[SOLVED] Does not exist /dev/ttyAMA0

[Eddiie (Eddie Eddie)]

Hi,
I have been trying to get OH1.8 working with my RaspberryPi and Razberry.
Zway worked when it was installed from a previous attempt.

• ls /dev shows /dev/ttyAMA0

• This is the second clean install I’ve attempted using the apt-get method.

• Addon installed - sudo apt-get install openhab-addon-binding-zwave

• I’ve sudo usermod -a -G dialout openhab ; rebooted

The log at start up is simple… The device does not exist. It does.

What am I doing wrong?

This is a very common question - the answer is normally related to the permissions that the user has and whether or not they can access the ports…

Unablel to make Zwave USB Stick work (ZME_UZB1)

Hi everybody, after 2 days of playing around with my raspberry pi and openhab I received the Zwave USB stick. Unfortunately I am not able to make that one work. Openhab ist installed, habmin and the iPhone App. So far the dry runs where working. Now to the problem with the stick. The stick shows up in the lsusb as Device 13 pi@raspberrypi:/opt $ lsusb Bus 001 Device 013: ID 0658:0200 Sigma Designs, Inc. Bus 001 Device 003: ID 0424:ec00 Standard Microsystems Corp. SMSC9512/9514 Fast Ethernet …

There are suggestions to start openhab as root using start.sh but start.sh does not exist when using the apt-get install method.

[Eddiie (Eddie Eddie)]

There was another suggestion to edit line 5 of /etc/default/openhab .
The comments in that file say if there is no parameter on line 5, then they system will use root:root
this is not the case, it still runs as openhab
Modifying line 5 to be root:root will not launch openhab

Thanks for the help.

This is the Startup script I use in my Ubuntu Server. I think it should also work for the Raspberry.

Take a look at the DAEMON_ARGS on line 56 and see how it sets the USB port of my zwave device?

FIXED!!!

ls -l /dev/ttyAMA0 shows

pi@raspberrypi:/etc/default $ sudo ls -l /dev/ttyAMA0
crw–w---- 1 root tty 204, 64 Jan 19 19:38 /dev/ttyAMA0

It says “tty” group, so I modified the command to grant openhab to tty instead of dialout

sudo usermod -a -G tty openhab

Now I am out of diskspace using 4GB SD card and Raspian Jessie Full Desktop.
At least I am past this hurdle!!!
