How to use the Flow Programming Kickstart
The flow programming Kickstart sets up a ready-to-use NodeRED Instance to visually create your IoT applications without a single line of code. NodeRED lets you connect functional building blocks together to perform actions on events, events can be messages received on your IoT Hub.
Select the IoT Hub and device to use with the Kickstart.Important:
Currently only devices supporting insecure connections are allowed for this IoT Kickstart.
Choose the geographical region to deploy your Kickstart.
Set a password for the Kickstart’s dashboard.
Click Create a Kickstart to launch the installation of the software stack.
A very simple application will be provisioned for you. It simply outputs any message’s contents to NodeRED debug panel.
To achieve this, an
MQTT input “node” (with the correct settings) is connected to a
Click IoT Hub in the IoT Station section of the side menu. The list of your IoT Hubs displays.
Click the name of the IoT Hub you want to configure. The hub’s overview page displays.
Click Devices to display the configuration of the device.
Click Add devices in the devices tab. The Create a Device wizard displays.
Enter a name for the device and allow insecure connections.
Click Add a Device to your Hub. The details of the device display. Take a note of the Device ID:
Open a web browser on your local computer and point it to the NodeRED web interface at
http://<your_flow_programming_instance_ip>:1880. Log into the panel using the password set during the Kickstart creation.
Go to the debug panel by clicking on the “bug” icon, on the top right of your screen.
Open a terminal on your local computer and run the following command:
mosquitto_pub -h iot.fr-par.scw.cloud -i <device id> -t my/first/topic -m "Hello NodeRED."Note:
iot-fr-par.scw.cloudmay vary, you find your endpoint on the Hub’s network page.
The command above contains the following elements:
-h: The endpoint or host of your IoT Hub. You require it to communicate with your hub.
-i: The device ID of your device. You can retrieve it from the Devices section of your hub.
-t: The thread to send your message to.
-m: The message containing the information you want to transmit.
Return to the NodeRED debug panel, the message should be displayed:.
Now you can create your own application to suit your needs. Check out the official NodeRED documentation for more information.
