if all you want is to convert PM2.5 using the US EPA AQI tables i.e. not get
variants or labels, see weewx extension
http://geddy.id.au/downloads/weewx-aqixtypes-0.0.2.tar.gz
<http://geddy.id.au/downloads/weewx-aqixtypes-0.0.2.tar.gz>
(haven’t got around to putting lots of stuff up on github yet)
configure in weewx.conf by adding
[Engine]
xtypes_services = ..., user.aqixtypes.US_EPA
and map the PM2.5 inputs (instant or 24hr avg or both) to outputs e.g.
[AQIXTypes]
[[map]]
aqi_pm2_51_24h_avg = pm2_51_24h_avg
aqi_pm2_52_24h_avg = pm2_52_24h_avg
aqi_pm2_51_instant = pm2_5
aqi_pm2_52_instant = pm2_52
and optionally force the xtypes to be generated into archive packets by
[StdWXCalculate]
[[Calculations]]
aqi_pm2_51_24h_avg = software, archive
aqi_pm2_52_24h_avg = software, archive
aqi_pm2_51_instant = software, archive
aqi_pm2_52_instant = software, archive
