Free weather station software!
Cumulus is free software for retrieving, storing and displaying data from an electronic Automatic Weather Station (AWS).

Cumulus will store full weather records, along with daily, monthly, annual and all-time records, and graphical data. Cumulus can upload its data to a web server and comes packaged with templated web pages for this purpose. Cumulus also supports automatic uploads to Weather Underground and CWOP/APRS.
Cumulus works with the Davis Vantage Pro and Vantage Pro2 weather stations (and the new Vantage Vue), the Oregon Scientific WMR-928 and WM-918 weather stations (and related models), Fine Offset stations such as the WH1081, and the La Crosse WS-2300 range.
Warning: If your weather station is a La Crosse and it is connected using a serial/USB adapter, then you will probably have problems using it with Cumulus, in that you will get erroneous data from time to time – this is a common problem with these stations when used in this way. There doesn’t seem to be anything I can do about this. For this reason, I am sorry to say that I cannot support the use of Cumulus in this way. Note that even if you are using a direct serial connection, I don’t actually own a La Crosse weather station, and there is no official documentation available for the protocol, so I am only able to give limited support to these stations, and if you have any problems it is unlikely that I will be able to anything about it.
