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

Simply Brilliant!
I originally had a Arduino with a ethernet daughter board attached to a couple of Home plugs to enable communication out to the garage. This enabled me to control some out door mains powered lights. This little device has made the process so much simpler, I no longer require the Arduino, ethernet daughter board or Home plug sockets, this has replaced them all! And when you add up the cost of all I had, this is so much cheaper too! Thanks and Vesternet!
