Too small of a font for the temperature to which you want it set. I have to put on my reading glasses to see it. The backlight is too bright at night, stays on too long and that time is not adjustable.
The app is buggy on start-up. The home screen flickers, scrolls, and flashes as it's trying to start up. The thermostat doesn't always follow the schedule
I am pleasantly surprised by this tstat. Easy enough to use. The wireless for remote monitoring is solid. When it was set up the tech made it so I have to switch modes from heat to cool. There is an “ advanced setting” that will make heat to cold happen on “auto” but then I don’t know how to set the minimum temperature differentials for the auto mode to work so I’ll stick with manual mode switching.
