Zwave razberry2 rpi2 error

Configuration Z-Wave
21

Meanwhile I moved with my Raspberry to a different SD with the Raspbian image.
did the install and the update as well the RAZZBERRY update but still have the same issue

there is no /dev/ttyUSB…
pi@hassbian:~ $ ls /dev/ttyUSB*
ls: cannot access ‘/dev/ttyUSB*’: No such file or directory

But a AMA0

pi@hassbian:~ $ ls /dev/ttyA*
/dev/ttyAMA0

belong to group tty

pi@hassbian:~ $ ls -l /dev/ttyAMA0
crw--w---- 1 root tty 204, 64 Dec 14 20:59 /dev/ttyAMA0

I added:

zwave:
  usb_path: /dev/ttyAMA0

to my virgin configuration.yaml

HomeAssistant is still throwing and error at startup:

2017-12-14 20:59:52 ERROR (MainThread) [homeassistant.setup] Error during setup of component zwave
Traceback (most recent call last):
  File "/srv/homeassistant/lib/python3.5/site-packages/openzwave/option.py", line 75, in __init__
    raise ZWaveException(u"Can't write to device %s : %s" % (device, traceback.format_exception(*sys.exc_info())))
openzwave.object.ZWaveException: "Zwave Generic Exception : Can't write to device /dev/ttyAMA0 : ['NoneType: None\\n']"

But now the group is tty and there is

pi@hassbian:~ $ ls -l /dev/ttyAMA0
crw--w---- 1 root tty 204, 64 Dec 14 20:59 /dev/ttyAMA0
pi@hassbian:~ $ grep 'tty' /etc/group
tty:x:5:

and I asume to run it as homeassistant

pi@hassbian:~ $ ps axu | egrep "homeassist|hass"

run sudo raspi-config. Pick “Interfacing Options”, then “Serial”. Answer “No”, then “Yes” to the questions. Reboot. Add your homeassistant user to the dialout group: usermod -aG dialout homeassistant. (Assuming “homeassistant” is the user that Home Assistant runs as).

Greate thanks. I installed the Razberry binary they told me in the documentation. and I figured out that it also did what you are saying. Everything working like a charm.
