Hi Ian,

That looks good, and it works on an iPad!, I'll have to install that too.

I have an old iPad 1 mounted on the wall to serve as the dashboard for weather so the Weather34 skin will do nicely for that. It was using an older version of that skin from somewhere else but it has issues now.

thanks

Tim

Tim,

This is how I did it for the Weather34 skin: -

https://github.com/steepleian/weewx-Weather34/blob/master/www/worldaqitop.php 
(US/World)

And

https://github.com/steepleian/weewx-Weather34/blob/master/www/daqitop.php (UK Specific)

See on the website, two top row modules in the centre.

https://claydonsweather.org.uk/weewx/weather34/index.php

Also if you click in the centre of either module, you will get a pop-up info window.

Hi Daniel,

All cool but you are plotting PM not AQI .

AQI is a value calculated from either a single PM type  or multiple PM types.

https://aqicn.org/calculator

https://en.wikipedia.org/wiki/Air_quality_index

The AQI plugin is supposed to do that and it creates a new db to save the AQI values in it.

I have an Ecowitt PM2.5 monitor and that data is being saved to the weewx db, I'm investigating how I can calculate AQI from that data using the AQI plugin and then show the actual AQI via the Belchertown skin.

I've just been wondering if anyone else has done that, and if so, how ?

If not one has done that yet, I'll plod on and eventually work it out :)

cheers

Tim

I  have it working with my PurpleAir and the weewx-purple extension.

All I had to do was add pm2_5 to my sensor list and create a graph:
station_observations = barometer, dewpoint, outHumidity, rainWithRainRate, pm2_5, radiation

And in /etc/weewx/skins/Belchertown/graphs.conf:
 [[chart7]]
     title = Air Quality
     [[[pm2_5]]]
       name = AQI PM 2.5
       zIndex = 1
       color = "#becc00"
     [[[pm1_0]]]
       name = AQI PM 1.0
       zIndex = 1
       color = "#ffc83f"
     [[[pm10_0]]]
       name = AQI PM 10.0
       zIndex = 1
       color = "#c83fff"
