No data from SML Smartmeter to nodered

Hello everbody,

I would be really happy, if someone could help me with my 'smartmeter problem'.

Mosquitto, nodered, timescaledb and grafana are running on a raspberry pi 4 as docker containers. With mqtt messages everything works fine. But I fail to get data from a smartmeter (sml) into nodered. The raspi is connected to an optical sensor via usb cable and I get data on the raspi (sudo cat /dev/ttyUSB0 | od -tx1).

At the momemt I am using the 'node-red-contrib-smartmeter' node, but I do not find any parameter configuration to get any data into nodered. Below you see the 2 nodes nodered flow as well as the properties of the smartmeter node (connection details: 9600 Baud rate, 8N1 - should be fine since it is from the manual and already worked before).

Does someone have an idea? Is there an alternative for the smartmeter node that should work?

Thank you very much in advance!
