For those interested, the topic is moving from his first subject, here is the drawing from the pi connector to zwave module adaptor.

I connected it to the pi connector of a raspberry pi b+ without the two resistors and the inductor and it works really well under domoticz see screenshots below (in a french version of domoticz):

So you have just to "take" another GND on the pi b+ gpio connector.
Hope this helps!
