Customer Ratings & Reviews

Okay, I’m impressed. The idea that I can change the temperature in my house without getting my lazy buns up out of my recliner is impressive indeed. But what I like most about this thermostat and its associated Android and iOS apps is their simplicity of use. Also, there are NO BATTERIES to try and remember to change every New Years! Yeah! This thermostat was installed in my 10 year old home with a standard, natural gas, forced air heating and cooling system. My son-in-law installed it for me and he said it was one of the simplest home maintenance tasks he’s ever done. He couldn’t believe the entire swap from old programmable thermostat to the new smart wi-fi thermostat only took him about 10 minutes. He said everything went perfect. He especially like the little wire marking tags provided by Honeywell. A very helpful idea to get everything hooked up correctly. It’s a little odd to think you must have an online account just to use a home thermostat, but it is necessary for your mobile devices to “talk” to the thermostat. Therefore the registration and setup process with Honeywell is necessarily more than just an “I own it” type of registration. You setup an account with Honeywell using an email address and a password. Then you link the new thermostat to that account using two codes from the thermostat. Then you verify that you actually have access to the thermostat by changing its temperature setting to one chosen by the registration website. Sounds complicated, but in practice the whole registration/setup process was actually very simple and most importantly everything went flawlessly. The real benefit of owning this thermostat only becomes apparent after you install the Honeywell Total Connect Comfort app on your mobile device(s). I installed this app on two Android phones, an iPhone, and an iPad. All installed and connected to the thermostat without any problems whatsoever. They all function perfectly and their user interfaces reflect the same simplicity as the thermostat itself. The app is important because without it and your home’s Wi-Fi connection this thermostat becomes just another programmable thermostat, albeit one with a very nice, color touchscreen. This thermostat does everything you would expect from a programmable thermostat, plus much more. But the great thing about it is it can all be done from your mobile device using touch control or voice commands. Honeywell added some nice features that I especially like and wanted to make mention of: First, the Honeywell software updates for this thermostat occur automatically during the night without bothering you at all. Love that. Second, the thermostat and mobile device apps all display the outdoor temperature and humidity. It must pull this localized data from the Internet because there is no outdoor sensor. Third, in addition to its standard On and Auto modes, the fan also has a unique Circulate mode that circulates the home’s air at random intervals totaling about 35% of the time. Finally, if you move and leave the thermostat behind, you can easily delete your Honeywell account. The new homeowners will then see a bright orange button on the thermostat’s touchscreen that says Register Online. Overall, I’m totally impressed with this Honeywell smart thermostat and its apps and I can highly recommend it without any reservation.

WANTED THIS TO WORK, BUT INSTALLER SAID THAT WE HAD TO PAY AND HAVE AN HAVC TECH COME OUT TO CHANGE THE WIRING. DISAPPOINTING - WILL RETURN TO STORE.

I've been researching and checking on these for a few years and I finally decided on this Honeywell. The unit itself came very well packaged and the instructions were easy to follow. I have an older oil burning furnace with only two wires, so no power wire. I had to purchased the "Venstar ACC0436 2-Wire Kit for all 24VAC Thermostats" to supply power to the device. It was all very easy to install and works great! I opted away from the "learning" thermostats and wanted this one because of the easy to use app and attractive display. It works great and I have no complaints. The app is great and easy to setup. It is so handy to have control away from home. I haven't had any wifi connectivity issues yet and I hope this gives me years of service.

The device is defective and I have to pay to correct even though I purchased a warranty

Didn't no how to set up the product. Had to buy a different thermostat

I returned it because I did not hAve a C wire. C wire is needed.

Not so great did not work and had to return it hard to work in app

I had this professionally installed by Geek Squad. technician could not get this to work. Exchanged for Nest and Nest installed easily.

This unit comes with instructions on how to use on a 4 wire system but never worked.

I’ve heard folks say that smart, remotely controlled thermostats such as the Honeywell Smart Color Thermostat are just for the lazy. Nope. They also are for people who have mobility issues, who need to control a system from miles away, or who just want a home that is more comfortable and more energy efficient. I had our regular HVAC fellow install the Honeywell Smart Color Thermostat while he was here for our autumn checkup, so I cannot speak to how difficult or easy it is to install. However, he told me he had put this unit in his own home and has begun recommending it to customers for its ease of use, its tendency to lower usage costs, and the fact that Honeywell thermostats have proved dependable. Now that it is installed in my home, this thermostat has delivered as promised. The first promise kept was how easy it is to get all the bells and whistles up and running, beginning with connecting to Wi-Fi, creating a Total Connect Comfort account, and registering the unit online (all needed to control the unit remotely). Next came selecting the Mode—Heat, Cool, Off, and my favorite: Automatic. I know this isn’t the only thermostat that can select whether to activate the heating or cooling system, but it’s the first one in my house, and now my house HVAC is functioning more like the system in my car. Next came establishing the schedules, and for that this unit has great range and flexibility. You can opt for “I’ll do it myself,” use the preset schedules, or begin with the preset schedules and make whatever adjustments you want. There are lots of combinations and setting options. One thing our HVAC guy urged me to try is setting the fan to Circulate. On Circulate, the fan comes on periodically – without heating or cooling – to distribute and mix the air. This helps even out the temperature and humidity differences that develop within and among rooms between heating and cooling cycles. This not only increases comfort, but also the time between heating or cooling cycles. And, because a fan uses less energy than a heating/cooling unit, that’s money saved. I knew I would like the Automatic feature of this thermostat, but our HVAC folks touted its “smart” feature. I was able to set my old thermostat to maintain a particular temperature for a specific time interval. If that meant raising or lowering the temperature at the start of that interval, the old thermostat would turn the system on a set number of minutes ahead of time – whether it actually needed that much time to attain the correct temperature or not. In contrast, the Honeywell Smart Color Thermostat “learns” how long my system takes to reach a given temperature and doesn’t waste energy turning the system on too soon. Finally, the Honeywell Smart Color Thermostat has adjustable security settings. If you are worried that a child, an impaired adult, or anyone else might change the unit’s settings, you can lock the settings and set a password for access. I guess a talented hacker could override that, but I don’t view my house as a likely hacker target.

It broke during installation and I still haven't received a replacement

This is my first upgrade to a Wi-Fi thermostat from an old Honeywell circular thermostat. We didn't need to upgrade, but it seemed like a good way to save some extra cash. There are a few things I need to address right off the bat for older home owners. Setting up the new thermostat is easy, but you may have some issues if you're hooking this up to an older furnace. Long story short, the previous owners did not splice the heating/AC wires correctly and a fuse blew. I had to get someone to come out and fix the wiring (I am not good with this sort of thing). If you aren't sure about doing it yourself, consult with your local HVAC company. Replacing the thermostat is very easy and I would say that anyone can do this. Before you start unhooking everything and getting excited, make sure you take pictures of your old setup! This will help troubleshoot any problems you may have. As you can see in the attached photo, replacing an older, bigger thermostat might reveal some touch ups you'll have to do on your wall, but that's not Honeywell's fault. The thermostat powered on and setup is very simple. For some reason mine was defaulted to Spanish, but I my limited knowledge on Spanish was enough to figure out how to change this. The display on the thermostat is a good size and easy to read. You can change the colors of the theme to select color palettes and even create your own custom one. You can set up a weekly schedule for your house. You can set the heating and cooling temperatures, set times for when you're home and when you leave for work, and there's a vacation mode that you can set. There are more features, but these are the basics that suit our needs (for now). The touchscreen on the thermostat is colorful and responsive. You don't have to repeatedly tap on the screen for options and it doesn't require pressing with great force. The display is large enough that you can see the numbers and details, none of the text was too small for my eyes. There is also an app you can download for your smartphone to keep an eye on things remotely, change schedule settings, adjust the temperature, and it even has a microphone so that you can speak into the app to adjust settings. The only complaint I have with the app is that it looks too big on my iPhone 6S Plus screen. It would look nicer if the resolution of the app fit into that screen, but this is a minor complaint. Overall, we have not had any issues with this thermostat working on our 30 year old furnace. If you're looking to upgrade to a Wi-Fi thermostat, I would highly recommend this. Honeywell also has videos and instructions online, along with phone support all week in case you need help.

It’s not battery operated and must be hooked into a 24 line you might not have , I didnt

This isn't a good deceive. the wifi didn't work and installing this wasn't easy.

Don’t buy. Bought 2, one stopped working within a year

Had an actual electrician on hand to install and it did not power up. Returned.

I am not really satisfied with this product . Don’t like it .

It didn’t work returned. Software outdated. Don’t buy

I took this back because Inwanted a simpler set up and functionality.

This thermostat has made my life a bit easier. In my house, the thermostat is on the first floor while my office is on the second floor. Now I can use my phone to control the temperature so I don't have to run up and down the stairs all the time. It's also easy to program. Installation was easy since I already had a "C" wire in place that provides the power this needs. It also looks nice - clean and modern but not like some kind of spacehsip.
