This is the third Honeywell wifi thermostat installed in our homes. The ease of use and simple remote access is the main reasons I have stuck with Honeywell.
The interface is very nice on both the mobile app and device and it was relatively easy to setup. BUT my complaint is the delay in turning on, off, when hitting a set temperature. For example, I set Cool to 78 the temperature drops to 78 and the air will not shut off for another 5 minutes. I can then set System to off and again it takes another few minutes before it actually shuts down
The most flexible, practical, and easy to use thermostat I have owned to date. I originally purchased so I could remotely monitor and control our vacation home. It worked so well that I had to get a second one for our primary home. So easy to switch to vacation mode while we go back and forth. Simple to install if you have some basic electrical knowledge. Time will tell if they hold up to Central Florida's electrical storns. So far so good, made it thru two big storms. The screens look great when you program custom colors. The factory color templates look blurry and smeared compared to custom settings.
