Many Arduinos on serial ports with node-red (raspberry pi 4)

Hi there,
have several Ardinos in different places and would like e.g. temp values ​​on node-red to each
created serial interfaces (/dev/ttyUSB0). How should I configure the serial interfaces in node-red.

Kind regards
Max

How have you configured the Arduindo's serial interfaces? The Node-RED settings should match.
