Yes, no or maybe (11 Apr 2006)
This device is designed to eliminate the amount of power wasted by lights being left on unnecessarily. The light switch has three positions that it can be set to; off, permanently on and motion-sensor-activated. Depending on what a room is being used for then you would set the switch accordingly. If it's set to motion sensor and no activity is detected in a room for a preset period, maybe five minutes, the light goes off. This would also save you from having to grapple for a switch in the dark or with full hands. This motion activated setting is ideal for people doing housework or playing children. I would also like to see a light sensor in every room that determines if natural light is adequate and prevents lights from being turned on where they aren't needed.
