Obviously I'm no expert, but from the research that I've done, beaming is another protocol on top of the mesh network. Beaming allows a z-wave device to pass on encrypted packets through the mesh network. If there isn't a continuous path of beaming capable devices between the z-wave controller and the lock, it will not work. I know others have gotten these locks to work with other controllers, notably the Vera.
The one lock that does work does take about 1 second to actuate and another 8 seconds to report back.
