小米门窗传感器接入Home Assistant 无需小米网关 （CC2531方案）

首先你得装好Zigbee2mqtt这个软件，并且cc2531参考前面的教程正常识别并且启动。

自制ZigBee网关教程参考下面链接：

小米门窗传感器配对教程参考下面视频：

Home Assistant 配置方法如下：

增加一个MQTT二进制传感器，类型为门。

binary_sensor:
  - platform: mqtt
    name: 大门
    state_topic: "zigbee2mqtt/0x00158d000460188a"  #替换你自己设备ID，并删掉这句注释。
    value_template: "{{ value_json.contact }}"
    payload_on: false
    payload_off: true
    availability_topic: "zigbee2mqtt/bridge/state"
    payload_available: "online"
    payload_not_available: "offline"
    qos: 0
    device_class: door

增加两个MQTT普通传感器，类型分别位电量和信号强度。

sensor:
  - platform: mqtt
    name: 门磁电量
    state_topic: "zigbee2mqtt/0x00158d000460188a"  #替换你自己设备ID，并删掉这句注释。
    value_template: "{{ value_json.battery }}"
    unit_of_measurement: "%"
    availability_topic: "zigbee2mqtt/bridge/state"
    payload_available: "online"
    payload_not_available: "offline"
    qos: 0
    device_class: battery 

  - platform: mqtt
    name: 门磁信号强度
    state_topic: "zigbee2mqtt/0x00158d000460188a"  #替换你自己设备ID，并删掉这句注释。
    value_template: "{{ value_json.linkquality }}"
    availability_topic: "zigbee2mqtt/bridge/state"
    payload_available: "online"
    payload_not_available: "offline"    
    qos: 0
    device_class: signal_strength
