node-red-contrib-udmx
A node for outputting DMX through a USB dongle
This node looks for a UDMX dongle with USB ID 16c0:05dc and allows a single DMX channel to be set to a value.
It works with the Chinese usb to DMX adapters readily available (e.g. search ebay for "usb dmx").
Installation
Use the 'Manage Palette' option from the Node-Red admin panel, then search from the 'Install' tab.
If not found, you can install manually:
In your .node-red folder run:
npm i node-red-contrib-udmx
then restart the node-red service.
Usage
Set msg.topic to the DMX channel (1-512) and msg.payload to the value (0-255).
Tips
- Restart node-red after inserting dongle to ensure it is detected
