I have a light control board that uses a Main board to send lighting signals to a Receiver board via ethernet cable. I'm trying to allow that to happen wirelessly, by putting 2 RPi's in between each board to send the signal via tcp.
I connected to my Pi (pi1) to the Main board via ethernet jack. I want to take the signal it's sending to my pi1, and wirelessly share it to another Pi (pi2) on my network. Then it would be sent to another board via pi2 ethernet.
I can send/receive via TCP from pi1 to pi2. So that's a start...
I'm not sure how to tell pi1 how to look for the message on it's ethernet port... As in, when it gets a message from my lighting controller, how do I "find" that message in node-red so that I can then send to pi2??
Similarly, how do I tell the data received wirelessly on pi2, and have it send it out via it's ethernet port to the receiver??
The board I'm using is PixLite 16 MkII Pixel Controller seen here... https://www.advateklights.com/pixlite-control/
