RTH6580WF Wi-Fi 7-Day Programmable Thermostat, White

Bottom Line: The installation was ALMOST effortless, and the performance has been rock solid. I'm very pleased by the unit and would certainly buy it again. I, too, had to unplug the unit once during installation in order for it to complete the temporary wifi connection to my android phone. However, that was the only hiccup. Otherwise, the installation went smoothly. In short order, the wifi link to my WPA2-encrypted router was complete, using a 2.4 GHz channel per instructions. For the past month, I've monitored the home remotely to determine if I needed to engage the aux heat strips during unusually cold periods. I currently live 500 miles farther south, and have not yet moved into the home, so remote control of the HVAC was the purpose for the purchase. The thermostat interface is simple and basic, but entirely sufficient. I don't have to mess with it to see the relevant information; it's all there on the main display. As a recently retired electronics engineer, I have an extreme distrust of new technology, because most companies chase the easily-wowed but ignorant masses with pretty bells and whistles at the expense of design maturity and reliability. To a former design engineer for the military, this is a frustrating trend. Similarly, I cannot abide the intrusiveness and privacy concerns over voice-activated devices monitored by Amazon and/or Google (or whomever). You can do all that lazy nonsense with this thermostat, but I don't want or need it. I want and need rock-solid internet connectivity and sufficient remote control for when I'm in a different state and I'm worried that the heat pump won't be able to pull enough heat out of the air to warm the house. And in this scenario, Honeywell delivers. As with all purchases, particularly electronics, there is a risk of buying a lemon or experiencing infant mortality with one or more electronic components. Fortunately for me, I saw no evidence of quality concerns with the device. It appeared well-made, competently assembled, and sufficiently documented. I do urge people to follow the instructions carefully and slowly. I suspect I moved too quickly, possibly doing steps out of order, which may have caused my wifi hiccup. Either way, it was easily corrected with the power cycle and more carefully following the instructions. I have no issues with the phone app. It works fine and allows me to do everything I want to do. It's streamlined, effective, and reliable. Surprisingly, it doesn't annoy with poor design details or irrelevant BS. (Not looking to be entertained by my thermostat. I just want the bloody thing to work and do what I tell it to do, when I tell it, without becoming a new and contrary personality in my life.) In this regard, the app has been a pleasant surprise. In summary, if you are looking for a solid performer and you value reliability over gee-whiz style and the latest marketing fad, then consider the Honeywell RTH6580WF. It's a very good value, delivering full performance at a much lower cost than most alternatives. Consider repurposing all that saved money towards something of greater life impact than a "stylish" thermostat. Good luck.

I purchased a two pack of these and so far am very pleased with their operation. To clarify, the reason the "C" connection is needed is that these units run off 24VAC that is normal for HVAC thermostat controls. They do NOT have a battery backup so that is necessary for operation. Be sure to check the wiring of your old thermostat and use a multimeter to ensure you have 24VAC between RED and COMMON on your existing unit. Wiring installation was straight forward and typical or most HVAC thermostats. As some have mentioned, the Wi-Fi setup is not quite as easy as some apps which simply allow scanning a QR code to add a IOT device to the home network via the manufacturer's app. That being said, carefully following the instructions provided and using a smart phone to add them to the home network is easy enough if you take your time. Once set up is completed via the Honeywell webpage, controlling the devices, setting schedules and notification alerts is EXTREMELY easy on the website (see photos)! Additional features like configuring for use with a heat pump or electric heat, Smart Response Technology (where it learns how long it takes your system to reach a setpoint and adjusts schedule start times accordingly) and Auto Changeover (where the device selects Heat or Cool mode to maintain a certain temperature) are only accessible through the device itself and not available remotely. This makes sense since these settings would only be adjusted one time. For those who are wondering, after adding these units and downloading the Honeywell Total Connect Comfort app to confirm connection, they can be added to the G home very easily from the G home app which allows basic operation control (mode and temp setting). The Honeywell app provides more control including scheduling but notifications can only be set up via the Honeywell webpage. If you are looking for a really good Wi-Fi thermostat solution at a reasonable price from a reliable company, I highly recommend these units.

I'm writing this review at the 45-day point since installation. I'm hoping someone for Honeywell Home Products will read this and intervene. Otherwise, it's going back to Amazon. Why? The unit installs easily and the connectivity to, and access from, the Internet is great. I love that I can control this device remotely, be it in bed at 02:00AM or on the road in another state. But, I do NOT love that this system is not behaving as it first did when I installed it. It is NOT following the program for the Sleep settings, let alone showing that it has any bit of this so-called "Smart Response Technology" (where it supposedly learns from your home and settings so it can start cooling/heating to the upcoming temperature close to the scheduled time. For instance, in my case I have the temp set to 77º during the day and 74º for sleep (11:00PM). The unit should learn to start cooling the home so as to get close to that 74º point AT 11:00PM and NOT start attempting to reach it at the time scheduled. What the unit seems to be doing now is anything but. The house is reaching 78º around 11:00PM because the unit seems to be thinking, I guess. The "Cooling" indicator is flashing on the unit, but the system has yet to kick on. And, when it finally does, it seems to shut off at 77º and does not get its act together, at the least, until I manually override the 74º programmed setting to 72º. And, last night it seemed to start and respect that override, stating in the iPhone app that it was going to hold that temp 'til 07:00AM (the next programmed scheduled time) but at 02:00AM when the system stopped, it had reached 74º and the app showed no temperature override, at all. Mind of its own! I will resume Saturday's contact with Tech Support later today. Let's see where this goes. Update: The unit was behaving as-designed. The issue happened to be that my condensation tube was clogged causing a backup in that line and the shut-off float to be triggered. I'm quite happy with the iPhone App interface, as well. Resideo's customer support/warranty process, though, has a lot to be desired.

I purchased this in May of 2022, and posted this review in December of 2022 after 7 months of use. I had been considering various smart thermostats off and on for well over a year and finally decided to go with this one, and I am glad that I did. I bought two of them, one for each zone. The installation was as easy as it gets and took about five minutes per thermostat. Didn't even need to read the instructions, just turned off the circuit that powers the furnace so that the old thermostat lost its 24V power source (verified by the thermostat losing power on the display). Pulled the thermostat off of its mount, took pictures of the wiring for reference, unscrewed the five wires and the old mounting plate, screwed in the new mounting plate (the screw holes perfectly aligned for both the old and new Honeywell units), reattached the five wires in their appropriate slots, turned the power back on to the furnace circuit and everything worked perfectly. The next step was to setup the new smart thermostat for WiFi, and this took a little bit longer because the process can be finicky. You have to remove the thermostat from its mount for about ten seconds and then put it back in, this helps initiate/restart the WiFi setup process. Then quickly go to your wireless device and join the new thermostat network. Then in my case, I had to manually open a browser tab to http://192.168.1.1 to complete the WiFi setup. If you don't see the new thermostat network or if that network address for it doesn't open up, then you will need to remove the unit from the mount for 10 seconds and then put it back in and repeat the process. A list of WiFi networks should open up on the above noted address, and from there you can join your 2.4Ghz WiFi network. Once WiFi setup is complete, install the Total Connect Comfort app and create an account. You will then need to register your new thermostat(s), all you need is that piece of paper from the box that says the MAC ID and MAC CRC. Once the new thermostat is registered, you will be able to control your thermostat from anywhere with any device. Total Comfort Connect has an app and a web portal that allow you to access, configure and adjust your thermostats. The web portal gives you more options, for example, I could not find an option to remove a thermostat on the app, but you can on the web portal. So if you can’t find what you’re looking for in the app, check out the web interface. While this device gets ~70% 5 star ratings, the other ~30% appear to be largely related to improper installation and/or frustration associated with the installation. The instruction PDF for this unit is 140 pages and could easily overwhelm most people. I have condensed the process into this short review as it related to my install, which was switching from an older Honeywell thermostat to this newer smart thermostat. Note that I already had the 'C' common wire and this was a simple replacement as everything I needed was already in place. Honeywell does log your thermostat settings and usage of your HVAC system and send monthly reports to the email where you registered the thermostat account. They probably sell this information without your personal identifying information. For example, in this report they compare your current month’s usage to the prior month. This includes how many hours you used the A/C and Heat, and how many hours they were off, as well as the average thermostat temperature settings for your home and away schedules. Some people will be opposed to this as a matter of privacy, so beware if that’s you that this is what you should expect. I am big on privacy, but I am not bothered by this enough to refuse to use the product and I will still recommend it to others. I hope this review helps others make their decisions to use or not use this thermostat. My family is very happy with it, and we have so far had no problems or complaints. If this changes, you can rest assured that this review will be updated to reflect that. I like that this new unit is not a touch screen, so there are no smudges, and the screen is much clearer than the old unit. It is really nice to be able to control the HVAC system remotely, to easily setup a schedule, and to easily make adjustments from the app. Stay warm/cool!

I have been in search of affordable, remote access capable thermostats for some time. The Nest is just too pricey for me, especially with two thermostats needed in our two level home. The Nest units sure look nice, in typical fashion as one would expect from their Apple designer pedigree. I even contemplated buying one per year to soften the sticker shock, but the reviews for them had one glaring thing that stood out, and that was the wide temperature swings before heating or cooling started. For the price, I expect a tighter temperature range. The Nest also appears to be better suited to automatically adjustng itself based upon your actual coming and going, while the Honeywell is based solely upon a schedule. If you want a thermostat that will manage itself, the Nest is probably the way to go. In our family, we generally have set times we are at home and away, so the Honeywell works best for regular schedules. Honeywell has three step up models, including the new Lyric, which looks quite a bit like the Nest (which itself resembles the old, mercury switch, round type thermostat). From what I read, the Lyric offers more self managing like the Nest, but is also around the same price. Given the choice between the Lyric and the Nest, I would go for the Lyric, if only because Honeywell has a long history with thermostats, but I am a cheapskate! The next lower tier Honeywell WiFi model has a snazzy color touch screen, with time and outside weather indicator (and probably forecast). While I would have loved to have this model, it was still almost twice the cost of the RTH6580WF. Below that is the WIFi model that has almost the same screen monochrome LCD as the RTH6580WF but with touchscreen functions. To me not worth the slight price premium. So the RTH6580WF was the model for me. One of the concerning things for the Honeywell was the need for a "C" wire, which I assumed my systems would not have available, forgetting about the loose wire left unconnected at my previous thermostats. A quick check with a voltmeter that they were not connected at both ends, made it clear all I had to do was connect the proper terminal at the transformer to have a working "C" wire. Easy peasy and no sparks! Installing was easy, especially with the good documentation included (including labels for each line). Just be sure to disconnect the power to the transformer beforehand. The hardest part was making sure the wall mount was level, which speaks about the simplicity of it all! The wifi connection portion was easy with the included instructions. After a delay for the thermostat to automatically update its firmware, it was on the network. Setting up the online account was easy, just be sure to hold on to the paper card supplied with the thermostat if you are away from the thermostat, as it contains the thermostat information the website requires. The iOS and Android apps are easy to operate and progamming is straighforward, just be sure to press submit or your programming will not go through. The software works via a connection to Honeywell, with no direct control of the thermostat available, from what I can tell. That is a negative to be sure, but it is an acceptable tradeoff, and I believe most WiFi thermostats suffer from. I have to assume Honeywell will be around for quite a bit longer, and with such a huge user base, keep the system up and running. I have experienced a few times in the several months of use that the portal was down, but the system came back up within an hour. I wish the software would provide ore information on times of use and the like, as well as the ability to lock out changes at the thermostat, as my kids have a habit of turning the thermostat settings to extremes of heating and cooling (like turning the A/C on when it is freezing outside). The system can be configured to send messages if selectable temperature extremes are met, but I have not yet tinkered with it enough to verify how well it works. More finegrained control of this would also be an improvement, but I am unsure of the limitations of the thermostat itself as far as this is concerned. The web portal and apps work fine however for sending changes remotely as I have been able to adjust the temperature adjustments made at the thermostat. In all, this is a highly recommended device, with the two in our home working without issue for several months now.

If I could give it zero stars I would. I purchased this thermostat almost exactly 2 years ago this month. I read 14k predominantly positive reviews, but remember reading a review that it only lasted 2 years! I thought what are the odds? Well they weren't in my favor and the thermostat crapped out after 2 years! First I had a problem with functionality but that was because my C wire wasn't connected at the furnace. I called my HVAC guy a friend and he connected it and it worked. Then I tried connecting it to my wifi, initially there was difficulty connecting, I did everything the manual stated but it didn't work. So I called tech support followed the same steps over the phone and it connected. I didn't want anything overly complicated so I chose this thermostat. I'm basically home and increase, decrease the temperature when I want manually or by the app. Which is not great, takes several seconds to connect. Once it disconnected from my wifi, couldn't reconnect so I logged in from their website and reestablished connectivity, it happened again. So the app is meh. It's summer here and it's hot and I don't keep the air conditioning on too low don't like it cold but I came home two evenings ago and it felt warmer than usual. I thought the air conditioner should go on soon and cool off. After a few hours it was still warm so I checked the app to lower it and it was disconnected and couldn't reconnect to my wifi. So I went to manually do it and the display was BLANK! I freaked out as it was so hot and humid. Too late to call tech support so called the next morning on my way to work. They told me to check the voltage in the wires, basically the electricity. I already turned all my circuit breakers on/off the night before and the furnace had a steady red light. I later read that a steady red light was no signal from the thermostat as the number one reason and a few of others like electricity, furnace door is open, pilot lights, problem with the furnace but I knew it wasn't any one of those reasons. When I got home I texted my HVAC guy since I don't have a voltage analyzer and he never got back to me, guess I have to find a new guy, company which will be expensive because he was my sister's ex and a friend...no more! A friend of my mother's knows about electricity and came by today and connected the white and red wires which should turn on the heat of the furnace, it didn't work. Then I read to turn on a/c connect yellow and red and it didn't work. So I thought I needed to call my electrician, but decided to check my furnace in the attic and turned it off then on and viola it went on! Kept the a/c on for several hours until the house was cool, then disconnected the wires. I tried the white and red wires and the heat went on. So it's not electrical never thought it was because everything was working but the thermostat! The warranty is only 1 year so I'm now trying to find a better thermostat, hard to do, pros/cons with many including the most popular round one that didn't get great reviews and I don't like the interface. But DON'T BUY THIS!

We had always had the standard, basic Honeywell thermostat. One of them failed, so I decided to replace both and this unit had great reviews. The installation was just as easy as my basic thermostat (we have basic furnace and A/C and no heatpump), the only exception being the need for the "common" wire, which fortunately had been put in the wall even though it was not connected to the basic thermostats. The red wire is usually your 24 volts A/C and if you connect a volt meter between the red and what you think is your common wire, you will see it showing 24 volts. If you see zero volts, and you know your red wire worked from the prior thermostat, your common wire may not be connected to the common terminal in the furnace control board. Activation and programming was not difficult, and the panel walks you through the process. Just read the directions and follow them in order as instructed. When you first connect the panel for the first time, my furnace fan turned on for a few minutes then turned off, even though the panel said everything was "off". The panel display took about 10 seconds to show a display so be patient. If you get no display after a minute, it may mean you did not connect the common wire or your common wire is not connected the common terminal on the control board of your furnace. The steps included initial set up of time and date, then connecting to your home wifi network, then registering the unit with Honeywell's server so you can access through the internet (you only have to this once for multiple units). You have to register as part of the setup. Once you get all set up, you can see your virtual thermostat controls on your phone simply by logging into the Honeywell server (if you more than one you can see all of them). I don't know if I will use this remote feature much but it works perfectly. You can, of course, also set the thermostat directly from the front panel and the buttons are easy to see. Like other thermostats, you can program by date and times for temp. I set up two units, and had no issues with either one. Only had them a month or so, but so far happy with the results. Oh, and these are WAY less expensive than the NEST thermostats which cost well over $200. I don't have Alexa so can't speak to how it works with that service. I did not have to get tech support so can't speak to that either. A good looking panel and nice bright backlight. I only wish you could leave the backlight on all the time, but that is not an option.

I am very pleased with the unit and it is performing exactly like I hoped, after a month of usage. Its very cool to be able to modify and monitor the temperature setting of my home on my iPhone or laptop from anywhere. Since installing it I have not yet taken a long trip away from home but I know that when I do its going to bring some piece of mind to be able to check in and make sure the house is warm and not freezing up. Scheduling: I really like the ability to set the daily/weekly schedule from the web interface. If you've ever tried setting schedules on thermostats with only a few buttons on the face plate you can probably relate to how frustrating it can be. For this unit however, the web interface through Honeywell Total Connect makes it quick and easy to make schedule changes. The app for iOS works well for this also though I prefer the regular web interface. Reliability: Once the unit was connected and happy, which took a little bit of work (see below), to date I have had no disconnects or some of the other issues reported by some reviewers. Wiring Setup: This took some head scratching but it in the end wasn't too bad. Upon removing my old thermostat, of course I found I had no "C" wire, and the labels on the old thermostat did not match the Wifi thermostat (the old thermostat had "G", "W", and and "RH/RC" wire, with only "G" matching). However I found that the instructions that came with the Wifi unit had decent enough cross-correlation for what to do with non-matching labels ("RH" was actually "R" for example). To deal with the missing "C" wire I was lucky to find a number of unused wires in the wire bundle running to the furnace with the existing wires -- I chose one and it became the "C" wire, hooking up to the Wifi thermostat on one end and my furnace (a York Diamond 90) on the other. Wifi Setup: This was surprisingly more painful then the physical installation, but once finally connected I had no issues. I had repeated "Connection Failure", error code "E02" which according to the manual means I was entering an incorrect Wifi network password -- but I was not. Through a lot of internet searching I found out my problem was I had a space in my Wifi network (SSID) name, which the Wifi thermostat does not tolerate. Removing the space from my network name solved the problem, however only after also changing my network security from "WPA TKIP PSK" to "WPA2 AES PSK" (the former is supposed to work however it would not work for me, at least with my particular router-Wifi thermostat combo -- oh well it was time to start using the better wifi security setting anyway!) Switching Wifi Networks: I replaced my old router with a new router recently (with a new Wifi network name) and tried to go through the network setup again. Not sure how to have it join the new network, I tried resetting the unit by removing the face plate from the wall, waiting a few minutes, and putting back in place -- well this only resulted in having to set the clock again and it was still looking for the old Wifi network. Tried this a few times with no luck. If I had read the instructions again I would have seen there is a section called "Disconnecting Wifi" with a particular set of key presses to have it forget the previous network and start the Wifi search again (hold down up and fan keys for three seconds, then change setting #39 to "0"). Did this and quickly had it on the new Wifi network. This is good to know how to do as I imagine you would need to do this if you changed your Wifi network password as well. The documentation is good, especially regarding installation and the wire hookups. They could add more Wifi troubleshooting hints -- it was frustrating when it was giving me an error suggesting an incorrect Wifi password when that wasn't the trouble at all. If I experience any major issues I will revisit this review but so far I am happy.

Me ayuda a ahorrar energía porque puedo programar toda la semana el cambio de ajuste de temperatura o apagado del equipo y así, si se me olvida apagarlo lo hago a distancia y si mi rutina permanece el equipo arranca cuando lo necesito y se apaga cuando no estoy.

This (RTH6580WF ) is a simple yet functional wifi thermostat. . The display is large enough to read. and a decent backlight. More buttons than you need and a decent layout. It just works. The install was straight forward (turns out I had a c-wire and didn't need the adapter). The basic settings worked out of the box for our hvac. The wifi function was very easy to setup - I even had to go back and connect it to a different network, which was also very friendly and easy to do. The "advanced" thermostat settings are easy to access and alter (these can only be done via the physical device, not remotely). I prefer programming the temperature settings via the Total Comfort web interface or phone application, but also totally straight forward to do on the thermostat itself. Total Comfort is basic and works well. Ecobee offers a more graphical representation of the settings as well as yearly historical usage, which to me allows for a better feel for how my house is set compared to TC's. I do think TC is easier to use than Ecobee's it's just a no frills bit of software that ..gets the job done well.

Not easy to use also the application not work in UAE
