Product Overview

With built-in Amazon Alexa Voice service, the ecobee4 can listen to your voice commands and respond. Have it set a timer, read you the news, adjust the temperature and more, even from a distance thanks to far-field voice recognition. It also works well with other Alexa devices by supporting ESP so that only the device closest to you responds to your commands. In addition, ecobee4 comes with a room sensor that helps manage hot or cold spots in your home to deliver the preferred temperature to the rooms that matter most. Ensuring comfort when you're home and savings when you're not, ecobee4 pairs with up to 32 sensors and works with Amazon Alexa, Google Assistant, Apple HomeKit, Samsung SmartThings, Wink and IFTTT. Even better, it comes backed by a 3-year limited warranty for peace of mind.
  • SAVE MONEY: Homeowners save up to 23% annually on heating or cooling costs, plus ecobee pays for itself in under 2 years (compared to a hold of 72 degrees)
  • ROOM SENSORS: Place them in the rooms that matter the most and have the temperature balanced throughout your whole home. Measuring both occupancy and temperature, sensors signal your ecobee Smart Thermostat to automatically switch to the right mode for comfort when you're home or for savings when you're not. One Room Sensor included, 2-pack sold separately
  • EASILY INSTALL YOURSELF: It only takes about 30 minutes, thanks to an easy to follow installation guide and an in-app step-by-step walk through. Everything you need comes in the box, including a Power Extender Kit for homes with no common wire (C-wire)

Love it
We moved from your very basic thermostat to the ecobee with an additional sensor and it has been so nice to be able to turn the heat on before we get home so we come home to a nice warm house. The only thing that was slightly confusing for me is I thought you would be able to set the temperature differently for each sensor and you can not. Over all we are very satisfied with our purchase.

    Good until it Died
    I bought the Ecobee 4 in February 2019 and it was installed by my HVAC contractor when my new furnace was installed. It worked for 18 months until August 2020. It would turn on the fan but not send the signal to turn on the AC compressor. The contractor checked the wiring, power, AC compressor unit, etc. and determined the Ecobee 4 was not sending the electrical signal to turn on the AC compressor. The contractor installed one of his thermostats and the AC worked. I understand that products can die but 18 months seems too short.
    Response from ecobeeAug 26, 2020
    That's not the experience we want you to have. Please reach out to support@ecobee.com with your serial number and a copy of the contractor's work order. Happy to help make this right. ecobee

          Getting engaged in our comfort and saving energy.
          Great way to stay engaged in controlling your comfort and saving energy. Can’t wait to talk to Alexa enabled Ecobee4 this summer to ask my Hayward Omnihub to turn on my pool heater. Living in the present, dreaming of our future.

                Love this thermostat
                I’ve had this product for about a month. Installed it on my Rheem heat pump system. It was easy to install, and even easier to set up. My 4yo loves that the Alexa feature will play music for him in the morning. It’s always perfectly comfortable in our house.

                    Wish temp. "set point and holding" font was bigger
                    Temperature set point too small. Please increase font size.
