# Group A `Group` is a representation of a grouping construct in the Hue Bridge, of which there are a number of specializations including serrving different purposes: * [`LightGroup`](#lightgroup): The default type of Group which collects lights and sensors * [`Luminaire`](#luminaire): A special type of group representing a Luminaire, the bridge will create these for these devices if you have any * [`Room`](#room): A Room that collects a number of lights and sensors togehter (a light and sensor can only belong to a single `Room`) * [`Entertainment`](#entertainment): A new special type of Group used for an Entertainment area for streaming (syncing light changes to a visualization via a seperate streaming API). Not all lights can be added to an Entertainment Group. * [`Zone`](#zone): A group that allows you to define a Zone that might be within a room, or extend across a number of rooms. This allows you to work around the `Room` limitations of lights and sensors only being able to belong to on Room. You cannot create these Object directly, but can either retrieve them from the Hue Bridge via the [Groups API](./groups.md) or create a new instance of them using the `v3.model` functions: * `v3.model.createLightGroup()` * `v3.model.createRoom()` * `v3.model.createZone()` * `v3.model.createEntertainment()` * [Common Group Properties and Functions](#common-group-properties-and-functions) * [id](#id) * [name](#name) * [lights](#lights) * [type](#type) * [action](#action) * [recycle](#recycle) * [sensors](#sensors) * [state](#state) * [toString()](#tostring) * [toStringDetailed()](#tostringdetailed) * [LightGroup](#lightgroup) * [Room](#room) * [class](#class) * [Zone](#zone) * [class](#class * [Entertainment](#entertainment) * [class](#class) * [locations](#locations) * [stream](#stream) ## Common Group Properties and Functions The properties and functions available for all `Group`s are: ## id The id for the group. * `get` ## name The name for the group. * `get` * `set` ## lights An array of light `id`s that are in the group * `get` ## type The type of group that this `Group` instance represents. * `get` The type can be one of the following values: * `Lunimarie`: Multisource Luminaire group * `Lighsource`: Multisource Luminaire group * `LightGroup`: A group of lights that can be controlled together * A light group is deleted by the bridge if you remove all the lights from it * `Room` * `Entertainment` * `Zone` ## action The Light state of one of the lamps in the group. * `get` ## recycle A flag indicating if the bridge can automatically remove the group. * `get` ## sensors An `Array` of sensor `id`s that are associated with the group, which cna be empty. * `get` ## state A state representation of the group. Which can contain details like `all_on` or `any_on` which indicate if all or any of the light members are currently on. `get` ### toString() The `toString()` function will obtain a simple `String` representation of the Scene. ###toStringDetailed() The `toStringDetailed()` function will obtain a more detailed representation of the Scene object. ## LightGroup The standard LightGroup has all the properties and functions defined in the [common group properties](#common-group-properties-and-functions). ## Room A group of lights that are physically located in the same place in a house. These behave like a standard group, but have a couple of differences: * A room can be empty and contain no lights * A light is only allowed in a single room * A room is not automatically deleted when all the lights are removed The `Room` Group has all the properties and functions as defined in the [common group properties](#common-group-properties-and-functions) as well as the following: ## class The `class` represents the `Zone` category as a `String`. * `get` * `set` The values that can be set for this on a `Room` are: -------------- | -------------- | ---------- `Living room` | `Kitchen` | `Dining` `Bedroom` | `Kids bedroom` | `Bathroom` `Nursery` | `Recreation` | `Office` `Gym` | `Hallway` | `Toilet` `Front door` | `Garage` | `Terrace` `Garden` | `Driveway` | `Carport` `Other` | | Since version 1.30 of the Hue Bridge API the following values can also be used: -------------- | ------------- | ---------- `Home` | `Downstairs` | `Upstairs` `Top floor` | `Attic` | `Guest room` `Staircase` | `Lounge` | `Man cave` `Computer` | `Studio` | `Music` `TV` | `Reading` | `Closet` `Storage` | `Laundry room` | `Balcony` `Porch` | `Barbecue` | `Pool` ## Zone A group of lights that can be controlled together. * A zone can be empty and contain no lights * A light is allowed to be in multiple zones (as opposed to only being able to belong to a single room) The `Zone` Group has all the properties and functions as defined in the [common group properties](#common-group-properties-and-functions) as well as the following: ## class The `class` represents the `Zone` category as a `String`. * `get` * `set` The values that can be set for this on a `Room` are: -------------- | -------------- | ---------- `Living room` | `Kitchen` | `Dining` `Bedroom` | `Kids bedroom` | `Bathroom` `Nursery` | `Recreation` | `Office` `Gym` | `Hallway` | `Toilet` `Front door` | `Garage` | `Terrace` `Garden` | `Driveway` | `Carport` `Other` | | Since version 1.30 of the Hue Bridge API the following values can also be used: -------------- | ------------- | ---------- `Home` | `Downstairs` | `Upstairs` `Top floor` | `Attic` | `Guest room` `Staircase` | `Lounge` | `Man cave` `Computer` | `Studio` | `Music` `TV` | `Reading` | `Closet` `Storage` | `Laundry room` | `Balcony` `Porch` | `Barbecue` | `Pool` ## Entertainment Represents an entertainment set up, which is a group of lights used to define targets for streaming along with defining position of the lights. The Entertainment Group has all the properties and functions as defined in the [common group properties](#common-group-properties-and-functions) as well as the following: * [class](#class) * [locations](#locations) * [stream](#stream) ## class The `class` represents the `Entertainment` category as a `String`. * `get` The values that can be set for this on a are: * `TV` * `Other` ## locations The locations of the lights in an `Entertainment` type Group which is an Object that maps the `id` of the light to an `Array` consisting of three integers inidicating the position in 3D space from the source. `get` ## stream The stream details object for an `Entertainment` type Group. `get` The stream object consists of the following keys and values: * `proxymode`: A string indicating the proxy mode * `proxynode`: A string which is an address string to a light in the bridge, e.g. `/lights/22` * `active`: A Boolean indicating whether or not the Entertainment is currently streaming * `owner`: If the Entertainment is currently streaming, this is the user id of the owner of the stream.
