Overview

Device access

Native protocol access

You can connect devices to the platform using MQTT, CoAP, LwM2M, and HTTPS protocols.

Device SDK series

You can use IoT Device SDK and IoT Device SDK Tiny in languages such as C and Java.

Industry protocol access

You can connect devices to the platform through edge gateways using Modbus and OPC Unified Architecture (OPC UA) and using industry protocols based on plug-ins.

Device access authentication

You can use authentication modes such as one-device-one-secret and X.509 certificates.

Device management

Device lifecycle management

You can add, delete, modify, and query devices, manage device status, freeze and unfreeze devices, and manage child devices.

Device groups and tags

You can group devices or add tags to them. For details, see Groups and Tags.

Product models

You can define a product model (profile) for devices.

Device shadow

You can query and set shadow data. For details, see Device Shadow.

OTA upgrade

You can upgrade the software and firmware of devices. For details, see OTA Upgrade.

Device file upload

You can upload files to Object Storage Service (OBS) and request files from the cloud. For details, see File Upload.

Batch device operations

You can perform batch operations on devices, including Creating Devices in Batches, Upgrading Software and Firmware in Batches, and Delivering Commands in Batches.

Message communications

Bidirectional transparent transmission

You can push device messages to applications using HTTP and AMQP. Applications can deliver messages to devices asynchronously.

Product model topic communications

Applications and devices communicate with each other based on the properties, commands, and events defined in the product model in a decoupled mode.

Custom topic communications

You can customize topics for bidirectional message communications.

Data parsing and conversion

You can develop codecs online to parse and convert device data.

Command delivery

You can deliver commands to online devices in synchronous mode. In NB-IoT scenarios, commands can be delivered in asynchronous mode. For details, see Command Delivery.

Rules

Data forwarding

You can forward data to cloud platform Kafka, OBS, and Data Ingestion Service (DIS). For details, see Rules.

Device linkage

You can create rules for device linkage control. For details, see Rules.

Data forwarding

You can forward data reported by devices to applications through HTTP or AMQP.

Monitoring and O&M

Logging

You can trace messages. The platform integrates with Log Tank Service (LTS) for log analysis and integrates with Cloud Trace Service (CTS) for log audit. For details, see Monitoring and O&M.

Alarm reporting

You can manage alarms. The platform provides notifications of system alarms (such as threshold alarms) and alarms triggered by device rules by integrating with Application Operations Management (AOM). For details, see Alarms.

Metric monitoring

You can monitor tenant-level service metrics (such as device status, commands, subscription and push, and message transfer). The platform provides monitoring reports by integrating with AOM. For details, see Reports.
