  • Add Lutron RadioRA commands to your M1 system

Essential Info

Now you can use your M1 system to communicate with your Lutron RadioRA lighting controls. This interface gives you the full functionality of RadioRA, such as controlling lights, shades, and thermostats. With the features built into M1, you can now control RadioRA from across the room or around the world. This module is a type 5 serial expander; the M1 architecture is limited to a total of seven of this type of device.

In order to integrate RadioRA into the M1 universe, the following parts are required:
  • 1x - M1 system
  • 1x - M1-to-Lutron RadioRA Serial Interface (this product)
  • 1x - Elk RP Remote Programming Software
  • 1x - Lutron RadioRA2 Main Repeater
  • 1x - Lutron PC Essentials setup and configuration software This is an absolute REQUIREMENT for third party integration. It is NOT possible to integrate with a Lutron RadioRA2 system unless it was setup and programmed with the PC Essentials software! This is restriction imposed by Lutron, not Elk.

  • More Info

    M1XSLU vs. M1XSP Serial Expander: The unique hardware and software configuration of the M1XSLU enables nearly plug-and-play integration with RadioRA2, without the need for special jumper settings or firmware. Elk also produces a standard M1XSP serial interface but it cannot be loaded with the special firmware needed to support RadioRA2. Some customers have found it possible to use the M1XSP in its generic ASCII Text String mode to send basic 1-way integration commands to Lutron RadioRA2. This basic method of interfacing cannot obtain status, track lighting status changes, or support RadioRA2 Thermostats. The M1XSLU is the only method for obtaining true integration with RadioRA2.
