You may also want to think about calibration. Besides absolute calibration there is going to be some offset or other more complicated relationship between your two sensors. Given a "prefer precise if available" this is going to cause some flipping betweeen them. I had a little trouble following this thread, and perhaps StdCalibrate runs before the choice.
But if not, and maybe you want to do this anyway, basically cross-correlated the data from both over a wide range, calculate a mapping function, and put that in the ESP8266 code so that it emits values that are consistent with your other sensor. I did this with an ESP8266 that is measuring a 12V lead-acid battery. While I can calculate expected values from the divider resistors and the data sheet, I ended up just measuring the battery and looking at the raw values and figuring out a divisor, which I stored in a calibration file. -- You received this message because you are subscribed to the Google Groups "weewx-user" group.
