That’s completely different there are numerous times I change my temp I my house when I’m not there. Go on vacation and the temp drops so instead of air I need heat or vice verse. The app is a nice addition for thermostats. Not headlights though.I just installed a Nest thermostat in my home but left off the phone app function. Why do I need to adjust the thermostat in my home when i'm not there? I think they get people to jump all over crap you can do on your phone even if it's for the most part pointless.
