Haha! It's a thermohygrograph.
I am, reluctantly, aware of the inability of the WS-2000 to work with VWS, or Cumulus, or anything else for that matter. I do, however, wonder if there's a way of getting the relevant feed (either from WeatherUnderground or from AmbientWeather.net) back to the PC as a stream from the web, or a reasonably frequent check/download. I will have a play around once I've received the equipment and set it all up. Until then, I can't even access the Ambient Weather site as it wants a MAC address to register.
As an aside, I have been playing with a Vantage Pro 2 Plus which we have recently purchased and installed at work, a system I was considering also purchasing for home. Despite its price tag, the WeatherLinkIP logger is disappointing. Even left doing nothing more than uploading to WeatherLink.com, it's crashing or locking up far too frequently, needing its ethernet cable disconnecting and reconnecting for data to start flowing again. I've opened a support case with the supplier; hopefully this is just a faulty unit and not indicative of the build quality generally.
