Automation API のサポート

Automation API では、次のサーモスタットのトレイトと要素がサポートされています。

周囲温度を取得する

サーモスタットを使用して周囲温度を取得する

Thermostat トレイトを使用してサーモスタットの周囲温度を取得するには、localTemperature 属性を読み取ります。

Device APIAutomation API
// 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."))
    }
  }
}

TemperatureMeasurement を使用して周囲温度を取得する

TemperatureMeasurement トレイトを使用してサーモスタットの周囲温度を取得するには、measuredValue 属性を読み取ります。

Device APIAutomation API
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()) }
  }
}

ExtendedThermostat を使用して平均気温を取得する

複数のセンサーの平均温度を取得するには、ExtendedThermostat トレイトの averageLocalTemperature 属性を読み取ります。

Device APIAutomation API
// 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()) }
  }
}

周囲の湿度を取得する

RelativeHumidityMeasurement トレイトを使用してサーモスタットの周囲湿度を取得するには、measuredValue 属性を読み取ります。

Device APIAutomation API
// 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()) }
  }
}

表示される温度目盛りを選択する

サーモスタット ディスプレイに表示される温度の測定単位を変更するには、ThermostatUserInterfaceConfigurationTraittemperatureDisplayMode 属性を TemperatureDisplayModeEnum.Celsius または TemperatureDisplayModeEnum.Fahrenheit に設定します。

Device APIAutomation API
// 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)
      }
    }
  }
}

動作モードを変更する

サーモスタットは、ThermostatTrait.Attributes.systemMode 属性を設定して、ThermostatTrait.SystemModeEnum で定義された特定の動作モードに制限できます。この属性の値は ThermostatTrait.Attributes.SystemModeEnum で定義されます。

Device APIAutomation API
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))
    }
  }
}

サーモスタットが SystemModeEnum.Auto に設定されている場合、サーモスタットの実行モードに関する追加情報を ThermostatTrait.Attributes.thermostatRunningMode から読み取ることができます。ThermostatTrait.Attributes.thermostatRunningMode には ThermostatRunningModeEnum の値が入力されます。

Device APIAutomation API
// 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 は、自動化で動作モードを設定するプロセスを効率化するように設計されています。SimplifiedThermostatTrait を使用してサーモスタットの運転モードを変更するには、SetSystemModeCommand を使用します。この値は SimplifiedThermostatTrait.SystemModeEnum で定義されます。

この特性は Automation API でのみ使用できます。

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))
    }
  }
}

サーモスタットが動作できるシステム モードを特定するには、ThermostatTrait.Attributes.controlSequenceOfOperation を読み取ります。この値は ThermostatTrait.ControlSequenceOfOperationEnum によって決まります。

Device APIAutomation API
// 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))
      }
    }
  }
}

プログラミングの動作モードを変更する

サーモスタットのプログラミング オペレーション モードは、ThermostatthermostatProgrammingOperationMode を使用して変更できます。この値は ProgrammingOperationModeBitmap によって定義されます。

Device APIAutomation API
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))
      }
    }
  }
}

設定温度を変更する

Thermostat を使用して設定温度を変更するには、ThermostatTrait.SetpointRaiseLowerCommand を呼び出します。

Device APIAutomation API
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))
    }
  }
}

設定温度に優先順位を付ける

事前プログラムされたスケジュールよりも温度設定優先にするには、ThermostatTraittemperatureSetpointHold 属性を TemperatureSetpointHoldEnum.SetpointHoldOn に設定します。スケジュールを優先するには、TemperatureSetpointHoldEnum.SetpointHoldOff に設定します。

Device APIAutomation API
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)
        }
    }
  }

ThermostatTrait.Attributes.temperatureSetpointHoldDuration を設定して、設定温度保持が有効な時間を制御します。

Device APIAutomation API
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) }
    }
  }
}

サーモスタットの保持状態を終了する方法とタイミングを決定する温度設定値の保持ポリシーを変更するには、ThermostatTrait.SetTemperatureSetpointHoldPolicyCommand を呼び出します。

有効な値は TemperatureSetpointHoldPolicyBitmap によって決まります。

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,
          )
        )
      )
    }
  }
}
