Thanks Tom. Signal1 for my station is the signal voltage from a
pyrgometer. Signal2 is the temperature of the pyrgometer sensor (C) and
Signal3 is the long wave intensity (W/m2) calculated by the datalogger. So
if I understand correctly, the weewx engine will pass these values
untouched through the various services and add to the DB as real numbers.
I can then deal with them manually when creating the report.
