Provides All-Around Comfort

Be comfortable in the rooms that matter.

Most thermostats only read the temperature in one place (usually the hallway) which can make other rooms uncomfortable. ecobee4 comes with a room sensor to help manage hot and cold spots.

When you place sensors in your favorite rooms, ecobee4 can read the temperature and detect occupancy. That's how it ensures comfort in the rooms that matter

Comes with Amazon Alexa Voice Service built inside.

With Amazon Alexa Voice Service built inside, ecobee4 can perform the many 'skills' that come with Alexa. All you have to do is ask, and watch the blue light pipe on top of the thermostat blink in response. For total hands-free control, it can even hear you from across the room.

Obsessively Engineered

Smarter Home

Engineered to belong in your home.

  • Easy set up

    Check your compatibility and install the ecobee yourself. We can connect you with certified pro installers in your area, too.

  • Built to last

    ecobee thermostats are hardwired, which means your thermostat isn’t relying on a battery or your HVAC equipment to charge itself.

Smart, Really Smart

You have better things to do than to teach your thermostat.

ecobee4 learns your home’s unique energy profile to transform thousands of data points into cost savings.

Features

Ordinary thermostats read the temperature in only one room, but are supposed to deliver comfort in all rooms. ecobee4 remote sensors deliver the right temperature in the rooms that matter most.

If your ecobee4 senses that you are home during your scheduled Away period, or away during your scheduled Home period, it will automatically override your schedule to maximize comfort and savings.

Control your comfort by averaging the temperature of the selected sensors that detect motion or all of the selected sensors in your home, regardless of motion.

As Seen On

With a room sensor and built-in Amazon Alexa Voice Service, ecobee4 is the smart wi-fi thermostat that can listen to your voice commands and respond.

Customers love their ecobee. Let them tell you just how much.

The setup was simplistic (just like the ecobee3 setup) where everything was explained in detail and choices were clearly defined. Made for a flawless setup in my opinion.

David Innocenti

At first I thought I had to touch the mic on the screen, BUT then I realized I could say "Alexa", pause a sec and ask or direct many things...too cool!

Douglas Norway

I get all of the benefits of the Alexa service without having to install Echos all over my house…. It's like having invisible Echo Dots!

Ken Hutchinson

I was impressed with the overall design… The Alexa Voice Service in ecobee4 is an amazing feature. I absolutely love being able to play music, on request, on my thermostat.

Brett Wood

It's convenient to have Alexa built into the ecobee4 and it extends the range I can use Alexa

Bryan Medich

I love that ecobee decided to partner with Amazon to put Alexa in their device. I am a huge Amazon shopper so I am excited that I now have a​ way to control my smart devices using Alexa in my ecobee4​.

Justin Yackee

I think it is a great addition to an already great product. It fits right into the smart home I am working to build. It has great range so I don't have to have an Echo in every room...I like that I can also ask the for the weather as I am getting ready in the morning instead of opening an app or looking at the unit itself. Great time saver. Our kids have also enjoyed asking questions and learning new jokes. It's sold me on the usefulness and functionality of Alexa as well. I am now a fan of Alexa, and a bigger fan of ecobee.
