DPT 232.600 from KNX bus not recieved

[MDAR]

Salutation (I'll not respond to users that doesn’t wrote at least "Hello")
That's an excellent statement, I think for the sake of humanity, that should be an absolute minimum. 😄

👋 Hello to you sir.

Describe the bug
As I'm very new to KNX and your Palette, I'm not sure if this is a bug or my own lack of knowledge.

(My experience is of Velbus building control, ARTnet/sACN/DMX, Node-RED basic configuration)

Situation is:-
I have supplied a Pixel pattern generator to an installer in order to run a large quantity of addressable LED tape.
This application can be controlled by various methods, one of which is fairly simple DMX over ARTnet.

I supplied a Node-RED instance on the same machine as a fail safe if we struggled to get any kind of remote control working.

The installer has opted for KNX as the backbone to the building so I was delighted to find your Palette.

Very quickly, we achieved

• Switching - 1.001 or 1.002
• Dimming - 5.001 or 5.004
• Scene setting - 5.005 or 17.001

The final step is to accept RGB values from KNX and push them into the pixel software

We found 232.600, which the installer insists he is sending into the KNX bus.

The KNXViewer node outputs the array from the address, but it presents as a DPT 11.001 (date time value).
The RAW data is the correct hex value for the colour he is sending.

The KNXDevice node doesn't output anything at all, regardless of what DTP we select.

Is there a way to just output whatever is received / sent to an address, so I can find the RGB value in it somewhere or I am just not configuring the KNXDevice node correctly?

Knx-Ultimate Version

• 4.1.9

Are you running node-red behind homematic, docker or anything similar?

• Node-Red V4.1 running on Odroid C4, NOT in a container. Everything else is working as expected.
• QLCplus on same machine, with separate LAN connection for outgoing sACN Pixel data

Additional context

Debug data from the KNXviewer node.

Hi
Have you seen the documentation? KNX can be easy and can be challenging.
In your case, if you must send RGB Datapoint "232.600 RGB color triplet", that's pretty simple. I assume that there should be a KNX device, transforming the payload into a suitable DMX command.
The Group Address must be written with "/", not with "." For example 3/0/0 instead of 3.0.0
If you click "Details" near to the datapoint, you'll see how to build the payload. Copy/Paste the flow below.

PS: Are you sure that the Group Address 17/0/10 is correct? Please ask ChatGPT or Gemini to briefly tell you how KNX work, so you can have a better view and you can integrate KNX into artNet/DMX or whatever you need to control your light.

Thanks for your amazing speed of response.

The error was the formatting of the address.

17/0/10 and the data started flowing in.
