Hello,

I am really new to proxmox....

I create a LXC for Deconz with your script.
But after assign a passthrough Device (/dev/serial/by-id/usb-dresden_elektronik_ConBee_III_DE0xxxxxx-if00-port0)
I got the error during start... starts failed

safe_mount: 1425 No such file or directory - Failed to mount "/dev/ttyUSB1" onto "/usr/lib/x86_64-linux-gnu/lxc/rootfs/dev/ttyUSB1"
safe_mount: 1425 No such file or directory - Failed to mount "/dev/ttyACM0" onto "/usr/lib/x86_64-linux-gnu/lxc/rootfs/dev/ttyACM0"
safe_mount: 1425 No such file or directory - Failed to mount "/dev/ttyACM1" onto "/usr/lib/x86_64-linux-gnu/lxc/rootfs/dev/ttyACM1"
run_buffer: 571 Script exited with status 17
lxc_setup: 3948 Failed to run autodev hooks
do_start: 1273 Failed to setup container "101"
sync_wait: 34 An error occurred in another process (expected sequence number 4)
__lxc_start: 2114 Failed to spawn container "101"
TASK ERROR: startup for container '101' failed

I do not know what ist the problem... the Device is visible at the host....

Any Idea ?

How do you have passthrough the device? Like our zigbee howto in #410?

So its defintily not an Script issue. Next time use Discussions as QA

I add the it as a "device passthrough" via GUI. I do not know any config file where I could put the direct device path in deconz as in the z2m config file.

So how I have passthrough the USB Device to the deconz container ?

(Next Time I will use the discussion area, sorry)

Try this:

Get the device name:
ls -l /dev/serial/by-id/
Set assign the device to deconz in:
/etc/systemd/system/multi-user.target.wants/deconz.service

2.1 Set the Device:
Testcase:
ExecStart=/usr/bin/deCONZ -platform minimal --http-port=80 --dev=/dev/ttyACM1

Why "/dev/ttyACM1" ? The device is at /dev/ttyUSB0 ...

I tried different variants... but at the moment the conbee 3 nocht recogniced....but I think there may be an other reason...my lenovo under the proxmox have no "usb 2" port...and actually I find no old usb 2 hub...so I will return the next day if I connected only with USB 2.

Thank you

regards

I found the problem...in the deconz.service file I put the specific device AND the bautrate

ExecStart=/usr/bin/deCONZ -platform minimal --http-port=80 --dev=/dev/serial/by-id/usb-dresden_elektronik_ConBee_III_DE0xxxx02-if00-port0 --baudrate=115200

Without the baudrate the conbee III will not be recognized.
