Variable ClusterInstanceConst

Type declaration

• Readonlyattributes: {
      lightSensorType: OptionalAttribute<number | null, any>;
      maxMeasuredValue: Attribute<number | null, any>;
      measuredValue: Attribute<number | null, any>;
      minMeasuredValue: Attribute<number | null, any>;
      tolerance: OptionalAttribute<number, any>;
  }

  • ReadonlylightSensorType: OptionalAttribute<number | null, any>

    The LightSensorType attribute specifies the electronic type of the light sensor. This attribute shall be set to one of the non-reserved values listed in LightSensorTypeEnum or null in case the sensor type is unknown.

    See

    MatterSpecification.v13.Cluster § 2.2.5.5

  • ReadonlymaxMeasuredValue: Attribute<number | null, any>

    The MaxMeasuredValue attribute indicates the maximum value of MeasuredValue that can be measured. A value of null indicates that this attribute is not defined. See Measured Value for more details.

    See

    MatterSpecification.v13.Cluster § 2.2.5.3

  • ReadonlymeasuredValue: Attribute<number | null, any>

    The MeasuredValue attribute represents the illuminance in Lux (symbol lx) as follows:

    • MeasuredValue = 10,000 x log10(illuminance) + 1,

    where 1 lx <= illuminance <= 3.576 Mlx, corresponding to a MeasuredValue in the range 1 to 0xFFFE. The MeasuredValue attribute can take the following values:

    • 0 indicates a value of illuminance that is too low to be measured,

    • MinMeasuredValue <= MeasuredValue <= MaxMeasuredValue under normal circumstances,

    • null indicates that the illuminance measurement is invalid.

    The MeasuredValue attribute is updated continuously as new measurements are made.

    See

    MatterSpecification.v13.Cluster § 2.2.5.1

  • ReadonlyminMeasuredValue: Attribute<number | null, any>

    The MinMeasuredValue attribute indicates the minimum value of MeasuredValue that can be measured. A value of null indicates that this attribute is not defined. See Measured Value for more details.

    See

    MatterSpecification.v13.Cluster § 2.2.5.2

  • Readonlytolerance: OptionalAttribute<number, any>

    See Measured Value.
