Usage

package main

import (
    "github.com/collinux/GoHue"
)

func main() {
    // It is recommended that you save the username from bridge.CreateUser
    // so you don't have to press the link button every time and re-auth.
    // When CreateUser is called it will print the generated user token.
    bridgesOnNetwork, _ := hue.FindBridges()
    bridge := bridgesOnNetwork[0]
    username, _ := bridge.CreateUser("someusernamehere")
    bridge.Login(username)

    lights, _ := bridge.GetAllLights()
    for _, light := range lights {
        light.SetBrightness(100)
        light.ColorLoop(true)
    }

    nightstandLight, _ := bridge.GetLightByName("Nightstand")
    nightstandLight.Blink(5)
    nightstandLight.SetName("Bedroom Lamp")

    lights[0].SetColor(hue.RED)

	Username  string
	Info      BridgeInfo
}

Bridge struct defines hardware that is used to communicate with the lights.

func FindBridges 

func FindBridges() ([]Bridge, error)

FindBridges will visit www.meethue.com/api/nupnp to see a list of bridges on the local network.

func NewBridge 

func NewBridge(ip string) (*Bridge, error)

NewBridge defines hardware that is compatible with Hue. The function is the core of all functionality, it's necessary to call `NewBridge` and `Login` or `CreateUser` to access any lights, scenes, groups, etc.

func (*Bridge) CreateScene 

func (bridge *Bridge) CreateScene(scene Scene) error

CreateScene posts a new scene configuration to the bridge.

func (*Bridge) CreateSchedule 

func (bridge *Bridge) CreateSchedule(schedule Schedule) error

CreateSchedule TODO: NOT TESTED, NOT FULLY IMPLEMENTED

func (*Bridge) CreateUser 

func (bridge *Bridge) CreateUser(deviceType string) (string, error)

CreateUser adds a new user token on the whitelist. The token is the first return value in this function which must be used with `Bridge.Login`. You cannot use a plaintext username like the argument provided in this function. This was done by Philips Hue for security reasons.

func (*Bridge) Delete 

func (bridge *Bridge) Delete(path string) error

Delete sends an http DELETE to the bridge

func (*Bridge) DeleteUser 

func (bridge *Bridge) DeleteUser(username string) error

func (*Bridge) FindNewLights 

func (bridge *Bridge) FindNewLights() error

FindNewLights makes the bridge search the zigbee spectrum for lights in the area and will add them to the list of lights available. If successful these new lights can be used by `Bridge.GetAllLights`

Notes from Philips Hue API documentation: The bridge will search for 1 minute and will add a maximum of 15 new lights. To add further lights, the command needs to be sent again after the search has completed. If a search is already active, it will be aborted and a new search will start. http://www.developers.meethue.com/documentation/lights-api#13_search_for_new_lights

GetSceneByName gets the attributes for the scene identified by a name

func (*Bridge) GetSchedule 

func (bridge *Bridge) GetSchedule(id string) (Schedule, error)
