Bluetooth on LXC - docker - Home Assistant (Turnkey template)

[caxaciim]

Hi!

I have nonprivileged LXC (Turnkey template) and I am running Home Assistant (and others) in docker. I have Conbee and RFLink running ok AND bluetooth is visible in LXC and inside HA container. But. Home Assistant does not see bluetooth.

I have tried external (Asus BT-500) also. No luck.

root@homeassistant /opt# lsusb
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 002: ID 8087:0a2a Intel Corp. Bluetooth wireless interface
Bus 001 Device 008: ID 0b05:190e ASUSTek Computer, Inc.
Bus 001 Device 006: ID 1cf1:0030 Dresden Elektronik ZigBee gateway [ConBee II]
Bus 001 Device 007: ID 2341:0042 Arduino SA Mega 2560 R3 (CDC ACM)
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

docker-compose.yaml:

    volumes:
      - /opt/homeassistant:/config
      - /etc/localtime:/etc/localtime:ro
      - /run/dbus:/run/dbus:ro

Now I am lost and I would appreciate greatly if anybody can give at least some advice what to check/do next.

Thank you.

bluetooth as usb are both busses and they cannot be passthroughed. You can only passthrough a device, so that is also true for bluetooth. If you have a bluetooth serial device, you can e.g. have that in your docker

I am a bit confused. People are using bluetooth on Docker installations and the HomeAssistant OS itself is running ok on VirtualBox and it sees laptop's BT. How are those installations working?

I am wondering if I need to compile just right version of the BlueZ and install BT-500 drivers - but I am not sure where (Proxmox itself, LXC or inside Docker container...)

Can you explain a bit more, thank you.

VirtualBox is the same as QEMU/KVM. You will not have problem if you just abandon LX(C) containers and switch to a "real" VM.
