If someone patents in interface, it's gone from every other vendor. And since it's the "best" it's worth more, so a $5 item is now a $100 item (gotta pay back that engineering time). It's not expensive because it's mechanically robust or physically challenging to build the parts, it's because of the monopolistic lock in that each standard brings.
Plus, there are no (useful, universal) standards for home automation. Partly because it's just too wide open, partly because shit is changing all the time. How often has the primary power distribution in a home changed in your lifetime (0)? How many times has TV transmission (once, maybe twice)? How many times has network requirements changed (I've run out of fingers)? A simple, end-user programmable, extensible system available on a commodity basis from multiple vendors simply doesn't exist.
FWIW, 20 years is a blink of an eye for a house. I regularly run across basically the same dumb electrical components in 1950s buildings that are being installed in today's brand new homes. And multiple manufacturers offer interchangeable parts for houses built today and 60+ years ago. Until Smart stops meaning outrageously overpriced for the hardware provided, it's never going to be mainstream.
