Pushing Device Registration Notifications

Typical Scenario

After an NA subscribes to device registration notifications (the notification type is deviceAdded) on the IoT platform, the IoT platform sends a notification message to the NA when the NA registers a device on the IoT platform by calling the API for registering a directly connected device.

API Function

This API is used by the IoT platform to push notification messages to an NA that has subscribed to device registration notifications.

Note

When Subscribing to Service Data of the IoT Platform, an NA must subscribe to the specified callback address in the API description. The server and port in the callback address are the public IP address and specified port of the NA server.
An NA receives the content of a push message by inheriting the PushMessageReceiver class and rewriting the callback API.
If the callback address is not the address of the NA, the NA must implement the original callback API. For details on the API content, see Message Push in the Huawei IoT Platform Northbound API Reference.

API Description

Callback URL	https://server:port/v1.0.0/messageReceiver
Callback API	def handleDeviceAdded(self):
Class	PushMessageReceiver

Parameter Description

request.json

Parameter	Mandatory or Optional	Type	Location	Description
request.json	Mandatory	NotifyDeviceAddedDTO	body	For details, see NotifyDeviceAddedDTO structure.

NotifyDeviceAddedDTO structure

Parameter	Mandatory or Optional	Type	Location	Description
notifyType	Mandatory	String	body	Indicates the notification type. The value is deviceAdded.
deviceId	Mandatory	String	body	Uniquely identifies a device.
gatewayId	Optional	String	body	Uniquely identifies a gateway.
nodeType	Mandatory	String	body	Specifies the type of a device. ENDPOINT GATEWAY UNKNOWN
deviceInfo	Mandatory	DeviceInfo	body	Indicates information about the device. For details, see DeviceInfo structure.

DeviceInfo structure

Parameter	Mandatory or Optional	Type	Location	Description
nodeId	Mandatory	String(256)	body	Uniquely identifies the device. Generally, the MAC address, serial number, or IMEI is used as the node ID. NOTE: When the IMEI is used as the node ID, the node ID varies depending on the chip provided by the manufacturer. The unique identifier of a Qualcomm chip is urn:imei:xxxx, where xxxx is the IMEI. The unique identifier of a HiSilicon chip is the IMEI. For details on the unique identifiers of chipsets provided by other manufacturers, contact the module manufacturers.
name	Optional	String(256)	body	Indicates the device name.
description	Optional	String(2048)	body	Indicates the device description.
manufacturerId	Optional	String(256)	body	Uniquely identifies a manufacturer.
manufacturerName	Optional	String(256)	body	Indicates the manufacturer name.
mac	Optional	String(256)	body	Indicates the MAC address of the device.
location	Optional	String(2048)	body	Indicates the device location.
deviceType	Optional	String(256)	body	Indicates the device type. The upper camel case is used, for example, MultiSensor, ContactSensor, and CameraGateway.
model	Optional	String(256)	body	Indicates the device model.
swVersion	Optional	String(256)	body	Indicates the software version of the device. In Z-Wave, the format is major version.minor version, for example, 1.1.
fwVersion	Optional	String(256)	body	Indicates the firmware version of the device.
hwVersion	Optional	String(256)	body	Indicates the hardware version of the device.
protocolType	Optional	String(256)	body	Indicates the protocol type used by the device. The value options are CoAP, huaweiM2M, Z-Wave, ONVIF, WPS, Hue, WiFi, J808, Gateway, ZigBee, and LWM2M.
bridgeId	Optional	String(256)	body	Identifies the bridge through which the device accesses the IoT platform.
status	Optional	String	body	Indicates whether the device is online. The value options are ONLINE, OFFLINE, INBOX, and ABNORMAL.
statusDetail	Optional	String(256)	body	Indicates status details of the device. The value of this parameter varies with the value of status. For details, see status and statusDetail.
mute	Optional	String	body	Indicates whether the device is in the frozen state. Based on the value of this parameter, the IoT platform determines whether to manage and store data reported by the device. TRUE: The device is in the frozen state. FALSE: The device is not in the frozen state.
supportedSecurity	Optional	String	body	Indicates whether the security mode is supported. TRUE: The security mode is supported. FALSE: The security mode is not supported.
isSecurity	Optional	String	body	Indicates whether the security mode is enabled. TRUE: The security mode is enabled. FALSE: The security mode is disabled.
signalStrength	Optional	String(256)	body	Indicates the signal strength of the device.
sigVersion	Optional	String(256)	body	Indicates the SIG version of the device.
serialNumber	Optional	String(256)	body	Indicates the serial number of the device.
batteryLevel	Optional	String(256)	body	Indicates the battery level of the device.

status and statusDetail

status	statusDetail
OFFLINE	NONE CONFIGURATION_PENDING
ONLINE	NONE COMMUNICATION_ERROR CONFIGURATION_ERROR BRIDGE_OFFLINE FIRMWARE_UPDATING DUTY_CYCLE NOT_ACTIVE

NOTE:

When the device status information is reported to the IoT platform, status and statusDetail must be included. It is recommended that statusDetail be used only for display but not for logical judgment.

Response Parameters

Status Code: 200 OK
