RegisterDevice

Registers a device under a product.

Usage notes

If you call this operation to register a device under a product, the device is added to the product in the IoT Platform console. After the device is registered, IoT Platform issues the IotId parameter to the device. This parameter is a globally unique identifier (GUID) of the device. To perform operations on a device, you must use the IotId parameter to identify the device.

You can also use a combination of the ProductKey and DeviceName parameters to identify a device. A ProductKey is issued by IoT Platform to a product when you create the product. A DeviceName is specified or randomly generated when you create a device. The IotId parameter has a higher priority than a combination of the ProductKey and DeviceName parameters.

For information about how to register multiple devices under a product at the same time, see [BatchRegisterDeviceWithApplyId]

Request parameters

Parameter	Type	Required	Example	Description
Action	String	Yes	RegisterDevice	The operation that you want to perform. Set the value to RegisterDevice.
ProductKey	String	Yes	a1BwAGV****	The ProductKey of the product to which the device belongs. A ProductKey is a GUID that is issued by IoT Platform to a product. You can use the IoT Platform console or call the QueryProductList operation to view the information about all products within the current account.
DeviceName	String	No	light	The DeviceName of the device. The name must be 4 to 32 characters in length, and can contain letters, digits, hyphens (-), underscores (_), at signs (@), periods (.), and colons (😃. You can use a combination of the DeviceName and ProductKey parameters to identify a device. Note If you do not specify this parameter, IoT Platform randomly generates a DeviceName.
DevEui	String	No	e8SDdgeIlk3nED****	The DevEUI of the LoRaWAN device. This parameter is required when you create a LoRaWAN device.
Nickname	String	No	Campus light	The alias of the device. The alias must be 4 to 64 characters in length, and can contain letters, digits, and underscores (_). Note If you do not specify this parameter, IoT Platform does not generate an alias for the device.
PinCode	String	No	DIe80dfeg*****	The PIN code of the LoRaWAN device. This parameter is used to verify the DevEUI. When you create a LoRaWAN device, set LoraNodeType to ALIYUNDEFINED. This parameter is required.
JoinEui	String	No	Ede4tde8erth****	The JoinEUI of the LoRaWAN device. When you create a LoRaWAN device, set LoraNodeType to USERDEFINED. This parameter is required.
AppKey	String	No	674f***	The AppKey of the LoRaWAN device. When you create a LoRaWAN device, set LoraNodeType to USERDEFINED. This parameter is required.
LoraNodeType	String	No	ALIYUNDEFINED	The type of the LoRaWAN device. Valid values: - ALIYUNDEFINED: The device is issued by Alibaba Cloud. You must specify DevEui and PinCode. - USERDEFINED: The device is user-defined. You must specify DevEui, JoinEui, and AppKey.

In addition to the preceding operation-specific request parameters, you must specify common request parameters when you call this operation. For more information, see Common request parameters.
