Great Value and Easy to Install
This Smart Thermostat makes an excellent choice for the typical user who wants straight-forward, intuitive controls with the added advantage of a WiFi connection. The installation was extremely easy using the step-by-step instructions in the Sensi App. I was surprised at the clarity of the instructions and the ease at which I was able to install it. And once installed and connected, it works just as advertised and the App provides easy to understand and easy to change controls. I would highly recommend this Smart Thermostat! Oh, and the value is excellent… what I received versus what I paid.

Step by step app is AWESOME!!!!! Install app BEFORE removing old thermostat.
We’ve had this thermostat a month and I really like it so far. It makes me think our old thermostat wasn’t actually working for a long time before it started setting itself to 85°. Since it wasn’t even programmable, I knew it had to go and if I was going to upgrade I may as well go with something just a bit more…modern than a set-temp-and-it-stays-unless-you-change-it thermostat. I’m going to do pros and cons below. I do want to say, I took my old thermostat off the wall first, wrote down all the wire colors and the letter each was connected to on a piece of paper. The app removes the need for pen and paper. I just used my pen and paper to place the flags mentioned below on the correct wires.Pros:1. This thing is super easy to install. Open the box and there are instructions for you to download the Sensi app. Once the app is downloaded it has you choose which letter slots you have wires connected to (R, RH, C, E, OB, etc.). The app then tells you how to use the flags they provide to label the wires. For example I had a wire that went into a slot labeled “R”, but Sensi only had “RH” and “RC” (I think it was RC), so the app told me which R my wire needed to go in. Not having any electrical wiring experience, the app was SUPER helpful. It even had you take a picture of your wiring to save to your phone, just in case.2. The piece that attaches to the wall has a built in level. I am super annoyed when things aren’t straight on walls, so this right here, was awesome.3. The app is really easy to set up. I just have a daytime and nighttime cycle, but I could set up all kinds of things super easily. Vacation modes, turning the AC up when I leave the house… It was great. It even walked me through how to sync the app with my Google assistant and the Samsung Smart Things app, which I didn’t end up continuing to use. (See cons #1)4. The report that tells you how long your AC is running is really helpful as well, especially since we had issues last year with it not being able to keep up. We have better insulation and updated windows and it’s nice to see they are working, even when it’s 99° with a heat index at 112°. (See cons #2)5. I like that you can do things like temp and humidity offsets, have the AC turn on to help maintain proper humidity levels (we live in Florida, so this is a big thing for me), change the cycle rate (ended up choosing this one over another brand because people had issues with not being able to adjust the cycle rate on that one), and easily turn heat boost on or off. (See cons #3)Cons:1. It doesn’t work with Bixby. This is something I don’t really understand, but I’m guessing they assume if you’re gonna use Bixby you use Smart Things? But I can just use Google for that instead.2. The recent usage section only shows how long the AC ran that day, not which times it ran or how long at a time it ran. It would be nice to see how long the AC was running at a time, especially in the afternoon when it gets really hot. I have not yet gotten a monthly report since I got the thermostat mid-June and it’s now mid-July. Interested to see what the monthly report looks like at the end of the month.3. Sometimes I had to change settings a couple times before they “stuck”. I found after changing a setting I needed to wait a few seconds before returning to the settings menu and that helped.4. Shortly after I got the thermostat the AC drain line clogged. This resulted in my app/thermostat constantly saying cooling was on, but the AC wasn’t running. My usage for that day was like 21hrs, but I know it wasn’t actually on for the majority of that. Not really a huge issue, but you won’t have an accurate reading for that day.Summary:Overall, this is a really amazing unit and I have been really glad to have it. It was seriously a breeze to instakl and set up and functions well. I do wish I could connect it to Bixby without using Smart Things and I do wish I had a more detailed daily usage report, but those are very small inconveniences. I normally keep our house at 78° during the day and 77° at night and sometimes that feels cold. I would often feel hot before and wondered if our AC was not working correctly, but it would seem it was actually the thermostat. Very happy with this purchase.

Smart, efficient, and super easy to use!
This WiFi thermostat has made controlling the temperature in my home so much easier. The app works perfectly — I can adjust the heat or AC from anywhere, even when I’m not home.Setup was quick, and the interface is very intuitive. I also like that it learns my schedule and helps save energy automatically. Definitely a great upgrade if you want more comfort and efficiency at home.

Wireless operation with battery backup
Installation instructions were very clear and easy to understand. The installation went very quickly. The unit was easy to program and has been working flawlessly since installation. The reason I bought this model because it was wireless, did not require running a new cable and has a battery backup. I am very happy with the product.

It just works
Why did you pick this product vs others?:I came from a Nest Thermostat, two generations, that seemed to never be able to control my central AC system properly. I thought I was making a good decision last year switching to the Ecobee Premium Thermostat after reading all of the mostly positive reviews. It was one of the worst electronic purchases I’ve made, and I love technology. The one I received never seemed to measure the correct temperature or humidity, and that was with putting plumbers putting in the opening behind the plate. I had to offset both the temp and humidty of it by almost 10 degrees, which is simply unacceptable. That one was replaced, and the second was equally as bad. If you pay $250 for a device that’s primary function is to read temperature and humidity accurately, it seems like basic functionality. So, I recently had to start offsetting the temp and humidity on it, and I noticed that it was never reaching the appropriate temperate on the unit all while continually running. As soon as I would turn it off, the temperature on the thermostat would drop two degrees. So, I sought out something different.Enter the Sensi Smart Thermostat. I liked what seemed like a relatively simple device all while having connected integration to Google Home. It was very easy to connect. The WiFi setup was a bit odd as it seemed like it connected, bu the app wasn’t really reflecting that. After getting everything fully installed, I was able to get it all connected and registered. I have a hygrometer hanging on the wall beside the thermostat, and I also have an Air Things Air Quality monitor below it that reads both temp and humidity. Guess what – the Sensi has virtually identical readings for temp and humidity to both of them. It just simply works. Configuration and settings were easy. The app is simple and easy to use. I couldn’t be happier. Don’t waste your money on an Ecobee Premium thermostat, that’s for sure. This one right here does the job and does it appropriately and without complication.

Love it!
I have avoided buying one of these since so many electronic devices are either kludgey or overly complicated. Also installation of thermostats can be a pain in certain circumstances often due to poor instructions. The instructions were great and it was easy to install. It has worked really well and has stayed attached to our internet service even though the ISP often drops out at times. When the ISP gets back on line the thermostat reattaches very quickly. This is a very simple and easy to use device that works well.
