I agree that DIY isn't a great solution for most people, especially if it involves writing your own software. But as the Home Assistant community grows there are more and more pre-built, highly capable open-source modules for Pi's and ESP8266's and whatever that entrepreneurs could start selling, installing, and servicing them at normal people's homes for megabucks. I think it's a big market.
