Hi all
I'm trying to get Filepile working but have come across an error that I
don't understand. Any help appreciated. The database has been extended with
fields to match those below in the data file - am I just missing spaces in
the layout? Should it be AQI25 = 1.60 etc etc
Many thanks
This is my data file;
AQI25=1.60
AQI100=3.30
AQIIndex=6
AQICO2=683
This is my stanza in weewx.conf
##############################################################################
# This section is for FilePile
[FilePile]
filename = /home/pi/AQIData.txt
unit_system = METRIC
##############################################################################
This is my filepile.py (modified from original to suit)
