 // IMPORTANT: Parameters defined in config.h are only default values, and are applied if:
 //   * the ampel is flashed for the first time
 //   * or 'reset_config' command is called
 //   * or AMPEL_CONFIG_VERSION has been changed.
-
 // Once those default values have been applied, uploading the firmware with a modified config.h will not update the ampel configuration!
 // Every parameter can be modified and saved later via the web-config.
 // Some of those parameters can also be modified via commands in the Serial monitor :
 //    e.g. 'wifi 0' to turn WiFi off, or 'csv 60' to log data in csv every minute.
