Zwave Errors

Configuration
1

I have been having so many problems with adding Zwave devices and not much luck, only a couple devices I have been able to add. I was going to try the openzwave beta, but I decided not to. I had added the integration but removed it not long after. Things were working fine after I removed the integration but I just added a networkkey in options file, rebooted and now having this issue, trying removing network key and rebooting and still having this issue.

Check that your device is still /dev/ttyACM0 and that it’s available to HA. You may have to reboot your host after removing the add-on.

Is there a way I can check through HA itself? I am using Nabucasa as my setup is at my cottage and I won’t be returning for a couple weeks.

It was working fine until I changed the networkkey in options.xml. I reverted my changes back but no luck.

EDIT - I changed the USB path from ending in a 0 to a 1 and now it works. - Thanks.

Thanks.
