Can someone please tell me if it is possible to use this Watson 8681 Pro II PWS to connect to Windy? It's currently uploading data to Wunderground directly from the base station over WiFi, I don't really want to use a PC/MAC as an interface if I can avoid it.

I've registered with Windy and I can see my API key, but what do I do next?

Any help most welcome - Tim.
