The Emerson Sensi is a solid purchase as far as smart thermostats go, but it isn't exceptional. If there were a school for thermostats, it wouldn't make the honor roll, but it would pass. It has WiFi connectability, so you can program it with a smartphone app. It can be programmed for a full-week's schedule in advance, which it will follow until you change it. Its monochrome LCD display is readable, but won't win any awards for stylishness.
To put it in context, modern thermostats come in roughly three different intelligence levels:
Genius IQ: These thermostats watch what you do, remember what temperature you set them at and when you did it, follow you around with the GPS on your smartphone and devise their own energy-efficient, perfect temperature schemes. These are the thermostats that will run the world one day. They may even be running it now.
Average intelligence: These thermostats are like students who turn in their papers on time but don't answer any of the extra-credit questions. They let you program them using a touchscreen or smartphone app and follow your program to the word -- even if you come home late and don't really need the heat on at 5 p.m.
Dumb as a log: These are the thermostats our parents used. These are the thermostats some of us still use. They let you set them for one temperature and more or less keep the house at that temperature all the time.
No offense to the Emerson Sensi, but it falls right in the middle, average in every way except for the voice control feature, which might count as an extra-credit question on a quiz. If this is what you want, go for it. But if you want a thermostat that's smarter than you are and will know how you want it set even before you tell it, go with something more like the Nest Learning Thermostat or the Ecobee3 2nd Generation.
Super easy to install and use! I can't believe how far home heating and cooling has come. The sensi app gives you the ability to control your home environment remotely...
All the good reviews are right; this thermostat works great, has a very clean interface on both the web ui and the ios app so I won't bother restating all that.
Impressive! Extremely intuitive installation, feels like an apple product. app works well. This feels like a quality product that has been thought through.
This is a great product and we are very happy as the install and the instructions were very easy for us to understand and install...
This thermostat is simple and amazing... This one without a doubt is better than any other thermostat. And it saves you money on your bills.

This emerson sensi was easy to install. You download the software on your iphone/ipad or android free on your mobile app...
Have been using this thermostat for a little over a month and I’m loving it! Can’t beat having the ability to adjust your home’s temperature from anywhere!
The sensi is a smart choice if you want the convenience of a wifi enabled thermostat from a renowned company and won’t miss features like geofencing or usage reports.
I think this is an excellent thermostat... It also has quite a few features, so not sure why others have said it does not...
