SmartThings Lutron RadioRa Integration
There are three Device Types that you need to install in the IDE - Lutron Shield, Lutron RA Switch, Lutron RA Dimmer.
These need to be in your "My Device Handlers", published.
Edit the device type of your ThingShield device to be Lutron Shield.
There is the Arduino sketch, that installs on Arduino Mega 2560.
There is the Lutron Gateway SmartApp, that you install in the IDE.
The required hardware consists of - Lutron RadioRA RA-RS232, Arduino Mega 2560, with, SmartThings ThingShield, and Arduino RS232 shield.
The Arduino RS232 shield connects to the RA-RS232 with null modem cable. There must be jumpers from pins 2,3,4,5 to pins 14,15,16,17 on the Mega.
