I personally use NixOS for everything, so I totally get the want for versioned config as an advanced user. But I did the opposite and put HA on a raspberry pi.

I personally use NixOS for everything, so I totally get the want for versioned config as an advanced user. But I did the opposite and put HA on a raspberry pi. If I die or am incapacitated I want my wife and kids to still be able to manage the lights and other automations. I'd also probably just leave the pi with the house if I sold it, since it is an integral piece needed to fully utilize a lot of installed hardware in the house. I mean I wouldn't take out the sprinkler computer either.
