Azure IoT Device Node-RED node
The Azure IoT Device Node-RED node is a node that can be used to connect Node-RED to the Azure IoT platform. It can connect to Azure IoT Hub, Azure IoT Central, and use Azure IoT Edge as a transparant gateway. The node has been created to support the different attestation methods (SAS, X.509) as well as use Azure Device Provisioning Service. The node has been developed using the Azure IoT Node.js SDK.
The Azure IoT Device node represents a single device on the Azure IoT platform.
NB: It is our assumption that you have a basic understanding of Node-RED and the Azure IoT platform.
Deploy the Azure Device node
In the deploy document we describe how to deploy the node to Node-RED.
Configure an Azure IoT Device node
In the configure document we describe how to setup an individual Azure IoT Device node.
Use an Azure IoT Device node
In the use document we describe how to use the Azure IoT Device node to interact with the Azure IoT platform.
- sending telemetry
- receiving and responding to commands
- receiving desired properties
- updating reported properties
- receiving C2D messages
Resilience
The node is developed to resist network loss. If there is no connectivity, the node will try to re-establish a device connection based on the set retry interval. The node doesn't store and forward. All message and properties sent during a loss of connectivity, will be lost.
