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

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
