API de automação

val automation = automation {
  sequential {
    val starterNode = starter<_>(thermostat, ThermostatDevice, Thermostat)

    // If the temperature is higher than 35C...
    // `localTemperature` is in one hundredth of a degree Celsius.
    condition { expression = starterNode.localTemperature greaterThan 3500 }

    // ...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."))
    }
  }
}

Receber a temperatura ambiente usando TemperatureMeasurement

Para receber a temperatura ambiente do termostato usando a característica TemperatureMeasurement, leia o atributo measuredValue.

API Device

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

val localTemp: Short? = temperatureTraitFlow.first()?.measuredValue

API de automação

val automation = automation {
  sequential {
    val temperature = starter<_>(thermostat, ThermostatDevice, TemperatureMeasurement)
    val stateReaderNode = stateReader<_>(light, DimmableLightDevice, OnOff)
    condition() {
      val expr1 = temperature.measuredValue greaterThanOrEquals 3500
      val expr2 = stateReaderNode.onOff equals true
      expression = expr1 and expr2
    }
    action(light, DimmableLightDevice) { command(OnOff.on()) }
  }
}

Receber a temperatura média usando ExtendedThermostat

Para saber a temperatura média de vários sensores, leia o atributo averageLocalTemperature da característica ExtendedThermostat.

API Device

// 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 }

      val expr2 = stateReaderNode.onOff equals true
      expression = expr1 and expr2
    }
    // Turn on the light
    action(light, DimmableLightDevice) { command(OnOff.on()) }
  }
}

Conferir a umidade do ambiente

Para receber a umidade ambiente do termostato usando a característica RelativeHumidityMeasurement, leia o atributo measuredValue.

API Device

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

val localHumidity: UShort? = humidityTraitFlow.first()?.measuredValue

API de automação

val automation = automation {
  sequential {
    val humidity = starter<_>(thermostat, HumiditySensorDevice, RelativeHumidityMeasurement)

      expression = expr1 and expr2
    }
    // Turn on the light
    action(light, DimmableLightDevice) { command(OnOff.on()) }
  }
}

Selecione a escala de temperatura mostrada

Para mudar a unidade de medida de temperatura usada no display do termostato, defina o atributo temperatureDisplayMode do ThermostatUserInterfaceConfigurationTrait como TemperatureDisplayModeEnum.Celsius ou TemperatureDisplayModeEnum.Fahrenheit.

API Device

// 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) }
}

API de automação

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)
      }
    }
  }
}

Mudar o modo de operação

O termostato pode ser limitado a determinados modos de operação, definidos por ThermostatTrait.SystemModeEnum, ao definir o atributo ThermostatTrait.Attributes.systemMode, cujos valores são definidos por ThermostatTrait.Attributes.SystemModeEnum.

API Device

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) }
}

API de automação

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))
    }
  }
}

Quando o termostato está definido como SystemModeEnum.Auto, é possível ler mais informações sobre o modo de execução do termostato em ThermostatTrait.Attributes.thermostatRunningMode que é preenchido com valores de ThermostatRunningModeEnum.

API Device

// 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

API de automação

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."))
    }
  }
}

O SimplifiedThermostatTrait foi projetado para simplificar o processo de definição do modo de operação em automações. Para mudar o modo de operação do termostato usando o SimplifiedThermostatTrait, use o SetSystemModeCommand, cujos valores são definidos por SimplifiedThermostatTrait.SystemModeEnum.

Essa característica só pode ser usada com a API Automation.

API de automação

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))
    }
  }
}

Para determinar os modos de sistema em que um termostato pode operar, leia o ThermostatTrait.Attributes.controlSequenceOfOperation, cujos valores são determinados pelo ThermostatTrait.ControlSequenceOfOperationEnum.

API Device

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

val controlSequenceOfOperation: ThermostatTrait.ControlSequenceOfOperationEnum? =
  standardTraitFlow.first()?.controlSequenceOfOperation

API de automação

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))
      }
    }
  }
}

Mudar o modo de operação de programação

O modo de operação de programação do termostato pode ser alterado usando o Thermostat thermostatProgrammingOperationMode, cujos valores são definidos pelo ProgrammingOperationModeBitmap.

API Device

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,
        )
      )
    }
}

API de automação

// 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))
      }
    }
  }
}

Mudar a temperatura programada

Para mudar a temperatura programada usando o Thermostat, chame o ThermostatTrait.SetpointRaiseLowerCommand.

API Device

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.
// `amount` is in one tenth of a degree Celsius.
thermostatTrait.setpointRaiseLower(amount = -10, mode = SetpointRaiseLowerModeEnum.Cool)

API de automação

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
    // `occupiedCoolingSetpoint` is in one hundredth of a degree C.
    condition() { expression = stateReaderNode.occupiedCoolingSetpoint greaterThan 1900 }

    // lower the temperature setpoint by 5 degrees C
    // Setpoint amount here is in one tenth of a degree Celsius.
    action(thermostat, ThermostatDevice) {
      command(Thermostat.setpointRaiseLower(SetpointRaiseLowerModeEnum.Cool, -50))
    }
  }
}

Priorizar uma temperatura programada

Para que um ponto de ajuste de temperatura tenha precedência sobre uma programação predefinida, defina o atributo temperatureSetpointHold do ThermostatTrait como TemperatureSetpointHoldEnum.SetpointHoldOn, ou defina a programação como TemperatureSetpointHoldEnum.SetpointHoldOff para que ela tenha precedência.

API Device

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)
    }

API de automação

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)
        }
    }
  }

Defina ThermostatTrait.Attributes.temperatureSetpointHoldDuration para controlar por quantos minutos uma retenção de ponto de ajuste fica ativa.

API Device

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) }
}

API de automação

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) }
    }
  }
}
