Configure Weewx-AQI with Ecowitt PM2_5
« on: July 02, 2021, 04:42:36 PM »
I was thinking of adding an Air Quality display to my Weewx running the Belchertown skin and someone pointed me to this extension Weewx-AQI, but it is configured to work with a Purple Air sensor.

I was wondering if anyone had the settings, or a guide, to configuring that extension, but with the Ecowitt PM2_5 sensor? I am not too good on coding and my Google searches haven't had much luck finding a guide or anything to getting it working with the Ecowitt sensor, so I thought I would ask here.

I'm not working with the Belchertown skin, but in principle you should be able to depict - at least as a table or as a graph - all values from the weewx database.
The WH41/43 or the WH45 with its PM2.5 and PM10 observations should be stored in the weewx database if you use the proper database schema and have either created the missing entries/rows or have repurposed other fields/rows to accommodate the AQ observations.

That said, if you own a GW1000 the fields/values are available and only need to be placed on the skin. The fields and their names can be found in the Gary's GW1000 wiki at (field map).

What I would do is go through the skin.conf and related files of the Belchertown skin and see how e.g. temperature or humidity are put into a graph, copy that  section and then add the pm_25 etc. fields by renaming the copied tempout etc. fields. That should work.
