Configuring Aeotec Zwave stick

I had a homeassistant install working on RPI3 but it crashed. No recent backup, but I have some stuff. But I can’t get my Zwave stick to work. This is on 72.1 on raspian.

File “/srv/homeassistant/lib/python3.5/site-packages/homeassistant/setup.py”, line 143, in _async_setup_component hass, processed_config) File “/srv/homeassistant/lib/python3.5/site-packages/homeassistant/components/zwave/init.py”, line 245, in async_setup config_path=config[DOMAIN].get(CONF_CONFIG_PATH)) File “/srv/homeassistant/lib/python3.5/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/ttyUSB0 : [‘Traceback (most recent call last):\n’, ’ File “/srv/homeassistant/lib/python3.5/site-packages/openzwave/option.py”, line 75, in init\n raise ZWaveException(u"Can\‘t write to device %s : %s" % (device, traceback.format_exception(*sys.exc_info())))\n’, ‘openzwave.object.ZWaveException: “Zwave Generic Exception : Can\'t write to device /dev/ttyUSB0 : [\‘NoneType: None\\\\n\’]”\n’]’

did you set it to /dev/ttyACM0 in your zwave config? I don’t think I’ve seen one get set to USB0

also make sure the user running HA has permission/privileges to write to the Z stick. That’s what the last line of the error is complaining about. If the name is correct ie. /dev/ttyUSB0, then it may just be a permission issue. The user has to be in the group dialout.

see here.
