I feel like a lot of those common sense ideas could still use streamlining to put in homes. Why can't I live like Rubin? Why should these devices be only for the rich? Hook up a hydrometer and switch and sell it to me as relative humidity aware fan controller.
Nitpick: Hydrometers measure the specific gravity of liquids and are mostly used for beverages such as to calculate a liquid's sugar or alcohol contents.
You're thinking of hygrometers, which measure relative humidity using capacitive, resistive, or gravimetric methods.
I think the hyped euphemisms are carefully crafted to make the people feel important if they buy something. It's a very regular psychological technique in marketing.
