VPLive is a software application that connects to a Davis Vantage Pro 1 or 2 Weather Station console and displays the live data. It calculates the station pressure (i.e. actual pressure), altimeter pressure, and running averages needed to properly generate and send APRS/CWOP data.
It sends the weather data to the APRS/CWOP system. VPLive also has a feature that will force the VP barometer to update more frequently than the standard 15 minutes. It can run WeatherLink at regular intervals to allow WeatherLink to download the archive data from the console and write it to the archive file. It requires very little CPU time or system resources while running (for example, on an older 500 Mhz Pentium III, VPLive uses around 1/10 of 1% of the CPU's time).
VPLive is freeware.
