As a continuation of my Open Smart Hub project I have been interested in adding Z-Wave and Zigbee devices to my supported devices and recently decided to swing for Z-Wave devices first. I bought a Z-Wave Z-Stick Series 2 USB Dongle from Aeon Labs and a simple Z-Wave Door Sensor in order to create the basic mesh network with just two devices.
Since the Open Smart Hub is based in NodeJS, it only made sense to search for a Node port of the OpenZwave library. I stumbled upon Jonathan Perkin’s port of it to NodeJS (https://github.com/jperkin/node-openzwave)
Unfortunately, it does not work on Windows, and it seems to be having issues with the latest version of NodeJS… But luckily (or coincidentally) the Open Smart Hub runs on a Raspberry Pi 2 running Raspbian and NodeJS v0.10.28.
After the initial setup of my RPi2 with NodeJS, I got to work getting the node-openzwave module on my RPi2. I was seeing build errors when it was trying to install the module, but found a couple of blogs with information that in order to get it to work I might have to install a couple more tools.
sudo apt-get install build-essential make subversion
sudo apt-get install subversion libudev-dev make build-essential git-core python2.7 pkg-config libssl-dev
After that, it worked and I could call “npm install openzwave” and have it install properly.
Note: If you are interested in using it on Mac OSX, you will need to install the drivers for it. Read more about that process in a previous blog post.
