"When you enter home - based on presence, time of day, ambient illuminance, barometric pressure, temperature what do you want to happen?"

Pretty hard to think of anything I want to happen upon returning home that depends on barometric pressure. I can't really understand what you're getting at here more generally either, though.

When I return home, I (1) put down anything I might be carrying, (2) greet the dog, (3) maybe turn on a couple of lights, (4) maybe take off a coat or jacket, then (5) just sort of go about my life, doing whatever it is that I need or want to do.

So genuine question: what complicated series of events do you want to happen when you return home?
