Also, just wanted to mention that in my personal opinion there has been a great deal of Home Automation innovation coming from Europe, at least as much as from the U.S. in the same time frame.
Philips is the obvious example. That’s a Dutch company. Full name “Royal Philips of the Netherlands.”
Zwave itself is a European-originated protocol.
And then of course there’s Asian companies (S*****g ).
So I’m not seeing HA as a US-driven technology. Just sayin’…
