Product Overview

The Emerson Sensi Wi-Fi Thermostat is a truly universal Wi-Fi solution that provides remote access to your home comfort. Anytime, anywhere. The free Sensi app lets you stay connected to your thermostat via smartphone, tablet or PC. Easily set and control your heating and cooling schedule with seven independent day in-app programming options. Sensi Wi-Fi Thermostat users can save up to 30% in energy costs by adjusting their thermostat schedules around their lives. Because Sensi is built by Emerson, precision control is at your fingertips.

Answer: 
It's supposed to maintain the schedule that's active if the wi-fi connection is lost, and believe me, the wi-fi connection on mine drops out a lot. But my schedule still functions without the wi-fi. The schedule can't be revised without the wi-fi connection. The wi-fi connection on mine drops out every few monts and I have to delete the thermostat in the app and reinstall it. A real pain.

Answer: 
I have to disagree, as my new thermostat has lost its internet connection literally as we speak. It is set to 70 degrees but the actual temperature inside my house is 62 degrees, and the furnace will not turn on. It's even set to "on" instead of "auto". Nothing's wrong with my furnace...just this thermostat. Brr!

It does not rely on the internet for it to function.

It functions normally as if you did not even have a wifi-capable thermostat. The only part about not having an internet connection is that you will lose the capability of controlling it wirelessly. So if the internet goes out for a few days you will not lose any functionality. Hope that answers your question? Read Less

Answer: 
Hello,
The Sensi is not a wireless thermostat. It does require wires between the thermostat and your system in order to operate your system properly. Please email Sensi Technical Support at support@sensicomfort.com if you have questions about your specific system compatibility. Thanks, and have a great day!

Yes, I run the app on both my smartphone and my tablet. Access to your thermostat is essentially thru the cloud via the manufacturer's website. Both devices simply need to login into the app which in turn is logging into your account/thermostat on their website.

Rated 4.6 out of 5 by 190 reviewers.
Rated 5.0 out of 5.0 by Easy Install and Set-up. Nice Wifi Thermostat w/ No C Wire Required The Sensi Wi-Fi Thermostat perfromed as advertised. The install and set-up was easy untalizing the Sensi app. As a novice, I was pleased at how easy this item was to install. It took me about 30 minutes from start to finish. After using the thermostat for a few months, I am pleased with the overall performance. The thermostat is easily programable from your cell phone and the ability to change the temp from anywhere has been useful. When selecting this thermostat is was important that it did not require a C wire. Many of the other wi-fi thermosats on the market require a C wire that is not availalbe in older homes. I am very happy with this purchase and plan to purchase another one for my 2nd system. Although the installation app was helpful, it would have been nice to have a manual included. That is the only drawback I have seen with this product. May 9, 2016
Rated 5.0 out of 5.0 by Love this Thermostat, Pleasantly Surprised After some initial concerns about privacy / security that I had about the thermostat on the home WiFi - which were fully addressed by the Home Depot / Sensi team - I got the thermostat installed in under 30 minutes...a personal record for thermostat installation for me. ;) The installation is made so simple with the Sensi app walking you through the process step by step, telling you exactly what to do and including helpful things like wire labels for when you are disconnecting your old thermostat / getting ready to install the Sensi. Now that it's fully installed, I love it - love the programmable aspect, of course, but really love the ability to control via the app on my phone. Excited about the energy efficiency this will make easy for me - and glad to have a bit of smart technology in my home. April 30, 2016
Rated 5.0 out of 5.0 by Great! Easy to install. I did have to run a new wire for the common, since my original only had 2 wires. Really like being able to wake up and turn up the heat from my phone before I get going. Also peace of mind when traveling to check the heat settings. May 7, 2016
Rated 5.0 out of 5.0 by Excellent Thermostat This is a great thermostat. I removed our old "programmable" thermostat and replaced it with this. the old unit had DST dates hard coded in the ROM and they were no longer correct since the dates shifted, that became a real pain. My house has 3 systems, the one I installed this on is a heat pump with electric backup. Wiring was very easy using the app on my Android tablet. WiFi setup was easy too, and has worked since day one. To control this device, sometimes I use the Android app, and other times I just visit the webpage with my laptop. The online control is very well done, kudos to the programmer(s). Background is blue when cooling, red when heating, and gray when system is not running. There is a help center but I have never needed it, the software is so intuitive. Very simple and works great! I have included some screenshots of the web app from my laptop. I took some extra time before reviewing this because I wanted to live with it for a while, glad I did. I will be buying more! Buy this, you will not be disappointed! April 9, 2016
Rated 5.0 out of 5.0 by Easy to Install -- Easy to Use Surprising easy to install -- the directions were so easy to follow and we were done in about 20 minutes. We installed 2 -- one for up and one for down with connection to an iphone. Suggest you purchase the Wall Plate as well as there is never a perfect fit and the plate completes the look. I did have to call the service center to be sure I had the iphone connection right for the second thermostat and that was also amazing. Little wait time and smart person to help on the phone. I do not normally submit reviews, but this was so great, I had comment. February 23, 2016
Rated 5.0 out of 5.0 by Best investment we ever made. Our old Thermostat didn't work quite right so we searched and searched for a good value Thermostat that we could add to our SMART HOME stuff. This one is that one and it works just great. It keeps the temperature a constant for the temp we have it set at. I can create different schedules and it does the rest. Last week we left for a 5 day trip and we got 2 hours away and I remembered that I forgot to change the thermostat. I pulled out my phone and clicked on the app and changed the scheduling to the Vacation schedule I had created. I spent the time away not worrying that the AC was set too low. I haven't set it up with the ECHO yet so I don't know how it works with that yet but I will soon. July 7, 2016
Rated 1.0 out of 5.0 by Nice Thermostat...BUT, has wifi issues This thermostat works well, and is easy to install. But, it constantly drops the wifi connection. Customer service is responsive, and has lots of suggestions including unmounting the device, removing the batteries for a reset, or even suggest replacing my router. With no wifi, programming options cannot be accessed. Can't be programmed from front panel. There is also no front panel procedure to reset the device. Replace my Asus router? I have approx 15 devices connected to my Asus router, including security cameras, and they are all fine. I didn't buy this in order to hire a computer tech to come in and change my wifi system. So, back it goes (I hope) and re-install my 15+ year old non-wifi programmable White-Rogers (same company as Sensi?) thermostat, which continues to work just fine. July 17, 2016
Rated 5.0 out of 5.0 by super easy install and smart phone app is intuitive The one cool thing that seems to be missing from the other reviews is that the app asks you what wires you have and provides instructions specific to your situation. So easy and working perfectly! The unit uses batteries in place of the c-wire requirement. For the simplicity of install and not having to pay a premium for contractor to install, I can deal with changing 2 double A's every 2 years. No issues with wifi for me. Just follow the simple instructions to connect. Oh btw, $70-100 less expensive than others with similar features. Only thing I'm missing is the fancy touch screen, but I have that on the Sensi iPhone app. June 2, 2016
