Hey Guys - New to the community as I installed my sprinkler controller yesterday.
Anyway - I've been browsing the community for interesting information and came upon this thread and thought I could contribute.
I've had my weather station up for a few years. It's a Davis VUE.
I use Sandaysoft Cumulus software to track and upload my data to both WeatherUnderground and PWS.
Check it out at http://sandaysoft.com/products/cumulus
It's free and it works great.
I do not have any association with the software or the company, but I've been using it for years and it is reliable and cheap (free)
You can see my station at http://goo.gl/ewnS4K
Hope this helps
