If you haven't bought the Datalogger yet you could buy the WiFi Logger from Scaled Instruments. It can send your data to multiple sites including Weather Link. com as well as at the same time to your computer and weather software package like the older WeatherLink software (old school looking), original Cumulus (pretty decent), WeatheDisplay (the desktop is hard to read), Weather Solution, Add-In Weather or even VWS (no support but works great and you can configure your own display). Mine sends to WL.com, Weather Underground (ugh) and also (via a fixed IP in the WiFi Logger) to my desktop weather computer to VWS.
The reason I am suggesting using the Wifilogger is that it will send to WL.com and others whether the computer is on or off. Also its setup and learning curve is lower than other methods.
