Grizzly - Z-Wave Library for Elixir

Grizzly is a library for working with Z-Wave devices. Z-Wave is a low-frequency radio protocol for controlling smart home devices on a mesh network. Grizzly leverages Z-Wave over IP (Z/IP) to communicate to Z-Wave devices via DTLS. Grizzly provides complete support for the various Z-Wave security groups, extensible device behavior, and reliable error isolation between device behaviors.

Hardware requirements are:

  1. Z-Wave bridge controller
  2. zipgaway binary from Silicon Labs
  3. A Nerves system, custom or official.

To get up and running fast with a raspberry pi 3 check out the grizzly quickstart.

The zipgateway binary will need to be cross-compiled for your target. This can be a bit tricky, so if you need help with this part of the setup process please reach out on the forum by using the grizzly tag.

Z-Wave is a complex protocol with many moving parts and pitfalls. We hope that Grizzly provides a simple API for handling these complexities. As home automation and IoT grows in popularity we are excited to help the Elixir ecosystem provide reliable solutions to hard problems in this space.

If you have questions please feel free to reach out on the forum using the grizzly tag.

Special thanks to SmartRent for their support in open sourcing Grizzly!

Happy IoT hacking!


Yay! I can’t wait to try it out! Big thanks to @mattludwigs and the entire SmartRent team!

This is really really cool. I have been using Hypriot OS with elixir on docker containers to do home network stuff and was thinking about how to use z-wave with pi and elixir. I can’t wait to get this working.

By the way, if you want to get more people involved, I think you should announce Grizzly here: Some people there would love this project.


Thank you! If you run into any issues getting setup feel free to ask a question.

Thanks for the suggestion, I will look into announcing it there too soon!
