Value For Money

Frequently loses connection and has difficulty staying connected to wi-fi and app.

Can be accurate, but may drop offline or show inconsistencies.

Temperature readings can be unreliable and difficult to control.

Offers seamless remote access, but can be slow and glitchy.

Takes around 15 minutes with minimal issues.

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.

The setup options are limited. The issue is that if I want to use geofencing mode, I'm not able to set different temperatures at different times of the day while I'm at home. I use Arlo cameras and I can combine a schedule with the geofencing option.

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 arenât accurate

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

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.

Can't fine tune important HVAC settings

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.

Needs more work!

I had 3 9580 thermostats, 2 in old home and one in a vacation home. Builder installed 2 T9âs in new home.. Now I need to use two different mobile apps remotely use! Software for T9 freezes. Software for T9 needs fixing. 9580 much more stable.

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!

There is a problem with the thermometer on this thermostat - sometimes when I set it to 24C I notice it getting really really cold so I manually turn the system off.  Immediately, the thermostat display drops to 22C!  It's like the thermometer sensor doesn't communicate with the thermostat to tell it to shut off so it keeps running or, it just doesn't update close enough to "real time".  This is a problem but the bigger problem has been the completely unhelpful help line.  I took the time to document what was happening and go through problem solving with an online chat.  I followed up with the trouble shooting steps suggested but did not gain any more info as a result.   This is a defective product and after another hour on the phone (after waiting on hold for some time too, of course) was no further ahead.  It should be replaced but I've given up and will cut my losses and get another one.

defective product and unhelpful help desk

We built a new home and I changed the dumb thermostat that the HVAC company put in to 3 - T9 with sensors. The app is getting worse and worse. Geofencing was sketchy but seems to be working a little better. Now when you change the temp on the app, about 10 seconds later it changes back to the old temp. I was a long time Nest customer and think I made a mistake going Honeywell. Reviews were good but reality is a different tune. Wish they would buy them back.

Not consistent - should have stuck with Nest
