- Secure device provisioning (X.509, SAS keys)
- Per-device authentication and access control
- Built‑in device management
- Message routing & integration with Azure services
Quick Start
Follow these steps to create an IoT Hub and connect a test device.
az group create --name MyIoTHubRG --location eastus
az iot hub create --resource-group MyIoTHubRG --name MyIoTHub --sku S1
az iot hub device-identity create --hub-name MyIoTHub --device-id test-device
az iot hub device-twin show --hub-name MyIoTHub --device-id test-deviceUse the connection string from the last command to configure your device SDK.
Sample Code (Node.js)
const { Client } = require('azure-iot-device');
const { Mqtt } = require('azure-iot-device-mqtt');
const connectionString = 'HostName=MyIoTHub.azure-devices.net;DeviceId=test-device;SharedAccessKey=...';
const client = Client.fromConnectionString(connectionString, Mqtt);
client.open()
.then(() => client.sendEvent({ temperature: 23.5 }))
.then(() => console.log('Message sent'))
.catch(err => console.error('Error: ', err));
