    Traded my Honeywell TH9320WF5003 WiFi 9000 (which worked flawlessly for many years)for this thermostat because of the remote sensor function. Due to the placement of the thermostat in my house, which is too close to the A/C diffuser, I always wanted to have it moved.
    This thermostat seemed to be the answer, as I could put the sensor in the part of the house that I wanted to regulate the temperature.
    Installation was easy. Then I downloaded the app. An absolute terrible piece of software.
    The app that controlled my previous thermostat was made exclusively for that purpose. This new Honeywell home app seems to work with all their devices, unfortunately when you try to get vastly different devices to work with the same app, functionality suffers.
    In a nutshell:
    1-Constant WIFI dropouts
    2-Inability to tell which sensor is currently selected.
    3-When you go into the prioritize screen, the schedule is shut off and thermostat goes into hold mode.
    4-Incorrect temperature showing. Unless my bedroom is always 72 degrees and my living room is always 74.
    5-Inability to change the brightness of the display. You can practically read a book by the light this thing emits.
    6-Lack of info on the display. Its a very large display that shows only one thing. The current temperature. My old thermostat (which was smaller) showed Current temp and humidity, Temp that the device was set to, up and down arrows for adjusting temp, Outside temp & humidity , Current time and date. Here''s the link: https://www.amazon.com/review/create-review/ref=cm_cr_dp_d_wr_but_btm?ie=UTF8&channel=glance-detail&asin=B07N849J21

    Im in the process of returning mine. I''m hooking the old one back up.

    The concept for this thermostat (T-stat) is great. The software execution is abysmal.
    The temp readings for the app and the T-stat never agree. There is always a large, unexplained difference.
    The T-stat NEVER appears as an active room in the app, even though you wave your hands endlessly over the T-stat. Only sometimes does the t-stat appear as an active room on the t-stat.
    Result of all this, is the system delivers completely erroneous temp data and is essentially worthless.
    I’ve called Honeywell twice to question this. CS people are very nice and try to be helpful, but know nothing. So, my questions are never answered.
    I believe there is a material defect in the software, and I believe the t- stat hardware is unable to recognize room presence, thus making everything useless.
    Sorry, Honeywell, I’ve owned 4 different versions of your t-stats. The T9 is worthless.
    DO NOT let “Vine” reviews ( people who receive the product for free) sway your opinion. Give someone a $200 product for free, and it will shape their opinion.

    I shopped my smart thermostat for a long time and came to a few conclusions:

    1. All the so-called "AI" features on Google Nest and other smart thermostats are just a gimmick. The reviews on those products prove this, you can find an endless stream of comments saying it "learns" to do the wrong thing over time. One need only watch the 1984 classic "The Terminator" to know why we can''t trust the robots with control over our most precious technology. These features are supposed to make your life easier by not having to set a schedule. I found the schedule feature to be incredibly simple and intuitive on this Honeywell device. I included a picture of the interface. I programmed it in about 3 minutes from my phone.

    2. The other smart thermostats are not pleasing to the eye. They may look good on modern homes but in a somewhat plain or modest home they stand out and not in a good way. I needed a simple white thermostat with an easy to read display for anyone at any height level. The Honeywell is simple and uses all the device space as one huge screen. It''s like the Tesla of thermostats in terms of screen size and display information at a glance.

    3. This thermostat is able to be locked down such as in a rental or AirBNB. Meaning the settings can''t be modified other than adjusting the temperature up and down. This is basically a simple mode for the whole family or for your renters. They need to be able to adjust the temperature but they don''t need anything more than that. It''s great for family uses but if you''re a professional property manager there is an upgraded version that can be operated in bulk. I like to just buy the best on the market so I shopped that option and decided that I don''t need those features so this is the best on the market for residential use.

    4. I used an installation service with OnTech. I learned about them from getting my Ring Doorbell installed with them. They gladly installed this device too and it works really well. They said the installation was very standard and nothing special on my particular house and hardware. I would really suggest doing this installation if they service your area. It was cheaper than hiring a professional electrician and the workers they sent were more professional and knowledgeable on smart home installations than a typical electrician.

    5. The app is really easy to use. I set up an account then logged in wife''s phone with the same account and we can both manage the temp. We don''t have to because the schedule works great but sometimes it''s nice to adjust it from the couch without having to get up.

    6. It''s all about sensors. Sensors sensors sensors sensors. Did I mention sensors? None of the other smart thermostats have room sensors. Their supposed smart features just learn from your personal behavior not from any real world information. So if your family gets up and adjusts the thermostat randomly one day it learns that behavior. Very useless behavior. This actually reports real time temperature and activity information from your room sensors and adjusts the heat and air conditioning based on that data. For example you can set the priority to "active rooms" and it will prioritize rooms that show activity. Or you can use GPS settings to prioritize when you''re home and not head the house when you''re away. Lots more actual smart features on this device than the competition. These features are not gimmicks they are real features you can rely on.

    I wrote this review because I spent a lot of time researching and thinking about the options. I hope it helps a few people make the decision. Please hit the "helpful" button for the next person that is walking this path and might need a little help.

    I replaced one of our Honeywell 9850 thermostats to gain access to two different rooms (Master Bedroom; Great Room). Easy installation of hardware, and sync with remote room sensor. From there on, all downhill. Works on a separate application from other Honeywell Thermostats. So stuck with two apps (one for upstairs, one for downstairs.). App loaded, but could not sync with thermostat. Honeywell claims it works with 5ghz - not so if you search the internet. Fired up old router with 2.4 ghz, and finally got the app sync''d. (that took 2 days; sent Honeywell an email, nothing than and automated response "we will get back to you in 24 hours) never reply. Called support, and they told me it should work and the problem must be mine.

    Finally got it working. Interface on application and thermostat is very poor. Frustrated both my wife and I. So - I took it out, reinstalled the 9850 and all is working again. This product is far worse than Nest or Ecobee.

    I''ve had the nest (gen1) for several years and have generally enjoyed it until a power outtage appears to have burned out the wifi on it. After calling the Nest support, they indicated that was a problem with Nest and they were susceptible to power outtages (at least the first gen). Given such a basic flaw in the nest design I decided to look for a different thermostat.

    For some time I had considered the Ecobee but had heard that while the sensors were great other areas just weren''t as user friendly. When I saw the Honeywell T9 thermostat that seemed to have everything I could want feature wise, and previous generations were generally very well thought of despite the lack of features in the earlier generations compared to the nest and Ecobee. Given the rave reviews of previous generations of Honeywell thermostats and the newly added features I decided to pick up the T9.

    While the Honeywell thermostat is new and I can''t tell you about the long term features (ie durability, AI, etc...) I can give you some information on the setup process...

    Physical Installation:
    This is the part that may catch the most flak from customers coming from Nest. The requirement for the "C-wire" could cause you have to install their adapter in your Air Conditioner Unit. While this isn''t actually a horribly complicated process, people who are skittish of wiring and electronics are likely to be displeased by the need for this adapter if they don''t already have a "C-wire". In my case I was in the middle of installing the adapter when I found that my "C-wire" simply wasn''t used, I was able to simply connect my "C-wire" up without needing the adapter and I could now wire it up normally. But really, as long as you can follow some basic instructions setting up the adapter is not as scary as it may seem.

    Other than the requirement for the "C-wire" the physical installation is essentially the same as setting up a Nest thermostat. Simply plug the wires into the correct ports on the wall bracket and that''s really it.

    Once physically connected, turn the power on and the thermostat will come up and start walking you through the setup process including joining the thermostat to the wifi and adding sensors (sensors are added through the thermostat not the app). The touchscreen was very responsive and worked great. I had zero problems with the installation once I worked out my missing "C-wire" issue.

    App Installation:
    - App installation was simple (though it does require creating an account (as does the nest)).
    - Pairing with the thermostat was very simple and you were automatically walked through this process.
    - Setting a schedule was extremely simple (much better than the nest), allowing you to simply set home, away, and sleep settings instead of having to schedule daily settings (though this is still an option if you want it).
    - Once everything is setup you can pair your sensors with your settings so it knows which sensors to prioritize for temperature control. For example my sleep setting is paired with my master bedroom sensor, while my home settings are paired with my office, hall, and living room sensors, and my away settings are paired with all sensors.

    So far I would highly recommend the Honeywell T9 Thermostat. The physical installation was as easy as any other thermostat with the exception of maybe having to install the "C-wire" adapter (a one time thing, which you really can do yourself). The software was even easier than the nest to setup and use, and the sensors all appear to be working as expected. So far the Honeywell T9 has delivered on all of its promises and is the best smart thermostat I have used to date. 5/5

    If I were to make any recommendations for the manufacturer they would be as follows...
    - remove the requirement for the "C-wire", this is not required by nest and installing the adapter may be more than some people are willing to tackle even though it is really something that can be self-installed.
    - add the option to add sensors via the app instead of requiring that they be added through the thermostat. This is a minor gripe, but there is no reason this functionality couldn''t be added to the application for ease of use.

    (this review is long but detailed - hope it helps someone)

    I hesitate to review this thermostat too soon, as I bought a Honeywell RTH9585WF1004 ($200) 14 months ago, gave it a good review, then 13 months later it completely lost any accuracy of the actual temperature - and why I now have the T9. I also hesitated to continue with Honeywell, as the past 2 wi-fi thermostats from Honeywell were horrible (TH9320WF, returned within one month, and the RTH9585, worked for 13 months) - but I didn''t like the other brands available. The T9 is brand new, and the remote sensors sounded awesome for my house - 2 story, 1 AC unit, terrible air circulation, temp varies between floors/rooms.

    INSTALL: I removed the inaccurate Honeywell RTH9585, and installed the T9 according to the very basic install instructions. I had one issue with installation which was my own fault - set the wrong type of HVAC unit in Setup, so the AC wouldn''t turn on - then I caught my mistake. I''m still not entirely sure I have the correct type selected, as the T9 indicates my heat pump is 2-stage and I don''t believe it is...I''ll find out in Nov when I need heat in Arizona.

    SMART ROOM SENSORS: Bought a total of 4 Smart Room Sensors, 2 for upstairs (one in M Bed) and 2 for down. After installing the Base unit, went to Settings and simply followed the unit''s displayed procedure for installing/naming the Smart Room Sensors (place one sensor, return to the Base, name it, then go on to the next sensor).

    SCHEDULING: This section was really easy setting up a "5+2" day schedule which allows for multiple Away/Stay cycles (vs the usual 2 On/Off, On/Off cycles on previous thermostats). It was also really easy choosing which Sensors to use in the programming. Example: WAKE time, I''m in the Loft on the computer, so that''s the Sensor that the Temperature is based on. AWAY time is mid afternoon (Peak Pricing) so the temp is set higher. HOME is at evening (when Peak Pricing ends), I''m always downstairs in the Kitchen or Family Room, so the Temperature is based on those 2 Sensors, SLEEP at night the Temperature is based on the Sensor in the M Bed. More cycles can be added - I''m not sure if they can be named differently. I have the sensors set for times, but they can be used as motion detectors to detect Activity, making them active. If multiple sensors (that you selected) detect activity, the temperature is based on the average of the Active sensors. I don''t know what happens if a sensor senses brief activity (like grabbing something from the kitchen then leaving that room, example) or what happens once one goes to bed, thus there is NO activity. For me, using set times is better. Geofencing is also an option but not one I need/use. It detects (via your cellphone) when you''re in/out of range and adjusts the temp based on that. (how it works with a family, I don''t know) I''m honestly not gone for more than several hours at a time, plus I have a zoo so can''t let the house get too warm/cold.

    HONEYWELL HOME APP (Android): After a week using the Schedule I''d set, it needed a bit of tweaking with some temp changes and changes in renaming/moving a Sensor. I had already installed the Honeywell Home App on my phone but hadn''t really messed with it - so I did my "tweaking" of the T9 programming through the App, not the Base unit. It was a bit confusing at first (it''s not super intuitive) but, once I got the layout of the App, I was able to make temp changes, move a Sensor, rename a Sensor, adjust some minor details. Using the App (once I got the hang of it) was easier to program the T9 than using the Base unit - I was able to do it sitting down in another room vs standing, hunched over at the Base unit. The App can''t be used for the Initial Setup of the Base unit, obviously.

    CONS: 1) Wi-Fi is supposed to be 2.4Gh or 5Gh. I tried to set the Base to my 5Gh signal...it found the signal but would not connect to it - I got an error message and told to contact Honeywell Support. I didn''t want to mess with that (I''ve read it needs a Firmware update - I just haven''t checked if that''s true) so it''s set to the 2.4Gh signal. Honestly, don''t know what diff it makes, why would a thermostat need a faster signal? Only reason I can think of is that my phone is set to the 5Gh and the T9 to 2.4Gh - BUT I was still able to reprogram the Base using the App, so I don''t know.
    2) The instruction manual is very basic; it gives very brief install instructions, the pictures of the wiring could be a little bigger/clearer. There are no instructions for installing/setting up the Sensors (the Sensor box has a very brief install/program/pairing instruction). That''s all described (fairly well) on the Base units display.
    3) The Honeywell site has no more instructions than what''s in the box. There are some VERY short (~2min) videos on how-to for a few basic things but I didn''t watch them. An Online User/Help Forum would be a great addition, I''m sure most people have the same basic questions and some need more detailed instructions - forums are super helpful. It''s possible they do have a Forum somewhere but I didn''t see one or a link.
    4) Alexa is supposed to work with the T9...and it does (once you add the Skill through Alexa - make sure to remove the app/skill for older thermostats) but it''s rather confusing. The Alexa App did a search for new items and it found the T9 Base, as well as the 4 Sensors. I can use really basic commands BUT you have to use the name you gave to the Base and/or Sensors...I said, "Alexa, raise the temperature 1 degree" and it replied, "I found multiple items...". I haven''t explored it enough to know whether I can say, "Raise the temperature of Kitchen 1 degree" or so on for the other Sensors - and again, Honeywell has NO online instructions for using Alexa or other voice apps. On the other hand, for now I have the programming/scheduling JUST right for all rooms and various times of day, so I''ve not needed to change it since my tweak.
    5) The price is a bit high. Over $300 for the T9 and 4 Sensors (especially since I spent $200 last year for the previous Honeywell unit). So far, having the house a LOT more comfortable and NOT having to be changing the thermostat setting throughout the day, it seems to be worth the money.
    6) The sensors are applied using double-sided tape. This is both a pro and a con. Even after cleaning the wall where one sensor was going, the sensor fell off the wall 5'' to the tile floor. The tape is nice for not having to use screws and in that I decided to move one of the sensors, but I''d feel better using a screw.

    PROS: 1) It''s only been 2 weeks, but the T9 is working great and it''s nice having various rooms of the house at slightly different temps at different times.
    2) Easy installation. For my HVAC unit (12 yo heat pump) the wiring was simple enough and I already have the C-wire. The T9 does come with an adapter for homes without a C-wire, I don''t know how easy it is to use.
    3) The Setup was actually very easy to use (aside from the 5Gh Wi-Fi not working).
    4) The Honeywell Home App is also easy to use, once one understands the interface.
    5) Multiple Home/Away cycles. I''m generally home all day so I don''t need more than the usual 2 On/Off, On/Off cycles but I''m sure the additional cycles are convenient for some households.

    Final thoughts: I''ve read several other reviews complaining of needed firmware update and a hassle of needing to use 2 Wi-Fi phones to do the update. I couldn''t get the 5Gh to function, but the 2.4Gh works just fine. I guess some people have their Wi-Fi set up so there aren''t 2 separate signals? I''m not sure - but I might find out someday if I ever decide I really want the 5Gh signal. I''ve also read people complaining about the App not working. I''ve had no issue at all with the app. Also, I''ve seen people state that if the power goes out, the entire T9 configuration and schedule is lost. I haven''t had power issues, I just hope that''s not the case. One would think that the settings are saved either at Honeywell Cloud or on the phone, if not the unit itself (though it doesn''t use batteries). I hated the previous Honeywell Wi-Fi thermostat, but it never lost it''s programming so I can''t comment. In my experience so far, even though the included instructions were very basic, the setup for the T9 was straightforward and easy to comprehend using the Base unit''s displayed instructions. I only hope that I didn''t spend $300+ on a Honeywell Thermostat that will only last 13 months, as my last $200 unit did. So far, I love it.

    I like this thermostat. The thermostat for the sleeping side of the home is in a hallway. When bedroom doors are closed, there is inadequate airflow to give temperature feedback to the thermostat, leading to long AC cycles and inconsistent bedroom temperature fluxuations. The T9 nicely solves the problem by letting us have a remote thermostat in one of the bedrooms to take over control and transmit the room situation to the main thermostat. It works quite well.

    I am above average around home systems, so if you plan to install yourself, know this: In order to have full control of the HVAC system, the thermostat needs to have access to the "C" (Common) connection on the indoor furnace or air handler. In my case, the connection was not available at the wall thermostat location. This is because the mechanical thermostat the T9 replaced did not need access to the "C" connection. Lucky for me, the installer many years ago had used standard thermostat wiring. This wiring has the blue "C" wire. In my case, it was simple to connect the blue wire to the "C" terminal on the furnace, then connect the other end to the thermostat. Bingo. Worked instantly.

    My wife objected to how bright the display is, but I simply went into the menu and reduce the brightness to the level you see in the photos. There is peace in the family!

    I replaced an older Honeywell thermostat because I wanted the ability to add sensors around my home. Installing the hardware was easy as the wires matched the old one. Next it was time to configure the T9 to the home app and that''s where the problems started. I spent over 4 hours chatting with 2 different agents and a phone call. After 4 hours the T9 still would not register. It took creating a hotspot on a phone, connecting another phone and the T9 to it. I only had 1 phone at my house so I had to wait for a few days to get another phone for this to all work.

    Adding a thermostat should not be this complicated. If a customer has an issue then support should have the ability to add the T9 on the back end. It also does not help when support asks you to try troubleshooting features that the T9 does not offer. Another issue was the phone number listed for support took me to a recording that they were closed on the weekends. Chat support had to provide me with a different number after they verified the closed recordings.

    Multiple issues: Returned Inaccurate and Too Bright
    Reviewed in Canada on October 5, 2020
    3 issues and returned as a result 1. Temperature reading was not accurate, could range and be as much of 1c or 3f off. This was not consistent so could not use the advanced preferences which allows for an offset. But since not consistent would not work. This was confirmed...See more
    3 issues and returned as a result 1. Temperature reading was not accurate, could range and be as much of 1c or 3f off. This was not consistent so could not use the advanced preferences which allows for an offset. But since not consistent would not work. This was confirmed with an independent reader and older Honeywell thermostat. 2. Screen when active is way too bright and not adjustable. Idle and sleep screen can be adjusted but unless complete off it is too bright to have in a bedroom. Then the biggest issue is when you touch the screen to check the setting the screen goes to 100% brightness. This is not adjustable and essentially you can land a plane in your bedroom it’s so bright and wakes everyone up. Simple fix would be to allow for the active screen brightness to be adjustable. But it is not 3. Alexa integration with app. If you have all setting to C no matter what when asking for the current temp of the room it returns in F. So when setting it causes C and F confusion. Lack of app support.

    The unit worked only for 11 month, then just died (short on 24 VAC circuit) and took furnace''s board with it. Had to replace furnace board. It was scorching hot outside, so had no time to fiddle with warranty - needed AC running to survive at home, so wend to Home Depot and just piked-up another thermostat unit (same model). Guess what? HVAC guy spent 3 hours installing it (all wires were already in place!) - the unit turned out to be just defective, won''t turn AC or Heat at all - only fan control was working. Tried to call support line - they work only regular business hours (Yeah, right! Why would people need AC on weekends?) Survived a night and next morning replaced the faulty unit with another new one - it finally worked. Let''s wait another 11 months, but no way I will be replacing it with anything made by Honeywell. Overall impression - do not put your home comfort in hands of Honeywell - they will fail you.
