RTH8800WF2022, T5 WiFi Smart Thermostat, 7 Day-Programmable Touchscreen, Alexa Ready, Geofencing Technology, Energy Star, C-Wire Required

Great thermostat- been using it for over a month and it works as intended. Very easy to set up, there is a lot of support videos on youtube if you are not handy. You might need a universal bracket to adapt to your wall hole but that is cheap and easy to find in amazon. Best of all? Not getting 150 thousand useless notifications from the app. Simple, to the point with smart functionality

I live in an apartment which has the cheapest Honeywell T4 non smart/ wifi thermostats installed in the units. I wanted to use Alexa to control my room temp so I bought this for a perfect upgrade. It took less than 10 seconds to install. I just pulled off my old one and pushed in this new T5 and done. Easy 5 minutes to run through the wifi and app setup process and everything worked like a charm. My apartment had the exact same 5 wire pin out on the back so I didn't need to change that, I didn't need to open up the bag of screws or anything. A monkey could have done this upgrade. The touch screen looks really really nice, I can read the clear temp numbers from across my large living room. The app is easy to use and the touch screen is just as simple and easy to figure out. If you are doing an upgrade like myself but your current thermostat wiring is missing the 5th "common" wire, then this model won't work. You would need to get the Z model T6 that comes with batteries for the backup power. They will provide the common wire power. Hope this helps you out.

What can I say, it is a thermostat and it looks nice, I bought it for these reasons. I bought it in April of 2023 right after I had a leak repaired and the old thermostat looked very dated in a freshly painted room. It installed very easily and It really does look nice and new in the room. Once up I was pretty happy with it. I set a schedule and that's where the enjoyment stopped. As time went on I began to wonder if I had a leak or something, I had one in the past after all. It would not cool, and the temperature in the house would rise. I'd set it to 71 but the temp would slide degree by degree to 77 (which is what it was scheduled to hit at 11pm) and stay there for the night. Suddenly waking up freezing in the morning. The pillows in the bedroom were muggy and damp intermittently. Some days we'd sit at 77 degrees for no reason. The heat pump is running near 24/7 trying to cool the house.... Luckily I am pretty DIY and troubleshooting for hobby so I bought gauges to monitor my unit and learned what Superheat and subcooling are. I determined that I don't have a leak! So what is it? I have an energy saver cycling box from the power company, I have that taken off, it takes a few weeks for them to do it. but my problem persists! I'm going mad, inject dye to search for leaks? I change filters, etc etc. anything i can. I'm debating draining the unit, perhaps the repair guy put in too much or incompatible oil! I begin to suspect the thermostat, all the internet says it couldn't be the thermostat, no no It could never.. But I say I say you know what let's reset the thing and strip away features. So I did, Reset it, turned off scheduling, wifi, and anything else "smart", got into the special menu and found "adaptive recovery" looked it up and determined this and scheduling were my problems! Because I wanted 72 from 8am to 5pm but the 77 at 11pm. The stupid "smart" algorithm thought that meant I want to be 72 in 8am and for the rest of the day slowly drift to 77 by 11pm and then freeze us half to death at 5am to be 72 again by 8am. If I set my schedule to all 72 degrees it will never leave 72 even on a "hold". I assume because of crap programming that adaptive recovery does not take into account the "hold" or manual input/changes which is bullcrap. I decided to see how badly programmed this algorithm was. I put a schedule on with crazy temperatures like 50F at 8am and 90f at 5am or something. The stupid thing would actually turn the HEAT ON to after 8am so that it be 90F by 11pm even though the cool setting was set to be 50F at that time. what a dumb program. Heating when it should be cooling! I was smart enough to figure this out and disable these features, I won't even use the schedule now Im too afraid too Which is same because I really wanted to let the AC drift off temp at night but its not worth it to trigger the "smart" alogrhtium's stupidity which seems to have the ability to override your manual temperature settings even without being turned on. I see no where to fully disable this "smart" features. I feel bad for anyone that calls HVAC specialists to try to fix these issues and they get talked into the a whole new system because of some programmers' poor programming skills.

I would save your money on the new ones and just buy the refurbished models in these that they sell on Amazon. They would likely work just as well. I got the new ones for 75 on prime day. The refurbished ones sell for 60 all the time. They work for the most part. Setup is fairly simple. GeoFencing seems to break functionality for me, so I turned it off and just use alexa and the app to tell it to change temps when I leave the house. The screen is nice and I like that you can adjust the brightness from you phone. I don't like that it goes down to just the temp reading in the house which is the sleep mode. I would prefer it just leave all the information up all the time so I can read it when I walk by without having to touch it. Make sure you know exactly what kind of heating unit you have. I just bought a new build and they told me I had electric heat without a heat pump. They told me wrong, and I do have heat pumps. If you put the heating and cooling information in the wrong during the app set up it will not call for the correct air. Make sure you double check this before installing, as I learned the hard way, and had to reset the thermostats and start all over I can't speak on wiring it up as I didn't need to that since I had the Honey Well pro series thermostats(Non-WiFi) in my house from the build. It was a plug and play method for me, which is why I bought these. Saved me a lot of time. Over all I like them, but I do feel like they take forever to register that the room is actually to temp and causes my AC to run a little longer. I'll see how my electric bill compares to the month before without these installed and update my review. Also wish they didn't go into sleep mode and instead showed all the information on the screen all the time. Also wish the GeoFencing feature worked better, but this could be more of an issue with my phone not registering in the area correctly. As I said, take a chance on the the refurbished ones it will save you some money and probably work just as well.

Hardware is good. The ease of being able to update from a previous generation without having to muck about with wiring is the high point of this product. You can pop the old one off the wall and put the new one in. That's smart! If only light switches and receptacles were made the same way. However, if you are buying this its probably because want to really make it work for you (automate), and that's unfortunate because you have to deal with their software and their software is terrible. I have never been able to get this onto my network because the initial "sync" failed and now its just in a hung state. Their support is useless and they seem more interested in wasting your time so you will go away, than actually helping you. They ask you for things they don't need to help you and don't understand what it is they're asking for. At no point when I was talking to them did they ask me "What seems to be the problem?" They told me that I needed to go reset my router because I wasn't using 192.168 as my IP range. And at that point, I was 2h into trying to get this thing online and gave up. As someone else said, go get a different product rather than waste your time with this one. If Honeywell were smart, they would invest their money in an open source SmartThings project where their developers would work alongside people who were smarter than them rather than keeping Residio alive and having to deal with cloud infrastructure costs. No one is going to pay for an app in order to run their thermostat so this Residio exercise is just a waste of time and money for them.

The box was a little beat up, but the product inside was fine. Works as it should after a little ChatGPT assistance on installation—super helpful resource, by the way! This unit works just as it should through wifi or the touch screen, and has all desired features, though a few options are deeply hidden in the installer-setup menu. I have a few others like it in businesses and rent houses and they all seem to be reliable units of good quality. They are fairly simple and don’t even confuse those who are less technically inclined. Overall, recommended…

I was looking to upgrade my original (non wifi) home thermostat with a wirless version. We bough the home new in 2019 and it only came with a Honeywell TH4110U2005 ProSeries thermostat. I knew I could replace the thermostat but didn't want to have to re-wire and affix a totally different wall plate/wiring plug onto our wall. I was hoping I could find another Honeywell version that might be a direct match for our particular wall plate/wiring setup. I am somewhat of a handyman and did not want to spend the money on using a professional to install a newer wifi version. So I did a little Amazon searching and finally found this Honeywell Home Intelligent T5 (wifi) version. It looked almost identical in the provided pictures. All measurements seemed to match up with what my tapemeasure told me as well. The advertisement did say this new thermostat required a "C wire" in its hook up. I had no clue what a "C wire" was. Apparently if your original wiring/plate doesn't include a C wire an additional wiring kit was needed to make it work. So, after I pulled the old thermostat off its mount, I could see how the wiring plate was configured. The mounting plate looked identical to what was shown in the advertisement for the new thermostat. I could also see a wire spot in the wiring/plate that said "C". There was in fact a wire going to the post labeled as C. Intuitively I was fairly confident that this new thermostat would be directly compatible with the old wiring/plate mount on our wall so I placed the order. After the item arrived I went to work and it took probably 30 minutes to unbox, read (somewhat) the instruction manual, pop the thermostat into the wall mount (it fit perfectly), download the device app, set it up with our home wifi, and then get the cooling/heating parameters all set up like we wanted them. The only thing I forgot to do was flip off the circuit breakers (like instructions said) to the HVAC before I popped out the old thermostat and inserted the new one. But I had shut off the HVAC system using the old thermostat before I pulled it out. Everything worked fine so I don't think anything got messed up as a result. We have since been using this new thermostat for about a week now and I am pleased with its performance, compatibility with the older thermostat setup, and reasonable price. The app on my phone allows me to control everything while I am away from home as well as a geofencing feature. The thermostat is doing everything that was advertised and I expected. I am happy with the purchase.

i don’t know why it says that this is a frequently returned item, this is a great thermostat. we wanted something fancy, but not too fancy. once you get too fancy, things get too complicated and don’t work as they should... but THIS! this is the perfect fancy, but not too fancy, still easy to use and not complicated - thermostat! i love that i can control it from my phone using the app and set schedules for “away” and “home” times throughout the day to essentially have it not running, etc. it’s a great little unit! it’s also pretty, i love the dark screen and the touch screen. definitely a great and affordable asset to be more energy efficient! install was pretty self explanatory, just follow the prompts and answer the questions in the set up menu on the device. i think you’ll like it!
