Tipo di dispositivo delle API Home Tratti App di esempio Kotlin Caso d'uso

Termostato

ThermostatDevice

home.matter.0000.types.0301

Un dispositivo in grado di avere sensori integrati o separati per temperatura, umidità o presenza e che consente di impostare la temperatura desiderata. Un termostato è in grado di inviare notifiche relative ai requisiti di riscaldamento e/o raffreddamento a un'unità di riscaldamento/raffreddamento (ad esempio un'unità di trattamento dell'aria interna) o di includere un meccanismo per controllare direttamente un'unità di riscaldamento o raffreddamento.

Supporto dell'API Automation

Nell'API Automation sono supportati i seguenti elementi e tratti di Thermostat.

Ottenere la temperatura ambiente

Ottenere la temperatura ambiente utilizzando il termostato

Per ottenere la temperatura ambiente del termostato utilizzando il tratto Thermostat, leggi l'attributo localTemperature.

// 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."))
    }
  }
}

Ottenere la temperatura ambiente utilizzando TemperatureMeasurement

Per ottenere la temperatura ambiente del termostato utilizzando il tratto TemperatureMeasurement, leggi l'attributo measuredValue.

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()) }
  }
}

Ottenere la temperatura media utilizzando ExtendedThermostat

Per ottenere la temperatura media di più sensori, leggi l'attributo averageLocalTemperature della caratteristica ExtendedThermostat.

// 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()) }
  }
}

Ottenere l'umidità ambientale

Per ottenere l'umidità relativa dell'ambiente del termostato utilizzando la caratteristica RelativeHumidityMeasurement, leggete l'attributo measuredValue.

// 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()) }
  }
}

Selezionare la scala di temperatura visualizzata

Per modificare l'unità di misura della temperatura utilizzata per il display del termostato, imposta l'attributo temperatureDisplayMode di ThermostatUserInterfaceConfigurationTrait su TemperatureDisplayModeEnum.Celsius o TemperatureDisplayModeEnum.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)
      }
    }
  }
}

Modificare la modalità di funzionamento

Il termostato può essere limitato a determinate modalità di funzionamento, definite da ThermostatTrait.SystemModeEnum, impostando l'attributo ThermostatTrait.Attributes.systemMode, cuyos valores están definidos por ThermostatTrait.Attributes.SystemModeEnum.

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))
    }
  }
}

Quando il termostato è impostato su SystemModeEnum.Auto, è possibile leggere ulteriori informazioni sulla modalità di funzionamento del termostato da ThermostatTrait.Attributes.thermostatRunningMode che viene compilato con i valori di ThermostatRunningModeEnum.

// 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 è progettato per semplificare il processo di impostazione della modalità di funzionamento nelle automazioni. Per cambiare la modalità di funzionamento del termostato utilizzando il pulsante SimplifiedThermostatTrait, usa SetSystemModeCommand, i cui valori sono definiti da SimplifiedThermostatTrait.SystemModeEnum.

Questo trait è disponibile solo per l'utilizzo con l'API Automation.

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))
    }
  }
}

Per determinare le modalità di sistema in cui può funzionare un termostato, leggi il messaggio ThermostatTrait.Attributes.controlSequenceOfOperation, i cui valori sono determinati da ThermostatTrait.ControlSequenceOfOperationEnum.

// 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))
      }
    }
  }
}

Modificare la modalità di funzionamento della programmazione

La modalità di funzionamento della programmazione del termostato può essere modificata utilizzando il valore thermostatProgrammingOperationMode del messaggio Thermostat, i cui valori sono definiti dal messaggio ProgrammingOperationModeBitmap.

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))
      }
    }
  }
}

Modificare il set-point della temperatura

Per modificare il setpoint della temperatura utilizzando il pulsante Thermostat, chiama 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))
    }
  }
}

Dare la priorità a un set-point di temperatura

Puoi fare in modo che un setpoint della temperatura abbia la precedenza su una programmazione preprogrammata impostando l'attributo temperatureSetpointHold di ThermostatTrait su TemperatureSetpointHoldEnum.SetpointHoldOn oppure puoi fare in modo che la programmazione abbia la precedenza impostandola su TemperatureSetpointHoldEnum.SetpointHoldOff.

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)
        }
    }
  }

Imposta ThermostatTrait.Attributes.temperatureSetpointHoldDuration per controllare per quanti minuti è attiva la mantenimento del setpoint.

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) }
    }
  }
}

Per modificare il criterio di blocco del setpoint della temperatura, che determina come e quando termina lo stato di blocco del termostato, chiama ThermostatTrait.SetTemperatureSetpointHoldPolicyCommand.

I valori validi sono determinati da TemperatureSetpointHoldPolicyBitmap.
