There's 10 of those if statements which match the index of 1 - 10
Presumably to match UK standards ? - so why not pass index values as well as colour
Don't mind me beteljuice, I've only just realised that Mark has added in the AQI indexes
My senior eyes have made a fool of me!

because each country/region has the standard as color codes they all differ slightly.

Does not compute Will Robinson !
You are already making threshold / colour decisions on somebodies standard.
The different countries not only have different thresholds / colours, they also may have a different quantity of Indexs.

Don't mind us, we haven't a clue what Mark may / may not be providing ...
Edit: BTW ... I'm still vaguely suspicious of your 24 hr avg - especially pm2.5

Did a little updating now that Cumulus MX calculates the AQI.
Screenshot 2020-10-04 200912.png
Everything is dynamic now, no page refreshes needed!
I also made some icons for it.
(ignore the values. I just made it show all the icons for a screenshot)

Great.
Now I am getting curious about how CMX is handling this. What is given real-time (and where), what is stored (if) and where is it stored (if).
Is this ready to be published or is this still preliminary testing stuff while under development?

Some more testing as yet, though we are close I hope.

@Mapantz and @johnd ?
By pure chance just hit my
Davis test page which uses Maps data and at 5th Oct 14:52 ALL the 'current' values were 0 (zero).
All other values were present and the json did not report an error.
Next, and subsequent passes all OK ...
Edit: Link modified

I just noticed the text in the Davis android app say's "Air Quality: Low" when the AQI is 1.1.
The Air Quality should be "Good", or the boiler plate text needs to change to "Air Quality Index: Low"

I can't see a classification 'Low' in any of the country sets ?

No, because I think the wording in the Davis app is trying to the say the AQI is a "low" number. What it should be saying is that the air quality is "Good" - or whatever the used AQI scale says for its lowest value.

yep confirmed. Worth emailing the developers of the phone app then.

Davis are aware of this issue, but 'low' seems to have been used because it was somehow part of a standard description elsewhere. They are looking at whether there might be an alternative/better option that still fits in with some convention that they're trying to comply with apparently.
