Great thermostat. Love that I can control it while not at home and have it turn on and off with the geofence feature! And maybe it’s all in our head, but the wife and I think it does a better job maintaining a comfortable temp in our home then our older thermostat.
Only have had the Honeywell T9 for a month or so . So far it has helped even out the temp in our home very easy to install. It will let you know what is going on with your system like humidity to high in home great purchase
the main purpose is to have a remote temperature sensor without having to move the wiring & thermostat. The T9 works well for this purpose, except for a few of draw-back: (1) it needs a clock battery back-up as we get frequent power outage; (2) while it can get time setting from wifi-router, our router clock is only set at GMT time, not local time; (3) being wifi-router time dependent, the router has to be on 24/7; (4) screen back-lightning brightness setting doesn't seem to work (too bright)
I love this product. It is simple yet useful. The app to manage the product is user friendly. You all did a great job on this product. The best features is the user friendly app and geofencing.
