Initially it worked fine but soon it would take too long before starting the AC when setting a lower temperature. When starting the AC from the app, again sometimes takes to long to actually start cooling. Also sometimes the temperature set in the app doesn't reflect on the thermostat!
Unless I missed something big, and that's always a possibility, I am tremendously disappointed. I though I was going to get a dashboard where I could program the entire setup. Instead I can bump the current temp up or down. I want a weeks worth, 4 or 5 time blocks, heat and cool, fan on or off or auto, from a setup screen that is easy to read.
