Device List

The Device List page presents the total number of devices, online devices, offline devices, and inactive devices for the current application. You can configure a device. You can click a device to open the details page and view basic information, historical data, device shadow, and device tracking information. You can also modify some information.

The following table lists the statistics on each device status.

Device Status	Description	Refresh Period
Total	Total number of devices that have been registered with the IoT platform, including online, offline, and inactive devices.	Every minute
Online	A device is connected to the IoT platform. If a short-connection device (such as an NB-IoT device) reports no data for 49 consecutive hours (default) after connecting to the IoT platform, the IoT platform changes the device status from Online to Offline.
Offline	If a short-connection device (such as an NB-IoT device) reports no data for 49 consecutive hours (default) after connecting to the IoT platform, the IoT platform sets the device status to Offline. If a long-connection device (such as an MQTT device) is disconnected from the IoT platform, the device status is changed to Offline.
Inactive	A device has been registered but not connected to the IoT platform. The device activation procedure is described in Connecting a Device.

Configuration Delivery

Click at the row of a device to configure the device.

NOTE:

Before delivering the configuration, open the Product Models page, click Details of the product model to which the device belongs, and set Device Configuration to Supported on the Maintenance Capability Configuration tab page.

**Table 1** Parameters for configuring a device configuration delivery task
Parameter	Description
Task Name	Name of a configuration delivery task.
Execution Type	Task execution type. The value can be Now, Device online, or Custom. If the value is Custom, Executed Time must be set.
Executed Time	Time at which the task is executed. This parameter is valid only if Execution Type is set to Custom.
Retry Type	No: No retry is performed. Custom: Retry Attempts must be set.
Retry Attempts	This parameter is mandatory if Retry Type is set to Custom.
Retry Interval (s)	This parameter is mandatory if Retry Type is set to Custom.
Configuration File	You must upload the configuration file of the device. You can click Device Configuration File to download the configuration file that has been delivered last time, modify the file, and upload it. NOTE: If no configuration is delivered to the device before this operation, a message is displayed indicating that no resource was found when you click Device Configuration File. In this case, manually create a configuration file in user-defined mode. The items to be delivered must be consistent with the capabilities supported by the device (defined in the product model) and the configuration file must be in JSON format. An example configuration is as follows: { "sensitivity": "0", "dataReportInterval": "20" }
