Google Home脚本编辑器中湿度触发脚本报错求助

我需要实现当车间传感器1的相对湿度（RH%）大于车间传感器2时，开启车间进气扇，但编写的脚本持续报错，无法正常运行。

原脚本代码 #

metadata:
  name: Intake Fan On/Off
  description: Intake fan to be on only when sensor 1 RH% is greater than sensor 2 RH%

  starters:
    - type: device.state.HumiditySetting # For devices that support humidity settings such as humidifiers and dehumidifiers.
      device: Workshop Sensor 1 - Workshop
      state: humiditySetpointPercent
      greaterThan:
        [
          ('device.Workshop Sensor 2 - Workshop') 'state.humiditySetpointPercent',
        ]

  actions:
    - type: device.command.OnOff # Turn the device on or off.
      # Whether to turn the device on or off.
      on: true
      devices: Intake Fan - Workshop

收到的错误信息 #

The value should be one of [String, Bool, Number, Temperature, ColorTemperature, DateTime, Time, Weekday, Duration, ColorHex] but is [Array] instead. The expected formats for time string are [HH:MM:SS; HH:MM; HH:MM AM/PM; HH AM/PM; sunrise/sunset]. The expected formats for duration string are [HHhMMm; HHhMMmSSs; HHhoursMMminSSsec; HHhrsMMminutesSSseconds; MMminutes; HHh MMm]. The expected formats for weekday string are [monday; TUESDAY; WED; fri].

错误原因及修正方案 #

核心错误点 #

1. 状态类型误用：device.state.HumiditySetting是给加湿器/除湿器这类设备的设定湿度用的，而传感器的实时湿度应该用device.state.Humidity
2. 比较值格式错误：greaterThan字段不能用数组格式，引用其他设备状态需要使用标准的device+state嵌套语法

修改后的正确脚本 #

metadata:
  name: Intake Fan On/Off
  description: Intake fan activates when Workshop Sensor 1 humidity > Workshop Sensor 2 humidity

starters:
  - type: device.state.Humidity
    device: Workshop Sensor 1 - Workshop
    state: ambientHumidityPercent
    greaterThan:
      device: Workshop Sensor 2 - Workshop
      state: ambientHumidityPercent

actions:
  - type: device.command.OnOff
    on: true
    devices: Intake Fan - Workshop

可选补充：添加风扇关闭逻辑 #

如果需要当传感器1湿度回落至等于/小于传感器2时自动关闭风扇，可以扩展脚本如下：

metadata:
  name: Intake Fan On/Off
  description: Intake fan activates/deactivates based on humidity difference between two sensors

starters:
  # 开启风扇条件
  - type: device.state.Humidity
    device: Workshop Sensor 1 - Workshop
    state: ambientHumidityPercent
    greaterThan:
      device: Workshop Sensor 2 - Workshop
      state: ambientHumidityPercent
  # 关闭风扇条件
  - type: device.state.Humidity
    device: Workshop Sensor 1 - Workshop
    state: ambientHumidityPercent
    lessThanOrEqualTo:
      device: Workshop Sensor 2 - Workshop
      state: ambientHumidityPercent

actions:
  # 根据触发条件自动切换开关状态
  - type: device.command.OnOff
    devices: Intake Fan - Workshop
