Use this library to quickly connect your device to Cayenne Cloud. For more information see our [API Documentation](http://www.cayenne-mydevices.com/docs/#bring-your-own-thing-api-mqtt-messaging-topics)

```

npm install cayennejs

```

```javascript

var Cayenne = require('cayennejs');

// Initiate MQTT API

const cayenneClient = new Cayenne.MQTT({

  username: "foobar",

  password: "secret",

  clientId: "thing-id"

});

cayenneClient.connect((err, mqttClient) => {

  // dashboard widget automatically detects datatype & unit

  cayenneClient.kelvinWrite(3, 65);

  // sending raw values without datatypes

  cayenneClient.rawWrite(4, 123);

  // subscribe to data channel for actions (actuators)

  cayenneClient.on("cmd9", function(data) {

    console.log(data);

  });

});
