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.

Affordable and Easy to Set Up and Use

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!

Liked it so much I got a second one

I purchase this and install it. I have a Air Conditioner with Heat pump because live in TN that don't behave basement. It seem when I had cool on heat would kick in. Call support and the person was very helpful.  He ask me to send photo on way old thermostat was hookup and way I had New one hookup. He had me move to wires and help me reprogram unit and now works great. The wireless on it is great so can change it by my smartphone. Picture of New and Old hookup

Recently, a friend had recommended I install a wifi thermostat in my home. I purchased this one through my energy providers online store. As I was in the market for a new one, this thermostat was a no-brainer for me. Couldn't be happier with my choice. As for installation, I am a DIY kinda guy and had no trouble at all with this install. Before receiving the tstat, I had installed the app on my phone and went through a mock setup. Once you're ready to put the tstat on the wall, the app will guide you through the entire installation. For me it was like.....15 minutes tops and it's on the wall, paired with wifi, and I'm running with the app. I wanted a base plate on the wall. They were out of stock on the plate for this model, so I took a chance and purchased the one for the touch model. It worked fine. I just had to lightly file two small beads on the plate to allow the tstat a flush mount against the plate. I like the look. It's optional, you don't have to have it. As for functionality, I love it!!! The wifi and the app make all the difference. I've had programmable tstats. To me, they are clumsy at best. With this setup, from ANYWHERE, I can see my current system status, add or alter current or upcoming system schedule, check daily usage, and all kinds of other good stuff. What I now have here is a boy toy, some would say, but if used properly will save you energy, wear and tear on your hvac equipment, MONEY, and provide you a greater level of comfort and confidence in your home. Last week, my wife and I joined friends out for dinner. Before leaving I noted the tstat was at 71 degrees, as it was set to be. We were going to be gone for several hours. Using the app, cause it's more fun then using the tstat, I set the heating temp to be 67 degrees. I asked our cat if he was ok with that and he was fine. For him, it was better than being outside, which was 20 something degrees. As it turns out, and I know this by monitoring the app, our indoor temperature never got below 69 degrees while we were gone, and our heating system did not have to kick on. Then, at the right time, before heading home, I took the schedule out of hold, calling then for the preset 71 degrees. I watched the app respond, the phone screen turns orangish when heating, and knew our home would be toasty warm when we got home. Which it was thank you very much. We were away from home for nearly 4 hours. I had eliminated 2 maybe 3 heating cycles. You do the math. Yes, you have choices. There are a lot of wifi thermostats on market today. I made a good choice. To say it again, Thank you Ameren, my energy provider, and Emerson Sensi, for a great product and app.

Couldn't be happier! Great app and thermostat.

this was insanely easy to install. I was waiting for my husband to get home from work %26 I decided to mess w it a little before then %26 I was pleasantly surprised to learn that it was only a few wires %26 less than 10 minutes of fiddling around to get it installed. setting up the app took longer than the install! easy to setup, easy to run, easy to maintain. I'm happy with it

I recently purchased three Sensi thermostats. They came with complete installation directions and I installed them
Myself. It was easy. I love the app where I can set the temperature for each floor of the house. I recommend Sensi to anyone.

My new Sensei was installed through our local utility service. As a senior, I was reluctant at first due to the connection to Wi-Fi and app, but after I learn to set up schedules and control the temperature through my eye through my cell phone it was a breeze. The Sensi thermometer also changed the performance of my furnace, making it more quick to react when you reset the temperature best thermostat I've had in 20 years. It looks more modern than the others also.

A ver decent upgrade

Overall happy with the thermostat only issue is using so many batteries says c wire not required but after 1st winters use looking into c wire

Installation was super easy using the app tutorial. The thermostat works great and the app's UI is really user friendly. There's a lot of customization that's possible. My only criticism is that there is no Hold feature you can toggle in order to determine wherher a manual adjustment is held indefinitely or not. When you manually adjust the temperature, it sets an automatic hold and it stays at that temperature and won't automatically resume the program at the next scheduled time interval. You have to manually select your program again if you want it to resume. Not a big deal but I would have liked to have that feature.

I was excited to get this but then........  It was nearly impossible to get to connect to Wi-Fi.  I called the help center (which was very helpful) and finally got it to work.  Within about 4 or 5 hours it was offline.  I've tried numerous times to get it back online with no luck.  My router is only about 35 feet away from the thermostat, so I doubt that's the issue.  So now I essentially have a regular hand operated thermostat.

Will not stay on line
