wfrog is a Web-based weather station software with nice charts and many ways to publish them on the Web. The architecture is meant to make it very easy to add support for other weather station models and to allow for rendering the weather data in several formats and media using an extensible renderer structure. The processing and memory footprint of wfrog is very low, making it suitable to run on low-power equipment like PC-engine Alix, Cisco NLSU2, or SheevaPlug. The currently supported weather stations are Ambient Weather WS1080, Davis VantagePro, VantagePro2, Elecsa AstroTouch 6975, Fine Offset Electronics H1080, WH1081, WH1090, WH1091, WH2080, WH2081, Freetec PX1117, LaCrosse 2300 series, Oregon Scientific WMR100N, MR200, WMRS200, WMR928X, PCE FWS20, Scientific Sales Pro, Touch Screen Weather Station, Topcom National Geographic 265NE, Watson W8681, and any station using the WESTEP protocol.
