The Zwave frequency used in the USA (908.4MHz) is used for mobile phone spectrum in Australia. Zwave needs to be 919.8 MHz or 921.4 MHz in Australia to be legal. Currently the z-wave in the Pro only supports US z-wave protocol.
Please U-TEC provide support for this. Any Aussies out there wanting this also, please put in a vote here! oi-oi-oi!
