The first screen decides whether anyone uses the system
Every household has four or five controls it touches daily and a long tail it touches twice a year. If the opening screen does not put that first group within a tap, people fall back to the wall switch, and an expensive system quietly becomes ornamental.
So the design starts with observation rather than with software. We work out what your household actually reaches for, put exactly that on the first view, and file everything else behind a route that will make sense on the day you finally need it.
