So what will you plug your toaster, tv,fridge, and usb chargers into? I think the NEC requires one plug every 6 feet or one per wall. I could be way of on that. Besides, how many people do you think want to write a script to turn a light on? But, sounds like a good kick stater campaign. I can see the advantages but poe switches are a lot more expensive than electricians. If you can't sell it at home depot it will be very much a niche thing.
