Energy Logger 4000

Recently I bought at the Voltcraft Energy Logger 4000. It was a daydeal, €20,- each. Currently it is monitoring my lab servers.

To read the log files and write them to some database (e.g. MySql) i wrote and C#.NET application.

The application currently processes log files only. You can write your own function to convert ‘LogLines’ to your dataset.

After VELReader.Read(“C:\log.bin”) is called, and list of loglines is updated. You can acces those lines at VELReader.Log[array/list].

    Thank you Robin ! Now I can read Power and other things, bin-files, with your SW.
    I have difficulties to read with Energy Logger Viewer the charts. I cannot change Power value to 2 kW because there is 16 kW spikes. Now I am using Win7 and I think that it worked better with XP. I am 63 and I am not very good to bild up SW-programs.

    Hello Robin,

    I just bought Voltcraft Energy Logger 4000 and I am having issues with reading the .bin files. I used your application and I only get the data on the INFO section (left side). I don’t get anything on the DATA section. Do you know what the problem might be?

      Hello Mary,

      The Voltcraft Energy Logger 4000 probably generates faulty .bin files.
      Please try resetting the device. Or reformat the sd-card to fat16/fat32.

      The files are readable after editing them a little.
