Thanks!
I added
config_path: /srv/homeassistant/src/python-openzwave/openzwave/config
and now there are no errors in the home-assistant.log
I used that path based on the info in this thread, but I’m not sure it’s the right solution in this case. Cannot open Control Panel (ozwcp) Cannot find a path to the configuration files
I don’t have any zwave devices, yet, but I’m guessing that no errors means it’s setup correctly now and once I get that “Cannot open Control Panel (ozwcp)” from the thread above solved I can take the next step of deciding which motion sensor to buy 
The closest folder I have to your example is
/srv/homeassistant/lib/python3.4/site-packages/libopenzwave-0.4.0.31-py3.4.egg-info
but it doesn’t contain anything named config. In that aforementioned thread I mentioned which folders and links do exist if that helps.
