The more we grow, the greener it gets.

We invented the Smart Thermostat and kicked off a wave of innovation that has changed the way millions of people heat and cool their homes. That was just the beginning.

Transforming everyday life and making a sustainable difference since 2007.

So far ecobee thermostats have delivered over 20TWh of energy savings.¹ That’s like:

  • Taking all the homes in Los Angeles off the grid for one year
  • Keeping 14.1 million tons of CO2 out of the atmosphere
  • Charging 1.7 trillion smartphones
  • Removing 3 million cars from the road for a year

    A better tomorrow

    We empower customers and support communities.

    • The Donate Your Data program gives customers the option to share their anonymized data with energy scientists.
    • Researchers in Indiana used ecobee data to show smart thermostats could save the state up to $2.3 billion.


We keep thousands of our thermostats out of landfills and reduce e-waste by repairing and reusing them.

Energy conservation
Simple changes add up to tons of impact.

The average household in the United States produces 7.5 tons of CO2 per year and over half of the energy used in most homes is for heating and cooling.³

Our ENERGY STAR certified smart thermostats and sensors have been invited into millions of homes because they guarantee lower energy costs by up to 26%* percent. That translates into an average annual saving of $234 per home, per year⁴ and billions of kWh of energy savings for ecobee users.

Sustainability built in
Engineered to last in your home, not a landfill.

We want our devices to become fixtures in your home. That’s why we future proof them with enough processing power to be useful for years to come. For example, eco+, our next-generation thermostat software, works with all ecobee thermostats released since 2014.

A better tomorrow
Building a healthier planet and society

Sustainability is more than energy conservation. We lighten our environmental impact and social impact by using more recycled plastics and materials that are ethically sourced in our products and wrapping them in fully recyclable packaging.

One in three families struggle to pay their utility bills. To help families fighting energy poverty, we have partnered with community housing organizations, cities, NGOs, and utility providers to donate hundreds and subsidize thousands of thermostats.


Welcome to the ecobee Home.

A home that brings harmony to homelife.
As soon as you step out, the ecobee Home can adjust the temperature for energy savings, turn on cameras, secure exits with door and window sensors, and set the lights to make it look like someone’s home.

That helps the community.
To help keep the power flowing during a summer heatwave or winter cold spell, with eco+ ecobee thermostats can automatically adjust the temperature slightly when demand peaks. You’ll be rewarded for pitching in with a rebate from your utility provider.

And is ready for what lies ahead.
Experts say the world must be carbon-neutral by 2050 and that energy efficiency will play a key role. Our eco+ thermostat software intelligently pre-heats or cools the home when power is less expensive and cleaner. This is one way we are using technology to help bring about a brighter future.

The most affordable and cleanest energy choice we can make is not to waste it.
