      From across the room or across the country, your Sensi Wi-Fi thermostat makes it easy to remotely control and schedule your home comfort - Anytime. Anywhere. Designed to work with the wires you already have, Sensi does not require a common wire (c-wire) for most installations, so it is compatible with the HVAC equipment in many homes in U.S. Put your comfort on your terms with flexible 7-day scheduling options for quick, custom heating and cooling schedules that can save money on HVAC related energy costs.

      Check your system compatibility before you buy. Compatible wiring is required for installation. If your wiring is not compatible, consult with a contractor for installation assistance.
