Do anyone have a clue on how to help a fresh smart home / HA-user?
Was expecting the learning curve to be steep - but have gotten to a problem I simply don’t see a way out of. My serach around the internet and this forum gives me different problems I’m not completely able to relate to mine.

I’m running Home Assistant under VMware ESXi. Installed from the image available on home-assistant.io/hassio/installation/.

I have inserted the Aeotec Z-wave stick into the back port of my Intel NUC. (Also have an RFXtrx inserted - but not a priority to get this to work at this moment.)

I have tried several times to get the Z-wave installed and working.

First time I added it to the configuration.yaml with the code:

zwave:
  usb_path: /dev/ttyACM0

And this resulted in this log entry in HA:

Logger: homeassistant.config_entries
First occured: 15:55:09 (1 occurences)
Last logged: 15:55:09

Error setting up entry Z-Wave for zwave

Traceback (most recent call last):
  File "/usr/local/lib/python3.7/site-packages/openzwave/option.py", line 78, in __init__
    raise ZWaveException(u"Can't find device %s : %s" % (device, traceback.format_exception(*sys.exc_info())))
openzwave.object.ZWaveException: "Zwave Generic Exception : Can't find device /dev/ttyAMA0 : ['NoneType: None\\n']"

During handling of the above exception, another exception occurred:

  File "/usr/src/homeassistant/homeassistant/components/zwave/__init__.py", line 369, in async_setup_entry
    config_path=config.get(CONF_CONFIG_PATH),
  File "/usr/local/lib/python3.7/site-packages/openzwave/option.py", line 81, in __init__
    raise ZWaveException(u"Error when retrieving device %s : %s" % (device, traceback.format_exception(*sys.exc_info())))
openzwave.object.ZWaveException: 'Zwave Generic Exception : Error when retrieving device /dev/ttyAMA0 : [\'Traceback (most recent call last):\\n\', \'  File "/usr/local/lib/python3.7/site-packages/openzwave/option.py", line 78, in __init__\\n    raise ZWaveException(u"Can\\\'t find device %s : %s" % (device, traceback.format_exception(*sys.exc_info())))\\n\', \'openzwave.object.ZWaveException: "Zwave Generic Exception : Can\\\'t find device /dev/ttyAMA0 : [\\\'NoneType: None\\\\\\\\n\\\']"\\n\']'

I have no idea on where it gets “/dev/ttyAMA0” from as I have not entered that anywhere.

So I deleted Z-wave from HA / integrations and from configuration.yaml .

Restarted. Added it again from HA / Integrations and typed in /dev/ttyACM0 as the USB address.
HA then automatically added this to configuration.yaml :

zwave:
  usb_path: /dev/ttyAMA0

And it gives this error

Again I have no idea where HA gets ttyAMA0 from …

Some terminal output:

In advance thanks for any help given :slight_smile:
