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 :groan:
Don't mind me beteljuice, I've only just realised that Mark has added in the AQI indexes :groan:

My senior eyes have made a fool of me! :oops:

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. :D

(ignore the values. I just made it show all the icons for a screenshot)

Great. :D

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.

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.
