Zero details bullshit article. How would it reduce the cost by 50% considering you’d need a smart relay board with connectivity and then wire all the light fixtures to them OR have separate wireless relay boards at every light fixture OR have smart bulbs and a gateway.

Copper wires are expensive. And you need to house those wires in aluminum pipes. That's a lot of metal that you no longer need to buy. Especially considering how many light switches in our homes.

Presumably they are in an area that requires armored cable, such as Chicago
