See also: http://wiki.volkszaehler.org/software/controller/vzlogger


Changes in the new version:

=== Meter configuration ===

There is a new parameter:
        "enabled" : true,       /* disabled meters will be ignored */

=== Channel configuration ===

There are several new parameters:

  * When using volkszaehler as middleware you need:

        "protocol" : "vz", /* volkszaehler.org */


  * When using mysmartgrid as middleware you need:

       "protocol" : "mysmartgrid",
       "device"    : "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx",
       "uuid" :      "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx",
       "secretKey" : "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx",
       "interval" : 300, /* */
       "identifier" : "1-0:1.8.0",
       //"scaler" : 1,  /* sml counter is in Wh */
       "scaler" : 1000,  /* d0 counter is in kWh */


where the values for device, uuid, and secretKey are created by using the uuidgen command.



The values for device and secretKey will be the same for each channel.
  
  
Before starting the vzlogger, the logger must be registrated by running:
     vzlogger -r
     
  
On mysmartgrid.de you have to connect to the logger of your mysmartgrid account. There for you on the page 'Geräte' and use the first 10 character (without '-') of the configured device-uuid.
