var mqtt = require('mqtt')

Define variables

var broker = 'PASTE_HOST_HERE'
var deviceToken  = 'PASTE_DEVICE_TOKEN_HERE'
var deviceId  = 'PASTE_DEVICE_ID_HERE'

Setup MQTT Client

var options = {
    port: 8883,
    keepalive: 60,
    secureProtocol: 'TLSv1_method'
    clientId: deviceId,
    username: deviceId,
    password: deviceToken,
};

var client = mqtt.connect(broker,options)

Prepare Data

const data = {
  key1: 'value1',
  key2: 'value2',
