    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.
