Rated 3.0 out of 5.0 by JAM Requires too much personal information
It was easy enough to install and register, but there is no need for the detailed personal information required to get access to my thermostat over the internet. Otherwise I would have given it a better rating. There is no need for an exact street address (which Honeywell requires!) and many of the required "security" questions attempt to eke out more personal information.

Rated 5.0 out of 5.0 by Cshoes Recirc function did the trick
I helped my Father-in-Law select a thermostat that has the Recirc feature into a summer condo. The condo construction is a bit odd in that there isn't any ductwork. The funrace/A/C blower sends air into the crawlspace and the air comes up the floor registers. After spending a ton of money on encapsulation of the crawlspace to honor the warranty terms air needed to be circulated. Since they only live there part of the year (didn't even go there last summer) the thermostat would be set for minimum utility use when they are not there thus less circulation. The recirc feature on this product has dine the trick. Upon inspection of the crawlspace and the overall air quality we are very satisfied. The only negative I see is there is some complexity that we didn't need and had to pay for. No one cares that you can change the color of the display in our case. Frankly we'd be even more happy if it was as simple as Fan on/auto/recirc on a manual switch. When shopping we could not find this simple an offering so settled for this one.

Rated 5.0 out of 5.0 by Warpedscout Works if you research it
Only thing I had to call about was a power wire that support helped find and connect. Had this on my home since October 2013. Someone here said it did not have an automatic mode, it does. Set to automatic And fan preference, select heat and cool points and walk away. Phone app easy to use and works anywhere I have cell service. Read the manual and is easy to install and operate. Have had no problems with this product! Only problems I have seen is users do not research product to their system and either read installation instructions or have a professional (or kid that is technically competent) install it!

Rated 5.0 out of 5.0 by Jobi Had the Honeywell RTH9580WF 2 Months
I had a new HVAC installed along with the Honeywell Wi-Wi Smart RTH9580WF Thermostat in early June by a HVAC contractor. I registered on the Honeywell site and added the App to mine and my wife's IPhones. Thus far, Absolutely Great! When we depart on trips, we turn up the temp and about an hour out from returning home, we return it to our normal cool temperature from the IPhone. Arrive in comfort... & SAVE MONEY. No more getting up to adjust temp. up or down at home, just pick up the IPhone and make the adjustment. Convenience all around. I was skeptical about losing my Wi-Fi connection & having to reset but so far no problems. Lost our electricity twice for short brief periods during some southern thunderstorms but as soon as the electricity came back on and the router was back up; so was the thermostat. We love it , hope it stays that way!

Rated 1.0 out of 5.0 by Jay NOT SUCH A SMART BUY!!!
Customer service for Honeywell was horrible to begin. No answers to my questions but doing some research and reading reviews my superstition was verified. The thermostat tries to maintain the set temperature with very small difference in temperature possibly less than 1/2 a degree. This causes my A/C to cycle on and off way too frequently. Since installing this thermostat, the A/C will cycle on and off an average 10-12 times per hour during the day and 6-8 times during the night. Talk about wasting energy!
Ideally the temperature Span or Differential setting with the factory default setting being +-1 degree before cycling as most thermostats. Honeywell knowing this has yet to correct the issue. If this thermostat was made with the intent to save energy I think it has failed. I will try to return the thermostat asap but I bought about a year ago but just installed it because my house was under construction. What a mistake in purchasing!

Rated 1.0 out of 5.0 by GoDarkBrightly Design issue regarding screen protective mode
Found the thermostat to be very competitive. I formerly used competitors thermostats in my CA home but selected the Honeywell as I found our household's non-traditional and variable schedule did not lend itself to a learned programming approach. The instillation of the product was textbook and when installed in a bedroom the selection of a coordinating and subdued color screen along with reduced backlight settings were just perfect for a tranquil sleeping environment. THEN 2AM, the screen automatically goes in to a screen preservation mode which overrides these settings and floods the room in stark bright light. A screen saver that goes bright not dark. Solution get up, touch screen to the Home button and wait for the screen to resume your program settings. Oh, manufacture says no design flaw intentionally programed that way with no cancel option or time variable on screen saver option. If you don't sleep between 2am and 3am should work for you.

Rated 1.0 out of 5.0 by MellyMel Poor quality and customer service.
Installed on a 3 wire heat (gas furnace only) system. It was easy to install and setup and after some searching their website did recommend installed the "G" wire on the "C" terminal at both ends.
After 4 hours the thermostat shut off completely and had to be pulled off, pushed onto the mount to reboot (or reset the circuit breaker). It came up, ran for a few hours then died again, permanently. No way to revive it. Attempted to call customer service but after 30 minutes on hold gave up.
This was an online order from Home Depot and the local store was happy to refund the cost so I could buy a Nest thermostat.

Rated 1.0 out of 5.0 by Marcopolo Not sure if it is a Honeywell problem or a Home Depot problem
I bought this product. It was missing the back plate and had registration for two unit in the box. Exchanged the unit and the new one is deffective. It will not find any wifi network. Again I am not sure if it is a Honeywell problem or Home Depot problem........Contacted Honeywell and they blamed it on my Internet provider......It does not see any wifi from my hotspot or my neighbor wifi that all my other devices see.
Maybe I got two units that were returned to Home Depot and we're just restocked or maybe the problem is with Honeywell......Just don't know

Rated 5.0 out of 5.0 by CSelil Simple, Functional, & Attractive
Installation was SOMEWHAT easy. Apparently it is VERY easy to short out the connecting wires (assuming you're installing this yourself). Other than that, following the provided installation videos, everything was very straightforward. The device itself is very attractive. It's large enough to be easy to read and operate, but not so large that it's taking up a large amount of wall space. Set up was very easy. Operation is VERY easy. It's very nice that I can use the app to control the a/c as well. Ultimate laziness ensues when I'm downstairs reading on my iPad and want to turn the a/c down. Why walk up the stairs when I can just hit a couple buttons on my iPad. Overall I'm very pleased with this product. Only note: make sure you don't allow your "C" chord touch *anything* as you could short it out and have to replace a fuse.

Rated 1.0 out of 5.0 by Dave Made my bill go UP, put extra wear on my system, and Honeywell Customer service is TERRIBLE
Bought this unit in June hoping to increase the aesthetic appeal along with improve the efficiency of my system by adding in "programmable days" function. Spent the $200 on this product and at first I thought it was really neat. Who doesnt love something color and touchscreen.... Well, then issues started happening. The thermostat would kick the outside compressor on but not the air handler intermittently. I would come home probably once a week to a HOT house and find that there was cold air coming out of my INTAKE vent and the thermostat would show the temp was 7-8 degrees above the "desired temp." I thought it was a fluke, reset the thermostat and then what do you know, now the compressor kicks on and off like it should, but it now runs my fan inside the home almost continuously. It speeds the fan up, then down, then up, then down. EVEN WHEN THE DESIRED TEMP WAS REACHED.
I called about this issue to Honeywell after 2 weeks of emails telling me that "my system was messed up" and "operator error" and the response I received was nothing short of amazing "Sir, your system is failing, you need a contractor out there." So you are telling me that I should have to pay a tech to come out and diagnose your faulty unit at MY cost??? The 5 year old system is in fact not failing, I replaced the "upgraded" thermostat with the original and ::bing bang boom:: the system works 100% perfect as it should....fan and compressor kick on and off as they should. I call Honeywell back about the issue and explain to them that after much troubleshooting, the issue is with THEIR unit. They deny and deny again that it could be their issue.
After 2 hours on the phone, I finally ask for a refund, they say there are no refunds given at the corporate level. I then ask for a replacement unit, they hang up on me....they call me back a few minutes later and connect me to a supervisor who tells me that she will NOT send me a replacement because it isnt their "way of operating business."
This was by far the worst customer service experience I received from any high cap company and would discourage ANYONE from using their products for fear that something goes wrong and no available common-sense retribution.
I was able to return the unit to the home depot about 2 weeks ago and tried a brand new unit thinking that I could blame it on a defective unit. That one exhibited all the same issues with the AC FAN by not letting it spool down completely when the AC compressor shuts off, running the fan for an extra 5-10 minutes each time the compressor is kicked off. This thermostat increased my daily usage by almost 1$ a day (2$ on the hottest day) increasing my power bill by over 10%. There are NO energy savings to be had with this unit. ***DO NOT BUY THIS PRODUCT***

Rated 5.0 out of 5.0 by 1MarcD Very Nice Product, March 13, 2015
Followed Quick Start Guide, and within 30 minutes thermostat was up and running. Followed all the prompts. Within no time of loading thermostat's Mac address and ID, it found my network. Typed in my p/w I was able to communicate with their app. No hitches for me. Scheduling was straight forward with the option to choose help if needed. Outside temp is a nice feature. Thermostat did an update with no hick ups. I was able to match my decor as well. Many options to use if needed, and easy to get to them. Honeywell did very well with this thermostat and instructions. Hopefully one day they will be able to control modulating furnaces.
Note 1: this thermostat was offered cheaper at a competitor. The staff at Home Depot were more than happy to match the price plus give an additional 10% off after verifying it. Saved me an hour and half driving. Great purchasing experience at my local Home Depot.
Note 2: if you purchase this thermostat and a few others carried at Home Depot, Hydro One will also give a rebate of $100 if purchased before March 27, 2015.

Rated 5.0 out of 5.0 by GeriC Great product!
We purchased this Honeywell thermostat for two reasons: to be able to monitor the temperature when on vacation and because of the fan recirculation feature. My husband would have had to add the "C" wire but with our house layout it was easier for him to run new wiring and relocate the thermostat. The installation went quickly and once installed he left it to me to do the set up. It only took a few minutes to do this thanks to the guided steps. We have been using the thermostat for about 10 days now and love it. We haven't had any issues with wifi connectivity and if you want to override the programmed settings, it's very easy. We are very happy with our purchase and highly recommend this thermostat.

Easy to install, no need to read the enclosed manual for setup. Nice to look at, no need to change batteries, no need to switch from cool to heat with each season. The fact I will be alerted when the temp falls or rises outside of the range I set gives me peace of mind for my animals while I am away.

Purchased 3 units for a vacation home located in the UP of Michigan, one of the three out of the box did not work, no big deal. Home Depot did the exchange no problem but it was a hassel since HD is located an hour away, but HD took care of everything. Then today from 7:30am in the morning until at least 12:30 (5 hours) the servers crashed for Honeywell. Called Honeywell support two times and they did answer the phone and were nice people to talk about but how terrible is if for a company such as Honeywell to have a server crash that completely takes everyone off line? Lost my turst in Honeywell and these are going back to the store for a refund.

Rated 4.0 out of 5.0 by Michel141 It takes two to make one and Tech support is a jok
I bought the above thermostat and installed it. After the install I found that everything was working in heating (Heat pump and Gas heating) but the thermostat was indicating that the temperature was going down ( I had a digital thermometer installed on the same wall showing the temp going up). So it was not stopping the gas heating. I spent 1.5 hrs with tech support for nothing.
Mu first reaction was to return the thermostat and get my money back. Instead I asked for a replacement. Which I installed and was able to get working in less than 15 minutes.
HW tech support is obviously useless and they might have lost a sale of this thermostat and future Honeywell products.
BTW, after the installation, the new thermostat updated its software from 1.04 to 2.03! Strange since the old one did not even after one day. It was the first question I asked the tech and she said there was no software updates. Obviously, she doesn't know what she's talking about...
I now love the thermostat but I think they could make it better if we could control the humidity with it!

Rated 1.0 out of 5.0 by michele5389 Cannot Get WiFi to Work
I had a professional install the thermostat but we could never get the wifi to connect. Because he charges by the hour, I told him I would call Honeywell and find out what was going on. I call Honeywell three times and waited on hold an average of 20 minutes each time. I am going to assume their technical support is offshored because it was very hard to understand what they were saying. One tech blamed my apple router, one said the thermostat was wired wrong, another said I needed to set up an account and then the wifi would work - really?!

Rated 4.0 out of 5.0 by Slyford21 Product and Wiring
I purchased this item today. Install should have been really easy. I would have been done in maybe 15 minutes. I had the notorious "C" wire issue. Apparently that wire was never hooked up in my home.
I failed to take my old thermostat apart and did not realize we were lacking that wire. Fearing I would have to return the product I did some research. I had a spare blue wire at my thermostat. I hooked that up thinking maybe that would work. Nothing! I was able to find the other end hooked up to my heater and the blue wire was not used in there. Found the slot with the "C" next to it and hooked it up.
Hey IT WORKS now!! Set up was easy. Now I shall attempt to register online and hopefully see how it works the next few months.
The product itself is cheap plastic. At least the back plate is. Careful of the circuit board on the back plate because it will pop out easy.
I have large hands which made wiring this a bit of a pain. I would recommend a set of needle nose to help grip the wires and slide them into place. That is all for now. Ill update in a few weeks after It has had time to work (or not).

Rated 2.0 out of 5.0 by Joeldt Sells stand alone with no other parts.
I bought this after speaking to the Home Depot guy. Stated it was better for wifi and being able to use to adjust on my phone. The cards they have as an anti theft said nothing about the C wire, which you need come to find out. I informed the Home Depot guy that I had a two wire set up (a red and white wire) simple turns the heat off and on and he said not to worry it has the power I need. So I get home try to install it and what do I find? I need to power the device with the C wire or basically a line you use to power off the boiler or furnace with a 5 or 8 wire setup. Look online and there is literally no information or videos for people like me. Everyone assumes you have the 5 or 8 wire setup. Even gimmicks designed around splitting and adding wires don't work on the two wire setup.
So you think that a unit that needs power would at least come with a transformer. It doesn't, and the Home Depot doesn't carry them anywhere except online.
Everything you need is basically online now. I could have bought everything, including the thermostat on Amazon, if I wanted to buy online. I go to the Home Depot for you to carry the things I need right now for the peace of mind I don't have to wait for delivery and if it damaged or not the right product it's simply a drive to the store.
So I bought a 200 dollar thermostat with no power cord and basically have to rewire every thermostat in the house and ad a vac transformer off boiler. If I do go with the plug tranformer online then I have to wire in an outlet to hide the wire.
Need to figure out a way to power these things with two wires. Just leave it on the shelf folks and avoid a head ache.

Rated 1.0 out of 5.0 by CJa9489 I Bought This To Reduce My Utility Bill, Not Increase It
The quality of this unit is good, problem is that it will not let me stop it from using back up/aux heat. I have an electric furnace and as many of you know its extremely expensive to run. My heat pump has run just perfectly in sub zero temps and not once did I need aux heat. Ever since I put this in it constantly uses aux heat and its 35 Degrees outside! Instead of seeing a decrease on my utility bill I saw an increase in warmer weather than I did with my old $15 Honeywell. I will be returning this and getting either a nest or putting my old system back in. So disappointed in this product. I really wanted to like it.

Rated 5.0 out of 5.0 by drpete Easy set up and to use. Wifi works great!
Read the reviews and ordered it to replace an old battery powered thermostat.
Easy, clear instructions to install the thermostat.
Had a bit of a problem getting it to light up and work, but that was due to the fact the 'C' wire was not properly connected at the HVAC unit. Once I got that figured out, the rest was a breeze.
It is easy to program, and use the wifi app. I love that it can switch from heat to cool as needed.
The only issue I have is that the touch screen does not dim or go to a 'sleep' mode. That means the display is always on. Even though you can change it to a wide range of colors you may not like the thermostat display being a part of your home or office décor.

Rated 5.0 out of 5.0 by BigGuy Finally! A thermostat that I can read!
A bit pricey, but I am very happy with this thermostat. It took me a couple of tries to get the wiring right. It was really just a matter of taking my time to map the old to new without panic. I was a bit rushed because I decided to do this replacement on the coldest day of the year. In hindsight, not such a good idea. Anyway, I love the display. It is very easy to read in all light levels. The programming was intuitive and easy. I like the remote access feature (via smartphone app), too.

Rated 5.0 out of 5.0 by AllistonOntario Good product, but some quirks
I decided on the RTH9580WF, but missed the fact it requires a C wire to supply the unit with 24v. Fortunately, it was easy enough for me to run a new 18/5 wire between the furnace and the thermostat, but had to fish the new wire into place.
From there is was easy, I wire it up and did the setup and connected the unit to Wi Fi and registered the device. The front panel was fully functional. The unit did a self upgrade and then found the outdoor temp/humidity kept saying waiting to update... after the upgrade. After a few hours, nothing changed.
After reading a few blogs on the issue, I found the outdoor info actually comes from AccuWeather via their web API. I am not sure what the unit is sending AccuWeather, but found the combination "Alliston" and "L9R 0E2" wasn't working to update the outdoor info on the display.
I change my address info online to "New Tecumseth" and "L9R 0E2" and the outdoor info now appears. Odd, either combination should have worked, but the former did not.
The unit is working great and a good buy for the features. In particular you can control it remotely via an APP, but the fact that I can have the an circulate automatically for periods throughout the day was my main interest, than running the fan 24x7 which gets expensive to do.
Too bad the unit doesn't have a alternate battery option which my old stat had to make it more flexible for locations that a C wire option is not available.

I bought this advanced thermostat to enable easier control of day to day and within day/night temperature change needs - it does that well. It was Interesting in that it wasn't my first choice when I went to the store, however it's physical footprint matched my current thermostat wall location the best. I have found however that it is easy to setup and use & really like being able to control it from my iPhone when I need to make a change to the system when I'm out of town. It was definitely worth the investment!

Had this installed in mid-December and have loved every second of having it! It is so wonderful to be able to set the temperatures for when I have to be out of town, and come home to a house that is comfortable. It can be controlled via a laptop or a smartphone--both work well, but you can also program before leaving the house. Can't say enough good about this product or encourage people enough to get one today.
