The app works like a charm. I don't use a ton of the scheduling features, but it's nice to know they're there. For me, a nice dance between bare-bones and all the bells and whistles.
Our new thermostats were installed when we needed to replace our HVAC equipment and we are finding them to be easy to use. Especially like the ability to control both thermostats from my phone. They are also attractive on the wall with the screen blank until tapped.
