The house I moved into recently has a beige plastic rectangular box
measuring about 2 inches wide by 4 inches long with three long metal
prongs sticking out the back of it, plugged into a matching three hole
socket, located next to a light switch. I can't for the life of me
figure out what this thing is. There is no printing on the outside,
or on the circuit board inside. The face appears to be a button (if
you press on it, it makes a clicking noise).
I do know that ever since I moved in, my front porch lights seem to
turn on by themselves at times. When I unplug the device, they stop
turing on by themselves, and the switch to turn them on does not
work. When the lights do turn on by themselves, they are not 100%
bright, they are dim and flicker.
Maybe this is some type of X10 device for automating the lights? I'd
like to get rid of it, but like I said, unplugging it disables the on/
off switch. The switch, by the way, is on the other side of the
house. The box does not seem to have any control over the switch it
is mounted next to.
Anyone have any idea what this thing is and how to disable it?
