Pros: works as advertised, drives to remote sensor temp as intended during set time, geo fence (off when away) useful. Touch screen response good. Adjust temp from app good.
Cons: a) can’t display time instead of temp on main screen when idle, b) app can’t show temp and heat/cool activity as graph like radio thermostat app does c) Cannot increase tolerance - the temperature “band” before heat/cool goes back on to maintain temp. At first was worried about more frequent cycling than old tstat, and that it would wear out old AC. Seems ok for now.
The T9 thermostat work great but finding that the room sensor I brought after seem to not give the right room temperature to the thermostat, end up not using the room sensor and everything working fine again with the thermostat
Like the fact that I don't have to get out of bed to turn out of and on and I can turn it on when I'm 30 minutes from home to make sure the house is nice and cool when I get home or the ability to turn it off while I'm on the road of I forgot to do that before leaving the house that way the A/C's not running all day when no one's at home.
