Accept license:
/cnf?cmd=accept_license&acc=1&allow_usage_stats=a
a = 1 allow reporting of usage stats to cFos eMobililty, a = 0 disallow

Change admin password:
/cnf?cmd=change_admin_pwd&old_pwd=old&new_pwd=new
old, new are the old and new admin password

Delete a device:
/cnf?cmd=del_device&dev_id=d
d is a valid device ID

Get a unique user ID (for creation of a new user):
/cnf?cmd=get_new_user_id
returns a new user ID as a JSON string

Reset a device:
/cnf?cmd=reset_device&dev_id=d
d is a valid device ID. The device will be destroyed and re-created

Start stop diagnose logging:
/cnf?cmd=set_diag_logging&enable=e
e = 1 to start, e = 0 to stop diagnose logging. Runs for 5 minutes if not stopped
