Azure IOT Hub

​Many IOT devices can be configured to push messages to Microsoft Azure IOT Hub. IOT Hub can receive and collate messages from thousands of devices, and provide a single interface for applications such as Engine to securely connect to in order to receive realtime updates from any connected devices.
Connection via Node-RED
Engine supports connection to Azure IOT Hub via a local Node-RED docker container (at node-red:1880) which ships by default as part of all Engine deployments. Once the connection is configured, Engine modules will recieve realtime notifications from MS Azure IOT Hub via the Node-RED websocket.

Configuring Node-RED to connect to Azure IOT Hub
Prerequisite: First, ensure you've read the article on how Engine works with Node-RED​
1.Install the Node-RED connector for Azure IOT Hub, by running the below command on the VM/machine where Engine is installed:
docker exec -it node-red npm install node-red-contrib-azure-iot-hub
docker restart node-red
2.Access the Node-RED web interface by visiting http://localhost:1880 to configure Node-RED.
3.Create an "Azure IoT Hub Receiver" node. Connect it it to your IOT Hub by setting the connectionstring, which you will find in your Azure Portal, under your IOT Hub > Shared Access policies > iothubowner > Connection string-primary key See heading "Reading all messages received into Azure IoT Hub" for more details.
4.Create a "websocket output" node and connect the output of the Azure node to the input of the websocket node
