OK I've found some
XP software that will allow update to a web /ftp site etc. It's not freeware but the trial is free. There's also FAQ's on the various steps required to build the web pages etc. (It also works on the vantage Pro John). I have it working on a different machine to the one that the weatherstation is connected to and it's reading the data file across the network and displaying very nicely! It works by reading the .dat file that the easyweather software creates. I've also noticed on some weather forums where they have their local weather data displayed in their sigs.
