Smartmeter2mqtt socket output
You can have this application expose several sockets. It will start a tcp socket at the specific port that will emit data as it comes in.
JSON socket
If you enable the JSON socket you have access to a socket that emits parsed dsmr messages as they come in. The json messages are delimited by \r\n so you can expect a complete json message per line.

Raw socket
If you enable the raw socket, you will have access to the DSMR messages as they come in. You can use this if you want to connect other applications to the one connection you have with the smartmeter. This can also be used in combination with decrypting, that means you can have this app decrypt the data from some smartmeters and forward it unencrypted to an other application.
