Betting it’s a module for EnOcean in that, they’ve been doing energy harvesting switches for over twenty years now. I think the new part of this proposed system is that power is provided wirelessly so each switch can be cheaper than the fancy mechanically powered transmitters. I do wonder how much energy it ends up wasting though.
