Product Overview

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. Sensi mobile app guides you through each step of the DIY installation process. A common wire (c-wire) is required for all system types. Refer to our online compatibility resources on our website to make sure Sensi thermostat will work in your home. Once your Sensi thermostat is up and running, you can let your location automatically adjust your temperature settings with geofencing or use the intuitive controls to create a custom schedule, to save about 23% on your HVAC energy usage. Energy savings calculated by comparing operation time for a nationwide sample of Sensi users with temperature adjustments averaging 4° F vs. users with no adjustments. 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).

Best purchase I made this year
I love my new thermostat. It was very easy to install. I did it myself. I had trouble connecting to the wifi at first because have 2 networks in my house but I figured that out. It has worked perfectly and I love being able to change the schedule from my phone.

I love this item! It was the easiest thermostat I ever installed, and the features are great. I can control the home temperature from my phone anywhere. You even program it on the phone app. I'm going to buy a second one for the downstairs unit.

Awesome purchase!
I first purchased the Sensi Touch Wifi thermostat because I was having furnace issues. Turns out the furnace had to be replaced but i kept the Sensi and I’m glad I did! Love the Wifi functionality and the furnace installer researched it and was able to scrap my old manual humidistat control and operate the whole house humidifier through the Sensi! Once again....AWESOME!

      Make Sure You Have Long Wires
      I bought 2 of these thermostats to go upstairs and downstairs in my house. The installation was fairly quick upstairs, but downstairs proved to be more challenging when it came to the wire length. I needed more slack from the wires to get them all connected properly in the terminals. After fiddling with that for a bit I was able to get them connected. Connecting both devices to my wifi and controlling them has been a breeze and I haven't had any connectivity issues. There are some routers that aren't compatible so I recommend you verify this before buying.

        Fixed my battery dependency!
        So this is my 4th thermostat. The one that came with the house was that old mercury one. I replaced it with a programmable battery one some time later and a few years after that it was replaced with a non programmable one when I replaced the entire AC system 3 years ago. I bought this one since it had a Cwire which I had mine already ready to connect to both the furnace and the thermostat. The installation guide was super easy. Also, it fit right into the frame of the previous one so it looks like it came with the unit. The only drawback is that the screws it came with were pretty small compared to the last one, but I ended up using the old ones and it was perfect anyway.

          We Love This Thermostat
          We used to have a Nest thermostat. But for some reason, it took the thermostat 1.5 hrs to cool our 1,400 sq townhouse down 1 degree. We called our HVAC guy and he said it was the thermostat. We tried three more Nests and they all did the same thing. We went back to Home Depot and saw the Emerson Sensi Touch Thermostat and liked the look of it. Installation was very easy and it works great! I love being able to turn the temp up or down when we are gone and turn it back up or down right before we come home.

            Great Thermostat!
            I purchased the Sensi Touch Wi-Fi Smart Thermostat for my office condo. It was very easy to install just following the directions in the app. It is easy to use and super convenient to turn the AC on on my way to the office. I arrive at the office and it is already cool. Additionally, the app informed me of a rebate opportunity and submitted it for me. I received notice that I was approved for the rebate and will be receiving a check for $85 from the local utility company. I'm very happy with this purchase!

              Total control
              This was so quick and easy to install. Now I have control over how hot or cold the house is.

                Excellent addition for any residential AC system
                I had my Sensi touch screen thermostat professional installed. Took the tech less than an hour to install and set up. I have it linked to my android phone. It works beautifully and has cut my AC daily run time down to around 3 hours or less. I would definitely purchase it again as well as recommend to others.
