Bluetooth integration

Requirements

Bluetooth integration的正常运行，有以下要求:

硬件

树莓派硬件 蓝牙芯片 版本

软件

操作系统内核

与蓝牙相关的软件版本

The D-Bus socket must be accessible to Home Assistant.
The Bluetooth adapter must be accessible to D-Bus and running BlueZ >= 5.43. It is highly recommended to use BlueZ >= 5.63 as older versions have been reported to be unreliable.
The D-Bus implementation should be dbus-broker.
The host system should be running Linux kernel 5.15.62 or later.

Bluetooth integration通过D-bus和BlueZ进行通信。

ha version Requirements

Bluetooth Requirements for Linux systems

For Bluetooth to function on Linux systems:

The D-Bus socket must be accessible to Home Assistant.
The Bluetooth adapter must be accessible to D-Bus and running BlueZ >= 5.43. It is highly recommended to use BlueZ >= 5.63 as older versions have been reported to be unreliable.
The D-Bus implementation should be dbus-broker.
The host system should be running Linux kernel 5.15.62 or later.

ADDITIONAL REQUIREMENTS BY INSTALL METHOD
Home Assistant Operating System: Upgrade to Home Assistant OS version 9.0 or later.
Home Assistant Container: The host system must run BlueZ, and the D-Bus socket must be accessible to Home Assistant inside the container.
Home Assistant Supervised: The host system must run BlueZ, and the D-Bus socket must be accessible to Home Assistant inside the container.
Home Assistant Core: The system must run BlueZ, and the D-Bus socket must be accessible to Home Assistant.

Add bluetooth integration

output

No unconfigured Bluetooth adapters found. There are 0 ignored adapters.

添加bluetooth集成后，如果周围有支持的蓝牙设备，ha就会自动发现、并提醒你配置.
有的设备点一下提交就完事儿了，比如小米的花花草草传感器；
稍微复杂一点的，按提示输入密钥等参数即可，比如小米的蓝牙温湿度计。

没有发现蓝牙设备的原因只有两个：不支持、收不到信号（不在通信范围没电没开等）

然后你应该，在集成界面，点击添加集成，搜索xiaomi ble，点击，应该就能发现蓝牙设备了。
ps：针对小米的蓝牙设备
