abunda_amazon_reviews 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.;;Reviewed in the United States on April 2, 2019;;1.0 out of 5 stars;;Not what was promised;;Jodi;;;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.;;Reviewed in the United States on April 4, 2019;;1.0 out of 5 stars;;Do NOT buy this thermostat;;P. Healy;;;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.

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.

Easy to install hardware; horrible integration with wifi
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.
