Touch Smart Thermostat by Emerson with Touchscreen Color Display, Programmable, Wi-Fi, Mobile App, Easy DIY, Data Privacy, Works with Alexa, Energy Star Certified, ST75 - Black, C-Wire Required

I installed the thermostat at our cabin so we could control the temperature remotely. It's nice to arrive there to a warm place. It was very easy to install, and wifi connectivity is good. It works and looks great. I love the app, it is very intuitive and easy to use.

Great product. Bought the silver because it was $26 lower than the white lol. Bought this device because I needed a day to day heat/cool schedule, not 5 days + weekend. Installation took 10 mins for a standard (non-hi efficiency) 20 year old gas furnace. Luckily there was an unused 5th wire in my thermostat cable that I was able to use for the C connection. the device is very easy to setup and in a few minutes after power on, I was able to set a schedule that took advantage of when we are routinely home or not. The app is very useful, and I now can adjust as needed, and optionally lockout changes from the display. There are also great features like offset adjustments and even a humidity control mode. Highly recommend.

I worked in HVAC for some years prior to entering the new field and have installed my fair share of thermostats. Recently purchased a house and it came with an Ecobee 4. Had nothing but issues with it. Would crash randomly and take up to 25 minutes to reboot, and in general does not carry ease of use. Now onto the Sensi touch. Amazingly simple to install and wire, the app even gives you a guide so you can designate what your previous wiring was at the terminals of the thermostat and it will automatically reconfigure and give you a 2-D diagram of positive wire up the Sensi using your existing wiring. Once wired up, I finished registering in the app and was able to control my thermostat remotely on my phone. Both of the app and the thermostat itself are quality, sleek, simple and is incredibly easy to use. I know there are a lot of high tech options out there, but if you are looking for something that is easy to install, reliable, and really offers most of what you would get when spending several hundred dollars on a thermostat for a flat $100. I highly recommend it.

Can be very difficult, if not impossible, to get it to connect to your home wireless router. After spending 2 hours trying to get this thermostat to connect to my router, I finally caved and tried to get support. The AI support did not address my issue so I called their support phone number. I was on hold for 1.25 hours waiting for a person. We spent about 2 more hours trying everything possible to get it to connect. The support person acknowledged that the thermostat was not compatible with my router and told me to send the thermostat back. I almost did. I did extensive searches on the internet for this problem and finally began to piece the puzzle together. The thermostat only runs over 2.4g. I and the tech knew that. My phone could see their thermostat on 2.4g. However, little did I know that the thermostat has it's own mini-router (network) built in and our phones can see it as an independent network. We are supposed to tell the phone to connect to it. The reason why, I finally discovered, is that is the only way to set the home wireless parameters in the thermostat. However, it didn't work because the thermostat could not connect to the router to attach to the home network to get the parameter prompts, therefore, the phone never got a prompt for the parameters. The tech support couldn't figure that out. He said my phone was the problem. It wasn't. When I finally figured out the real problem, I knew that the router would need to be reconfigured. Google searches returned info back to me that this thermostat has serious issues with routers running in smart mode. Smart mode uses one SSID and password to activate 5g and 2.4g simultaneously. That was one problem. The other is that routers also have guest configurations with other SSID and passwords. However, to use this thermostat, you would need to configure the guest network to see other devices on the local network. That defeats the purpose. Therefore, the only way to get this thermostat to work was to turn off smart mode and configure 2.4g and 5g separately with different SSID and passwords on the router. But that isn't the only problem. You now need to add those two networks to your phone and other devices. And there is more. You need to configure your phone to be on the 2.4g network before running their app to configure the thermostat's network configuration. The phone must be on the same network that the thermostat will ultimately be on. Also, turn off the guest network so it cannot see the 2.4g there. Now you will need to reset the thermostat to begin the process over again to setup the wireless connection. If all goes well, their app on the phone will ask for the 2.4g network name (SSID), password, and other specs that you configured for that wireless network name. If this sound like a nightmare, it really was. I'm a tech person. I'm sure many others failed because they simply gave up. Hopefully this review will help you if you have problems. After the router and thermostat are configured, you can enable your guest network and change your phone back to 5g if that is what you were using. The reason is that the thermostat is now configured with parameters for your router. However, if you factory reset this thermostat, you will need to do this all over again. To make this configuration a whole lot easier, this company should have Bluetooth to connect to the phone to give it your router parameters. A far as the thermostat goes, it works fine. I like it. I will only use the app when I am away so I disabled the app and keep the thermostat's wireless turned off. If you do that and then turn both back on, the app will say that you need to go through the configuration process all over again. That is not true. Simply give it 5 minutes to reconnect. If I was rating for ease of configuration, I would rate it a 1 star (0 if it was possible). Because I like the thermostat and it works fine once connected (so far), I only took one star off. that could change in the future once I use it more. I like that the screen color changes based on if the furnace is running or not running. The display is good and the brightness is very good but not too bright. Ease of use is good as well. I haven't tested the app away from the house yet so I cannot comment on that functionality. Update to review: Since my review I have been able to test its remote functionality. It works. I have also tested cutting power to the furnace to simulate a power outage. When I restored power a half hour later the thermostat came up fine and reconnected to the wireless. With that being said, I did not test cutting power to the router at the same time to see if they would sync, as the router comes up slower than the thermostat. When I select the option to turn off wireless on the thermostat and then turn it back on, it takes about a minute to re-attach to the wireless, not the 5 minutes I suggested in the above review. I disable the app on my phone when I am not away from the house and it works fine that way. If I open the app afterwards, all I need to do is to login to Sensi and all is good, provided that I have the thermostat's wireless feature turned on.

I purchased two Sensi thermostats since it was getting close to heating season and one of my old thermostats died. Sensi was top rated on many sites so I found the best price at the time on sale on Amazon. These are very easy to configure. You can set up lots of schedules and quickly adjust the temperature on the phone app. I did have an electrician do the installation because I did not have a c-wire on the old thermostats. But she simply did the installation and tested it. She said she hadn’t installed this brand before but was very impressed with the quality and ease of installation so she planned to recommend them in the future. I set up the WiFi connection, all the schedules and options in no time without reading instructions because it’s very intuitive. You can change the brightness, set it to dark for nighttime, and quickly adjust the temperature by touch. They’ve been in use for a couple of months with no issues. Highly recommend.

It just works! I had an Ecobee but got tired of all the useless garbage on it. Simple to use, always works from my app. Less is more!

This is the thermostat I wished I would have had all along. Easy to install, easy to read and good looking. The app is great and has a lot of features that I haven’t seen on other thermostats I’ve owned. The temperature settings are right on out of the box but you could do some minor tweaking if necessary. I find it very attractive, I bought the brushed metal unit. I installed it a month ago and not once have I had any connectivity issues; rock solid app. My wife and I have the app on our phones and they both work fine; you just need to share the same user and password is all. I like that the display dims down enough to be able to see it ok without it keeping you up at night because it’s too bright. One of the features I really like is when the furnace is actually running the display background turns orange on the unit and the app. I think it turns blue when the ac is running. I’m really impressed with this unit and recommend it to anyone. The directions are very clear and easy to follow so pretty much anyone should be able to do the install.

I gave it 4 stars only because of a lack of clarity using an Android to set up. But let me digress. First off the product is very good; and mechanically, it's easy to install. All I needed was a screwdriver and a pointy nosed plier to put the wires in. And it's versatile for just about any HVAC system. Shipping was less than a week in TX. In my case, I have a heat pump. I spent time understanding the features of my system (emergency heat, meaning 2 stage air handler but no Common wire at themorstat since I had a manual t'stat). My installer was kind in that they had the common wire spared in the t'stat and I tested that with voltmeter to confirm voltage between Red and that wire that it read the 24 VAC and I knew it was the common. Once I had all my wires properly landed and then turned back on the breakers at the air handler, I was faced with the setup. This is where things got troublesome. I had the Sensi app already installed and a login setup. So the first step is to connect to Wifi. I tried everything I could and Googled for help and no matter what, would not connect. (Keep in mind there are a list of routers that it is NOT compatible with so make sure to check that list before you even start. Go to Sensi website for that list.) So after 20 minutes of fiddling (and I'm a past IT professional) and realizing I had an hour before their support phone line closed, I gave them a call. I was pleasantly surprised that I got through quickly to a lady who was very helpful. After running through the basics of turning Data off on my phone, and making sure I was connected to a 2.4 ghz wireless connection, and that my router was compatible, what I then learned was that there are several steps that are not clear in any instructions. First, when you are in the App and connecting Wifi, you will see the wireless connections pop up and list the available wireless networks. BUT, you have to give it a few seconds and suddenly you see a Sensi network show up. You have to select that as well. Then the t'stat temporarily disconnects the Wifi and connects to a Sensi server and downloads a firmware update and takes a few minutes to do that. Then the t'stat reboots and you are asked on your Android a second time to connect to both the Wifi network and to check the Sensi network a second time. Then you are ready to manually put in your Wifi password twice. And you finally are past that step. Next you go into the Advanced Settings on the touchscreen of the t'stat and to the HVAC setup icon. There you need to know your type of system; heat pump, 2 stage air handler/1 stage outdoor unit. And then you manually choose the proper choices to get the control functions mapped correctly for your system. That went quickly. So the lady spent at least 20 to 30 minutes on the phone with me walking through all of these. Lastly, is the actual temperature setting. At first my temperature readings seemed to be way high and I had to apply a -5 degree offset via the phone app settings to get the temperature in the neighborhood. I had my old t'stat and a kitchen digital probe nearby to compare those readings to the new t'stat. I would say after about 24 hours of use, and the next day, the numbers dropped on the Sensi to where I had to then remove the offset entirely and back to zero, and now it's right on the money. I do like the new auto change feature that will come in handy in TX with 40 to 50 degree temperature swings in the fall and/or spring. If most of what I said seemed scary to you technically, then I would certainly recommend you get an HVAC pro to install it for you.

Dit product is niet geschikt voor gebruik in de EU. Probleem begint al bij het registratie proces, daar loop je vast omdat registratie alleen voor USA en Canada mogelijk is. Het alternatief (Apple home) beschikt niet over alle functies voor optimaal gebruik en functionaliteit. Programma’s (schedules) maken is onmogelijk. Door registratie problemen werkt deze thermostaat (zonder schedules) alleen binnen je eigen netwerk omgeving en niet buitenshuis. (Middels Apple apparatuur geprobeerd het draaiende te krijgen)

So far this thermostat is working very well as a replacement for an old-style analog Honeywell. The touch screen is easy to use, setup and home network integration are a breeze, and it easily connects to Apple Home. The Apple Home app functionality is very basic, but I like having the ability to run automations or use voice commands with Siri. The Sensi app on the other hand has a lot of features, and is well-designed with a pretty intuitive user interface. It’s only been a couple of months but I’m very happy with it thus far. UPDATE: It’s now been over a year. I have had no issues at all. The only time it drops connection from wifi is when the power or internet go out. The app is just amazing. You can do a lot but it’s not clunky or confusing. They just keep making it better and easier to use. One of the best smart home device apps I have ever used. I hardly ever use the touch panel.

Great functional controller that does the basic job expected from a controller. However.... YOU CANNOT USE THE WIFI ABILITY UNLESS YOU REGISTER THE PRODUCT, BUT BUT BUT YOU CAN ONLY USE A USA TIMEZONE.!!! How hard is it in this day and age to include the rest of the world???

👌

I already had a non-smart programmable theromostat, which worked fine, but was nearly impossible to read unless you were inches away, with the room light on. I like that this one is easy to read from across the room (with brightness controls), or right on my phone. Also very convenient to be able to adjust the temp from anywhere and set a reminder to change the furnace filter. Excellent installation instructions! Overall….very happy and would recommend.
