To give a name (not unknown) to a Leviton Z-wave power receptacle I had to add this line:
<Product type="1d04" id="0334" name="DZR15-1LZ Binary Scene Switch"/>
To the leviton section of this file:
manufacturer_specific.xml
In two directories:
/srv/homeassistant/lib/python3.4/site-packages/libopenzwave-0.3.3-py3.4-linux-armv7l.egg/config
/srv/homeassistant/src/python-openzwave/openzwave/config
My starting point for the Z-wave installation was Hassbian 1.1.
I am not happy about the duplication of several Z-wave files in this installation. Maybe this is solved in the new hassbian-config tool?
