FEATURES

The power to choose

SmartThermostat with voice control was the first thermostat in the world with Alexa Built-in, and now it’s the first enabled with Siri. Simply pair with an Apple HomePod or HomePod mini to run your smart home, play and send texts, and find answers to all kinds of questions.

Fine-tune your comfort with voice control

Go hands-free with Siri and Alexa Built-in. Just say, “Hey Siri, set the temperature to 72°” or “Alexa, what’s the temperature in the baby’s room?”

Make intercom-style announcements

You can use your SmartThermostat to send intercom messages to a HomePod mini or Alexa device in another room or throughout the house. Just say “Hey Siri, announce ‘The movie is starting’” or “Alexa, announce ‘It’s dinnertime.’”

The smart thermostat made for music

Listen to your favorite playlists and podcasts on your thermostat with Spotify Connect and Amazon Music. Stream to a Bluetooth speaker for high-fidelity sound.²

What is eco+?

eco+ is a free upgrade for SmartThermostat with voice control. It works in the background to deliver maximum energy efficiency and comfort with minimal effort.

Schedule Assistant

Learns your routine and recommends changes to your thermostat schedule to better match it.

Smart Home & Away

Uses SmartThermostat’s built-in occupancy sensor to automatically adjust the temperature for energy savings when you leave home and restore your comfort settings when you return.

Follow Me

Detects which rooms are in use and adjusts the temperature accordingly for comfort in those spaces.

Feels Like

Takes indoor humidity levels into account to ensure your home is energy efficient and always feels like the temperature you've set, no matter the humidity.

Time of Use

Intelligently preheats or precools your home when electricity is cheaper and reduces usage when it's expensive, saving you money and using cleaner energy.²

Community Energy Savings

Makes slight temperature adjustments during times of peak energy demand in your community, consuming cleaner energy and reducing strain on the energy grid without sacrificing comfort.²

Home IQ

Get a monthly savings report and compare your results to other homes in the area. It’s like an energy audit at no extra cost.

Alerts & Reminders

The app notifies you of sudden temperature drops that could result in frozen or burst pipes and when the system needs maintenance.

Smart Recovery

As SmartThermostat gets to know your home’s heating and cooling patterns, it learns how long it takes to reach your desired temperature. If you routinely wake up at 6 a.m., Smart Recovery will start heating and cooling your home in advance so it’s comfortable when you wake up.

Thermal Protect

Prevents your HVAC system from excessive runtime.

AC Overcool to Dehumidify

This feature will use your air conditioner to lower the indoor humidity to keep you cool and comfortable if you don’t have a dehumidifier.

Supports two-stage heating and cooling

ecobee thermostats are optimized for one or two-stage heating and cooling equipment. Staging control lets you get the level of comfort you like while lowering energy use.

Optimal Humidity

In homes with humidifiers, SmartThermostat regulates indoor humidity to prevent frost build-up on windows.

Fan Dissipation

SmartThermostat automatically runs the fan after a cycle to maximize heating, cooling, and dehumidification.

Free Cooling

In homes with ventilators, SmartThermostat uses outside air to cool down your home instead of the air conditioner when it recognizes the signs of a summer evening temperature drop.

Warranties without worry

Peace of mind that guarantees your product with industry-leading 3-year warranty or 5-year warranty when installed by a Pro.

Wired in

No batteries needed so you’ll never have to worry about replacing them or losing control of your thermostat. Hardwired onto your wall also means you can use your thermostat as a Haven home monitoring hub.
