This dongle is compatible with LinuxMCE, ControlThink and most other Z-Wave home control software. It uses the latest Z-Wave software, 4.27 from October 2008, with support for all the new command classes, and supports both high speed (4x 40kbps) and standard speed Z-Wave devices. What sets this USB interface apart is that it has a built in inclusion controller. You no longer need to have a separate master controller that you use to pair your Z-Wave modules, and then go through the process of replicating to transfer the data to your USB controller. Instead, just carry this USB dongle around as you turn on/off your Z-Wave modules and they are paired in one step. Available in either U.S. or Euro Z-Wave frequencies.
