    View the devices of a product

    Select a product from the drop-down list in the upper-left corner of the Devices page.

    You can view the status of each device.

    • Inactive: The device is not connected to IoT Platform.

      You can configure the device, connect the device to IoT Platform, and then activate the device. For information about how to configure devices, see Download Link SDK.

    • Online: The device is activated and connected to IoT Platform.

    • Offline: The device is activated and disconnected from IoT Platform.

    • Disabled: The device is disabled.

    For information about how to connect or disconnect devices, see Connect and disconnect devices.

    Search for a device

    Enter a device name, alias, or tag to search for a device. Fuzzy match is supported.

    You can also click the Advanced Search tab to search for a device. For more information, see Advanced search.

    View detailed information about a device

    Find the device whose information you want to view and click View in the Actions column. For more information, see View detailed information about a device.

    Delete a device

    Find the device that you want to delete and click Delete in the Actions column. For more information, see Delete a device.

    Important

    After you delete a device, the device certificate becomes invalid and the data of the device is deleted from IoT Platform.

    Disable and enable a device

    Click 关闭状态 to enable a device or click 启用状态 to disable a device. For more information, see Disable and enable a device.

    • If you disable a device, the device is not allowed to connect to IoT Platform.

Task

Procedure

View basic information about a device

View basic information about the device, including the device certificate information, firmware information, Message Queuing Telemetry Transport (MQTT) connection parameters, extended information, and tags.

  • You can use a self-developed MQTT tool to connect the device to IoT Platform and authenticate the device by using the unique-certificate-per-device method. In this case, you can view the following MQTT connection parameters on the Device Information tab: username, passwd, clientId, mqttHostUrl, and port. For more information, see How do I obtain MQTT parameters for verification?

  • If you connect the device to IoT Platform and authenticate the device by using the preregistration-free unique-certificate-per-product verification method, you can view the ClientID of the device in the MQTT Connection Parameters field on the Device Information tab. You cannot view the DeviceToken parameter in the IoT Platform console because this information must be stored on the device.

For more information about MQTT connection parameters, see Establish MQTT connections over TCP.

View information about topics

Click the Topic List tab to view information about topics. If the subscription to topics feature is enabled for the device and the device is connected to IoT Platform, the topics to which the device subscribes are displayed on the tab. You can also search for specific topics.

For more information, see Topics.

View Thing Specification Language (TSL) data

On the TSL Data tab, you can perform the following operations:

  • Click the Status tab to view the current values, data records, and desired values of properties that are submitted by the device.

    TSL properties are sorted in alphabetical order based on the first letter of each TSL property name.

    In the upper-right corner of a TSL model card, click View Log to go to the Cloud run log tab of the page that appears. You can also go to this page by choosing Maintenance > Device Log in the left-side navigation pane. You can view logs of the TSL model in the previous seven days on this page.

  • Click the Events tab to view the event records that are submitted by the device.

  • Click the Invoke Service tab to view the service call records of the device.

View device shadows

Click the Device Shadow tab to view information about device shadows and update the status of the device shadows. For more information, see Overview of device shadows.

View device files

Click the Manage Files tab to manage the files that are uploaded from the device to IoT Platform. For more information, see File management.

View device logs

Click the Device Log tab, and then click View to view the IoT Platform logs. If Device local log reporting is enabled on the Device Information tab, you can also view the local logs of the device. For more information, see IoT Platform logs and Local device logs.

Perform online debugging

Click the Online Debug tab, and then click View to perform debugging on the page that appears. You can also go to this page by choosing Maintenance > Online Debug in the left-side navigation pane. For more information, see Online debugging.

View sub-devices

Click the Sub-device Management tab to view or add sub-devices. This task is available only on the device details pages of gateways. For more information, see Gateways and sub-devices.

View device groups

Click the Groups tab to view the groups to which the device belongs or add the device to an existing group. For more information, see Device groups.
