Adding HA z-wave to existing z-wave network?

I have a Samsung hub up and running with some Z-Wave devices.
I also have a RPi - HA running as well covering some different areas. I have a working Z-Wave stick in the RPi and the OpenWave all working.

Can I (should I) add the Z-Wave RPi to the existing network, and if so how? I would like the visibility that the HA gives. I don’t want to crash my existing network!
