After you create a device in IoT Platform, you can manage it in the IoT Platform console.

Prerequisites

A device is created in the IoT Platform console. For more information, see Create a device.

View devices

Log on to the IoT Platform console.
On the Overview page, select an environment, find the instance that you want to manage, and click the instance ID or instance name.
Important This step is required only if Enterprise Edition instances are available. If the Enterprise Edition instances are unavailable in the region that you selected, skip this step. For information about supported regions and instances, see Overview.

Operation	Procedure
View the devices of a product	Select a product from the drop-down list in the upper-left corner of the page. You can view the status of each device: Inactive: The device is not connected to IoT Platform. You can develop the device, connect the device to IoT Platform, and then activate the device. For more information, see Download device SDKs. 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 more information, 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 click the Advanced Search tab and search for a device by using query statements. 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 a device is deleted, the device certificate becomes invalid and the data about this device is deleted from IoT Platform.
Disable and enable a device	Click to disable a device, or click to enable 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. If you enable a device, the device is allowed to connect to IoT Platform.

View detailed information about a device

In the device list, find the device whose information you want to view and click View in the Actions column. The device details page appears.


Operation	Procedure
View device information	View the basic information about the device, including the device certificate information, firmware information, 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 authentication? If you connect the device to IoT Platform and authenticate the device by using the pre-registration unique-certificate-per-product verification method, you can view the ClientID of the device in MQTT Connection Parameters on the Device Information tab. However, 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 the information of topics	Click the Topic List tab to view the information of topics. If the development process has been complete for the device and the device has been connected to IoT Platform, the topics it subscribes to are listed on this page. For more information, see Topics.
View the information of TSL models	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. 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 of the device shadows and update the status of the shadows. For more information, see Overview of device shadows.
View device files	Click the File Management 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 (available only for gateway devices)	Click the Sub-device Management tab to view or add sub-devices. For more information, see Manage 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.
