Affordable and Easy to Set Up and Use

I was looking for a thermostat that was simple to install, easy to program and operate, had a backlight, had smart features but also was affordable. This Sensi unit met all the qualifications. Making a connection to WiFi was easy and the app is very simple to use. I like being able to turn it on or off or change the set point using my phone. The display is easy to read as well. For our household, this Sensi thermostat is the perfect blend of technology and simplicity.

Easy to use and works great

I am very satisfied with my Sensi Smart Thermostat. The installation process was quick and easy, and it has worked perfectly since day one. The app is very user-friendly, and I love being able to control the temperature from my phone anytime. The system keeps my home comfortable at all times, and I have noticed better energy efficiency with my air conditioning. In addition, the thermostat has a modern and elegant design that looks great on the wall. I would definitely recommend Sensi to anyone looking for a reliable and easy-to-use smart thermostat.

Liked it so much I got a second one

Lost our first one exactly like this in a house fire. After we rebuilt I demanded we get another because I liked it so much. Love that I can control it from anywhere on the app on my phone. I get an energy discount from my electric co just for having this thermostat!
