That was the issue. I corrected that.
Current problem: Do I need to reconnect the official add-on to get a device listing per this community guide, or can I open a file in .storage or elsewhere to copy these out?
Here is the issue:
I should get the result as shown in this image, but I am not, so I am thinking I need to restart the official add-on (with UI add-on stopped; and note, I never finished creating a new Integration for the UI add-on).
In the integration, I check the box for using the Z-Wave JS Supervisor add-on. One observation is I have to check this box each time I try. I would think it should remember.
Another observation is if I never created a second Integration for the UI add-on per the instructions, why is its check-box not checked already?
On the next window, the USB device path radio button is on and showing ttyACM0 - /dev/serial/by-id/usb-0658_0200-if00, s/n: n/a - 0658:0200
This matches what I see in Hardware as well as the ZwaveJS add on. And the ZwaveJS add-on log shows communication with devices, no errors.
If there is another way to get the listing of devices, I can ignore all of this and proceed with the UI add-on, then proceed with the clean install. Please advise.
