The Resideo App has been working flawlessly for 3 months whether I'm local or out of town. It integrates just fine with the Honeywell Pro Series and also have a schedule setup for time of day temp. function thru the app. I use the Fan, Mode, and Alerts and have never had any issues.
Was glad we replaced our old thermostat now we can control it from anywhere we are with a power company tha charges EXTRA for power used during their peak hours so now I have conrol of this problem. Very easy to setup and use.
