Light

All Lights on the Bridge are built into a Light instance.

The Hue Bridge has multiple types of lights which are:

• On Off Light
• Dimmable Light
• Color Light
• Color Temperature Light
• Extended Color Light
  

Each instance of a Light will have different properties depending upon their capabilities of the underlying type.

Light Properties and Functions

id

The id for the light in the Bridge.

• get

name

The name for the light.

• get
• set

type

The type of the light.

• get

The known types of Lights (there may be more, and also variant of the strings):

* `On Off Light`
* `Dimmable Light`
* `Color Light` 
* `Color Temperature Light` 
* `Extended Color Light`  

modelid

The model id of the light

• get

manufacturername

The manufacturer name of the light.

• get

uniqueid

The unique id of the light in the Hue Bridge.

• get

productid

The product id for the light

• get

swversion

The software version number, if applicable for the light.

• get

swupdate

The software update object for the light.

• get

The Object if present for a light (not all support software updates) is of the form:

For a light that can be software updated:

{
  "state": "noupdates",
  "lastinstall": "2019-09-23T22:12:54"
}

For a light that does not support software updates:

{
  "state": "notupdatable",
  "lastinstall": null
}

state

The state of the light when it was retrieved from the Hue Bridge.

• get

This is an Object representation of a LightState, but is left as a raw Object.

capabilites

An Object representing all the capabilities of the Light. The details for the capabilities varies depending upon the Light product and manufacturer. Older lights may report nothing whereas new Hue lights used for Entertainment Streaming will report a lot of details in their capabilities.

• get

An example of an Extended Color Light capabilities:

"capabilities": {
    "certified": true,
    "control": {
        "mindimlevel": 5000,
        "maxlumen": 250,
        "colorgamuttype": "B",
        "colorgamut": [
            [
                0.675,
                0.322
            ],
            [
                0.409,
                0.518
            ],
            [
                0.167,
                0.04
            ]
        ],
        "ct": {
            "min": 153,
            "max": 500
        }
    },
    "streaming": {
        "renderer": true,
        "proxy": true
    }
}

colorGamut

Obtains the matched Color Gamut for the Light. This can be loaded from the Light capabilities object, or via a matching against the light modelid.

Only lights that support color will report a colorGamut (white lights will not have a color gamut).

• get

The result will either be null or an Object consisting of red, green and blue keys set to an Object with x, y values:

{
  red: {x: 0.692, y: 0.308},
  green: {x: 0.17, y: 0.7},
  blue: {x: 0.153, y: 0.048}
}

getSupportedStates()

The function getSupportedStates() will return an Array of String values that are the known states that can be set on the light.

Typically you would not need to use this, as the LightState object would be used to set the LightState on a Light in the API, but this can be used to help limit the setting that you can build into a LightState in a UI, or programmatically.

An example of this for an Extended Color Light is:

[
  "on",
  "bri",
  "hue",
  "sat",
  "effect",
  "xy",
  "ct",
  "alert",
  "colormode",
  "mode",
  "reachable",
  "transitiontime",
  "bri_inc",
  "sat_inc",
  "hue_inc",
  "ct_inc",
  "xy_inc"
]

An example for a Dimmable Light is:

[
  "on",
  "bri",
  "alert",
  "mode",
  "reachable",
  "transitiontime",
  "bri_inc"
]

toString()

The toString() function will obtain a simple String representation of the Light.

e.g.

Light
  id: 10

toStringDetailed()

The toStringDetailed() function will obtain a more detailed representation of the Light object.

e.g.

Light
  id: 14
  state: {"on":false,"bri":254,"alert":"select","mode":"homeautomation","reachable":false}
  swupdate: {"state":"noupdates","lastinstall":"2018-12-13T20:43:31"}
  type: "Dimmable light"
  name: "Hallway Entrance"
  modelid: "LWB004"
  manufacturername: "Philips"
  productname: "Hue white lamp"
  capabilities: {"certified":true,"control":{"mindimlevel":2000,"maxlumen":750},"streaming":{"renderer":false,"proxy":false}}
  config: {"archetype":"sultanbulb","function":"functional","direction":"omnidirectional","startup":{"mode":"powerfail","configured":true}}
  uniqueid: "00:17:xx:xx:xx:xx:xx:xx-0b"
  swversion: "5.127.1.26420"
