Retrieving data from an old SD card with previous emon OS

Hi @TrystanLea.

Thanks for your message. I have been trying out the various ways of importing backup data this morning (detailed Doing a 'Full Update' to the emonPi caused it to 'brick' - #3 by SteffanCook).

What I really wanted though was a way to turn those .DAT files (in the backups) into readable CSV data. I don’t want to use the graphical interface module on emonCMS to pull out the data, I want to get the data from the backup. THe graphical interface is a bit cumbersome (I could kill those calendar UI) and it tends to be limited to a few thousand data sets, and I have tens of thousand size data sets to get out so that means many attempts.

Any straightforward way to decode those .DAT files available?

Cheers. Diolch
