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.

They need to be powered on all the time and you still need the switches either way, unless you design your home to be solely smartphone controlled but nobody does that.
