I have completed the install using the Virtualenv on a Raspberry Pi. I can access Home Assist on my local host. It picks up some Wemo light switches. I also have a Aeotec by Aeon Labs ZW090 Z Stick attached to the Raspberry Pi. I have a z-wave light switch I am trying to now get working. I have completed the PYTHON-OPENZWAVE instructions but they just end without any details on how I get the Z Stick configured. Here is what I have completed so far: https://home-assistant.io/getting-started/installation-virtualenv/
Follow the Configuration section at the bottom of this page:
Once you add the z-wave configuration to Home Assistant with the correct config_path, it should detect the stick and any paired devices (follow the instructions for your light switch and Z-stick to do the pairing).
