I saw that, too. The signal has to work with some electricity! I was wondering if just the physical movement of the switch would create sufficient electricity to power the signal ...... the owner lived in a condo and shared the ceiling with a neighbor above, running wiring was really difficult. The answer was installing an additional hard wired electrode that sends a signal to a switch on the wall and the switch doesn't even need batteries to send the on circuit and off circuit signal
I think You are Right, Ducks'. These innovations are making everything more energy efficient and moving us towards alternatives to the gross power generation models used for over a century. I can so easily remember the complaints about fluorescent. I don't mean the compact spirals. I mean the tubes that went in the new supermarkets and on signs. They all need improvements, yes. And, the patents locking in high prices do lock out low income people.
