Hi there
We’re in the midst of some bad air quality here. I just checked my pws and saw that it is still showing “Good” when it should be “Poor”
I adapted the title of your post, to attract more visitors
Your sensor data is in array[5] of your wl .com v2api data:
https://warehamwx.co.uk/Pws/PWS_listfile.php?file=jsondata/wlcomv2API98440.json&type=json
The sensor is transmitting the data as [aqi_type] => UK COMEAP Daily AQI
And that aqi-type returns the aqi as
[aqi_val] => 7.2910447
So as this script was one of the first versions, it assumes the data is in EPA , the “world-standard” EPA
It simply used the Davis-calculated value to display. And that is correct as long as the sensor is set to “EPA”
The more recent versions understand also EEA for Europe and use the base-data not the Davis calculated AQI.
But that needs two “2009”-release scripts to be changed extensively.
The calculations for a new standard are not trivial either. So that will certainly take more time after March 8.
For now, maybe you can switch the sensor back to report in EPA
