I planned a project for home automation in 2008, and many of my ideas are in the market today (like doorbell video, smart smoke alarms, etc.). However I don't think I missed out because the bar for execution is so high in hardware, and the winners are most often large incumbents with networks effects. Like, even if I pushed out a product, I neither would be able to establish protocol standards nor would I have services like Alexa on top of it. Then of course is economy of scale.
