Zwave disappeared, how to add it back

I have been using it for years now, since 1 or 2 vbersions it disappeared

It always was

zwave:

usb_path: /dev/ttyACM0

or
usb_path: /dev/serial/by-id/usb-0658_0200-xxx

but now both do not work

In my hardware info I have under serial

/dev/ttyS0
/dev/ttyS1
/dev/ttyS2
/dev/ttyS3
/dev/ttyS4

but which one is it, or do I have to go by luck and restart HASSIO 1 to 4 times to get it right? Tried S0 and S1, but its not, at least its not populated after adding, or for each try do I have to wait some times to see if it populates???

Where you see this?

In /dev path of OS you should see zwave stick.
If all you had was what listed above maybe it not connected.

Have you tried unplug and replug zwave stick or reboot OS?

I am using HASSIO, in hardware info, rebooted OS, yes.

Now I am trying as you say, took out the stick re inserted, and restarted OS

Forgot that was there

Yeah, look like zwave stick is missing. You do still have Integration added?

Removal reinsert of the stick did it
