Thank you Paul, but what I need is to trigger a siren, like that ones for warning tornados. My doubt is, how to get the data from my Vantage Pro 2 directly from my network, not from de internet, if I'm using a WLIP uploading data to WL.com. Any ideia?
My ideia is use and arduino to trigger the siren, but this arduino must receive the data from my station.
