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

Bought this because we currently have a Honeywell Pro T5 that is not wifi connected and schedules are extremely complex on the small screen and also convenience and ability to turn on before coming home.This was the easiest solution literally plug and play with the existing base plate pull off old one and plug this one in and initial setup can be done within 15 minutes.Make sure to download the resideo app and connects effortlessly now we have a wifi connected AC.We have the white framed model in my included pictures if you have this same one it will be plug and play.

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.

Very easy to install and connect with our wi-fi. It's very accurate in controlling the temperature. Great product for the money you pay.

I had a T4 Pro dumb programmable thermostat, but needed to connect it to my SmartThings. This was an inexpensive upgrade. It plugged right into the receptacle of the old one. I like that you can see the temp even in the dark without touching the screen.The only issue is connectivity. While it connected to Wifi just fine, getting it connected to SmartThings requires picking the right Honeywell application. There are at least 3 of them. "Residio" is the one to use to integrate it into SmartThings. However, if you add your thermostat to any other ones, it won't add it to that one. Keep that in mind. Also, if the hvac doesn't fire because the temp is below threshold, it won't report the current temp to the app. You need to refresh it. Other than these quirks it's an awesome upgrade. Don't sweat Home vs. HomePro difference, it's just a AA battery backup.

Honeywell can go suck start a shotgun.I'll admit, the first step was on me. In the 600 character title, I didn't catch the "C wire required" at the end. Nonetheless, a green (fan controller) wire will work as well. But, holy hell this is the worst experience I've ever had with a thermostat.The setup process is beyond complicated, and that's coming from a guy who works in IT. "Download the app" - okay, which app? There's several that it says. I think in the manual it says you need the Lyric app. Well, the Lyric app doesn't exist. There's honeywell apps, and I downloaded 4 Honeywell apps before I learned it's a RESIDEO app that I needed, of which there's THREE of those apps as well. Once I was able to find the right app, it started guiding me through the process - but it only took about 2 minutes for it to fail on setup. Plug it into the wall, select App Setup, make sure it says bLE at the top. Done. Your phone should start looking for the thermostat...... but it can't find it. "Hold it closer!" - it's 2 inches away from the thermostat.As it turns out, you need to select "NO" on the bLE. It'll then tell you to set your phone to airplane mode, turn on wifi, and find your thermostat's wifi - connect to that, set it up, and then you'll start being on your way. Everything checks out until it comes time for your thermostat to join the wifi. That's when it'll fail again. It does require to be on a 2.4Ghz band, which I've already got a split network set up in my place for that. Still, it refuses to join - it'll begin trying to connect to the wifi, and it will boot my device of the thermostat's wifi. The *APP* will then ask for me to connect to the thermostat's wifi again, in which it'll refuse to let my device connect back to it.After trying the process over and over and over, I gave up and tried setting it up without the app. From here, it managed to nearly get onto the WiFi... I mean, it did - my wifi notified me that a new device had joined my network. However, now the thermostat was telling me I needed to register it in order for the remote access to work.Fine. Whatever. I go online to see how I'm supposed to register it, and... well, you can't. For the T5, you need to register it through the app. The app that doesn't work. The app that fails on setup.This thing is almost entirely backwards in it's setup process. Everything will fight you every step of the way. This thing is far from "user friendly" or intuitive. Get something else. Get an Ecobee. Get a Nest. Teach your infant child on how to adjust your current thermostat. Anything is better than this.
