I've seen $250 humidity detecting fans (Broan?). I have a timer on my bath
fans, and motion detectors on my hallway lights (installed when my dad was
dying), so I can't believe they can't make a wall switch which detects
humidity. ANyone see one? Couldn't find one with google. Besides the
bathrooms, I'd wonder if I can't have one for the house when I'm away and
don't want to have the heat or cool on just to prevent mildew. I hadn't used
cooling in years and the upstairs duct perspired onto my ceiling.

I doubt you'll ever find one. To detect humidity, air must circulate
over the sensor. I don't see how to do that in a jamb box. A quick
search* turns up

Googling "wall mount humidistat" will return hits like the following:

Broan DH100W
Honeywell H46C
Honeywell H8908B
Honeywell H600A
Ranco J10-821

There are many humdiity detectors available today. None as a switch,
as they require a good air flow (and a switch won't have any air-flow)
but you can mount them in unobtrusive places (such as near the fan) if
you wanted, and use the wall switch as a master on/off.
