Works well with our 5g wifi service. It was easy to install. The instructions were adequate so that I didn't have to use tech support. I like that i can control the house temperature when I am on vacation. Features are good. It is easy to set and I like the manual over ride. It is a bright screen and easy to see at night. One thing I dont like is that you have to take it off the wall to change batteries. (This is common, but my neighbor has a thermostat that has batteries on the side so that you dont have to remove it from the wall.)

The thing that keeps this from being a 5-star product is the unreliability of Honeywell's servers which connect to the thermostat to allow remote control. All communication between apps and the thermostat are routed to Honeywell's servers, which are frequently unresponsive. I know it's not a local problem because it occurs with multiple thermostats in multiple geographic locations simultaneously. The worst part about it is that you don't get any kind of failure message - it acts as if everything is fine and gives you false readings so you think it's working. Here's what happens: You use an app (web page, phone/tablet app, or Alexa) to change the thermostat setting, and Honeywell's servers report that the command was executed. In reality, the servers don't actually send the command to the thermostat - the command just gets queued. If you use the app to query the current thermostat settings, Honeywell will tell the app that the current settings are the ones in the unexecuted command rather than actually reading the thermostat itself. So you will think that the thermostat is set as requested, but in fact it was never changed. Then, hours later, Honeywell will eventually send the backlogged commands to the thermostat, overriding any manual adjustments that you may have made in the meantime. So you can never rely on the thermostat to be where you set it, even if you set it manually. During those times when Honeywell has their act together, requested changes are made with seconds and it's very convenient. Unfortunately, they frequently have problems as described above, and you may have to wait one or more days before they get it working again. These problems are well known and documented in internet complaints going back a long time. So it's not a rare, one-off problem. The potential of this product is great, and it's wonderful when everything works. But it's ruined by the frequent problems and the fact that it never lets you know when there is a problem - you just discover on your own that the thermostat isn't where you set it, and you never know when a backlogged command is suddenly going to come through and override your manual setting. Update 1/20/19 - The problems with the Honeywell server seem to be happening more often, with longer outages. Several months ago they sent an email to their customers apologizing for the problems and promising that the problem would be fixed ASAP. That never happened, and there is no reason that they will ever get their act together. Consequently, I'm downgrading this review to 1 star and I'm now looking for another, more reliable brand. Sorry to say, this thing is an expensive waste of money since Honeywell can only deliver empty promises instead of reliable service. Update 1/21/19 - As if to prove my point, Honeywell just sent out another email today. Now they're saying that their continuing outages will be intentional in order to facilitate unspecified "upates". In other words, they're aware of the problem and it's not going away anytime soon. I really recommend you go with a different brand. Here's the relevent excerpt from their email: Our services will undergo planned maintenance over the next few weeks. Start Date: January 22, 2019 We’re performing an update to our software and services to improve your experience and maintain your security. Our servers will undergo maintenance over the next few weeks, and you may experience brief intermittent connectivity. Our updates will begin taking place on January 22, and run throughout February. The downtime will be used to maintain the platform, perform upgrades, and help ensure the continued integrity and security of our services to our users. During this time, your thermostat will continue to work, but you may temporarily experience an inability to remotely manage it via your app. Update 7/6/19 - In case you were wondering if Honeywell ever got their act together, the answer is still "No". Six months later, the problem still exists. So much for the so-called "improvements" that they promised back in January. Their servers are currently down, and attempts to connect result in the following error message: "Server Error in '/portal' Application. Runtime Error. Description: An exception occurred while processing your request. Additionally, another exception occurred while executing the custom error page for the first exception. The request has been terminated. " Seriously, I recommend you go with a different brand. Honeywell is hopeless.

I bought three of these because I wanted remote management capabilities for the temperature in my house. Why three? House is three stories, each floor has one. I went with this wifi capable unit mainly because of the look and it is made by Honeywell. I considered Nest, but I don't need or really want the learning function. I also think this looks better, but that's just me. Most newer (not really that new either) or fully remodeled have a C wire. Just how it is to support digital thermostats. Installing is fairly simple, the instructions are very helpful and include multiple setup possibilities. I do have an issue with the back plate, it is very flimsy so any pressure from the multi-conductor cable will warp the plate and cause the unit not to be completely flush with the wall. Might just take a bit of a soft touch to move things around appropriately to line up right. The thermostat looks fantastic, it is very modern with the silver frame. The color options are pretty nice also, I stuck with the default though. Again, just my opinion. There are plenty of simple and complex options which can be changed through the thermostat itself. Daily schedules, ability to set the thermostat to be the temperature you want at certain times (figures out how long it takes to change the temp), brightness adjustments, color, the list goes on. Unfortunately, almost none of the options and settings can be adjusted remotely. Hopefully this will be coming in time with app upgrades. The schedule can be set to have a heat and cool setting, but so far it appears to not work. I think it only picks which ever mode the thermostat is actually set to, it does not seem to be smart enough to switch itself. Maybe I'm wrong, but when my living room was 60 degrees most of yesterday morning, that tells me different. Again, should just be a firmware or software update to work properly. I did have one thermostat switch to heat from cool at some point a couple days ago, but it doesn't seem to switch right when it is needed. The LCD screen looks great, but doesn't work that great. I am probably comparing it unfairly to a cell phone touchscreen, but the touch sensitivity difference should not be this great. It makes the thermostat itself more difficult to change settings. Overall I am very happy with the unit, I will get each one set up how I want, it will just take time. The main reason I bought this was to change the temperature remotely, which works great. Definitely recommend, even with limited remote management of items outside of heating/cooling.

I had a standard, basic "Dumb" Honeywell for many years and worked perfectly, although I had to manually change settings from the basic 5/2 day schedule to override them. Having Alexa, I wanted to have the ease to change it via voice as well as when I am not home, so I bought the "Smart" Honeywell. After a week, here are my pros and cons: PROS - INTERFACE: Despite what other reviewers have said, I find the interface intuitive and just fine to configure the device. - TOUCHSCREEN: I had none of the horror stories about the touchscreen, listed throughout these reviews. The interface worked surprisingly well and I never had to push anything more than once ever. - SIZE: The thermostat is surprisingly small, compared to my "Dumb" Honey, and I like it more. - TEMP: The temp has been spot on. - DOCUMENTATION: The documentation is complete and most DYI'ers will have no issue following them. - WIFI: Zero issues connecting it to my Wifi. - ALEXA: Zero issues integrating with Alexa. Voice control worked instantly after integration. - INTERFACE: One of the reasons I chose this one was because unlike pricier options, this one shows the external temp and humidity which is a great quick check without having to look anywhere else to verify. - REGISTRATION: Registering the device with the Honeywell website was easy. CONS - WIRE CONNECTORS - Having installed many thermostats, this one was easily the worst and VERY delicate to insert wires. I can see why many consumers, even experienced ones, broke the terminal connectors when attempting to insert them. There is VERY little room to work on the wall plate, and there are no screws like all the others I have ever installed. As a result, here is what I found. First, if you push the first wire in too far and forcefully, the other connectors will be "open" and won't accept the next wire. The next connector will be "loose" and never grip the second wire, and the FIRST one will fall out. I had to take a tweezer with a bent end to "reset" the first connector and then all the connectors reset and I could begin again. (I was ready to return it.) Second, on my next attempt, I realized that you insert a wire until you feel resistance and then "gently" push the wire in like .25 mm (barely nothing) until you feel the slightest click on your finger. Believe it or not, that small amount is all it takes to grip the wire securely. Start on the top of each side and work down gently until all the wires are installed. - FAN: Strangely, the "Dumb" Honey had "ON", "OFF", "AUTO" but "Smart" Honey has "ON", "AUTO", "CIRCULATING". As a result, I have to trust the thermostat to run the fan on its own and I cannot turn if off completely, short of turning off the heat or A/C. At this point, the fan seems to be following a more "intelligent" function related to the heating and does turn itself off when it sees fit. -HUMIDITY: Although the temp is spot on, I have 2 humidistats in the house that are both consistent by the humidity percentage on the "Smart" Honey seems off by 5% and varies from the other two. The thermostat has a configuration setting to adjust the default up or down by degrees you choose, but I have fiddled with this setting and have not seen a consistency in "Smart" Honey with my other two humidistats, one which is 5 feet away from "Smart" Honey. After a couple of attempts, the "Smart" Honey seems to lag on internal humidity value, while at other times, it's showing the same value. Overall, "Smart" Honey has definitely won my affections with its verbal attention to my requests and interface. As "Dumb" Honey sits on my counter, dejected, I have assured it that I am keeping it as a backup just in case this new Honey goes bonkers, breaks or increases my utility bills.

I have two of these Honeywell Home smart color thermostats: I purchased model RTH9600WF in white for our home first. I liked it so much that I wanted a second one for our vacation house. At that time the gray one (model RTH9585WF) was discounted $50 less and that’s the only reason I bought gray the second time. I am almost as happy with the gray as I am the white—they seem identical except for the exterior color and (see more below on this): the gray one does NOT have the automatic setting. The gray is actually a very nice metallic silver. It looks quite pretty. I’d even call it elegant. I really like that these thermostats are very easy to install and connect to my WiFi, and they are easy enough to operate without having to read the instructions. The feature I like the most is the ability to set up my planned vacation IN ADVANCE. I don’t have to wait until the last minute to do that before leaving. I just go into the settings under “vacation mode”, select the date and time I am leaving and the date and time I am returning, and the temperature I want to maintain while I am gone. It’s nice to be able to do that well in advance of my actual vacation if I want to. About the only thing I don’t like about the grey thermostat is that it does not have the “automatic” mode that switches between heat and cool when needed in order to maintain the programmed temperatures. You have to set it to either cool or heat and as the seasons change you need to switch from one to the other yourself. The white one DOES have the automatic feature. If I had realized that ahead of time, I would have spent the additional $50 and bought a second white one instead of the grey. That feature is important to me. I do not use the smart color feature on either one of my thermostats. I like the default color of blue the best and it seems to be the easiest for my husband and I to read. The phone app works okay for me and I was able to easily add the second thermostat. I like these thermostats and recommend them. I write honest reviews to help others make informed purchases because I read reviews myself and appreciate how helpful they can be. I hope that my reviews helped you.

While this thermostat may lack some of the modern "smart" features of competing products, its "smart-learning" ability can't be beat. With this feature, the thermostat learns how long it takes to heat or cool your house. It will then start the furnace or air conditioner so the house reaches the set temperature at the time you program. It really works. I installed my first Honeywell smart-learning thermostat 20 years ago. That house had passive solar and radiant floor heat. The house got toasty warm during the day. With a traditional thermostat, it would not cool off enough for the heat to come on until after midnight. However, it took several hours for the floors to heat up enough to actually warm the house. So it would still be cold when we woke up. Then the sun would come out and heat the house to a comfortable temperature before the hearing system could catch up. Basically, then, the heat ran for several hours for no reason. The Honeywell thermostats were smart enough to turn the heat on early in the evening. The floors were just warm enough when the house temperature started dropping to keep a uniform temperature. The thermostats even knew to turn the system off early, so the heating system would not overshoot and make the house too warm. I tried a Nest thermostat at another house (conventional forced air heat and A/C, no passive solar). It worked fine and it looked nice. I never really liked the way it learned my schedule, so I ended up manually programming it. The automatic home/away feature was okay but not entirely reliable. When I moved into my current house (conventional forced air hear and A/C, no passive solar), I gave the Ecobee 3 a try. It looked nice and has a nice interface. I never found the multi-room sensors that useful. The main thermostat tended to lose contact with them, perhaps because of the size of the house (aren't they supposed to be for larger houses?). They did help some rooms that don't heat or cool enough maintain a better temperature, but then other rooms get too hot or too cold. I found it better just to find a temperature at the main thermostat that keeps all of the rooms at close to a reasonable temperature. Plus my system actually ran more with the Ecobee, trying to get those outlier rooms to the set temperature. What killed the Ecobee for me is that it almost destroyed my air conditioner. It worked fine all summer and for the first month of the heating season. But then one morning this terrible rumbling started coming from my roof (where the A/C unit is mounted). The Ecobee was trying to run my air conditioner in sub-freezing weather. Although it was set to heat, it would cycle the A/C on. The A/C would shut itself off, so as not to destroy itself, then the Ecobee would cycle it back on. I spent a lot of time on the line with customer support, who eventually concluded that the unit was defective. They offered me an RMA, but I couldn't trust that it wouldn't happen again. So I went back to the Honeywell smart-learning thermostat. It took about a day for it to learn the heating times for my house. You can't set the temperature differential for cycling, but it keeps the temperature even to less than a degree without excessive cycling of the unit. For cooling, I set the thermostat to 73 F. It never moves off of 73 once it reaches that temperature. Programming is easy. You get four temperature changes per day, like a traditional programmable. That is plenty for my needs. The touchscreen and app interfaces make the programming easier than with the older thermostats. Temporary and permanent holds are easy to set - just change the temperature and make it permanent or set a time when it should revert to the schedule (although that appears to be the time the system comes back on - it does not appear to use smart-earning to hit the programmed temperature at the time the hold expires). Changing settings remotely with the app is also simple. So far, I don't miss any features from the Nest or Ecobee. The Alexa interface isn't very good, but even with the Ecobee I found it more of a gimmick than useful. I haven't tried using IFTTT for additional controls yet. The thermostat can be set to either home or business mode. The business mode has some additional programming options that would also be useful for home use. However, smart-learning is not available in business mode. I don't see why - if any developers are reading, please add smart-learning to the business mode. Make it an on/off option if necessary. The one negative is that customer support is terrible and non-existent. I installed on a Saturday and had an issue. I tried to call and got a message that said due to high call volume the call could not be answered. It then hung up on me, no chance to leave a message or anything. I went to the web site which offers live chat. There was a message that chat was down and I should call. I tried email and eventually heard back after a week, but the suggested fix was something I had already tried and described in my original email. The issue, in case you run across it, was that the thermostat would say "waiting for equipment" while the room temperature was well outside the set temperature. Eventually the A/C would turn on, run for a few minutes, then turn off and repeat the cycle. It may have been user error (I pulled it off and reinstalled), or it may have been something related to the smart-learning system doing its initial learning. But either way it resolved itself that day.

The overall product works well. The menus are somewhat easy to figure out and it has good features for locking people out of most settings if you need to, as well as being able to dual control heat and A/C. After installation you need to let it settle as the heat from your hands will quickly throw the temperature sensor off. Let it sit for 30 minutes before you worry that the reading is inaccurate. As for installation, you need to be careful for a few reasons. Firstly, the hole for the wiring is small and the overall space between the mounting plate and thermostat is minimal. You cannot have any excess wire or the plate and thermostat won't connect correctly. Secondly, the plate is flimsy so you have to feed your wire back into the wall after it's connected, otherwise the pressure from the wire will bow the mounting plate. Finally, the clips for the individual wires are flimsy and break easily. I bought one unit brand new and one used. The used one came with a broken clip so I returned it and the new one had a clip break on me during installation. Be careful! Overall a decent product and easy to connect to internet, just be careful as installation is a bit of a pain and the clips break easily.

A very nice looking, easy to operate thermostat. It's easy to program and/or check via the phone app, the web site, or of course the face of the device. The many options for setup and operation can be a little daunting, but it's great to have those options. Once they're selected initially, there's little need to revisit them. I got this thermostat to replace my 18-year-old Trane programmable one. Both the Amazon product description and Honeywell advised me (before and after the purchase) to check with my local utility for possible rebates on smart thermostats. I did that, and factoring in the rebate, the thermostat was an amazing bargain. In addition, a wi-fi capable thermostat like this one may make you eligible for thermostat response programs offered by some utilities. Installation was slow at first; I had a problem determining which wire in my home thermostat wiring served as G - ground; my wiring didn't have a "G". Turned out the wire I needed was available, but it wasn't immediately obvious or easy to find in the Honeywell instructions. Don't get me wrong - Honeywell provides a lot of help related to how to wire the device; it just took me a while to track down the information I needed for my particular wiring. Once that issue was solved, the installation went smoothly. A feature that is particularly nice is the thermostat's learning ability. With this, it is able to begin adjusting to a scheduled change in temperature ahead of time, rather than waiting until that time arrives to begin changing the room temp. I do not use the voice assistant feature, so can't comment on how that works. As with most smart thermostats, this one supports both heating and cooling functions and can be set to automatically switch between heating and cooling as temperatures call for. One feature that I would not pay extra for, given the choice, is the customizable color for the backlit display. I played with that at first, but once the thermostat is in operation, I find I pay little attention to the color of the display. I would have been just as satisfied with a preset non-adjustable display color. All in all, I'm very pleased with this thermostat and would not hesitate to recommend it.

I have reservations about giving this five stars, but..... it is a beautiful thermostat that was easy to install. It controls perfectly. The HVAC guy who replaced my air handler told me get a Honeywell. I wanted one that auto switched between cooling and heating. We also wanted a nice display. It does both. The temperature display is huge. I can read it across the room in the dark. It also can be controlled from multiple smart phones and computers. Pretty handy if you are in bed or traveling. The connection plate has a good layout that is easy to use, read, and get wires to. Big plus! Once you snap it on the plate it is a bear pulling off again. You better have secure mounting screws or you will pull them out. This looks like it does not have battery back up, but uses capacitors. They won't keep your program for a year, but probably a few weeks without power, and you never have to change them. I think that is good enough. So why lower marks. First of all I had to call customer service for advice. I was on hold for an hour and a half! That's pathetic. I think after five minutes customer service lines, particularly ones in India, ought to start putting money in your phone account like a reverse 900 number. By the time I got this lady from Punjab online I had read the rather thorough manual cover to cover and figured it out. So here were the problems. The setup never talks about automatic switching between heating and cooling. Plus it is not on the mode menu. No, you have to go to preferences, then advanced preferences and in there you can turn it on. It is way back in the manual.. Why do they want to deter you from doing one of the main features to buy a $170 thermostat for? That's BS too! FYI you have to have at least a 3 degree difference between heat and cool settings. That seems reasonable. This is our third Smart WiFi thermostat. We had a Nest in our old house. They are really nice, but sell your conversations from the microphone to the highest bidder. The nest is cake walk to set up. The other was a refurbished Emerson Electric that could not turn on the emergency heat. We returned it. Both this one and the Emerson read the room temperature way high. Like 4 degrees high. What is that about? We can read the temperature in a crater on the moon from Earth within a tenth degree, you can't get this right?Anyway they have an adjustment in the settings to correct this. This one was off 4 degrees. I mean I am an instrumentation engineer. I have got more thermometers than NASA. I know what it should be. The problem is they only have a plus or minus 3 degree adjustment. I think it is in degrees Centagrade (1.8°F), because 3 degrees overcorrected for the 4 degree error. I dropped the correction to 2 degrees C, now its perfect I just don't get how they screw this up. It really is a nice thermostat, once you get the quirks beat out of it. We have had it for a few weeks now. I love in more than once I got it working right. It is rock steady holding temperature. If it gets off by more than 3°F low it throws on the emergency electric heating. That happened when I first turned it on and it was cold. I love the external (internet) temperature display. It has text telling you what mode it is in.

Embarking on a journey with a new thermostat felt like being thrust into a modern-day fairytale, where technology and comfort intertwine to craft a realm of perfect temperature. The thermostat, a beacon of promise, promised to usher my abode into the era of automation, a dream where warmth and chill danced in harmony at the behest of my mere whims. With the guardians of customer support as my loyal allies, the path seemed clear, the quest straightforward. However, as in all great tales, a twist awaited. Despite my meticulous adherence to the ancient scrolls—manuals and instructions—the magic of automation proved elusive. My abode remained a realm of either eternal summer or unyielding winter, with no passage between. The scrolls spoke of a schedule, a mystical timeline that the thermostat was to follow, yet the dance between heat and cold remained a dance unperformed. It was as if the very essence of the thermostat, its ability to transition seamlessly from heat to cool, was locked away behind an invisible barrier. Compelled by necessity, I sought the wisdom of the customer support sages, who guided me through a labyrinth of menus, each step a closer approach to the heart of the enchantment. And there, hidden away in the depths of arcane settings, lay the key—a feature of automatic control, the very soul of the thermostat, yet inexplicably veiled and guarded as if it were a secret of the highest order. Why, oh why, would the creators choose to obscure such fundamental magic? The feature that is the quintessence of the thermostat's purpose was not just disabled by default but ensconced behind a veil of complexity, unmentioned in any scroll or tome. This choice, a puzzling enigma, left me to ponder the ways of those who craft such devices. Is it a test of our resolve, a rite of passage for the modern homeowner? Or perhaps a reminder that in a world teeming with automation and convenience, the human touch remains indispensable, a beacon of warmth in the mechanical coldness of our times. In this epic tale of automation and temperature control, another subplot thickens the narrative, adding a layer of intrigue and challenge. The thermostat, our protagonist in this saga of modern comfort, was heralded not only for its ability to orchestrate the delicate balance between warmth and chill but also for its alliance with a powerful mage known in the lands far and wide: Alexa, the voice of wisdom and command. The scrolls and heralds spoke of a seamless union, a partnership where voice could command the elements, summoning warmth or summoning chill with nothing but a whisper into the ether. This promise, a beacon of convenience in the digital age, was a symphony of technology and magic, a dream of living in harmony with the elements through the mere power of voice. Yet, as the journey unfolded, it became apparent that the alliance with Alexa was not as it seemed. The integration, though present, was akin to a distant friendship rather than the promised deep and intuitive bond. Alexa, for all her wisdom and power, could only partially command the thermostat. The native integration, a term that conjured images of seamless interaction and effortless control, was, in truth, a tapestry with threads loose and missing. This revelation, much like the hidden feature of automatic control, added layers to the quest. It was a reminder that in the realm of technology, promises of harmony and ease often come with their own trials and tribulations. The partnership with Alexa, overstated in its capabilities, was a beacon that guided the narrative toward a truth often found in the modern age: that the magic of integration, of different realms of technology coming together, is a journey fraught with complexity, a path that requires patience, understanding, and sometimes, the guidance of sage customer support. Thus, the tale of the thermostat and its ventures into automation, temperature control, and voice command becomes a saga not just of triumph and technology, but of expectations, of understanding the fine print in the scrolls of marketing, and of navigating the realities of our interconnected digital landscape. It's a story that continues to unfold, as we, the seekers of comfort and convenience, chart our path through the ever-evolving world of smart homes. In the end, the thermostat saga was a tale of triumph, a testament to the enduring spirit of inquiry and the boundless patience of customer support. Yet, it leaves a lingering question in the air, like the subtle shift from heat to cool—a question of design, of user experience, and of the journey we embark upon with the technology we invite into our homes.
