Home Assistant has its own basic ZWave configuration UI, but sometimes you just want OZWCP. I ran into this desire recently, and after getting sick of swapping my controller between my laptop and my Hass.io box, I built an OZWCP plugin for Hass.io.
The main caveat here is that OZWCP and Home Assistant’s ZWave support can’t both be running at the same time. The plugin will stop Home Assistant before starting OZWCP, but it’s up to you to stop OZWCP before starting Home Assistant again.
