automation | Lutron Radio RA2 integration with DMX 512 light fixtures

Use the Lutron software to add a new dimmer, but don't pair it with any physical device. This is a virtual placeholder device that stands in for your DMX fixture.
Edit the "Zone Name" and append a ":" colon followed by the numeric DMX id of your fixture. See "site.json.sample" for more advanced DMX-related parameters.
Assign the dimmer to one of your keypad buttons just as what you would do with native Lutron devices.
Upload the new configuration to the Lutron controller and disregard the warning about the unassigned dimmer that you created.
Create a "site.json" file that has the username and password for your Lutron device, if you changed it from the default values.
Start the "automation" binary. Initializing the connection with the Lutron device can take up to about one minute.
Your DMX fixture should now operate just like any native Lutron output devices.
You can interact with your Lutron system by pointing your web browser to a local server running on port 8080. Wrap a reverse proxy around this server, if you need access control and/or SSL/TLS support.
Check "site.json.sample" for exmples of more advanced configuration options.
