The Sensi™ Touch Smart Thermostat puts comfort control at your fingertips. At home or on the go, the easy-to-use interface lets you adjust your thermostat with just a tap.
Check your system compatibility before you buy. Compatible wiring, including a c-wire, is required for installation. If your wiring is not compatible, consult with a contractor for installation assistance.
SAVE ABOUT 23% ON HVAC ENERGY: By adjusting the temperature using flexible scheduling, remote access, and geofencing, Sensi customers saved about 23% on HVAC energy usage. Energy savings calculated by comparing operation time for a nationwide sample of Sensi users with temperature adjustments averaging 4° vs. users with no adjustments. Savings vary based on equipment type/condition, insulation, climate & temperature adjustment size/frequency.
MOST PEOPLE INSTALL IN 30 MINUTES OR LESS: Use the built-in level, illuminated easy-click terminals and step-by-step app instructions for a quick installation. Skip any extra work painting or patching the wall thanks to the standard thermostat size. Based on survey results of 2,120 respondents that purchased and installed a Sensi thermostat in 2018, approximately 70% reported installing in 30 minutes or less. Adding a common wire may impact installation time.
