Thanks for the help, I've got this running pretty well now, however I have
an issue with formatting a variable. The WXSim developer has told me the
expected rain value is an accumulator for the year. I created a $rainacc so
the template code looks like this:
#set $rainacc = $year.rain.sum.raw - $month.rain.sum.raw
#for $record in $month.records
#set $rainacc = $rainacc + $record.rain.raw
$record.dateTime.format("%d/%m/%Y
%H:%M"),$record.outTemp.format(add_label=False),$record.outHumidity.format(add_label=False),$record.dewpoint.format(add_label=False),$record.windSpeed.format(add_label=False),$record.windGust.format(add_label=False),$record.windDir.format(add_label=False),0,0,$record.barometer.format(add_label=False),$rainacc,0,0,0,0,0,0,$record.radiation.format(add_label=False),0
#end for
This works, however the output for rain is to 13 decimals:
1083.8000001314047. No matter what I do I can't seem to format it to 2
decimal places. I have tried $rainacc.round(2)and $rainacc.format(%.2f)
