Setting up the solution

Code overview

This simple OpenWhisk function creates a MQTT client for the Prometeo solution. The client sends the following message as an IoT device to the IoT platform every minute:

{
    "firefighter_id": params.IOT_FIREFIGHTER_ID,
    "device_id": params.IOT_DEVICE_ID,
    "device_battery_level": (Math.random() * (0.00 - 100.00) + 0.0200).toFixed(2),
    "temperature": (Math.random() * 50).toFixed(2),
    "humidity": (Math.random() * 100).toFixed(2),
    "carbon_monoxide": (Math.random() * 150).toFixed(2),
    "nitrogen_dioxide": (Math.random() * 10).toFixed(2),
    "formaldehyde": (Math.random() * 10).toFixed(2),
    "acrolein": (Math.random() * 10).toFixed(2),
    "benzene": (Math.random() * 10).toFixed(2),
    "device_timestamp": getUTCTime()
}

Add device to the IoT platform

This solution was built for the IBM IoT platform, but will publish events to any MQTT server. If using the IBM IoT platform, add a new device to the platform first.

Use PrometeoDevice as the device type.

Edit configuration

The following parameters need to be set as local environment variables or as Github Actions environment secrets for the code to work. You can fill out .example.sh and run source ./.example.sh to create the environment variables locally.

IOT_HOST=""
IOT_PROTOCOL=""
IOT_USERNAME=""
IOT_PASSWORD=""
IOT_SECURE_PORT=""
IOT_PORT=""
IOT_CLIENTID=""
IOT_PEM=""
IOT_FIREFIGHTER_ID=""
IOT_DEVICE_ID=""

The IOT_CLIENTID needs to be of the format d:orgId:deviceType:deviceId. The deviceID should be the same as the Device ID shown in the image above. You can get the rest of the configuration from the IoT platform.

Deployment

Run locally

The action is a simple node.js application. Execute the following steps to run it locally:

  1. install the dependencies 
    npm install
  2. run the code 
    npm start

Run on IBM Cloud

  1. install the dependencies 
    npm install
  2. deploy the code 
    ibmcloud fn deploy
