Automation API 支援

自動化 API 支援下列溫度控制器特徵和元素。

取得環境溫度

使用溫度控制器取得環境溫度

如要使用 Thermostat 特徵取得溫度控制器的環境溫度,請讀取 localTemperature 屬性。

// Get the ambient temperature
val thermostat = home.devices().list().first { device -> device.has(Thermostat) }

val thermostatTraitFlow: Flow<Thermostat?> =
  thermostat
    .type(ThermostatDevice)
    .mapNotNull { it.standardTraits.thermostat }
    .distinctUntilChanged()

val localTempFlow = thermostatTraitFlow.mapNotNull { it?.localTemperature }
val automation = automation {
  sequential {
    val starterNode = starter<_>(thermostat, ThermostatDevice, Thermostat)

    // If the temperature is higher than 35C...
    condition { expression = starterNode.localTemperature greaterThan 35 }

    // ...and the automation hasn't been run for at least an hour...
    suppressFor(Duration.ofHours(1))

    // ...broadcast a message
    action(speaker, SpeakerDevice) {
      command(AssistantBroadcast.broadcast("It's very hot outside."))
    }
  }
}

使用 TemperatureMeasurement 取得環境溫度

如要使用 TemperatureMeasurement 特徵取得溫度控制器的環境溫度,請讀取 measuredValue 屬性。

val temperatureTraitFlow: Flow<TemperatureMeasurement?> =
  thermostat
    .type(TemperatureSensorDevice)
    .map { it.standardTraits.temperatureMeasurement }
    .distinctUntilChanged()

val localTemp: Short? = temperatureTraitFlow.first()?.measuredValue
val automation = automation {
  sequential {
    val temperature = starter<_>(thermostat, ThermostatDevice, TemperatureMeasurement)
    val stateReaderNode = stateReader<_>(light, DimmableLightDevice, OnOff)
    condition() {
      val expr1 = temperature.measuredValue greaterThanOrEquals 35
      val expr2 = stateReaderNode.onOff equals true
      expression = expr1 and expr2
    }
    action(light, DimmableLightDevice) { command(OnOff.on()) }
  }
}

使用 ExtendedThermostat 取得平均溫度

如要取得多個感應器的平均溫度,請讀取 ExtendedThermostat 特徵的 averageLocalTemperature 屬性。

// Get the average temperature
val thermostat = home.devices().list().first { device -> device.has(TemperatureSensorDevice) }

val temperatureTraitFlow: Flow<TemperatureMeasurement?> =
  thermostat
    .type(TemperatureSensorDevice)
    .map { it.standardTraits.temperatureMeasurement }
    .distinctUntilChanged()

val localTemp: Short? = temperatureTraitFlow.first()?.measuredValue
val automation = automation {
  sequential {
    val temperature = starter<_>(thermostat, ThermostatDevice, ExtendedThermostat)
    val stateReaderNode = stateReader<_>(light, DimmableLightDevice, OnOff)
    //  if the average temperature is >= 35C
    condition() {
      val expr1 = temperature.averageLocalTemperature greaterThanOrEquals 35
      val expr2 = stateReaderNode.onOff equals true
      expression = expr1 and expr2
    }
    // Turn on the light
    action(light, DimmableLightDevice) { command(OnOff.on()) }
  }
}

取得環境濕度

如要使用 RelativeHumidityMeasurement 特徵取得溫度控制器的環境濕度,請讀取 measuredValue 屬性。

// Get the ambient humidity

val humidityTraitFlow: Flow<RelativeHumidityMeasurement?> =
  humiditySensingThermostat
    .type(HumiditySensorDevice)
    .map { it.standardTraits.relativeHumidityMeasurement }
    .distinctUntilChanged()

val localHumidity: UShort? = humidityTraitFlow.first()?.measuredValue
val automation = automation {
  sequential {
    val humidity = starter<_>(thermostat, HumiditySensorDevice, RelativeHumidityMeasurement)
    val stateReaderNode = stateReader<_>(light, DimmableLightDevice, OnOff)
    // if the ambient humidity is >= 80%
    condition() {
      val expr1 = (humidity.measuredValue greaterThanOrEquals 80u)
      val expr2 = (stateReaderNode.onOff equals true)
      expression = expr1 and expr2
    }
    // Turn on the light
    action(light, DimmableLightDevice) { command(OnOff.on()) }
  }
}

選取要顯示的溫度刻度

如要變更溫度控制器顯示的溫度測量單位,請將 ThermostatUserInterfaceConfigurationTraittemperatureDisplayMode 屬性設為 TemperatureDisplayModeEnum.CelsiusTemperatureDisplayModeEnum.Fahrenheit

// Set the displayed temperature scale to Fahrenheit
val uiConfig =
  home
    .devices()
    .list()
    .filter { device -> device.has(ThermostatUserInterfaceConfiguration) }
    .first()

val uiConfigTraitFlow: Flow<ThermostatUserInterfaceConfiguration?> =
  uiConfig
    .type(ThermostatDevice)
    .map { it.standardTraits.thermostatUserInterfaceConfiguration }
    .distinctUntilChanged()

val uiConfigTrait: ThermostatUserInterfaceConfiguration = uiConfigTraitFlow.first()!!

if (
  uiConfigTrait.supports(ThermostatUserInterfaceConfiguration.Attribute.temperatureDisplayMode)
) {
  val unused =
    uiConfigTrait.update { setTemperatureDisplayMode(TemperatureDisplayModeEnum.Fahrenheit) }
}
val automation = automation {
  isActive = true
  sequential {
    val stateReaderNode =
      stateReader<_>(thermostat, ThermostatDevice, ThermostatUserInterfaceConfiguration)

    // When someone says "Show the temperature in Fahrenheit",
    val unused =
      starter<_>(structure, VoiceStarter.OkGoogleEvent) {
        parameter(VoiceStarter.OkGoogleEvent.query("Show the temperature in Fahrenheit"))
      }
    // if the temperature isn't being shown in Fahrenheit
    condition() {
      expression =
        stateReaderNode.temperatureDisplayMode notEquals TemperatureDisplayModeEnum.Fahrenheit
    }
    // display the current temperature using Fahrenheit
    action(thermostat, ThermostatDevice) {
      update(ThermostatUserInterfaceConfiguration) {
        setTemperatureDisplayMode(TemperatureDisplayModeEnum.Fahrenheit)
      }
    }
  }
}

變更操作模式

只要設定 ThermostatTrait.Attributes.systemMode 屬性 (其值由 ThermostatTrait.Attributes.SystemModeEnum 定義),即可將溫度控制器限制為特定的運作模式,這些模式由 ThermostatTrait.SystemModeEnum 定義。

val thermostatDevice = structure.devices().list().first { device -> device.has(Thermostat) }

val thermostatTraitFlow: Flow<Thermostat?> =
  thermostat.type(ThermostatDevice).map { it.standardTraits.thermostat }.distinctUntilChanged()

val thermostatTrait: Thermostat = thermostatTraitFlow.first()!!

// Set the system mode to Auto
if (thermostatTrait.supports(Thermostat.Attribute.systemMode)) {
  val unused = thermostatTrait.update { setSystemMode(SystemModeEnum.Auto) }
}
val automation = automation {
  isActive = true
  // When the door lock state changes
  sequential {
    val doorLockEvent = starter<_>(doorLock, DoorLockDevice, LockOperationEvent)
    val stateReaderNode = stateReader<_>(thermostat, ThermostatDevice, SimplifiedThermostat)

    // if the door is unlocked and the thermostat is in Eco mode
    condition() {
      val expr1 = (doorLockEvent.lockOperationType equals LockOperationTypeEnum.Unlock)
      val expr2 = (stateReaderNode.systemMode equals SimplifiedThermostatSystemModeEnum.Eco)
      expression = expr1 and expr2
    }

    // Set the thermostat to Auto mode
    action(thermostat, ThermostatDevice) {
      command(SimplifiedThermostat.setSystemMode(SimplifiedThermostatSystemModeEnum.Auto))
    }
  }
}

溫度控制器設定為 SystemModeEnum.Auto 時,系統可從 ThermostatTrait.Attributes.thermostatRunningMode 讀取溫度控制器執行模式的其他資訊,該資訊會填入 ThermostatRunningModeEnum 的值。

// Get the current thermostat running mode

val runningModeTraitFlow: Flow<Thermostat?> =
  thermostat.type(ThermostatDevice).map { it.standardTraits.thermostat }.distinctUntilChanged()

val runningMode: ThermostatTrait.ThermostatRunningModeEnum? =
  runningModeTraitFlow.first()?.thermostatRunningMode
val automation = automation {
  isActive = true
  sequential {
    val stateReaderNode = stateReader<_>(thermostat, ThermostatDevice, Thermostat)
    // at 10:00am
    val unused =
      starter<_>(structure, Time.ScheduledTimeEvent) {
        parameter(Time.ScheduledTimeEvent.clockTime(LocalTime.of(10, 0, 0, 0)))
      }

    // if the thermostat is in Auto mode and is currently cooling
    condition() {
      val expr1 = (stateReaderNode.systemMode equals ThermostatTrait.SystemModeEnum.Auto)
      val expr2 =
        (stateReaderNode.thermostatRunningMode equals
          ThermostatTrait.ThermostatRunningModeEnum.Cool)
      expression = expr1 and expr2
    }
    // announce that it's in Cool mode
    action(structure) {
      command(AssistantBroadcast.broadcast("The thermostat is currently running in Cool mode."))
    }
  }
}

SimplifiedThermostatTrait 旨在簡化自動化動作中設定運作模式的程序。如要使用 SimplifiedThermostatTrait 變更溫度控制器的運作模式,請使用 SetSystemModeCommand,其值由 SimplifiedThermostatTrait.SystemModeEnum 定義。

這個特徵僅可搭配 Automation API 使用。

Automation API
val automation = automation {
  isActive = true

  sequential {
    // When the presence state changes...
    val starterNode = starter<_>(structure, AreaPresenceState)
    // ...and if the area is unoccupied...
    condition() {
      expression = starterNode.presenceState equals PresenceState.PresenceStateVacant
    }
    // Set the thermostat to Eco mode
    action(thermostat, ThermostatDevice) {
      command(SimplifiedThermostat.setSystemMode(SimplifiedThermostatSystemModeEnum.Eco))
    }
  }
}

如要判斷溫度控制器可運作的系統模式,請讀取 ThermostatTrait.Attributes.controlSequenceOfOperation,其值由 ThermostatTrait.ControlSequenceOfOperationEnum 決定。

// Get the controlSequenceOfOperation
val standardTraitFlow: Flow<Thermostat?> =
  thermostat.type(ThermostatDevice).map { it.standardTraits.thermostat }.distinctUntilChanged()

val controlSequenceOfOperation: ThermostatTrait.ControlSequenceOfOperationEnum? =
  standardTraitFlow.first()?.controlSequenceOfOperation
val automation = automation {
  isActive = true
  sequential {
    val stateReaderNode = stateReader<_>(thermostat, ThermostatDevice, Thermostat)
    // When someone says "Switch to cool mode",
    val unused =
      starter<_>(structure, VoiceStarter.OkGoogleEvent) {
        parameter(VoiceStarter.OkGoogleEvent.query("Switch to cool mode"))
      }
    // if the thermostat is capable of operating in Cool mode,
    condition() {
      val expr1 =
        stateReaderNode.controlSequenceOfOperation notEquals
          ControlSequenceOfOperationEnum.HeatingOnly
      val expr2 =
        stateReaderNode.controlSequenceOfOperation notEquals
          ControlSequenceOfOperationEnum.HeatingWithReheat
      expression = expr1 and expr2
    }

    action(thermostat, ThermostatDevice) {
      // switch to Cool mode
      update(SimplifiedThermostat) {
        command(SimplifiedThermostat.setSystemMode(SimplifiedThermostatSystemModeEnum.Cool))
      }
    }
  }
}

變更編程操作模式

您可以使用 ThermostatthermostatProgrammingOperationMode 變更溫度控制器的編程操作模式,其值由 ProgrammingOperationModeBitmap 定義。

val thermostatTraitFlow: Flow<Thermostat?> =
  thermostat.type(ThermostatDevice).map { it.standardTraits.thermostat }.distinctUntilChanged()

val thermostatTrait: Thermostat = thermostatTraitFlow.first()!!

if (thermostatTrait.supports(Thermostat.Attribute.thermostatProgrammingOperationMode)) {
  val programmingOperationMode = thermostatTrait.thermostatProgrammingOperationMode!!

  // Enable autoRecovery on the thermostatProgrammingOperationMode
  val unused =
    thermostatTrait.update {
      setThermostatProgrammingOperationMode(
        ThermostatTrait.ProgrammingOperationModeBitmap(
          programmingOperationMode.scheduleActive,
          true,
          programmingOperationMode.economy,
        )
      )
    }
}
// When someone says "Reset programming operation mode"
val automation = automation {
  isActive = true
  sequential {
    val unused =
      starter<_>(structure, VoiceStarter.OkGoogleEvent) {
        parameter(VoiceStarter.OkGoogleEvent.query("Reset programming operation mode"))
      }
    // Set all the flags on the programming operation mode
    action(thermostat, ThermostatDevice) {
      update(Thermostat) {
        setThermostatProgrammingOperationMode(ProgrammingOperationModeBitmap(true, true, true))
      }
    }
  }
}

變更溫度設定點

如要使用 Thermostat 變更溫度設定點,請呼叫 ThermostatTrait.SetpointRaiseLowerCommand

val thermostatTraitFlow: Flow<Thermostat?> =
  thermostat.type(ThermostatDevice).map { it.standardTraits.thermostat }.distinctUntilChanged()

val thermostatTrait: Thermostat = thermostatTraitFlow.first()!!

// lower the temperature setpoint by 1 degree C
thermostatTrait.setpointRaiseLower(amount = 1, mode = SetpointRaiseLowerModeEnum.Cool)
val automation = automation {
  isActive = true
  sequential {
    val stateReaderNode = stateReader<_>(thermostat, ThermostatDevice, Thermostat)
    // At 10:00pm
    val unused =
      starter<_>(structure, Time.ScheduledTimeEvent) {
        parameter(Time.ScheduledTimeEvent.clockTime(LocalTime.of(22, 0, 0, 0)))
      }
    // if the setpoint is warmer than 19C
    condition() { expression = stateReaderNode.occupiedCoolingSetpoint greaterThan 19 }

    // lower the temperature setpoint by 5 degrees
    action(thermostat, ThermostatDevice) {
      command(Thermostat.setpointRaiseLower(SetpointRaiseLowerModeEnum.Cool, 5))
    }
  }
}

將溫度設定點設為優先值

如要讓溫度設定點優先於預先設定的時間表,請將 ThermostatTraittemperatureSetpointHold 屬性設為 TemperatureSetpointHoldEnum.SetpointHoldOn,或是將時間表設為 TemperatureSetpointHoldEnum.SetpointHoldOff,讓時間表優先。

val thermostatTraitFlow: Flow<Thermostat?> =
  thermostat.type(ThermostatDevice).map { it.standardTraits.thermostat }.distinctUntilChanged()

val thermostatTrait: Thermostat = thermostatTraitFlow.first()!!

if (thermostatTrait.supports(Thermostat.Attribute.temperatureSetpointHold)) {
  // Set temperatureSetpointHold to SetpointHoldOn
  // allowing temperature setpoints to override any preprogrammed schedules.

  val unused =
    thermostatTrait.update {
      setTemperatureSetpointHold(TemperatureSetpointHoldEnum.SetpointHoldOn)
    }
val automation = automation {
  isActive = true
  sequential {

    // When someone says "Prioritize thermostat setpoint"
    val unused =
      starter<_>(structure, VoiceStarter.OkGoogleEvent) {
        parameter(VoiceStarter.OkGoogleEvent.query("Prioritize thermostat setpoint"))
      }
    // make temperature setpoints override any preprogrammed schedules.
    action(thermostat, ThermostatDevice) {
      val unused2 =
        update(Thermostat) {
          setTemperatureSetpointHold(TemperatureSetpointHoldEnum.SetpointHoldOn)
        }
    }
  }

設定 ThermostatTrait.Attributes.temperatureSetpointHoldDuration,即可控制設定點保持功能的有效時間。

val thermostatTraitFlow: Flow<Thermostat?> =
  thermostat.type(ThermostatDevice).map { it.standardTraits.thermostat }.distinctUntilChanged()

val thermostatTrait: Thermostat = thermostatTraitFlow.first()!!

if (thermostatTrait.supports(Thermostat.Attribute.temperatureSetpointHoldDuration)) {
  // Set the setpoint hold duration to 60 minutes
  val unused = thermostatTrait.update { setTemperatureSetpointHoldDuration(60u) }
}
val automation = automation {
  isActive = true
  sequential {
    val stateReaderNode = stateReader<_>(thermostat, ThermostatDevice, Thermostat)
    val unused = starter<_>(thermostat, ThermostatDevice, Thermostat)

    // if the temperature setpoint hold duration is less than 60 minutes...
    condition() { expression = stateReaderNode.temperatureSetpointHoldDuration.lessThan(60u) }

    // ...and the automation hasn't been run for at least 24 hours...
    suppressFor(Duration.ofHours(24))

    // ...set the temperature setpoint hold duration to 60 minutes
    action(thermostat, ThermostatDevice) {
      val unused2 = update(Thermostat) { setTemperatureSetpointHoldDuration(60u) }
    }
  }
}

如要變更溫度設定點定溫模式 (決定溫度計 Hold 狀態結束的方式和時間),請呼叫 ThermostatTrait.SetTemperatureSetpointHoldPolicyCommand

有效值由 TemperatureSetpointHoldPolicyBitmap 決定。

Device API
val thermostatTraitFlow: Flow<Thermostat?> =
  thermostat.type(ThermostatDevice).map { it.standardTraits.thermostat }.distinctUntilChanged()

val thermostatTrait: Thermostat = thermostatTraitFlow.first()!!
if (thermostatTrait.supports(Thermostat.Attribute.temperatureSetpointHoldPolicy)) {

  // Set the temperature setpoint hold policy to holdDurationElapsedOrPresetChanged
  val unused =
    thermostatTrait.setTemperatureSetpointHoldPolicy(
      ThermostatTrait.TemperatureSetpointHoldPolicyBitmap(
        holdDurationElapsed = false,
        holdDurationElapsedOrPresetChanged = true,
      )
    )
}

val automation = automation {
  isActive = true
  sequential {

    // When someone says "Set my preferred hold duration",
    val unused =
      starter<_>(structure, VoiceStarter.OkGoogleEvent) {
        parameter(VoiceStarter.OkGoogleEvent.query("Set my preferred hold duration"))
      }

    // set the temperature setpoint hold policy to holdDurationElapsedOrPresetChanged
    action(thermostat, ThermostatDevice) {
      command(
        Thermostat.setTemperatureSetpointHoldPolicy(
          TemperatureSetpointHoldPolicyBitmap(
            holdDurationElapsed = false,
            holdDurationElapsedOrPresetChanged = true,
          )
        )
      )
    }
  }
}
