In this way, the devices can get device certificates or keys through registration requests and then communicate with the platform. | 2019-05-30 | |
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. | 2019-05-30 |
April 2019
Update | Description | Release Date | Document |
Added the device grouping feature | IoT 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. | 2019-04-05 | |
Added device payload logs | To 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. | 2019-04-05 | |
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. | 2019-04-05 | UpdateDeviceShadow |
March 2019
Update | Description | Release Date | Document |
Added device exception log features | The 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. | 2019-03-06 |
January 2019
Update | Description | Release Date | Document |
Added the gateway product connection feature | IoT 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. | 2019-01-22 |
August 2018
Update | Description | Release Date | Document |

The support for nearby access in all regions allows faster connection to Tencent Cloud services. | 2018-08-30 | API Documentation |
Supported binary data for the rule engine | The 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. | 2018-08-20 | |
Supported device key customization/modification | To be compatible with device data from existing systems, device keys (Base64-encoded strings containing 4–64 characters) can be customized and modified. | 2018-08-20 | |
Supported device category (tag) and remarks management | For 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. | 2018-08-20 |

Supported data forwarding to CTSDB | The 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. | 2018-04-20 | |
Refactored the console | The overall layout of the console is adjusted for an optimized user experience. | 2018-04-11 | - |
Supported data forwarding to CMQ topics | Tencent 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. | 2018-04-11 |
March 2018
Update | Description | Release Date | Document |
Supported data forwarding to CKafka | The 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.
