Bought this on Prime Day, was anxious to get it and hook it up. The video looked pretty simple so I was encouraged that I could set it up by myself. I did. It was pretty simple once I made a few realizations - nothing to do with the thermostat itself though.The app will walk you through the installation, every single step...except for making sure you completely unscrew the wire fasteners! (Personal realization, easily corrected!) Be sure to have a very small flathead for this. I happened to have one for eyeglasses and it worked well!Once installed, the rest of the process was fairly simple. You can control most functions of the thermostat by the panel itself, the Sensi app, or your Alexa devices.Only con is you can’t not turn it on or off using Alexa, however you can accomplish this using the Sensi app.Overall, I’m pretty happy with this thermostat and it’s functions. Will update if that changes.
I can only review this based on the heat only function as I do not have central air. I have had this product for about 3 months now.I got this on a deal on for about $60 to replace an older Robertshaw thermostat and so far it has been well worth the price. As long as you only expect basic functions and not miracles then this thermostat will be fine.It came packaged very nicely and the setup instructions were very clear. I had it set up in probably 30-45 minutes since I also had to add in a c-wire. It connected seamlessly to the Sensi app and to Alexa once I added the skill.It does have a few short comings. I wish it had the ability to set the schedule from the unit itself. You can only set it through the Sensi app. The app itself is not very polished, it’s kind of low grade and very basic but still functions well. On the thermostat itself you can only have either the humidity level showing or the time showing but not both at the same time. Don’t know why that bothers me but I wish I could just have both showing. Also, the system emails me when the humidity level reaches 70% in the house and I have not found a way to change this setting other than disabling notifications all together. My thermostat is right outside of my master bathroom so when we shower in the master bathroom it detects higher humidity levels. I just deal with the emails telling me the humidity level is high since I don’t want to disable all notifications. Hopefully they update this.The temperature and humidity levels seem to be accurate as I have other thermometers in my house and they are very close to the same reading. I have not used the scheduling feature for long periods of time since it is summer and I only use it for heat. The little I tested it, it worked fine and as expected.The Alexa integration honestly is kind of low grade. It works well as far as voice and asking what the temperature is, turning the heat up or down, and basic stuff like that. But if I want to turn my heat on from the Alexa app I have to do it by voice since there is no on or off button (see photo) or go to the Sensi app. Once it is on you can turn the heat up and down (see photo) and create Alexa routines but you still need to use the Sensi app for setting schedules and such. It is also a bit laggy. If I tell her to turn the heat on it takes about five seconds for the screen to switch to the on mode, same thing with turning it off.I have had no issues with WiFi dropping or issue when connecting when I am away from the house.Overall, for the price I really like this product. It does have a few shortcomings with it but it’s tough to complain for only $60. I recommend it if you're looking for a cheap Wifi thermostat.
UPDATE 2: This unit also has some basic reports it shows how many hours the unit has run and when set, how many minutes/hours if fan only use.UPDATE: I found that this has a built in humidity function. So, I have the house set at 76F but if the humidity goes over 60%, it will automatically cool the house up the 3 degrees or until it removes enough humidity to be under 60%. This is great here in S. Florida. This is so important here to prevent mold.ORIGINAL POSTI followed the directions for wiring exactly, and when I finished; my A/C was blowing hot air. As the house was now about 87 degrees, I considered uninstalling it. I called customer support, explained the issue; and the tech had me send a picture of the original wiring to Emerson's support email. Within a minute, he had me turn off the breaker, change the wiring, and restart the system, which now blows cold air. I'm also controlling it with my apple devices (Siri works great to change temperature).Bottom line: If you have an A/C system with a heat pump (like I do in South Florida), there are two sets of wiring labels (see picture above). Since the wires are put in at the top, I used the labels there. But, you need to use the BOTTOM LABELS. In the picture, you will see the top and bottom are slightly different, so the White wire was W/E instead of W2; and the Orange wire was O/B instead of W. He also had my change a couple settings in the thermostat program (the result of that change gave me an "auxiliary heat" display, just as my original Honeywell had). So, my recommendation is to take the picture of the original wiring; install the thermostat housing; and to then just call customer support to get the actual wiring instructions.
I am so happy I bought this. I got a new AC and I wanted something more hi tech than the thermostat that it came with. I also didn’t want to spend $200 on a Nest. I just wanted something simple that was programmable but also worked with Alexa. This is it! I actually did my research and found this was better than the equivalent Honeywell thermostat.1. If you have both central air/Heat you do not need a C-wire. I live in a condo and they were having problems with the c-wire so I told them to just install it without it, and it still works perfectly. It does have AA batteries that I will have to change eventually but that’s fine.2. I love that it works with Alexa. I like it colder at night so I set up a routine, I tell Alexa “Good Night” and she shuts off my lights and turns the air down to my desired temp.3. This thing has GeoFencing! I thought I would need to program it for weekdays but this is even better. Every time I take my phone 3 miles away, it automatically raises the temp 3 degrees and then lowers it again when I’m back within a 3 mile range. So if I’m just walking my dog or running an errand in the neighborhood it won’t adjust unnecessarily and only does it when I’m gone for longer periods.4. Also has programmable schedules for those who choose this. I just use Alexa and Geofencing so I don’t even have to use this feature.5. I think it’s prettier than the Honeywell and the Nest. I like that it’s white and has a white glow on the screen so it looks better on the wall. The Honeywell has a green light apparently.6. Optional Humidity control. You can set it to a certain humidity percentage and it will overcool a couple of degrees to reach your humidity level. I loved this at first but it didn’t work for me because it was doing it even when I was away and I would rather it just keep the temperature that I wanted instead. But this is a great feature if that is important to you.7. 100% control with the Sensi app. I can adjust my temp from my bed, from work, from my car, while on vacation . It’s amazing. I honestly have not even had to touch the actual thermostat since it was installed. And the fact that you can have Alexa control it and tell you the temp inside and outside is awesome.8. All of these features are optional. You can turn them on and off in the app and cater the system to your family’s needs. Oh and do you have kids or a pesky family member that keeps changing the temp? You can actually lock the buttons on the actual unit from the app and use only the app.This does not have room sensors and it will not learn your schedule or figure out what room you are in or anything like the Nest or other thermostats do. But if you are like me and live in a small space then those features aren’t necessary and with the Geofencing, even if my schedule fluctuates, it will still only adjust if I’m 3 miles away no matter what my schedule is.Overall I say this is so worth the price. I should have bought this a long time ago. I am very happy at the moment but I will come back and update the review if anything changes.
I have to say that anything that has to do with electrical, heat, A/C, wires, etc. makes me nervous. I wasn't sure if I needed to hire a electrician to install this and so glad I didn't b/c the installation process literally took 15-20 minutes. If you go online and search this system, you'll find a lot of installation support and people talking about the installation process. Follow the instructions and the key is install the app first. The app itself will pretty much walk you step by step. I image the tricky part for people is determining if they have c wire or not. If you don't, it's probably a good idea to research more if this system works for you using pure batteries. I chose this thermostat b/c of the reviews and the size. It pretty much was the same size as my non-wireless honeywell system. A few things I've learned that I feel will be helpful for people purchasing this to install it themselves:1. Remove the cover of your existing thermostat and it should tell you if you have a C wire or not. If you do, there will be a wire that is plug to the label C. If not, you don't.2. The system works only on 2.5 gHz vs. 5 gHz so if you have both, make sure you program your system to connect only to 2.5 gHz and remove any auto-connect to 5 gHz even if the option comes up.3. Create one account and if others in your home want to remotely use the system, they cannot create their own account and add this or not, you will all have to access this one account linking to this system4. Understand the settings. You can control how sensitive the thermostat actives. There's a cycle rate setting. Fast cycle rate = tighter temp. control and shorter on/off cycles and slow cycle rate = wider temp. swing and longer on/off. I find that the medium works for us.5. Should your wireless, phone app, or remote access run into an issue, the system still works. You just have to do everything manually. Note: if you set the system on lock and only able to control via the mobile app., that may be an issue. You are stuck with how you last set the system. I'm sure there's a override manually and I hope I never find out. I don't have mind set to lock.If you are looking for a fancy thermostat with tons of different data readings, this is not it. This is pretty straight forward and simple. Tells you the temperature the thermostat is reading at, your choice of your temp setting, the humidity percentage, and whether the system is currently running or off cycle (blue background if currently running, gray is off).Highly recommend this system for the price and ease of use.
