Re: [weewx-user] Accessing Database From Service Extension

[Carter Humphreys]

Thanks. So the calculation of AQI I have in my extension already, however I need the average value from the weewx database of the PM2.5 for a more realistic AQI. I essentially want to create a new variable that is the AQI based on the rolling 24-hour average and add that to the database.

What I want to do is calculate the air quality index (AQI) based on the PM2.5 data. The EPA references the correct way of doing this as using the 24-hour average PM2.5. So my question is, is there a way for an extension to access the weewx database a pull the average value of a variable over the last 24 hours? -- You received this message because you are subscribed to the Google Groups "weewx-user" group.
