  • Fabulous Product Easy to use

    from Waterloo, Ontario on October 28, 2019

    This is an easy to setup and use thermostat, mobile app works great. Integrates easily with Alexa. Web interface contains a lot of helpful information on usage, time of day etc. You can manage a few thermostats from the same account, which is nice if you have a home, cottage etc.

  • Horrible Customer Service - NO HELP!

    from Ontario on July 17, 2019

    I am incredibly disappointed in this company and their (non-existent) help in this matter. I originally called because my ex (who does NOT live in my house) suddenly had access to MY thermostat that I had put an access code on so he could no longer control the settings. It was set up in MY name, MY email address and MY cell #...I'm still waiting to hear how this happened???? I used random number he would never be able to guess, yet he someone got access and changed the access code and had access to the thermostat in MY house!!???!!! All they did was ask questions (like did I still have the receipt or to send a pic of the back!) but NEVER once gave me an answer!!!! I have since changed out the ecobee as you were no help in my getting access to it again.

  • Easy to setup and use

    We have 2 of these in our new home and absolutely love them. They were easy to setup after installation, with no manual needed. I would 100% recommend this product.
