Turn light on off

Here is an example to turn a light on or off and set brightness level

// Initialize COM Port
ZigBeeSerialPort zigbeePort = new ZigBeeSerialPort("COM4");

// Initialize dongle hardware e.g. CC2531
IZigBeeTransportTransmit dongle = new ZigBeeDongleTiCc2531(zigbeePort);

// Initialize NetworkManager
ZigBeeNetworkManager networkManager = new ZigBeeNetworkManager(dongle);

// Send OnCommand
await networkManager.Send(endpointAddress, new OnCommand());

// Get node by it's network address
var node = networkManager.GetNode(4711);

// Create a endpoint address object
ZigBeeEndpointAddress endpointAddress = null;
// Get  default endpoint
var endpoint = node.Endpoints.Values.FirstOrDefault();

if (endpoint != null)
{
    // Get endpoint address
    endpointAddress = endpoint.GetEndpointAddress();
} 
else 
{
   throw new Exception("No Endpoint found!");
}

// Send OffCommand
await networkManager.Send(endpointAddress, new OffCommand());

// Send MoveToLevelCommand for setting brightness
var command = new MoveToLevelWithOnOffCommand()
{
    // Level from 0 to 255, where 255 = 100 %
    Level = byte.Parse(level),
    // Time for changing (smoothly overflow)
    TransitionTime = ushort.Parse(time)
};

await networkManager.Send(endpointAddress, command);
