从 mqtt 配置二进制传感器

Question

我有启用了 MQTT 客户端的 zway 控制器和将状态发布到 mqtt 主题的二进制传感器。

zway95/data/ZWayVDev_zway_9-0-48-12

{
  "creationTime": 1587157138,
  "creatorId": 1,
  "customIcons": {},
  "deviceType": "sensorBinary",
  "firmware": "3.80",
  "h": 1979762458,

    "probeTitle": "Motion",
    "scaleTitle": "",

    "level": "off",

    "isFailed": false
  },
  "nodeId": 9,

  "visibility": true,
  "updateTime": 1643685077
}

zway95/state/ZWayVDev_zway_9-0-48-12

off

或

on

我HA也有这样的配置

binary_sensor:
  - platform: mqtt
    state_topic: "zway95/state/ZWayVDev_zway_9-0-48-12"
    name: "testmotion"
    device_class: "motion"
    payload_on: "true"
    payload_off: "false"
    availability_template: "{{ value_json.metrics.isFailed }}"
    availability:
      - topic: "zway95/data/ZWayVDev_zway_9-0-48-12"
    payload_available: false
    payload_not_available: true
    json_attributes_topic: "zway95/data/ZWayVDev_zway_9-0-48-12"

在 HA 中，传感器看起来不可用并且缺少属性

我哪里弄错了？

Answer 1

这是工作配置：

binary_sensor:
  - platform: mqtt
    state_topic: "zway95/state/ZWayVDev_zway_9-0-48-12"
    name: "testmotion"
    device_class: "motion"
    payload_on: "on"
    payload_off: "off"
    availability_topic: "zway95/data/ZWayVDev_zway_9-0-48-12"
    availability_template: "{{ value_json.metrics.isFailed }}"
    payload_available: false
    payload_not_available: true
    json_attributes_topic: "zway95/data/ZWayVDev_zway_9-0-48-12"

Answer 2

我的理解是home assistant documentation availability_template 是为了和availability_topic一起使用。所以要么去

availability_template: "{{ value_json['metrics']['isFailed'] }}"
availability_topic: "zway95/data/ZWayVDev_zway_9-0-48-12"
payload_available: false
payload_not_available: true

或

 availability:
   - topic: "zway95/data/ZWayVDev_zway_9-0-48-12"
     payload_available: false
     payload_not_available: true
     value_template: "{{ value_json['metrics']['isFailed'] }}"

从 mqtt 配置二进制传感器

configure binary sensor from mqtt
