Here is the scoop. (And the AppleScript code is provided further below for those interested. I am in touch will the developer for Weathersnoop and will provide them details to hopefully add Windy Upload to the product once this is working.)

Summary: I have created a station, gotten an API key, and have been uploading every 7 minutes for two+ weeks whilst trying everything to fix. The station shows on Windy, and even shows when the latest update had occurred (e.g., 3 mins ago), but no weather data.

The details: I am uploading via the API documentation:

https://stations.windy.com/pws/update/MYAPIKEY?winddir=113&windspeedmph=7.0&windgustmph=11.0&tempf=54.0&rainin=0.41&baromin=28.68&dewptf=49.9&humidity=86&stationId=0

I am getting "SUCCESS" replies back (or other messages if I try to do so under 5 mins) so I know it's communicating.

It shows within the Windy.com UI, for example (see the "pws Round Hill, Overland Park, KS" on the lower right:

However, obviously no weather data. And here is what I get as well when I go to my station:

Here is what I get when I retrieve my station data back from the API:

From: https://stations.windy.com/pws/station/[myAPIKey]/0

{"header":{"name":"Round Hill, Overland Park, KS","content":{"url":"","text":"Greg Fay"},"agl_temp":10,"agl_wind":10,"elev_m":322.48,"lat":38.97056060774817,"lon":-94.64931964874268,"stationType":"Davis Vantage Pro 2","shareOption":"Open","id":"f065e403","stationId":0,"type":"pws","updated":"2020-05-04T08:00:55.962Z","observation":{"avgFreqMin":7.054794520547945,"records":1,"avgDelayMin":5,"sumRows":146,"default":false,"latestObs":"2020-05-04T04:15:39.629Z"},"observationUpdated":"2020-05-04T04:15:39.629Z"},"data":null}

I'm assuming "data" being "null" is a bad thing. ;)

Things I've tried based on dozens of other articles of people having issues:

• Waiting days.
• Forum posts (in the wrong area I think).
• Adding stationid.
• Adding the latitude and longitude.
• Using a new API Key.
• Deleting and recreating the entire station and using the new API Key.
• Waiting weeks. ;)

FYI, here is the code. I've added lots of debugging logic to it:

tell application "WeatherSnoop 5"
	tell agent of first document
		--display dialog "Temp: " & value of weather property "Outdoor Temperature"
		set MyAPIKey to "[myAPIKey]"
		set WeatherParams to ¬
			"winddir=" & value of weather property "Wind Direction" & ¬
			"&windspeedmph=" & value of weather property "Wind Speed" & ¬
			"&windgustmph=" & value of weather property "10 Minute Wind Gust" & ¬
			"&tempf=" & value of weather property "Outdoor Temperature" & ¬
			"&rainin=" & value of weather property "Day Rain" & ¬
			"&baromin=" & value of weather property "Barometric Pressure (Absolute)" & ¬
			"&dewptf=" & value of weather property "Outdoor Dew Point" & ¬
			"&humidity=" & value of weather property "Outdoor Humidity"
		set WindyURL to "curl https://stations.windy.com/pws/update/" & MyAPIKey & "?" & WeatherParams & "&stationId=0"
		set WindyURLsafe to "https://stations.windy.com/pws/update/" & "MYAPIKEY" & "?" & WeatherParams & "&stationId=0"
		
		set myResult to do shell script WindyURL
		
	end tell
end tell

set myTime to do shell script "date "
set myString to "----------Timestamp: " & myTime & "-----------" & linefeed & WindyURLsafe & linefeed & myResult
copy myString to stdout

...and here is a sample output (intentionally showing one with a "too soon" error:
