Hi all,  
I need you help making SmartMeter work with my nodered ...

**System**

1. Weidmann Elektronik IR IR Schreib/Lesekopf USB (Optokopf) - Infrarot Sendediode (Tx), Infrarot Phototransistor (Rx) IC: FTDI FT232R / FT230X USB-to-UART Serial Converter

2. USB adapter found on /dev/ttyUSB1

_lsusb_  
Bus 002 Device 016: ID 0403:6015 Future Technology Devices International, Ltd Bridge(I2C/SPI/UART/FIFO)

1. NodeRed v3.0.2 on a docker on ubuntu  
using portainer I added to the start of the docker "privileged mode" and the device /dev/ttyUSB1

**Test**

1. tested with Weidmann Elektronik Emolog tool end got data with 300 7E1 bidirectional
2. tested with minicom -b 300 -D /dev/ttyUSB1 and got data which looks a little bit strange but I believe it is data

**Node-RED**

1. Installed node-red-contrib-smartmeter
2. created new flow with smarmeter node
3. configured node

But in the debug window I always get

_smartmeter-obis error: Error: Error on Baudrate changeover: Error: Port is not open_

Any hint or help is highly appreciated

Thanks
