I like it. I like the technology and the simple work around.This may solve peroneustertius's light on Shabbos problem, but I think he should check if his sensors do anything else.
here is what you do for the fridge part---Buy powerful magnets from HD and put them above the spot that has the magnet connector.Here is a pic--hope that helps
classically one would assume there is a button that get pushed in to tell the light that the door is closed---but on these there is just a pair of magnets--one on the frame and one in each door---so when you put your own magnet on the fridge part--the fridge always thinks the door is closed--and lights dont turn on YAY
it's good to be a Lubavitcher
i would like to publicly thank yakovwogi for the idea. This indeed did work. Hopefully it will last through a shabbos and not magically detach.
