Installing zwave

Hi,

I am new to the forum and new to Home Assistant.
I have purchased the Aeotec Z-Stick Gen 5. I am running Hass.io version 1.13 on a Raspberry pi 3 Model B but I cannot get it to work.

the hassio hw info command gives the following snippet …
{
“result”: “ok”,
“data”: {
“serial”: [
“/dev/ttyAMA0”,
“/dev/ttyACM0”

I have added the following to the configuration.yaml file (Note that I have tried both ACM0 and AMA0)

Z-Waves

zwave:
usb_path: /dev/ttyACM0

The OZW log file says …

An ls command of /dev gives the following
core-ssh:/dev# ls

full mqueue ptmx random stderr stdout urandom

There is no /dev/ttyACM0 or /dev/ttyAMA0.

Is that the issue causing the DriverFailed?

Any help appreciated. I am new at this.

Thanks.
