    1

    Check wiring and run compatibility

    ~17s
    Shut off power at the breaker and remove your old thermostat's cover. Snap a photo of the wires, then visit ecobee.com/compatibility and enter each labeled terminal. If you do not have a C-wire, ecobee's included Power Extender Kit solves that. You will install it inside your furnace's control board.
    2

    Mount the thermostat and connect wires

    ~16s
    Use the included backplate or trim plate to cover any wall holes or paint mismatches from the old thermostat. Thread the wires through the backplate, push each wire into its matching labeled terminal, and attach the ecobee display until it clicks. Turn the breaker back on.
    3

    Pair SmartSensors to the thermostat

    ~16s
    Pull the plastic tab out of each SmartSensor to activate the battery. Hold the sensor near the thermostat during initial setup — ecobee will detect and pair it automatically. Give each one a room name like "Bedroom" or "Living Room" so it's clear later in the app.
    4

    Place SmartSensors thoughtfully

    ~16s
    Put sensors in the rooms whose comfort matters most at different times of day. A small wall stand is included, or use the adhesive pad to mount on a bookshelf. Keep sensors out of direct sunlight and away from heating vents, both of which fool the temperature reading.
    5

    Build comfort profiles and enable Follow Me

    ~20s
    In the ecobee app, open Comfort Settings and edit the Home, Away, and Sleep profiles. Check which sensors count during each profile — for example, only the bedroom sensor during Sleep. Turn on Follow Me so ecobee prioritizes whichever sensor detected recent motion. Finally, enable eco+ and check whether your electric utility offers an enrollment rebate.

    If your home has one room that always runs cold in winter or hot in summer — usually a back bedroom or a room above a garage — an ecobee thermostat is the single best fix short of replacing ductwork. What makes ecobee different from other smart thermostats is its wireless SmartSensors. You place small disc-shaped sensors in the rooms that matter to you, and ecobee averages the temperature across those sensors instead of reacting only to the hallway where most thermostats live.

    The installation process is similar to a Nest. You turn off power at the breaker, label the wires on your old thermostat, mount ecobee's base plate, and connect each wire to a matching terminal. Ecobee includes a Power Extender Kit for homes without a C-wire — worth mentioning because not every brand does. Once mounted, ecobee walks you through Wi-Fi setup, HVAC settings, and pairing SmartSensors.

    The real payoff is placing the sensors thoughtfully. Put one in the bedroom you sleep in, one in the living room where you spend evenings, and keep one in a often used spot like the kitchen. Then build ecobee's comfort profiles — Home, Away, and Sleep — and assign which sensors matter during each. The Follow Me feature tells the system to prioritize whichever sensor has detected recent motion. So it chases comfort to wherever you actually are.

    Ecobee models also include a built-in Alexa speaker, intercom, and integration with utility rebate programs called eco+. Many power companies give $50 to $125 back for enrolling.
