How do I post data for a home built weather station that includes PM 2.5 and PM 10?

Hi, I am trying to do exactly the same thing, without success.
If this can help, from this link http://wiki.wunderground.com/index.php/PWS_-_Upload_Protocol it seems (Pollution Fields section) that one should add the codes "AqPM10", ... to the usual HTTP GET query for uploading data, anyway it does not seem to work.
The actual implemented command parses only the parameters shown in "usage" answer.
May be there is another php script to call to upload extended data.
I sent a support request.
Stay in touch,
Luca
 

Hi,
today I checked again my personal weather station page and I noticed that, in some way, now weather underground wps app seems to acquire PM data and to show them in the graph view! I have not changed anything in the upload method of my software. There are no PM columns available yet, in the table view. However, it seems that now they are at least accepting and storing data.
Please, look for IFALCONA6 wps and give it a look. There are some spikes in the PM graphs, but I think that they come from some unmanaged error occurring in my software at power down and subsequent restart. I will check it.
Try again and let me know if it works also for you.
Regards,
Luca
