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 use something like this for my wireless doorbell because people kept stealing the battery. I've had it for years and it works really well.

I know times are tough but who TF out here stealing batteries

[–] ForgotAboutDre 7 points 11 months ago (1 children)

It's probably someone in his house. They either think the door bell is too loud or need the batteries for another device.

Ah yes those "other devices"... check the wife's nightstand

I've worked with these professionally, but never actually found a way to purchase them myself. Can you recommend a supplier?

Various companies repackage or license the enOcean parts. I've used this one from Amazon for about 6 years and haven't thought about it. I've also used others from this brand for 8+ years and had no issues. I bought an old house around Boston that had power in the ceilings but no switches anywhere so this worked perfectly for me and I was able to do it all myself.

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.
