Emerson - Sensi Touch Smart Programmable Wi-Fi Thermostat-Works with Alexa, C-Wire Required - Black

Works just as well as my upstairs controller that cost 5 times as much. No issues whatsoever. It was easy to install and works like it should.

This thermostat was easy to install and even easier to set up and program. I love the fact that it is compatible with Alexa and you can set up routines. Great value for the features.

Excellent choice. Awesome connectivity and qualifies for rebates, too.

As an HVAC contractor and service tech, I have installed a lot of thermostats over the years, and I think the Sensi is a solid choice. Read on for more info on setup, use and comparison to some other similar thermostats I have dealt with. First of all, Emerson Electric, who makes the Sensi thermostat, also makes a wide variety of electrical and HVAC products. From Copeland compressors, that’s probably in your HVAC’s A/C or heat pump, to Insinkerator disposals, to electric motors, and more. It’s a quality product from an industry leader. You will need the C (Common) wire to power the thermostat as there’s no battery option with it. Most modern HVAC installations will already have this wire ran, and in use if there’s already a digital thermostat installed. Especially if it's a heat pump. The Sensi is compatible with pretty much any system that uses a 24 volt AC control circuit. It’s not compatible with systems that run line level, 120-240 volts, through the thermostat. WiFi is 2.4 Ghz band only. Download the app via QR code or search for it on Android or iOS. Run it and it will tell you how to remove your old thermostat and install the new one. With plenty of info that includes photos and drawings, they make it easy enough that I think pretty much anyone can do it. Most of the time, residential and most commercial thermostats use the same labels and wire colors. Red to R, Yellow to Y, Green to G, ect. But this isn’t guaranteed. That’s why they include labels and explain what to do with them. If you need them. Taking photos of how your old stat is wired up is recommended by me as well as the app. I know this is a no-brainer, but I highly recommend that you turn the power off to your HVAC system before changing the thermostat. Not because the 24 volts AC the control circuit uses will kill you. It won’t unless you go to the trouble of inserting electrodes into your skin or something way beyond just touching the bare wires. Dry skin resistance is too high. Even wet skin would only give you a tickle. What you might do is blow the 3 or 5 amp blade fuse (See photos) that protects the 24 VAC control circuit components. You pop that fuse and you’re going to have to replace it or your HVAC isn’t going to work. Unless you know what you’re doing you will need to call an HVAC pro to come replace it. I have been on many service calls replacing a blade fuse that a DIYer popped changing a stat. That can mean getting into an attic, crawlspace at worst or simply a garage or basement if you’re lucky. Outside if it’s a package unit. The 4.3 inch color LCD touch screen display has a resolution 480 X 272. The menus of options and modes of operation are well laid out, easy to read and understand. (see photos) It shows the inside temperature, set point and humidity. You can also adjust the offset for both with the app. The app shows current outside temp and forecast low and high temps. Sourced from the internet for your locality. Using the app to set a schedule is a bit easier than doing it on the thermostat itself. The Sensi’s screen is Blue in Cool and Red in Heat modes respectively. I understand where they are going with the Red and Blue thing but I hope they update it to give users a choice. They can stick with the factory theme or choose the color the thermostat’s display is. Uploading wallpaper would be even better! The nightlight puts a glow around the thermostat is pretty nice. I wish it had a brightness setting. (see photo) The thermostat kept my house at a consistent temperature and humidity as expected. Build quality is plastic but feels sturdy. Sensi plays well with Alexa and Samsung’s SmartThings. I don’t have or use Google Nest Hub, so I didn't test it. Geofencing is a nice option. Especially if you don’t run it on a set schedule. You can set reminders for changing filters, clean out condensate drain, (I highly recommend) and to check or change a UV light, if you have one installed. You can input your HVAC contractor info too. Compared to other similar stats I have installed: A similar Honeywell color screen stat has more options for colors and shows more info such as local outdoor temperature and local forecast via WiFi. Not as easy to set up the app. Install is about the same. Touch screen is not as sensitive and you have to hit Done after making any changes. I used one for 6 years until I got the Sensi. Nest and ecobee thermostats are good, but can be expensive. They are also smaller. I would choose the Sensi over a them for straight forward ease of use. Conclusion: As an HVAC contractor, I highly recommend the Emerson Sensi thermostat. Even better if it’s on sale!

The Emerson Sensi Touch Thermostat is a very welcomed addition to my home. This product has served as a suitable replacement for my existing thermostat panel. Setting up the product was extremely easy. Emerson should win an award for the intuitive, step-by-step guide found within the app for installation. Any nervousness I felt prior to tampering with the wiring immediately dissipated with the detailed explanations at each step of the setup process. Once installed, I did have to tweak a configuration because the heat and cold settings were performing in the opposite manner of the desired action. Fortunately, this was explained in advance by the app. As far as performance, I've been mostly satisfied. The app interface and touch screen is very responsive to the changes that I make. My selected inputs were immediately executed without any buffering or hiccups from the system. Integration with Google Assistant was seamless, and my commands were completed as requested. I have two minor complaints from my usage of the thermostat. I have encountered an issue where the humidity level of my upstairs has gotten unusually high temperatures. Fortunately, I receive notifications for this, but this was never an issue with my older thermostat. However, my older panel wasn't a smart thermostat so this thermostat could be picking up a possible issue. My other gripe is that the thermostat doesn't necessarily provide tips or specific settings that could lower AC bills. As a consumer, I appreciate the ability to set schedules and make AC changes on the fly. I just believe that more suggestions on best practices could improve overall experience. I'm very happy with the Sensi Touch Smart WiFi Thermostat. It's just as easy to use as it is to install. This is a quality product capable of competing with other high end brands.

So, I had another name brand Wi-Fi thermostat but thought I would try this out. So far, I'm very impressed with this thermostat. Set up will be easy for anyone who has a typical home unit with a common wire (you must have this common wire) I went a step further and added my AC humidifier to the thermostat. This is a very nice bonus for me, as in the past I would have to go downstairs to adjust the manual thermostat on the side of the furnace when temperature changed outside. Now I can set the desired humidity level and forget about it. Back to set up, you will download the Sensi app and follow the instructions. It will walk you through your wire connections, Wi-Fi setup etc. If you need more advanced setup (adding what was not already connected) like myself, I suggest you go online and download the PRO installation guide, as this will identify what each connection is for. The Sensi app does not show this. It simply asks you to select each wire you currently have, then tells you what connection to plug into on the new thermostat. Of course, if you are not comfortable with wiring then you may want to simply hire a professional to install this for you. Speaking of the connections, the wire simply pushes into a clamp like grip. If you need to remove the wire, you simply push the lever underneath the wire and pull the wire right out. Very nice feature. Follow the directions carefully, and don't forget to turn off the power supply to your AC and furnace before starting. Since I had a unique set up, I had to call their customer service department for assistance. They were helpful in walking me through my set up. I was on hold for about 20 minutes the first time I called, then when they finally answered, my Bluetooth failed and the tech could hear me. That was very frustrating, but what I found impressive, is they figured out I had a phone issue and they called me back. That is great customer service. Note - I did have to run another wire since I needed 1 more for my humidifier unit. You can set up and control multiple units with this thermostat, another nice feature. Compatibility: Conventional 2H/2C Heat only and Cool only Heat Pump 4H/2C Geothermal, gas, oil, electric and dual fuel The programming options are fantastic. You can set schedules for COOL, HEAT or AUTO. The Auto feature will allow the thermostat to turn on your heat or A/C depending on the needs. I see this as a great feature for someone with a second home, or if you are away for extended periods of time. Of course, it is Wi-Fi so you could change the settings remotely if you have Wi-Fi connected in the home the thermostat resides. Schedule types: -Programmed Schedules - provide you endless options that allow you to set the home temperature based on your own needs. -Geofencing- This will set your thermostat back 3 degrees when you leave a 3 mile radius from your home. -No Schedule Fan Mode- here you can turn the fan on manually or leave in auto mode. You can also tell it to circulate your air anywhere from 10% to 100% of the time. The app will also show you your usage per day for Cool, Heat and Fan. This Sensi Touch Smart Thermostat is compatible with Amazon Alexa, Google Assistant, Apple HomeKit and SmartThings. I use Alexa. It was easy to add to my Alexa app and it's a pretty cool feature. Once installed on your smart phone, you can control your Sensi thermostat with your voice. Visually this is a good-looking unit as well. The background color on the display changes dependent on the function it is providing. So, if A/C in ON it will display a light blue background if it's heating it'll display and orange color and when it's OFF it'll display a gray background. I appreciate the Large digital readout of the current temperature, nice for old guys like me. You also can view time, temp setting and humidity percentage. Another unique feature is a light on the back of the thermostat called Back Glow. You can set this to ON or OFF. When ON it will give you kind of a night light effect. I do wish you could set this on a schedule, for instance have go ON at night and OFF during the day. Temperature accuracy is very good. See pics for temp reading comparison. Overall, I am very impressed with Sensi Touch Smart Thermostat and the App, I would highly recommend.

Now an excellent modern-looking thermostat with a nightlight for guests to quickly locate at night. When one is not home, I can control it remotely via the Sensi app on my phone (Android). Designed very well and has an excellent interface with many cool features. In my case, the installation was fast and easy, thanks to the app installation guide wizard. Before removing the old thermostat connected to the wires, the guide recommends taking a picture as a reference. On the app, you tell it what wires are on the old thermostat, and then the app will give you a custom mad connection depending on your current wires. The kit comes with stickers to label your specific connected wires. After all the wires are attached to the new base plate, the next step is to set up the Wi-Fi configuration. Once all that is complete, use the Alexa app to add this device to your account to be able to control the thermostat with a voice command. My favorite settings in the app that would help me save energy costs are (1) Service Reminder for filter and maintenance, (2) Min & Max cooling/heating temperature, and (3) Humidity Control. I rarely lower my cooling temperature below 73°, and once I had a guest staying overnight, someone dropped the temperate to 67°. With the Senci app, I don't have to worry about someone playing with my thermostat. The Service Reminder setting does notify you of the important task of changing the filter and doing system maintenance. For an A/C, flushing drain pipes and coil cleaning prolong the unit's life and save on cooling/heating costs. Overall, I am satisfied with the Senci smart thermostat. Easy to install, the ability for remote control, easy to program, service reminder, min/max control setting, humidity control, modern look.

The Emerson Sensi Touch Smart thermostat is an impressive smart home product from a company that is well known for their conventional HVAC controls. I was a fairly early adopter for smart home gear, with almost everything in my home being controlled through SmartThings, with one smart thermostat downstairs from one of the earliest smart thermostat brands, and previously a Z-wave thermostat from a different 'traditional' HVAC brand in my bonus room (on the same central AC unit, with a dual zone control board to allow for separate controls). With the Sensi, I replaced that Z-wave thermostat upstairs and it was an incredibly easy swap. The Sensi includes a 'base' that you attach to the wall and has nicely labeled terminals for all of the thermostat wires. Included in the package, there are some wire labels to attach to the wires as you remove them from your existing thermostat, as well. The Sensi app also guides you through each step of the process. (side note: it's really nice that we're finally getting to the point that brands asking you to download their app to set something up have actually made it worth doing so vs a regular manual or PC web browser setup). I was up and running in less than 10 minutes, including the trips outside to flip the breaker on my HVAC unit. The Sensi app is well made, and Emerson makes a point of telling you that they don't sell your data for advertising purposes - which is comforting (sorry, HVAC pun). Of course, I then integrated the Sensi thermostat into my SmartThings setup and Google Home, so those privacy protections from Emerson themselves are kind of moot :). The integrations work perfectly and are pretty much 'one touch' in either app. If you don't have a full smart home, the Sensi app works well in a standalone fashion, too. It provides warnings if your AC unit doesn't seem to be keeping up with the temp in your home, and lets you control the temperature from afar. This is not a 'learning' thermostat - it just connects to wifi, so you must still set your own schedules. As far as I can tell, it doesn't offer geofencing either. I have never had that work reliably for the other brands I've used, so no big loss. However, one thing I love about the google home integration is being able to tell my Google assistant to change the temperature while I'm on the way home - on days when I'm not sticking to the pre-programmed schedule, this is really nice. Definitely consider the Emerson Sensi Touch if you are in the market for an attractively designed, connected thermostat without a lot of fluff. This thing just does its job well, at a really good price.
