Each region has its own Z-Wave frequency. In Arduino IDE you can choose the frequency for your region in the menu. Note that radiofrequency of your Z-Uno allows to use nearby frequencies. There are free types of Z-Uno: 868 MHz, 908/916 MHz and 928 MHz. All frequencies fits in one of these three types. Currently only those frequencies are supported:
  • Europe
  • Russia
  • China
  • India
  • USA *
  • Hong Kong *
  • Israel *
  • Brazil *
  • Australia and New Zealand *
* — Z-Uno hardware for these frequencies is not yet available. Using existing EU version of hardware with these frequencies will result in a very short range (about 1-2 meters).
