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);
});
});
