I just purchased this as part of a kit. Setup is fairly straightforward between this Remote and the Conversion module. Pairing this device with the Wireless Gateway is another story.
Once I paired the Scene Controller (WDHA-12) with my Home Controller (Vera), I was easily able to set the secondary buttons to control two scenes. Now I can operate the garage door, a few lamps in my house, and run the "All Off" scene from about 200 ft away. Me likes.
