# PIR motion sensor (AM312): case light and nozzle LEDs while someone is near
#
# The AM312 keeps its output on as long as it sees movement: press = motion,
# release = no more motion. The timeout starts at the release, so the lights
# stay on while someone works at the printer.
#
#   someone near:              case light near_value, nozzle LEDs white
#   nobody near, print/pause:  case light print_value, nozzle LEDs off
#   nobody near, idle:         case light idle_value, nozzle LEDs off,
#                              logo and Box Turtle logo dim (_STATUS ready)
#
# CASELIGHT MODE=ON [VALUE=0.5] | OFF | AUTO overrides the sensor until the
# next Klipper restart. Setting the case light in Mainsail only lasts until
# the next motion.
