From the couch, the car or the airport lounge, Sensi thermostat provides complete control of your home comfort. Anytime. Anywhere. Using the free Sensi mobile app, you can remotely access, change and schedule your home temperature - with the swipe of a finger. In fact, when you use programmed heating and cooling schedules, you can save up to 30% in HVAC related energy costs. Your Sensi thermostat is designed to install in 15 minutes or less, even if you’ve never installed a thermostat before. You don't even need to know what kind of system you have; we'll figure it out for you right inside our free app. And because it doesn't require a “C-wire” in most applications, your Sensi thermostat works with most heating and cooling systems. Sensi thermostat is built with precision control and comes Energy Aware® certified. With unique cycle rate settings, Sensi will always keep the room temperature within one degree of where you set it - a challenge for many other Wi-Fi thermostats on the market.

  • Connect Sensi thermostat to your home Wi-Fi network and control from anywhere via free mobile application (compatible with android and iOS)
  • Optional 7-day scheduling helps reduce wasteful heating and cooling when no one is home
  • Quick and easy DIY installation in 15 minutes or less; the Sensi mobile app includes a step-by-step installation guide and video tutorial
  • No C wire required for most HVAC applications
  • In-app local weather information and indoor humidity readings
  • 3-year warranty
  • Easily control your Sensi thermostat with Amazon Echo and Wink app (no Wink hub required)
  • Sensi is not compatible with line voltage (2-wire) and proprietary/ communicating systems, and old millivolt (mV) wall, in-floor or gravity furnaces. Refer to the user manual and compatibility information to make sure your router has no known compatibility issues with Sensi.

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. In fact, the best part about this model is that it blends in to the normal decor of your existing home without looking like it's from Star Trek or from the year 2040... 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

He means, can you use batteries to power it, or do you have to use a power wire. Obviously you have to use the existing wires to control the AC, but not everyone has a power wire. I'd like to know the answer for this too.

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!

I first checked to make sure the wifi signal was sufficient in the area of the thermostat. I used an Android app to measure it. Reflectivity and absorption of microwave signals used in wifi can make placement tricky. Line of sight is best. Mine was not but still had a -55dbm signal available so it hooked right up. If you cannot get yours to hook up, try moving your hub even a few inches and try again. We have had a balmy fall and I have been running mine at 60 degrees. This week we finally had some chilly mornings in the 30s and I moved it up to 68 and then back to 60 when I got to the office. Works very well with my Wink hub 2

Rated 5 out of 5 by from Great investment We probably recovered the cost of installing this thermostat when renters checked out of our beach condo last week--and left the a/c set on 60! We were able to adjust the temperature remotely and prevent damage to the unit before the cleaning crew would ever have found it. If there is a sudden drop in temp, we can remotely change it from a/c to heat and prevent plumbing damage. It was easy to install and is one of the few which doesn't require a C-wire.

Very clear instructions, and using an app to ask questions so it presents the relevant installation steps is brilliant. The unit works as advertised and I feel it is very accurate. I haven't programmed multiple days or times because I'm home 24/7 so adjusting temperatures during the day doesn't appeal. I may lower it just a tad at night though, just haven't got around to it. I also set up the Alexa integration and it works perfectly. Then there is the coolness factor of being able to send a voice command to raise or lower the temperature. Or monitor or change it on my phone.

Although this thermostat appears to be "Plain Jane" compared to the modern cool round ones, it has all the necessary features that I wanted and is offered at a great price. Telephone support was very good, they actually answered the phone on the first ring and were able to solve the technical issue in about 20 seconds. I have had it about a month and it meets or exceeds my expectations.
