Plus, it works with Alexa, Google Assistant, and Apple HomeKit, making voice control a breeze.
Energy Star Certified – Saves You Money
This thermostat is Energy Star certified, meaning it’s designed to optimize heating and cooling efficiency. The app provides energy usage reports, so you can see exactly how much energy you’re using and get recommendations on how to save money on your utility bills.
Flexible Scheduling for Personalized Comfort
With 7-day programmable scheduling, you can set custom temperature schedules to match your daily routine. This means no more forgetting to adjust the thermostat when leaving home—Sensi does it for you.
C-Wire Required – But There’s a Workaround
The Sensi Touch ST75 does require a C-wire for installation, which can be a hurdle for some homeowners. However, if your current HVAC system doesn’t have a C-wire, you can use an adapter or consult an HVAC professional for a workaround.
Geofencing for Automatic Adjustments
With the geofencing feature, the thermostat can detect when you leave home and automatically adjust the temperature to save energy. When you return, it brings the temperature back to your preferred setting—super convenient for busy households.
Smart Alerts for Peace of Mind
The Sensi app sends real-time alerts if your home’s temperature or humidity levels go outside of safe ranges, helping you prevent potential HVAC issues before they become costly problems.
