How to create new devices for z-wave

Hi, I developed new zwave device by my own and increase the number of nodes i.e 9 endpoints but on openhab I want to test. So I am confused how to get all nodes on openhab with this also showing electric meter value. Please guide me what should be the next so I can make gateway on openhab. My work is pending because of this only my firmware is ready for test.

Any idea?
