A driver for the LaCrosse WS-2300

Ws2300 manipulates the LaCrosse WS-2300 weather station via its RS232 interface. It can read and write values, and can continuously log data from WS-2300 to a file or SQL database.

I use this program with a WS-2300, and others have reported it working on a WS-2357. It probably works with every LaCrosse WS-23xx weather station that connects to a computer using serial or USB.

The primary differences between Ws2300 and LaCrosse's software is:


There is a man page, a change log, a README.txt and a file describing the WS-2300's memory map. The WS-2300 weather station hardware is described at its home page.

Ws2300 is based on open2300, and owes a lot to it. Open2300 was developed by Kenneth Lavrsen.

The WS-2300 was reverse engineered mainly by people on the German language Weather Station Forum, which is located at:
