Ray CLI

Ray CLI is a command-line engineering utility for generating and broadcasting DMX data over sACN and Art-Net.

Installation

Install ray-cli from PyPi:

# With pip.
pip install ray-cli

# With pipx.
pipx install ray-cli

# Or uv.
uv tool install ray-cli

Or, directly from GitHub:

Note: The GitHub installation requires uv to be installed!

Usage

Basic Example

To broadcast a ramp DMX signal to a specific IP address:

ray-cli sacn            \
    --dst 192.168.86.67 \
    --mode chase        \
    --universes 1 2     \
    --channels 24       \
    --fps 50            \
    --duration 60
