1. A system, comprising:
- a portable housing;
at least one battery in the housing;
at least one light emitting diode (LED) on the housing and electrically connectable to the battery;
an adhesive layer that can be detachably stuck on a wall of a room near a light switch assembly electrically connected to an ac power grid; and
a motion detector in the housing, the motion detector providing a signal for activating the LED when the room is dark and motion is sensed such that when the housing is positioned near the light switch assembly, the light switch assembly is illuminated by the LED without connecting the system to the ac power grid.

Abstract
A small portable housing has a battery-powered LED and an adhesive layer that can be detachably stuck on a wall near a light switch. A PIR motion detector in the housing activates the LED when the room is dark and motion is sensed.

8. A method for facilitating locating a light switch in the dark, the light switch being connected to an ac power grid, the method comprising:
-
disposing a motion detector in a housing;
adhering the housing to a wall next to the light switch without connecting the housing or contents therein to the ac power grid; and
energizing a light on the housing at least in part in response to signals from the motion detector such that a person can see the light switch. - View Dependent Claims (9, 10, 11, 12, 13)

14. A system, comprising:
-
a motion detector in a housing and generating a signal representative of motion;
a wireless transmitter in the housing;
a controlled device distanced from the housing and connected to a wireless receiver, the transmitter sending commands to the receiver to control the controlled device at least in part based on signals from the motion detector. - View Dependent Claims (15, 16, 17, 18, 19, 20)
