Sorry to dredge up an old topic, but I’m having major issues with z-wave :frowning:

I can open up the OZWCP fine, and it finds my device etc,

but then as soon as I add the lines

  usb_path: /dev/ttyACM0 

to my config.yaml file, I lose the front end. If I comment them out, the frontend comes back.

Anyone have any ideas? This is driving me insane!

I’ve tried with a fresh install of hassbian, fresh AiO install, everything else sets up fine, but as soon as I try and add zwave, I lose the front end.

home-assistant.log does not contain any errors at all.
