lxc config device add hass Z-Wave unix-char path=/dev/ttyACM0
If you have multiple devices that may end up at that path, you should
instead use something like:
lxc config device add hass Z-Wave unix-char
source=/dev/serial/by-id/usb-FTDI_FT232R_USB_UART_A60337Y1-if00-port0
path=/dev/ttyACM0
This will ensure that the device at /dev/ttyACM0 in the container is always the
same one.
I do this in my openhab container here where I have the following devices:
usb-alarm:
gid: "111"
path: /dev/ttyUSB1
source: /dev/serial/by-id/usb-FTDI_FT230X_Basic_UART_DQ00AXEP-if00-port0
type: unix-char
uid: "0"
usb-insteon:
gid: "111"
path: /dev/ttyUSB0
source: /dev/serial/by-id/usb-FTDI_FT232R_USB_UART_A60337Y1-if00-port0
type: unix-char
uid: "0"
usb-z-wave:
gid: "111"
path: /dev/ttyACM0
source: /dev/serial/by-id/usb-0658_0200-if00
type: unix-char
uid: "0"
