Honeywell Home RTH6580WF Wi-Fi 7-Day Programmable Thermostat, White

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.

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!

Physically installing it was cake! I was lucky enough that my previous thermostat (pictured) was also a Honeywell that happened to use the same base (th5220d1003), so I didn't have to do any wiring. Setting up the wifi was much more involved. On the day it was scheduled to arrive I changed the name of my wifi to something shorter because another reviewer mentioned that this can be an issue. I then spent the rest of the morning resetting all my devices (including some plugs and switches) over to that. Totally on me. I made that choice. When the thermostat arrived and had been installed is when it all went sideways. I couldn't make the thermostat connect to the wifi. Honeywell tech support had me follow the directions I'd been following for an hour two more times and after a half hour told me I needed to connect on a 2.4 GHz service. I knew I had dual service (and remembered that with a previous provider I had two named wifi connections) but couldn't remember much more than that. So, I called my internet provider who set me up with two distinct connections. (This didn't cost anything as it was already a part of my service.) This did mean the wifi name changed again, though. So, while getting the thermostat to connect to wifi went well, I also had to reconnect all my other devices for the second time that day. Alexa integration was easy from there. I've set up a simple schedule for temperature control. I can remotely control the temperature with Alexa but not set the system from AC to heat or turn it on and off. That has to be done manually or with the Total Connect Comfort app that Honeywell recommends. (The app has some preset schedule that you'll want to delete if using Alexa primarily. I actually didn't notice this for weeks! I thought my husband was messing with the temperature.) The truth is, the setup really ruined my day. I was frustrated and snappy. Not at all the person I like to be. But I'll get years of use out of this thermostat that will, hopefully, save me money. It feels like an ok trade-off. ****One year later and I'm still happy! I don't have (or notice?) any cycling issues and the system seems to turn itself on and off at normal intervals. I love using a timer and voice commands but my favorite things have been turning the ac back on after a week's vacation when we're still an hour from the house or deciding it's finally cold enough to turn the heat on while still laying in bed. 8/23 - This disconnected from WiFi when I was installing some blink cameras. As I was trying, without much success, to reconnect it, the heat came on and I was never get it to work properly again. I had my old thermostat in a drawer so I just plugged it back in with no issues. I'm disappointed but ultimately not unhappy with the purchase. I'm not sure my energy savings quite paid for it, but between the savings and "value of use" it was well worth it. I'm upgrading to a newer smart thermostat.

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.

Easy to install & now I can control my thermostat wherever I am as long as I have WiFi!

I purchased 4 of these units for our property which houses our studio and main home, sometimes rented as a vacation rental when we are away. Installation and WiFi connection was reasonably simple, We were so overjoyed that we could monitor and control our heating/cooling systems form our iPhones and computers. All seemed well, until one heat pump stopped heating, but said it was with the fan running. Swapped the thermostat with one of the other working units and the problems switched to the other HP. Simple enough, just a bad thermostat, one unfortunately that went bad in just 3 months, but sometimes these things happen. The BIG problem was in getting the warranty covered with a replacement unit. Even though the unit worked perfectly after swapping out the thermostats, and the fact the the original bad thermostat had been operating fine for 3 months, the Honeywell "authorizing" technician (India I believe outsourced connection) forced me to go through 2 hours of tedious and redundant troubleshooting before authorizing a replacement. He said he was a well trained tech, but truth is, he didn't know basic troubleshooting logic, he was reading strictly from a script wasting a lot of my time. I happen to be a technician with lots of experience in heating and cooling systems, amongst other things, including IT. After hours of frustration, he eventually agreed with my assessment and a new or refurbished unit was promptly mailed to me. Only a few weeks later another of the units logic circuitry has failed, turning on the air conditioning compressor along with the gas furnace. Swapped units out again to discover the logic circuitry failing again. I dread calling in for a replacement and having to waste another afternoon with some "technician" reading strictly from a script, which I suppose they have to do for many homeowners. I understand this, but the lack of technical knowledge and need to do tests that are obviously unnecessary makes the replacement policy tedious and frustrating to say the least. These units works great when they do, but 2 failures out of 4 in 4 months does not bode well with hardware reliability. If a 3rd fails soon, I'll be switching out the units with another brand and selling the new replacements they send me. Update 2/1/18: The third unit has failed in less then 2 years, making this 3 out of the original purchase of 4. This time, the thermostat ran the compressor and it's exhaust fan (but not the interior fan) continuously while we were away on a month vacation. When checking the thermostats from abroad, the unit said it was off, including the interior fan. However, the compressor and it's exhaust fan were running he entire time according to our neighbor. After arriving home and trouble-shooting, If I turned the power to the unit off, it would recycle and run normally for a little while, than without any input, it would turn the compressor and exhaust fan on. I checked all initial programming parameters and they were correct. In swapping out one of the good working units to see whether it was the the heat pump or the thermostat as the problem, it corrected the situation. Unfortunately, it's outside of the warranty period. Since I had 3 Honeywell units working and didn't want to change out the entire system (I just wanted to keep one app on my phone to control all 4), I ordered a new one and installed it and the problem is gone and everything is working as it should........until the next break-down. Honeywell needs to make their units more reliable in my opinion. Too bad, it's a nice unit otherwise. If you can get an extended warranty, purchase it when ordering one of these. Not looking forward to next months electric bill.

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.

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.

Easy to install and easy to setup. Wi-Fi is a little tricky but still fairly easy to setup, using a laptop made it much easier to setup and register. The app and computer software works well. Thermostat works as expected. So far so good. Good price for a decent thermostat.

De lujo, de excelente calidad y el App está muy bien!!!
