QEnergyLoggerDecoder is an application aimed to decoder binary files produced by Voltcraft EnergyLogger 4000 (and maybe 3500, not tested).
My goal is to provide a multi plateform full featured decoding software, because the software provided by Voltcraf is buggy, inefficient and run only on Windows.
You can found source code on GitHub.
On decembre 2018, I published a first version, with binary decoding and export to CSV, quickly followed by a second version with some ehancement (sum up of multiple lines by selecting log lines, GUI ehancement, directory saving after closing software).
You can download binaries for :
