Running on UnRaid with USB support?

[christianwaite]

Hi, sorry if this is the wrong place for discussion.
I tried to create my own docker for OpenHAB2 a while ago, but being new to both Docker and OpenHAB I failed miserably (could get the interface to launch, but nothing else). Now I have OpenHAB running in a VM on UnRaid, but does your docker method work with a USB ZWave stick, i.e. it'll mount onto ttyUSB0 etc and can be used in HabMIN?

If so I might move back over to Docker instead of VM.
Thanks
Christian

Hello, also curious about this. How exactly does one pass a USB device on to a docker even?

You can use the --device parameter to map the host device into the container:

docker run --device /dev/usbACM0:/dev/usbACM0 ...

However, I still have some trouble with this in that after a stop/start or restart of the container OpenHAB keeps saying device /dev/usbACM0 not found although it is still possible to open the device in the container manually eg. using cat /dev/usbACM0. Any ideas what is wrong here?

I'm not using a USB ZWave stick, so can't troubleshoot. Have you tried kill/rm and create new container instead of restarting an existing one? Containers should be used in a stateless fashion. You can mount data volumes if you need to hang on to data.

Thanks for your suggestion, however that is what I'm doing right now but that is not an ideal situation. Following is shown in the log when I restart the container:

2015-11-30 20:45:44.965 [INFO ] [.z.internal.ZWaveActiveBinding:325 ]- Update config, port = /dev/ttyACM0

2015-11-30 20:45:44.987 [ERROR] [b.z.i.protocol.ZWaveController:342 ]- Serial Error: Port /dev/ttyACM0 does not exist

Strange thing is that I can open the device via the commandline and (binary) output is shown whenever ZWave-events are received from the USB-device. For now, having a workaround is fine with me. But it is cumbersome to have to remove the container only to recreate it again.

I have another issue that may or may not be related to sharing of the usb-device. From time to time the processing of zwave-events is sloppy and events are processed after a delay of 10s of seconds or not processed at all. The web-interface however, is always responsive on the desktop or via the app. Anyone experiencing similar issues?

We also experience the USB issue. I have tried everything in my mind.
I tried setting the -Dgnu.io.rxtx.SerialPorts parameter. Using symlinks and regular ttyUSB devices. Setting privileged: true.

Did someone resolve this issue?
