@snell the PWS's that use the ObserverIP module (WS-800, WS-1401, etc) they all have IP in their names. The ObserverIP is a little black box that plugs into ethernet and receives the radio signal from the PWS or console.
There is a web interface. You can scrape it. It WILL CRASH the observer IP if you scrape it too often (less than once a minute) as the little box has a memory leak and it will eventually lock up hard and require a power cycle. Many use a power plug to cycle power nightly... kinda like the HE hub right? Anyways. Though you should be aware.
