How to reset Data log to start, but keep setting?

Is there a simple way of resetting the logged data pool, but keep all the setting of the CTs and names etc?.

AFAIK there are at least two possibilities:

  1. Delete the history and current data log via IoTaWatt-API: Graphs no longer working - #6 by overeasy
  2. Or download the config.txt file, insert the SD-card into your computer, remove all content and copy the SD files from the github site onto it and also your saved copy of the config file.

I would recommend #1 above.

Just went into 2 blank chrome pages and typed each one of these commands and looks like that it has restarted my data log a fresh.
When entering each page command i get a OK response back
