Pilih skala suhu yang ditampilkan

Untuk mengubah satuan pengukuran suhu yang digunakan untuk tampilan termostat, tetapkan atribut temperatureDisplayMode ThermostatUserInterfaceConfigurationTrait ke TemperatureDisplayModeEnum.Celsius atau TemperatureDisplayModeEnum.Fahrenheit.

Device 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) }
}

Automation API

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)
      }
    }
  }
}

Mengubah mode operasi

Termostat dapat dibatasi pada mode operasi tertentu, yang ditentukan oleh ThermostatTrait.SystemModeEnum, dengan menetapkan atribut ThermostatTrait.Attributes.systemMode, yang nilainya ditentukan oleh ThermostatTrait.Attributes.SystemModeEnum.

Device 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) }
}

Automation API

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))
    }
  }
}

Saat termostat disetel ke SystemModeEnum.Auto, informasi tambahan tentang mode operasi termostat dapat dibaca dari ThermostatTrait.Attributes.thermostatRunningMode yang diisi dengan nilai dari ThermostatRunningModeEnum.

Device 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

Automation API

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 dirancang untuk menyederhanakan proses penetapan mode operasi dalam otomatisasi. Untuk mengubah mode pengoperasian termostat menggunakan SimplifiedThermostatTrait, gunakan SetSystemModeCommand, yang nilainya ditentukan oleh SimplifiedThermostatTrait.SystemModeEnum.

Sifat ini hanya tersedia untuk digunakan dengan Automation API.

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))
    }
  }
}

Untuk menentukan mode sistem yang dapat digunakan termostat, baca ThermostatTrait.Attributes.controlSequenceOfOperation, yang nilainya ditentukan oleh ThermostatTrait.ControlSequenceOfOperationEnum.

Device API

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

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

Automation API

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))
      }
    }
  }
}

Mengubah mode operasi pemrograman

Mode operasi pemrograman termostat dapat diubah menggunakan thermostatProgrammingOperationMode Thermostat, yang nilainya ditentukan oleh ProgrammingOperationModeBitmap.

Device 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,
        )
      )
    }
}

Automation API

// 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))
      }
    }
  }
}

Mengubah titik penyetelan suhu

Untuk mengubah setpoint suhu menggunakan Thermostat, panggil ThermostatTrait.SetpointRaiseLowerCommand.

Device 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)

Automation API

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))
    }
  }
}

Memprioritaskan titik penyetelan suhu

Anda dapat membuat setpoint suhu lebih diutamakan daripada jadwal yang telah diprogram sebelumnya dengan menetapkan atribut temperatureSetpointHold ThermostatTrait ke TemperatureSetpointHoldEnum.SetpointHoldOn, atau membuat jadwal lebih diutamakan dengan menetapkannya ke TemperatureSetpointHoldEnum.SetpointHoldOff.

Device 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)
    }

Automation API

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)
        }
    }
  }

Tetapkan ThermostatTrait.Attributes.temperatureSetpointHoldDuration untuk mengontrol berapa menit waktu aktif untuk mempertahankan setpoint.

Device 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) }
}

Automation API

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) }
    }
  }
}

Untuk mengubah kebijakan penahanan setpoint suhu, yang menentukan cara dan waktu status Penahanan termostat berakhir, panggil ThermostatTrait.SetTemperatureSetpointHoldPolicyCommand.

Nilai yang valid ditentukan oleh TemperatureSetpointHoldPolicyBitmap.

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,
          )
        )
      )
    }
  }
}
