Hi，I use UDP in node, and i already set the global port , like this:
and here is my question, how to get the global QT_VHL_PORT for UDP_IN node port setting?
By the way, for udp out node , get the global QT_VHL_PORT is easy to set, no problem.
This is not supported. You can use an environment variable though. See: Using environment variables : Node-RED
Thanks for reply , your suggestion of environment variable is exactly what i want.
