@gsuberland If i were ever to do "smart" anything it would be proper SCADA based with DIN rail mount controllers and relay modules not consumer junk.
And designed with careful attention to failure modes in case anything misbehaved.
@azonenberg I think the main gap there is light switches, where you really do need an integrated solution. but otherwise yeah, actual industrial stuff is the way to go.
@gsuberland @azonenberg when builiding the "house enlargement" I wired every new lamp on its own circuit, so now i could centralize light control from the electrical panel. Good past me decision lol.
