Trying to control older lighting system over RS-232 with simple ASCII commands?

Eric,

This is 98% of what your want, already done for you. Just change the RS-232 commands to match your old lighting system and you’ll be there. I did not write it, but I helped the guy who did with getting started on the Arduino/ThingShield code. He made the Arduino code very simple - just a passthrough device between ST and the RS-232 shield. Note: You’ll want to use an Arduino MEGA 2560 along with my “SmartThings” ThingShield library (which is needed to support the extra HW UARTs on the MEGA 2560 for serial comms.)

Lutron RadioRA Integration

My house came with two different lighting systems, about 40 Decora style stand-alone Lutron dimmers, and a Lutron RadioRA lighting system for the main living areas. The stand-alone dimmers were all replaced with Leviton Z-Wave dimmers, and incorporated in SmartThings. The issue remained of what to do with the Lutron RadioRA system. I have created an integration of Lutron RadioRA into SmartThings. The integration is based on an Arduino Mega 2560 with ThingShield and RS232 shield connected via serial cable to a Lutron RadioRA RA-RS232 interface. One very cool thing about the integration is that all of the hardware connects via RF – there is no wiring involved. The integration is clean and does not interfere at all with the normal functioning of the Lutron system. If it is removed, or …
