The Sensi Touch Wi-Fi smart thermostat puts comfort control at your fingertips whether you are at home or on-the-go. Just a tap of the easy-to-use touchscreen display or free mobile app lets you remotely access, change or program your home temperatures. Anytime. Anywhere.

Savings vary based on equipment type/condition, insulation, climate & temperature adjustment size/frequency. **Based on survey results of 2120 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. ***Does not work with electric baseboard heat and some other systems. System requirements for mobile app: iOS - 10.0 or above Android - 4.2 or above (5.0 or greater to use the Geofencing feature).

I believe I have a supported thermostat with a common wire (C wire). Does this thermostat require wifi to operate? Quite often in Florida I turn all sensitive electronics off (including wifi) because of thunderstorms. Does this thermostat allow all the traditional functions at the thermostat itself, such as, cool, heat, raise/lower temp etc... without using a mobile app which is dependent on wifi? In other words is it a simple touchscreen at the thermostat and no requirement for the app/wifi? I understand the app might add functionality, but I'm more interested whether or not it will still function as a traditional thermostat (but touchscreen in this case)?

Battery Life

Our first set of batteries lasted about 2 months. The last 2 sets lasted about 2 weeks. When the batteries die the thermostat does not work at all and shows offline. This is at our camp and in the extreme cold we have no furnace at all and have to drive there to change the batteries. Does anyone else have this issue?
