Pareto Anywhere for Azure

Pareto Anywhere for Azure is the open source middleware that unlocks the value of the ambient data arriving at your Azure IoT Hub.

Overview of Pareto Anywhere for Azure

Pareto Anywhere for Azure runs efficiently as a stateless Azure Function, triggered by data forwarded from IoT infrastructure, such as Aruba APs, to Azure IoT Hub.

Pareto Anywhere for Azure provides a single standard stream of real-time data, regardless of the underlying devices & technologies, which include Bluetooth Low Energy and EnOcean Alliance. Dynamic ambient (dynamb) data is output as JSON to Azure Event Hub from which it is easily relayed to any store, stream processor and/or application.

Getting Started

Follow our step-by-step tutorials to deploy Pareto Anywhere for Azure:

Learn "owl" about the dynamb JSON data output:

Deployment using ARM templates

Pareto Anywhere for Azure can be deployed in minutes to an Azure Resource Group using the infrastructure-as-code Azure Resource Manager (ARM) templates found in the /deployments folder of this repository. The only prerequisites are:

  • an Azure account
  • an Azure subscription
  • an Azure Resource Group

Step 1: Deploy an IoT Hub and Device Provisioning Service

If the Azure Resource Group already includes an IoT Hub, skip ahead to Step 2. Otherwise, either manually create an IoT Hub or deploy one to a Resource Group via ARM template by clicking the Deploy link below:

Deploy IoT Hub and DPS

Step 2: Deploy Pareto Anywhere for Azure and supporting resources

Deploy to a Resource Group via ARM template by clicking the Deploy link below:

Deploy Pareto Anywhere for Azure

The ARM template will deploy the pareto-anywhere-azure Azure Function under the Windows Consumption plan which strikes a balance between installation ease & speed, and operational costs. Consult the official ARM template documentation or contact your Microsoft rep to adapt these templates to your requirements.

Update an existing deployment

Update an existing deployment's function app to the latest version of Pareto Anywhere for Azure via ARM template by clicking the Deploy link below:

Manual Installation

Clone this repository and, from the root of the pareto-anywhere-azure folder, install the package dependencies with the following command:

npm install

Then, in that same folder, create a file called local.settings.json, and paste in the following contents:

{
  "IsEncrypted": false,
  "Values": {
    "FUNCTIONS_WORKER_RUNTIME": "node",
    "AzureWebJobsStorage": "...",
    "EventHubConnectionString": "...",
    "WebPubSubConnectionString": "...",
    "iot_hub_name": "...",
    "event_hub_name": "...",
    "web_pub_sub_hub_name": "..."
  }
}

Replace the "..." values with the appropriate strings from the Azure Portal, as explained in our Run Pareto Anywhere for Azure tutorial.

Running locally

With the Azure CLI installed, run pareto-anywhere-azure locally from its root folder with the following command:

func start

Then browse to localhost:7071/app/ to observe data in the web app served by the function, and to localhost:7071/app/status/ to observe the individual detected devices and their respective JSON data.

Running on Azure

With the Azure CLI installed, push pareto-anywhere-azure to Azure with the following command:

func azure functionapp publish <APP_NAME>

Initially, and anytime there are changes to local.settings.json, append the flag --publish-local-settings -i to the above.

Browse to <APP_NAME>.azurewebsites.net/app/ to observe data in the web app served by the function, and to <APP_NAME>.azurewebsites.net/app/status/ to observe the individual detected devices and their respective JSON data.

Data Structure

pareto-anywhere-azure outputs events to the Event Hub and to the Web PubSub (for consumption in the web app) using the following structure:

{
  "type": "dynamb",
  "data": { }
}

The type is always dynamb (but raddec and spatem can be accommodated in future). And the data is the dynamb data structure itself: see the reelyActive Developers Cheatsheet for details.

An example of an event from a temperature & humidity sensor would be as follows:

{
  "type": "dynamb",
  "data": {
    "deviceId": "ac233f000000",
    "deviceIdType": 2,
    "timestamp": 1645568542222,
    "temperature": 21.77734375,
    "relativeHumidity": 64.90625
  }
}

Web Apps

The web apps provide an intuitive visualisation of the real-time event stream:

Pareto Anywhere for Azure web app

Browse to the web apps at:

  • <APP_NAME>.azurewebsites.net/app/
  • <APP_NAME>.azurewebsites.net/app/status/

Be sure to include the trailing slash (/) to ensure the web content is loaded correctly.

The web apps and all their dependencies are served by the Azure Function itself from the /serveWebApp folder and its subfolders. Simply edit the index.html files and the dependencies as required, and the changes will appear as soon as the function restarts.

See the reelyActive Web Style Guide to facilitate customisation, and the beaver.js and cuttlefish.js client-side modules which collect and render the real-time dynamic ambient data, respectively.

GitHub Codespaces

pareto-anywhere-azure supports GitHub Codespaces for development/deployment within the browser rather than a local installation. The project Codespace is configured to include:

  • Node.js
  • Azure CLI
  • Azure Functions Core Tools
  • Port forwarding on 7071

GitHub Actions

pareto-anywhere-azure supports GitHub Actions to automate the deployment of Azure resources. This is currently under development, with experimental workflows available in the .github/workflows subfolder.

Project History

Pareto Anywhere for Azure evolved from pareto-anywhere, retaining the stateless processing modules such as the advlib libraries, facilitating efficient operation as a stateless Azure Function.

pareto-anywhere-azure was initially prototyped as aruba-iot-advlib-azure-function.
