Sending a node red payload from one Venus GX to another?

Hello,

Would it be possible to send a node red payload from one Venus GX (Venus OS Large) to another, using just the Victron back-end for networking, if the IP addressing and security could be solved?
I would like to send solar forecast once or twice daily to 2-3 Venus GX installs on the same offgrid island. Maybe using web sockets or similar, could it be done, would it be allowed?
What would the smartest way to achieve this be?

Many thanks for any helpful comments.

Hello.

Just a quick note from me, not sure if it is helpful. I did experiment with this briefly half a year ago, attempting to send information from a running node-red instance on a laptop to the one on my Raspberry Pi. I remember I did succeed using the "tcp in" and "tcp out" -nodes. Unfortunately I disregarded that project quickly so I don't remember exactly how I did it more than those nodes are what I used...

Hope you get it working,

MrHappy

Hi,

You could Use the Mqtt broker of both Venus devices and a node red flow reading one topic from one broker and writing one the other one.
