  • 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..

    With Alexa, fulfill everyday tasks with a simple command.

    Imagine you’re throwing a last-minute dinner party. Simply ask your ecobee4 to walk you through each step out loud – from finding the right recipes to the ideal music playlist.

    Designed to be seen and heard.

    ecobee4 has embedded microphones with far-field voice recognition and a speaker engineered for clear voice and full sound. It’s the smart thermostat that looks at home on your wall – that you can hear and speak to from across the room.

    Save an average of 23%* in heating and cooling costs each year.

    Smart Home/Away can automatically enable the right mode for energy savings when it senses no one is home.

    Free energy reports show you how much energy you’ve conserved each month and provide insight into your heating and cooling equipment.

    Engineered to belong in your home.

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

    Great Thermostat Review by James
    Great Thermostat

    But unless you don't already have Alexa, I'd skip it and get the Ecobee 3. If you get the 3 and wait until you can score an Echo Dot for $29.99 on sale, you'll save money and get more. The Alexa on this isn't 100% functional like an Echo Dot is.
