What's the target market of your business? I'm doing a DIY solar setup, plus a bunch of liberty-respecting automation, and often lament that there aren't better ways to make such things serviceable by contractors (when I'm gone, etc). It feels like every commercial offering I've seen is for extremely rich people's "dream houses", deploying expensive niche-commercial solutions in a very top-down manner (lots of homeruns of narrow-purpose cables to multiple racks in a centralized control room, etc).
