

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 recent study estimated that the average ecobee homeowner saved 24% on their heating and 21% on their cooling energy costs.*

* Versus the benchmark of leaving their thermostat on hold at 72 degrees Fahrenheit or 22 degrees Celcius.
