OK what is SOL?

**** Out of Luck.

I have had a bit of experience with this sort of thing myself. Its
basically got a timer, high/low settings(which is just 1 or 2 elements on)
some king of water sensor gadget and the usual door switches etc.

OK. I would try to treat the dryness sensor as a 'lump' and deal with
everything else which is easier.
