[[Calculations]] on archive record not loop packet?

[Graham Eddy]

my reading of the 4.3.0 source is that [[Calculations]] calculates the specified xtypes on each loop packet. is there a simple way now, or is it in plan, to be able to have them calculated for archive records only?

i do not want to calculate AQI from averaged pollutant values except when the averages are updated, which for me is at the end of each archive interval. i have written a data service to call the xtypes each archive record, but i would prefer StdWXCalculate handled it for me with ‘= software’ declarations

Hi, Graham

Seems like a reasonable thing to do but, no, there is no way at this point. Perhaps the [[Calculations]] section should be expanded to:

[StdWXCalculate]

  [[Calculations]]

    aqi = software, record

That is, it takes an optional second positional parameter that can be one of 'loop', 'record', or 'both'. The default would be 'both'.

‘push request’ created (i think… github said something about deprecated) for ‘loop’ and/or ‘archive’

i.e. aqi=software (defaults to both bindings) or aqi=software,loop or aqi=software,archive or aqi=software,loop,archive
