I have just release a mini patch for SMA owners who are using Sunny Data Control to get their data from their inverters. This patch fixes the problem that the daygraph is not generated anymore after a monthswitch.
This error is caused by a change in the layout of the SDMxx files. For some reason the order of the columns in the files has changed. I have updated the dataLoader that it will search for the right column first and then process the data.
To install this fix simply download the file extract it somewhere and overwrite the file in it ( SunnyBeamDataLoader.class ) with the one in your jSunnyReports installation directory.
Update : I have removed the patch, it causes the program to crash.
I’m working on a beta 1.1 release as we speak. stay tuned.
