    UpdateDescriptionRelease DateDocument
    Added the product-level key authentication featureThe IoT Hub platform supports product-level key authentication. In this mode, you only need to enable dynamic device registration and then burn the same configuration firmware (ProductID + ProductSecret) for all devices under the same product. In this way, the devices can get device certificates or keys through registration requests and then communicate with the platform.2019-05-30Product-Level Key Authentication
    Modified the processing logic of the `metadata` field of device shadow
  • The `metadata` field will not be delivered to devices by default.
  • When a device uses the `get shadow` method, the `metadata` bool tag can be used to specify whether to get the metadata.
  • The `metadata` field is added to `JSON Payload` in `Device Update Shadow`, which is optional. The default value is `false`.
  • The `metadata` field will still be returned when TencentCloud APIs are used to query device shadows.

    UpdateDescriptionRelease DateDocument
    Added the device grouping featureIoT Hub provides the multi-level device grouping feature to meet your needs for managing devices under different products by group in different business scenarios. You can:
  • Add, delete, modify, and query groups.
  • Add devices under different products or the same product to a group.
  • Manage multiple group levels.
  • Query the list of devices in a group.
  • 2019-04-05Device Grouping
    Added device payload logsTo meet your needs in connection debugging and business operations, the device payload log feature is added.
    You can get the message payload logs of device-cloud communication in the console or through APIs and search for them by device name, `RequestID`, and keyword. Payload logs in the last 15 days can be queried.
    2019-04-05Cloud Log
    Modified the strong verification logic of `Shadow Version`Strong verification of `Shadow Version` is modified to reduce the problems of shadow update failures due to inconsistent version numbers when you use device shadows. The current cloud-based processing logic is as follows:
  • For shadow update by TencentCloud APIs, a default value of the `Shadow Version` parameter is added. If the value is 0, IoT Hub will not check the shadow version number.
  • For shadow update by devices, if `Version` does not exist or `Version=0` is set, IoT Hub will not verify the shadow version.
  • 2019-04-05UpdateDeviceShadow

    March 2019

    UpdateDescriptionRelease DateDocument
    Added device exception log featuresThe device exception log collection and reporting feature is added to help you remotely locating device exceptions:
  • You can set four log levels (ERROR, WARN, INFO, and DEBUG) in the cloud and deliver them to devices for log collection and storage.
  • You can view device exception logs in the console or through APIs and search for them by time or keyword.
  • The device SDK provides a callback mechanism. If the communication is faulty, you can cache logs that cannot be reported temporarily based on the actual conditions and report cached logs after the communication recovers.
  • 2019-03-06Cloud Log

    January 2019

    UpdateDescriptionRelease DateDocument
    Added the gateway product connection featureIoT Hub supports the creation of gateway and subdevice products. You can bind a gateway product/device and the corresponding subproduct/subdevice, add the subproduct topic permission to the permission list of the gateway product, and then the gateway device can connect, disconnect, and send/receive messages on behalf of the subdevice over the MQTT protocol.2019-01-22Gateway Product Connection

    August 2018

    UpdateDescriptionRelease DateDocument
    Supported TencentCloud API 3.0 specificationsThe IoT Hub APIs are upgraded to v3.0. The new API documentation is more standardized and comprehensive. The unified parameter style, common error codes, and SDK/CLI version are highly consistent with the API documentation, providing a simple and fast user experience. The support for nearby access in all regions allows faster connection to Tencent Cloud services.2018-08-30API Documentation
    Supported binary data for the rule engineThe data supported by the rule engine is extended from JSON to binary format (the data format should be defined when the product is created), making it suitable for more scenarios such as private protocols and encrypted data. Data filtering and cleansing are not available for binary data forwarding.2018-08-20Device Connection Preparations
    Supported device key customization/modificationTo be compatible with device data from existing systems, device keys (Base64-encoded strings containing 4–64 characters) can be customized and modified.2018-08-20Device Connection Preparations
    Supported device category (tag) and remarks managementFor the management needs of tenants in the production environment, tags (for searching, filtering, and grouping) and remarks can be set for the device categories under the same product, so that the upper-layer applications can easily manage device assets better.2018-08-20Device Connection Preparations

    July 2018

    UpdateDescriptionRelease DateDocument
    Supported private deploymentFor the data privacy in government-oriented and business-oriented scenarios, IoT Hub supports private deployment. The feature points include the basic capabilities of the public edition, and the modules at the rule engine extension layer can also be privatized.2018-07-31-
    Supported cross-regional access and automated schedulingThe deployment of IoT Hub's access layer has expanded from one region (Guangzhou) to three regions (Guangzhou, Shanghai, and Beijing), making it easier for local connection by devices. In addition, based on QQ's network access node quality detection platform, the actual connection to IoT Hub is scheduled and intervened to improve fault detection and connection quality.2018-07-12-

    UpdateDescriptionRelease DateDocument
    Supported device monitoringIoT Hub provides monitoring capabilities for the device connection, message sending/receiving, device shadow, rule engine, and OTA features. You can view the monitoring data in the last 30 days, which helps you identify and troubleshoot business issues.2018-04-24Status Monitoring
    Supported data forwarding to CTSDBThe rule engine allows you to configure rules to forward eligible data reported by devices to CTSDB, and then your application server can read the data from CTSDB for processing. This takes advantage of CTSDB's high storage compression rate and aggregate display for massive amounts of data, effectively meeting the daily needs of devices for data storage, analysis, and visual display.2018-04-20Data Forwarding to CTSDB
    Refactored the consoleThe overall layout of the console is adjusted for an optimized user experience.2018-04-11-
    Supported data forwarding to CMQ topicsTencent Cloud Message Queue (CMQ) is a distributed message queue service that provides a reliable message-based async communication mechanism. It enables message receiving/sending among different applications deployed in a distributed manner (or different components of the same application) and stores the messages in reliable and valid CMQ queues to prevent message loss. It supports multi-process simultaneous read/write, so that message sending and receiving do not interfere with each other, eliminating the need for the applications or components to keep running.2018-04-11Data Forwarding to CMQ Topic

    March 2018

    UpdateDescriptionRelease DateDocument
    Supported data forwarding to CKafkaThe rule engine allows you to configure rules to forward eligible data reported by devices to CKafka, and then your application server can read the data from CKafka for processing. This takes advantage of CKafka's high throughput to create a highly available message linkage.2018-03-13Data Forwarding to CKafka
    Supported firmware updateDevice firmware update (aka OTA) is an important part of the IoT Hub service. When a device has new features available or vulnerabilities that need to be fixed, firmware update can be quickly performed for it using the OTA service.2018-03-13Firmware Update

    Supported data forwarding to third-party servicesWhen forwarding a message field extracted through a rule to a third-party service, you can customize how to process the data. This is the most flexible way for you to process the message. Please note that the third-party service must be HTTP-based. To configure forwarding to a third-party service, you need to provide a URL and port number supporting HTTP.2018-02-08Data Forwarding to Third-Party Service
