Subject: [PATCH] MSA-608: A specialized bathroom lighting automation.  Turns
 lights on with motion, dims after a custom period of time to give the
 occupant a warning that lights will turn off soon, and then turns off the
 lights unless motion is detected again.  Motion brightens the lights back up.
  Perfect for showering so you don't get left in the dark, and solves the
 problem of motion detection during lights-off dimming transitions.
