I am a new owner of a Davis Vantage View and WeatherlinkIP. Everything worked right out of the box, and I was on WeatherUnderground right away. After close to a $500 investment, I had questions as to why Davis is only updating WeatherUnderground every 15 minutes. After looking at other local stations using Rapid Fire, I too decided I needed a faster response. (Why Faster? Fast is built into my DNA!!!)
After some Internet research, I Decided to test Virtual Weather Station (VWS ver.15).
1) The VWS setup lets me pull data from my Local Area Network, directly from the WeatherlinkIP Ethernet port.
2) The VWS program has superior graphics over the outdated look of the Davis Weatherlink program.
3) In VWS setup, you put in your wunderground station ID and password, turn on rapidfire. Instant success, I now have Rapidfire.
4) There does not seem to be interference with my original WeatherlinkIP function. The Data logger still transmits to Davis Weatherlink site, and Davis still sends data to WeatherUnderground every 15 minutes.
5) VWS has a built in routine that automatically opens the Davis Weatherlink software daily and updates my weatherlink and NOAA database within my local Weatherlink directory.
I have only been running a Weather Station less than a month. and VWS with Rapidfire for 1 day. So far, no issues.
