Cannot find the port for z-wave controller

Setup, Configuration and Use Runtime

Hi,

I setup a docker based on CentOS and have openhab-online-2.0.0.b4 in it (The dockerfile is similar to GitHub - openhab/openhab-docker: Repository for building Docker containers for openHAB). It’s running and I can add binding Astro binding and Z wave binding and add things for Astro. But when I try to add my Zeon Labs Aeotec z wave stick, Gen 5, I saw the error “port /dev/ttyACM0” doesn’t exist (see blow)

07:11:44.565 [INFO ] [smarthome.event.ThingAddedEvent ] - Thing ‘zwave:serial_zstick:7dbcfbf2’ has been added.
07:11:44.596 [INFO ] [me.event.ThingStatusInfoChangedEvent] - ‘zwave:serial_zstick:7dbcfbf2’ changed from UNINITIALIZED to INITIALIZING

07:11:44.614 [INFO ] [me.event.ThingStatusInfoChangedEvent] - ‘zwave:serial_zstick:7dbcfbf2’ changed from OFFLINE (BRIDGE_OFFLINE): Controller is offline to OFFLINE (COMMUNICATION_ERROR): Serial Error: Port /dev/ttyACM0 does not exist

I log in to the docker image, to verify that the file /dev/ttyACM0 exist

$ ls -l /dev/ttyACM0
crw-rw---- 1 root uucp2 166, 0 Oct 17 20:35 /dev/ttyACM0

And user openhab is in the group uucp2 too.

Also on the host system, I verify that /dev/ttyACM0 also exists

$ ls -l /dev/ttyACM0
crw-rw---- 1 root uucp 166, 0 Oct 18 07:21 /dev/ttyACM0

The user starts docker image is in the group uucp

The way I start the image is

docker run
–name openhab
–net=host
-v /etc/localtime:/etc/localtime:ro
-v /etc/timezone:/etc/timezone:ro
-v $volumeDirectory/conf:/openhab/conf
-v $volumeDirectory/userdata:/openhab/userdata
–device=/dev/ttyACM0
-d
–restart=always
-P openhab

Right now I have no idea why it still cannot find the port. If I get the docker image from GitHub - openhab/openhab-docker: Repository for building Docker containers for openHAB, it seems to work. Can anybody help me to diagnose?

It’s permission issue, though I have added openhab to group uucp2. When I run openhab as root (by removing creating user and setting user from dockerfile and rebuilt), z-wave controller becomes online.

I don’t really know docker but i had to add this to /etc/default/openhab as java argument:

-Dgnu.io.rxtx.SerialPorts=/dev/ttyAMA0

I don’t find the file /etc/default/openhabin the docker image. I don’t even installed it from the package manager. I download the zip file and unzip it.

But I tried to:

  1. add that option to runtime/karaf/bin/karaf
    as option to start karaf executable
    or 2, the environment variable EXTRA_JAVA_OPTS, which becomes options to start karaf executable

There’s no luck.

5

have you tried adding the user openhab to the dialout group?

6

Ah. No. But why does it need to be in dialout? The group of /dev/ttyACM0 is uucp2.

Sorry. I double check. Yes. openhab is already in dialout group and it doesn’t work.
