I’ve created a virtual device in Node-Red that’s supposed to write a random value to the virtual device AC-LOAD, but I can’t see it in the VRM?
Am I doing something wrong, or how do I make it visible in the VRM?
maybe you could copy something from my flow? it works for me

no idea how to post it here directly as graphical flow, but you could import it
