I’m starting this topic here to document what I’m attempting to do with Node-RED as it pertains to a SKAARHOJ panel using Raw Panel messaging. I’ll be focussing specifically on the Waveboard panel. The panel has little displays as well as knobs, buttons, and faders, that I hope to use to control entities in HA.
Disclaimer: I don’t own one of these panels so I’m using the raw-panel-dummies emulator and the raw-panel-explorer to play around.
Here is a diagram of my dev environment. I’m working on integrating OSC with Home Assistant as well.
Here’s some of the docs and tools I’m using:
So far, I’ve been able to establish a TCP connection to the emulator and send/receive ASCII messages.
There’s two versions of ASCII messaging, V1 and V2. V1 uses simple text strings while V2 uses JSON strings. I couldn’t find in the documentation what termination was needed for sent messages, and, since received messages were terminated with CR, that’s what I was using. As it turns out, the string terminator chars need to be CRLF for sent messages. Also, the msg.payload needs to be a JSON string, not a JSON object. This threw me for a minute. Finally, it seems that no matter what ASCII version message is sent to the panel, the received messages are always ASCII V1.
How do I share the flow? Do I need to upload it to a file-sharing site and add a link here? Going to create Github repo and post my flows there.
Hey there, interesting Project, what is your end goal here ? 
Maybe I can make your life easier, as I did actually make a official HA integration, though it lacks a lot of love…
This would run directly on BluePill devices though, so not 100% the same.
Thanks. I’ll have a look. TBH, the original requestor has gone silent, so not sure if I’ll be working much on this or not.
OK cool, ping this thread if you are ever interested in expanding to that, I do a lot of funny homeassistant stuff and integrating with skaarhoj is straight forward in this case 
(I do work a lot for them)
