Very pretty mock-ups, in that “75% whitespace and 25% content” kind of way …
I started automating my home in 2006 and, during my early years, making a dashboard UI seemed … important. Having an attractive wall-mounted touchscreen was what signaled to guests that our home was “smart”. Just look! The screen wakes up when we arrive home! Unlock a door and the little padlock icon on the screen changes to an open padlock! Oooh! Aaaah!
When the touchscreen died, it was removed and replaced by an even more attractive … poster. Thirteen years later, even the UI on my phone is a minimalist “Just the facts, ma’am!” (75% content, 25% whitespace).
Nevertheless, can’t deny the mock-ups would impress the guests.
