From the couch, the car or the airport lounge, your Sensi thermostat makes it easy to remotely control and schedule your home comfort - Anytime. Anywhere. Designed to work with the wires you already have, Sensi thermostat does not require a common wire (c-wire) in many cases, so it is compatible with most heating and cooling systems* (U.S. and Canada only). The intuitive app walks you through each step of installation and configuration so you don't even need to know what kind of system you have. Set your Sensi thermostat to automatically adjust your homes temperature for location-based temperature control with geofencing, or quickly create a 7-day schedule to reduce wasteful heating and cooling when no one is home. If you need anything, we’re here to help. Visit sensicomfort.com/support for around-the-clock access to support articles, instructional downloads and comprehensive support videos. Our highly-trained Sensi Support Team can be reached at firstname.lastname@example.org or 1.888.605.7131, seven days a week. *Does not work with electric baseboard heat and some other systems. A c-wire is required for heat-only, cool-only and heat pump systems without aux. Check compatibility using the free compatibility tool on our website to make sure Sensi will work in your home.
My review is mosty "versus the Nest" because I've had three different Nests and know that one well, and I like this one better.When my Nest died last month, I decided I was going to buy a thermostat from a company with a history of making thermostats work reliably.I would have installed this myself, but my A/C guy who installed my system and troubleshot my Nest two years ago ... and then came back and troubleshot the replacement Nest last month said he would remove his loaner 'stat and install whatever I decided to buy.The one feature of the Nest I knew was hooked on was the ability to change the temp from my phone. Sensi and several others do that now, so I had a few to choose from. In my research I learned that my primary complaint the Nest - that the temperature swing was too wide - was addressed by Sensi's "cycle rate" setting.I like that the Sensi wall unit operates like a traditional thermostat. Nest's no-button design is cool, but using a thermostat is not a lecture in UX minimalism, and black-and-chrome doesn't really disappear into the background of my home (white trim and all).The Sensi is actually an easier DIY install than Nest (screw-down terminals vs. push in notwithstanding), and the main thing I would tell other folks is: install the app on your phone first and let it walk you through the installation.This, Sensi, is what I want in a thermostat. Convenient, reliable, programmable, understandable. I am okay with a modest premium for being Internet enabled. It's half the price of Nest and doesn't intimidate non-technical users. You can keep your auto-programming feature - I always fought with the schedule it created and with two young children we're home most of the time anyway. You can keep your monthly energy usage report - it didn't include enough detail to be useful anyway. And you can keep the space-odyssey design - it might be alright in the stainless-and-black kitchen, or media room, but it doesn't work upstairs.Granted, we didn't also install a second Nest to have more temperature sensors, and we didn't buy their $200 talking smoke detectors which also report environmental statistics back to the thermostat. But I've got what I need from my thermostat now.P.S. It took the last Nest two years to go kaput, but I'll update here if that happens to my Sensi.Update: After about a month I'm still very happy with Sensi. Most people won't care about this but being a network security engineer, I'm impressed that the thermostat has exactly 0 open TCP ports, outbound communication is with one IP, and total traffic is very modest. Nest communicated with a whole bunch of different IPs and was much more "noisy" on the network. Good work, Sensi dev team.
--UPDATE: 3/22/2017:I just noticed that Keypad Lockout is now an option on the app, so if you have kids or roommates that you need to prevent from messing with the air, you will be happy about this option! (Original review below).--UPDATE: 3/4/2016:Now works with Amazon Echo! So you can control your thermostat with your voice by speaking to your Echo device! Very glad to see this addition. However, still lacking more features for the app (see original review below).--I had been wanting to get a WiFi Thermostat for a long time now, but I held off because I was worried that I would buy one that wouldn't be compatible with my home or that I wouldn't be able to figure out how to install it. I finally gave in and purchased this Sensi thermostat, and I am extremely happy with the purchase.Set up could not have been easier. The app walks you through the installation. You select the wires that your current thermostat has, and then the app tells you what to label them and where they will go in the new thermostat. I had never replaced a thermostat before, and it took me under 30 minutes (which includes unboxing, looking for screwdriver, looking for AC unit shut off switch, watching how-to videos included with the app, etc).The actual operation is simple and efficient. Within minutes, I was able to set up a generic schedule based on when we are usually home. I love being able to change the home's temperature from my bed, office, or anywhere in the world with an Internet connect. The first few days I played with it a lot, but now that I have tweaked the preset schedule, I don't even have to worry about it anymore. If I am out or home at unusual times, you just adjust the temperature manually, and it will temporarily suspend the preset schedule.The thermostat looks nice, aesthetically, on the wall, and since I apparently had this magical "common wire" I have the option to keep the LED light on at all times, which acts as a night light in the dark, and makes it look even better.The app is handy because it also tells you your local Hi and Low temps from the forecast as well as the humidity in your home, upcoming schedule, set temp, actual temp, and the background is either blue, red, or grey depending on if your system is on Cool, Heat, or off at the moment. There are also more advanced options that I do not yet understand.The only thing this is missing is a few more advanced options for the app, such as specific alerts (like if the temperature is changed manually, I would like to be able to get an instant alert on my phone) and an air filter change reminder that can be set for a certain amount of time (like 1, 2, or 3 months). I think it does alert you if your house reaches an extreme temperature, but I have not had that happen yet. Also, I have not been able to figure out how to switch between "Cool" and "Heat" modes within a schedule (without using the "Auto" setting).I also purchased and installed the wall plate: Emerson F61-2663 Wallplate for Sensi Wi-Fi Thermostat, White, White (was approximately an extra $10). I think it should have been included, but I imagine not everyone wants one. It isn't much bigger than the thermostat, but I think it makes it look nice. I included some photos so you can see for yourself.Feel free to ask me any questions in the comments and I will do my best to answer them.
