When the configuration file is not preset, E1 normally creates a new one with the default configuration. Uploading a backup should work too. This is the default configuration:
setup.cfg (702 Bytes)
It must be placed in /ctrlv2/ directory on the sdcard.
If needed this is the full “image” of the sd card:
sd.zip (1.9 MB)
After making changes to the configuration or sd card contents outside of the app.electra.one, you may need to force reload the Controller page in the web browser to see them.
