  • Effortless DIY installation. Hassle-free connection

    Even if you have never installed a thermostat before, we've got your back. Using the free Sensi mobile app, simply select the wires that are connected to your old thermostat, and let the app automatically configure the setting that matches your home.

    With clearly illustrated in-app instructions and illuminated easy-click wire terminals, Sensi Touch Wi-Fi Thermostat takes all of the frustration and guesswork out of the installation process. Easily connect to your wireless network in no time, and once you're up and running, you can use the intuitive controls to create a custom schedule in seconds, or set your thermostat to adjust automatically using geofencing for location-based temperature control.

    Designed to work for you

    The Sensi Touch Wi-Fi Thermostat is designed to work with the existing wiring on gas, oil, geothermal, heat pump and radiant heat systems – up to 4 stages of heating and 2 stages of cooling.

    A common wire (c-wire) is required for all system types. For more details on compatibility, refer to Sensi's online compatibility resources or contact our customer support.
