Factory sensor calculating difference and get positive result
I´m calculating a difference of two sensors. This works fine with a factory sensor as its own channel. However it can of course sometimes return negative values. For graphics I would like that the value returned as "difference" would always be positive. What kind of formula would calculate difference of two (or more) channels and return the value always as positive?
