Rob,
Is analog scaling from the Dashboard on the backlog, preferably one that accepts a math function (y = , or selects a math function from a list and parameters in dialog boxes?
Example in this post: LM393 photoresitor - #2 by kreggly
For thermistors, an implementation of the Steinhart or Beta formulas, etc.
Load sensors are fairly linear, so linear interpolations like the photoresistor could be used, but may want to show the raw value in a settings dialog, so that a zero value can be entered in a dialog box.
Cheers,
Craig
