Run a SiteManager to send data to the IoT Hub

You need a B&R SiteManager to collect field data from your machines and send them to the IoT Hub! See B&R Website for further information!

Add new consumer group to your event hub

Go to Azure Portal and select your IoT hub. Click Endpoints -> Events, add a new consumer group and then save it.

Deploy to Azure web application

Go to Azure Portal to create your own Azure web app service. Then do the following setting:

• Go to Application settings, add key/value pairs Azure.IoT.IoTHub.ConnectionString and Azure.IoT.IoTHub.ConsumerGroup to App settings slot.
• Go to Deployment options, select Github repository to deploy your web app.
• Go to Deployment credentials, set your deploy username and password.
• In the Overview page, note the GitHub project URL.
• The code will then be synchronized to your WebApp
• You can now view the page to see the real-time data chart.

Local deploy

• Open a console and set the following environment variable:

  • set Azure.IoT.IoTHub.ConnectionString=<your connection string>
  • set Azure.IoT.IoTHub.ConsumerGroup=<your consumer group name>

• Open ./public/javascripts/index.js, and change the code around line 69
