Honeywell T9 Smart Thermostat - Plastic - White is rated 3.5 out of 5 by 238.
Rated 5 out of 5 by from Reliable product Purchase the T9 w/1 remote sensor. Fairly easy to install on my 2010 Carrier HVAC which has the "C" wire. The instructions are simple enough but I do recommend reading it completely. Used my iphone with their APP which seems to work well and has not crashed or locked up. The remote sensor (2 AAA battery included) does exhibit long Hysteresis which I feel is good to prevent temperature flapping. It also has IR occupancy sensing that can be turned off. Been in use for about 10 days now, and so far its been reliable and works consistently. For those IT technicals, your WIFI AP must support peer to peer discovery otherwise the Smart phone app will not be able to discover it.

Rated 1 out of 5 by from Needs more work! I had the T9 w/ 1 sensor installed for 3 days. The AC would run for 6-10 minutes, turn off for 7-12 minutes and cycle like that over & over. I tried moving the sensor to different places and setting only the thermostat and/or/only sensor as the priority temp reading. The thermostat software algorithm that is supposed to learn needs a lot more work. This run rate will wear out the HVAC equipment a lot faster than my high end non wifi thermostat I just re-installed. My 5 year old high end thermostat that has compressor lock out and differential - cool swing - heat swing settings, runs the AC for 12 - 14 minutes and stays off for about 40 minutes. The house stays very comfortable and my equipment is not turning on/off 5 times more an hour.

Rated 2 out of 5 by from Lack instructions on how to set it up This T9 thermostat only comes with the Installation Guide. It does not come with operation and programming guide. The installation guide does not even mention I need to have an app on my mobile device or which app should I download. I need to call the help line to know I need the Honeywell Home app and all the programming steps are done with the app. Although this thermostat can run alone without the app, the clock on T9 will stop working if I have a power outage and make this thermostat useless. If I had T9 connected to the internet thru WiFi with installing the app, the clock will set to London in UK and I cannot change the time zone.

Rated 2 out of 5 by from I have 5 Honeywell WiFi thermostats. 4 use one app and this one uses a different one. That makes no sense to me. They all should be integrated. This one is far more difficult to operate and confusing! This thermostat tempvsetting aren’t accurate

Rated 2 out of 5 by from Display is terrible, unreadable, too bright The sensors, notifications, etc. are all nice but the display ruins the product completely. The font is TOO THIN. I'm tired of all these tech companies using these "modern" thin fonts. You can't read the thermostat unless you walk up close to it. And the white background?! Why?!! It's too bright! Even with the brightness turned down to 10%, it's an eye sore in a dark room. And again.. since its unreadable, it's just a white box. Completely pointless. I'll be downgrading back to my wifi color thermostat, which had a pleasant thick white font on a dark blue background. Even though the font was much smaller, it was thicker, and could be read from across the room.

Rated 1 out of 5 by from Main Thermostat works fine, but the remote sensor drops offline constantly. I tried new batteries in it and it is also only about 25 feet from the main thermostat. Very disappointed considering how much the T9 cost. Definitely would not recommend!
Date published: 2019-10-23
Rated 1 out of 5 by from Difficult to install, once installed temperature isn't accurate and changes arbitrarily, difficult to sync with app, app still has no control over thermostat, go to bed set on 76 (which is much colder than 76), wake the next morning to 70. Worst ever

Rated 1 out of 5 by from Can’t fine tune important HVAC settings I installed this 4 days ago. Installation was easy as I had an unused C wire on my existing old, round, dumb Honeywell thermostat. I also had no problems connecting to the internet or using the app. I have two issues with the unit. First of all, the display temperature will round to the set temperature when they are within +- 1.5 apart meaning that it always appears that the room temperature is equal to the set temperature when the unit is not off. This is very misleading since it does not represent the actual room temperature the unit is using to turn on/off. The second gripe I have with the unit is that the user cannot control the temperature differential. I am not sure if this thermostat uses 1 or 1.5. Regardless, my AC was running less than 10 minutes most of the time and coming on in 10 minutes. There were times that the unit came on for less than 1 minute (not even sure why this was). Short cycling is not good for HVAC equipment. Between the inaccurate room temperature display and the short cycling, I have uninstalled this unit and installed a smart thermostat from a different manufacturer. I was able to set the differential manually. Now my AC will run for 13-15 minutes and go off for about 20 minutes. In addition, the replacement unit has a compressor minimum run time default of 5 minutes which eliminates short cycling. It also has a feature to let the fan run a little longer after the end of the cycle to dissipate any air left in the duct. It’s a no brainer that the T9 is not worth the money.
