Hass.io z-wave Aeotec stick 5gen not working

Hi everyone,

here is my first message to the forum, and unfortunately it is a cry for help…

I set up a raspberry pi 3 with hass.io , so far I’ve been able to play with some of the components (especially MQTT) and it seems to be working, except for Z-wave.

I have an Aeotec Stick 5gen into an USB port of the pi, I installed the SSH component and I can see the device using the ssh command

"serial": [

So I changed the configuration.yaml

  usb_path: /dev/ttyACM0

When I restart the PI, I get this error in the log

Log Details (ERROR)

Error setting up entry Z-Wave (import from configuration.yaml) for zwave
Traceback (most recent call last):
  File "/usr/local/lib/python3.6/site-packages/openzwave/option.py", line 78, in __init__

openzwave.object.ZWaveException: "Zwave Generic Exception : Can't find device /zwaveusbstick : ['NoneType: None\\n']"

During handling of the above exception, another exception occurred:

Now, I’m not sure where to put my hands here, the serial device is visible and it is the one I put in the configuration file, so after a restart it should work.

Any ideas ?

Thank you all in advance

Raspberry PI 3B+
Hass.io 0.83.2

Ok, I’ll reply to myself.

I made a test with a new install, and it now seems to be working.

The initial tests are two-three weeks old, so nothing is certain here, but I may have understood the mistake.

I activatated the zwave component and then I moved to other installs, which means I rebooted a couple of times.

Reading ( more carefully :blush: ) the hass.io pages regarding z-wave it says that the first time the component is installed it can take 30 minutes on a pi;
I guess the reboots during this process aren’t considered best practice :slight_smile:

Ok, so everything seems to be working now, so back to work.

Cheers everyone
