To me this is one of those examples where you might re-think the whole problem from the ground up, then take a step back when realizing the absolute solution is not the perfect solution. Take for example, the clap-it lights; while yes it requires less effort than walking over and flicking the switch, it's also extremely annoying to do. Likewise, I would get really annoyed when lights go on and off according to where I walk. Of course I don't have a Nest either and yet it does fill a need for some people.
