 All the metrics you need are easily added in `DSMR_MAP` variable in `dsmr_map.h` file. With the DEBUG mode it's possible to see all the topics you add/create in the serial monitor. Also, it's possible to configure topic structure by changing `MQTT_ROOT_TOPIC` value in `settings.h` file.
 There is additional TEST mode to try your setup with test telegram and actual MQTT message send while your adapter is not connected to P1 port. 
 EMAIL_DEBUGGING is used to send debug messages to any email, e.g. GMail address. This is might be usefull to trace what's going on when device is connected to P1 port and actual debugging using USB port is impossible.
