Harvesting stray RF energy sounds like a cool technology for certain niche applications.

But for switching lights in particular, I much prefer smart bulbs vs installing stuff to put the switches in nicer places. It also makes it easy to dim a room or the entire house in the evening.

Wouldn't it make more sense to make the light switch the smart part then you can have cheap bulbs. You want the technical bit to be the bit that doesn't wear out and has to be replaced.

As someone who has smart bulbs and smart switches. The switches are a 1000x more preferable. It’s nice to be able to use my phone, but it fucking sucks needing to use my phone every time I want to control them.

That's where occupancy sensors shine. I generally don't have to touch my phone or switches.
