Open source library for communication with the Philips Hue bridge. This library covers all the Philips hue API calls! You can set the state of your lights, update the Bridge configuration, create groups, schedules etc.

This Portable Library is compatible with: .Net45, Windows 8, Windows Phone 8, Windows 10 Universal Apps and the Xamarin Platform! Download directly from NuGet Q42.HueApi on NuGet.

Some basic usage examples

Before you can communicate with the Philips Hue Bridge, you need to find the bridge and register your application:

IBridgeLocator locator = new HttpBridgeLocator();

//For Windows 8 and .NET45 projects you can use the SSDPBridgeLocator which actually scans your network. 
//See the included BridgeDiscoveryTests and the specific .NET and .WinRT projects
IEnumerable<string> bridgeIPs = await locator.LocateBridgesAsync(TimeSpan.FromSeconds(5));

Register your application

ILocalHueClient client = new LocalHueClient("ip");
var appKey = await client.RegisterAsync("mypersonalappname", "mydevicename");
//Save the app key for later use

If you already registered an appname, you can initialize the HueClient with the app's key:

client.Initialize("mypersonalappkey");

Main usage of this library is to be able to control your lights. We use a LightCommand for that. A LightCommand can be send to one or more / multiple lights. A LightCommand can hold a color, effect, on/off etc.

var command = new LightCommand();
command.On = true;

There are some helpers to set a color on a command:

//Turn the light on and set a Hex color for the command (see the section about Color Converters)
command.TurnOn().SetColor(new RGBColor("FF00AA"))

LightCommands also support Effects and Alerts

//Blink once
command.Alert = Alerts.Once;

//Or start a colorloop
command.Effect = Effects.ColorLoop;

Once you have composed your command, send it to one or more lights

client.SendCommandAsync(command, new List<string> { "1" });

Or send it to all lights

client.SendCommandAsync(command);

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. Q42.HueApi has 3 different color converters out of the box. They are in a seperate package and it's easy to create your own color converter.

• Original: The original converter based on a large XY array.
• OriginalWithModel: Does not use the large XY array, but should produce the same result and uses the lamp model.
• HSB: Converts based on Hue, Brightness and Saturation.

How to use a color converter? Add one of the following usings:
using Q42.HueApi.ColorConverters.Original
using Q42.HueApi.ColorConverters.OriginalWithModel
using Q42.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!

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.
You need an Access Token and a Bridge Id. Please refer to the Philips Hue API documentation on how to obtain them. NOTE Remote API support is untested. Testing and PRs are very much appreciated.

IRemoteHueClient remoteHueClient =  new RemoteHueClient("access token");
remoteHueClient.Initialize("bridge id", "whitelist_id");

After the setup, you can send normal commands to the remote API:

remoteHueClient.SendCommandAsync(command, new List<string> { "1" });

Download the source from GitHub or get the compiled assembly from NuGet Q42.HueApi on NuGet.
