Graupner Ultramat battery charger data logger (mysql) for Linux

This is a small data logger daemon for Graupner Ultramat battery chargers. It was tested with a Ultramat 16s and a Ultra Duo Plus 40. It logs the data on stdout (depending on the debug setting) and stores data in a mysql database (see database.sql for the schema). The data can be accessed via a small web interface. The graphs are created with jpgraph. You can see the example output with graphs from a task below. Tasks are created automatically. Events like "start", "finished" are detected and linked to the current task, here is an example for a cycle:
