Bluetooth seems to work fine but Xiaomi BLE devices does show up

Configuration
1

Hi all!

I’m trying to setup a new instance of home assistant on my Raspberry Pi 4. I would like to integrate a Xiaomi H&T BLE ( LYWSD03MMC ) using the built-in bluetooth adapter.

I installed Home Assistant using Docker, this is the docker-compose.yml:

version: '3'
services:
  home-assistant:
    container_name: home-assistant
    image: homeassistant/home-assistant:2022.11.1
    volumes:
      - ./${PROJECT_DATAS_FOLDER}/home-assistant/config:/config
      - /etc/localtime:/etc/localtime:ro
      - /run/dbus:/run/dbus:ro
    restart: unless-stopped
    privileged: true
    networks:
      network1:
        ipv4_address: ${NETWORK1_SUBNET}.78
    dns:
      - ${NETWORK1_SUBNET}.${NETWORK1_DNSIP}
    devices:
     - /dev/serial1:/dev/serial1
    labels:
      - "traefik.enable=true"
      # .. other traefik labels

As shown by the docker-compose I am using Home Assistant version 2022.11.1 and I’d prefer not using the network mode host.

As shown by the following screenshot, I am able to see the adapter in the integration page. However I cannot see the Xiaomi BLE device I want to integrate.

The Xiaomi BLE device is up and running, I can see it even from Windows and from my phone.

Additional information:

My host system has installed bluez-5.65-3.

Linux kernel:

$ uname -a
Linux raspberry 5.15.74-2-MANJARO-ARM-RPI #1 SMP PREEMPT Thu Oct 20 16:43:17 UTC 2022 aarch64 GNU/Linux

I also tried to scan bluetooth devices using bluetoothctl from the host and from the docker, here the results:

# scan from the host
[pi@raspberry services]$ bluetoothctl scan on
Discovery started
[CHG] Controller E4:5F:01:**:**:** Discovering: yes
[NEW] Device A4:C1:38:**:**:** LYWSD03MMC

# open a shell inside the docker
[pi@raspberry services]$ docker exec -it home-assistant /bin/bash
# scan from the docker
bash-5.1# bluetoothctl scan on
Discovery started
[CHG] Controller E4:5F:01:**:**:** Discovering: yes
[CHG] Device A4:C1:38:**:**:** RSSI: -54

In “settings → system → logs” I found this ERROR message:

What am I doing wrong?

Apparently I was missing to add a device in the devices list in the docker-compose.yml:

$ ls -la /dev/serial1 
lrwxrwxrwx 1 root root 7 Oct 21 02:57 /dev/serial1 -> ttyAMA0

Adjusting this fixed the issue:

    devices:
     - /dev/serial1:/dev/serial1
     - /dev/ttyAMA0:/dev/ttyAMA0

Now I am able to see the Xiaomi BLE in the device list, it seems to be not working properly but that’s a different kettle of fish.
