Do you live with other people? Kids? I love being able to quickly turn off all the lights in the house as we leave.

I remember automating the lights in my house decades ago (the X10 era!).

The first time I had someone over, I got into bed and hit all-lights-off, only to hear "Hey! I'm in the bathroom and all the lights just went out!"

I just either do that manually or, better yet, make them do it.
