Researcher has developed, at a cost of less than one dollar, a wireless light switch that runs without batteries, can be installed anywhere on a wall and could reduce the cost of wiring a house by …::A U of A engineering researcher has developed a wireless light switch that could reduce the cost of wiring a house by as much as 50 per cent.
Enocean has been making battery free wireless light switches for almost 15 years. I’ve personally used them for about 8 years and love them. They’re a lot more expensive then the $1 quote in the article but still cheaper than an electrician. They work with a strike to a piezoelectric element to make energy and transmit the signal.
I’ve worked with these professionally, but never actually found a way to purchase them myself. Can you recommend a supplier?
Oh nice. My parent’s doorbell is a wireless one and I thought it was a trick. That they hid the battery and sold it with false advertising.
