This great thermostat ease of setup and monitor of different rooms. My only problem was connection to Wifi its not enough instructions and you can't do anything until the wifi linkup with the Thermostat had reboot my wifi router to get the linkup to happen. That should not have the case you should be able to linkup without reboot of wifi router. And another thing the thermostat does not work with Siri, but I like geofence and the learning capabilities of your temp setting. All and all a good thermostat.
I’ve used ADC, nest and the T6 Pro but the T9 is the best I’ve had.
Installation was straight forward and easy. After installing a few thermostats, I just kinda knew which wires to look for.
What makes this different is how it looks, I can just walk by or look across the room and can easily see the room temperature. The additional sensor can be placed in another room. I think there’s an option to just buy the T9 by itself but I’d recommend paying a little more to get the sensor too. My bedroom gets hot around midnight and the T9 will know to turn on the AC when my bedroom gets too hot. No more waking up sweaty.
The app is nice. Easy to use but I only wish it gives an option for me to run the AC/Heater with a timer.
Seems to work ok , I got this because I was told you could view a daily history I was misinformed apparently you receive a email with a monthly report. I wouldn’t buy it again.
I’ve had my T9 for just over a year now and am very happy with it. The programming options are much better than my older Honeywell thermostat. The app is very easy to use, setup is easy, and programming is very straightforward. Geofencing option is nice, although I don’t really use it. We had a problem balancing the temperature, and the master bedroom and den were always warmer in summer and colder in winter. The sensor feature changed that, and the temperature is now perfectly maintained when we sleep. I also like the fact that I can voice control it with Alexa. Definitely a great product.
I am going to compare this unit to the earlier generation RTH9585W. Smaller display but larger unit makes it look bulky on the wall. Cover plate is not provided in box and per technical support it is not available except through a dealer. Better touch display and user interface. However, lots of wasted space on the primary display it an effort to provide a clean look. Outside temp font is way too small and you have to poke at the unit to see inside humidity. No outside humidity information vs the RTH. Temperature reading may or may not be accurate. One of my two units is 2 degrees off. Calibration will fix this for the display, but not for what Alexa reports out. And it totally screws up the average if you buy an optional sensor as it uses the un-calibrated value for the average.So, compared to earlier product both a giant step forward and a giant step backward.
