Any way to convert the Light level output from ohms to LUX? (Light_Level: 71190.48 (Ohms))
There is a line in the "[Calibration]" section of cfg/supports.cfg which you can uncomment (by removing the # at the beginning) to convert to Lux. Don't forget to enable the calibration support plugin a couple of lines higher up, too. NOTE: I didn't create that calibration function, and all the evidence I've seen to date suggests that each AirPi needs to be calibrated individually, and so the function is unlikely to result in an accurate conversion for you.
My temp on both sensors on my AirPi always report the temp to be way higher than it actually is. For example, right now the room is 69 F but the BMP085 reports 95 F while the DHT reports 92.66 F. It's always been this way. Does each sensor need calibration? and if so what's the right way to do that? I'm guessing that going into supports.cfg and subtracting a flat number (such as subtracting 26 from the BMP085 would end up being in accurate as the temperature lowers)
The temperature sensors shouldn't need calibration as far as I'm aware. Mine always read a little bit off (2 or 3 deg C) but not that far. You're right about the potential solution though - find their offset against a known-good thermometer and set up calibration functions. You just need to hope that the difference is always the same, otherwise things get more complicated!
