  1.    This Z-Uno Board for Arduino - Gen5
  2. RaZberry PI GPIO Daughter Card - Gen5

Z-Uno is the first and only easy to use developer board that allows you to create your own Z-Wave device without deep knowledge of Z-Wave protocol or programming. Z-Uno is a mix of Z-Wave home automation radio protocol power and Arduino simplicity. Being inspired by Arduino project Z-Uno inherits all concepts of easy-to-use hardware and software solutions, keeping maximum flexibility.

Z-Uno is a fully DIY product. It is made for those who are limited by existing choice of Z-Wave products and wants to extend their smart homes with more sensors and actuators: connect LEDs, buttons, switches, motors or any low voltage sensor including most of Arduino compatible sensors.

Z-Uno programming is done by writing sketch in simplified C language and loaded into Z-Uno using Arduino IDE. Many examples and comprehensive tutorials will help you to make your own project.

Being Z-Wave Plus certified device, Z-Uno is the perfect companion for you RaZberry gateway. Z-Uno is compatible with other controllers too: among them Fibaro Home Center 2, Fibaro Home CenterLite, Vera Edge and Zipato Zipabox.


Make your own Z-Wave device:

  • Control any Arduino compatible peripherals
  • Define your own logic by modifying your sketch
  • Use Arduino IDE and language to write and upload sketches
  • Easy to use
  • Requires no knowledge of Z-Wave protocol
  • Complete DIY solution


Z-Wave Plus

The Z-Uno Board for Arduino is Z-Wave Plus Certified. Z-Wave Plus (5th Generation Z-Wave) offers a lot of new features including increased range, extended battery life and Over The Air upgrading (OTA). Take a look at our "What is Z-Wave Plus" guide for more information
