Extension to read purpleAir data via json?

[loonsailor]

I'd like to add air quality to my weewx data.  There is a purple air sensor very near to me, but it's not mine and I don't have lan access to it.  It does report to purpleair.com, and I can read the data from there in json format.  I thought I remembered seeing that somebody had done an extension to read from purple air.com, instead of accessing the sensor directly, but I can't find it now.  Does it exist, or was I imagining it?

I have an extension at https://github.com/vinceskahan/weewx-purpleair that you can probably tweak a little to do this.

Thanks, Vince.  I had a look at the extension and it was very helpful.  I've written a python program to get and parse the json for the station, but haven't turned it into a weewx extension, and don't know if / when I will.  I used to be a professional coder, but that was some decades ago.  The coding isn't a barrier for me - I haven't done much Python, but that's not such a biggie - but GitHub is totally new and mysterious!
