Serial Error: Port /dev/ttyAMA0 does not exist

Setup, Configuration and Use Beginners

Hi,
This problem is much written (Raspberry+Z-wave.me).
Solution:

  1. The correct permissions.
  2. Extra java opts: -Dgnu.io.rxtx.SerialPorts=/dev/ttyAMA0

I was not able to solve the problem. I do not think it is right to point 2 (extra java opts).
The latest version but the other folder structure, and I am not an expert in Java.

Please help me. Where is the embed code? Please with example code, I need to see the whole syntax.

Sorry for my bad english.

You say you have correct permissions but not what you did. Did you add the openhab user to the dailout group?

If you are running Jessie on a RPi, check if the ‘getty’ is on the serial device.

sudo systemctl status serial-getty@ttyAMA0.service;
and maybe try with stopping it:
sudo systemctl stop serial-getty@ttyAMA0.service;

In “raspi-config” serial console has to be enabled.

Added
dialout:x:20:pi,openhab

serial-getty@ttyAMA0.service - stopped. But “Port /dev/ttyAMA0 does not exist”

Are using GPIO-pin or USB?
What does ls /dev/tty* show?

Using GPIO-pin (http://raspberry.z-wave.me).
