I joined Weathercloud.net.
I am using the add on Brian is producing for Wdisplay, it is in its beta, but it shows promise and it has the ability to send data to this site.
I also see they have it so that if you have the Weatherlink IP you can have them poll your site and snag the data that way as well or if you use Wlink itself there is a module.
What I notice that in Iowa, it is only me right now. I can see some advantage of this, checking the weather around the state on several variables and how it might impact us. I know there is a lot of stuff out there that does it similar, but if you are like me, then we always want to see what else is out there.
