I apologize if this is off topic, since owfs seems to handle DS2450 just fine, as best I can surmise.
I purchased a "HVAC Monitor Kit" from Hobby Boards. The description of the board states that it can measure any voltage up to 28V AC or DC. The design has a diode and a resistive voltage divider (100K/1M) on the front-end of the DS2450 voltage inputs. For the signal I want to monitor, my DVM measures 15V AC at the terminal lug of the HVAC Monitor. However, via owfs HTTP, I see various voltages between 240 mV and 1.5V, seems to be all over the place, like maybe a sinusoid :-) Can anyone offer any tips on how I might measure an AC voltage with this thing?
