Hello all!

In my weewx.conf, if I set Weather Underground to rapid fire, wind gusts are not showing up. I turn off rapid fire and wind gust info now shows up. Any ideas?

I've noticed this as well and I have no idea why. If you are using a VantagePro2, the gust information is included in the URL as "windgustmph".

For example, I just tried it, and here's the URL:

http://rtupdate.wunderground.com/weatherstation/updateweatherstation.php?action=updateraw&ID=KORHOODR3&PASSWORD=XXXXX&softwaretype=weewx-3.0.0a1&baromin=30.142&dewptf=51.5&humidity=085&dateutc=2014-11-03+22%3A54%3A00&realtime=1&UV=0.00&solarradiation=54.00&rtfreq=2.5&dailyrainin=0.00&tempf=55.9&windspeedmph=002&windgustmph=004&rainin=0.00

It's certainly not the first bug we've seen in their API.

Im using Acu-rite's 5 in 1 weather system. This is my first weather station and I wanted to test out the waters before getting something better as the Vantage Pro 2. I was just curious if the script that uploaded to Wunderground maybe was missing the wind gust part in the upload url. Do You know what file handles that? Im curious and wanted to take a look.

Oh. No idea what happens with the Acu-rite.

With the VantagePro, wind gust is not normally included in the LOOP packets (which come every couple of seconds), so the driver, located in bin/weewx/drivers/vantage.py, adds it.

The uploading to WU is handled by a class that puts the new LOOP and archive records in a queue, and another class in a separate thread which receives them, then posts them to the URL. Both are in bin/weewx/restx.py. Class StdWunderground is the former, class AmbientLoopThread for the latter. Both have subclasses.
