How to use?

Some basic usage examples

Use the LocalHueApi:

var localHueApi = new LocalHueApi("BRIDGE_IP", "KEY");

//Make sure the user has pressed the button on the bridge before calling RegisterAsync
//It will throw an LinkButtonNotPressedException if the user did not press the button
var regResult = await LocalHueClient.RegisterAsync("BRIDGE_IP", "mypersonalappname", "mydevicename");

//Save the app key for later use and use it to initialize LocalHueApi
var appKey = regResult.Username;

Change the lights:

var lights = await localHueApi.GetLightsAsync();
var id = all.Data.Last().Id; //Pick a light

var req = new UpdateLight()
	.TurnOn()
	.SetColor(new ColorConverters.RGBColor("FF0000"));
	
var result = await localHueApi.UpdateLightAsync(id, req);

API Reference

Use the API reference provided by Hue to discover the capabilities of the API. https://developers.meethue.com/develop/hue-api-v2/api-reference/

EventStream

Listen to the new EventStream to get notified by the Hue Bridge when new events occur.

localHueApi.OnEventStreamMessage += EventStreamMessage;
localHueApi.StartEventStream();

void EventStreamMessage(List<EventStreamResponse> events)
{
  Console.WriteLine($"{events.Count} new events");

  foreach(var hueEvent in events)
  {
    foreach(var data in hueEvent.Data)
    {
      Console.WriteLine($"Data: {data.Metadata?.Name} / {data.IdV1}");
    }
  }
}

//localHueApi.StopEventStream();

Sample usage can be found in the included Console Sample App: HueApi.ConsoleSample

Clip V2 API

Philips Hue has developed a new Clip V2 API. This library has support for the new Clip V2 APIs. Philips Hue is still developing these APIs and new functionality is added regularly. Please create an issue or PR if you need something that is not supported yet.

Support for Hue Entertainment.

Check out the HueApi.Entertainment documentation
Read about the Philips Entertainment API

Remote API

There is also a Philips Hue Remote API. It allows you to send commands to a bridge over the internet. You can request access here: http://www.developers.meethue.com/content/remote-api
Q42.HueApi is compatible with the remote API. There's a sample app and documentation can be found here: https://github.com/michielpost/Q42.HueApi/blob/master/RemoteApi.md

For remote usage with the new CLIP v2 API, use the new RemoteHueApi("KEY", "token")

Color Conversion

The Philips Hue lights work with Brightness, Saturation, Hue and X, Y properties. More info can be found in the Philips Hue Developer documentation: http://www.developers.meethue.com/documentation/core-concepts#color_gets_more_complicated It's not trivial to convert the light colors to a color system developers like to work with, like RGB or HEX. HueApi has 2 different color converters out of the box. They are in a seperate package and it's easy to create your own color converter.

The HueApi.ColorConverters NuGet package contains:

Original: The original converter based on a large XY array.
HSB: Converts based on Hue, Brightness and Saturation.

How to use a color converter? Add one of the following usings:
using HueApi.ColorConverters.Original
using HueApi.ColorConverters.HSB

This will add extension methods to Light, State and LightCommand. So you can set the color using new RGBColor() and convert the State back to RGBColor

Pull Requests with improvements to the color conversion are always welcome!
