Nothing showing up yet, so perhaps still a Cumulus setting or WU set up issue? Have you double checked the Station ID and Password in Cumulus Configuration Internet Weather Underground is identical as your settings in the Weather Underground site?

Well, I figured out I wasn't reflecting the daylight saving time change into my WS2090, so I fixed the time misalignment. Also, my coordinates in Cumulus were off (used 'E' instead of 'W')
I know...lame on my part. 
Now, with Cumulus up and running well, my actual station out in the field may need a battery change. Cumulus is saying it's not picking up the censor. Almost there indeed!
