The HomeKit light sensors have a number of common options and are grouped here.

The following configuration is available:

{
  "c": { "io": [ [ [ 13 ], 2 ] ], "l": 13 },
  "a": [{
    "t": 50,
    "n": 0,
    "f": 14357564.33,
    "po": 1.396066767,
    "re": 8550
  }]
}

Sensor type is defined by the "n" key contained within the service object.

Only needed for ESP32, because ESP8266 has only one ADC pin.

Remember to declare GPIO as ADC into "io":[...] array. See GPIOs Configuration

Array with information about sensor. For BH1750, "dt" key must be in this format: "dt" : [I2C Bus, Address]

Code Address as follow:

TO-DO

TO-DO

Sensor polling time is defined by the "j" key contained within the service object.

A light sensor is polled on a regular basis to read the latest values. These values are then posted to HomeKit. If this option is not specified then the sensor will be polled once every 3 seconds.

Light sensor factor is defined by the "f" key contained within the service object.

The option uses is a floating point value, accurate to 1 decimal place e.g. 1.1

Light sensor offset is defined by the "o" key contained within the service object.

The option uses is a floating point value, accurate to 1 decimal place e.g. 1.1

Wildcard Actions "y[n]" are supported by this service. The supported list is:
