Queries the status of a device.

Limits

Each Alibaba Cloud account can run a maximum of 500 queries per second (QPS).

Note RAM users of an Alibaba Cloud account share the quota of the account.

Debugging

Alibaba Cloud provides OpenAPI Explorer to simplify API usage. OpenAPI Explorer automatically calculates the signature value. For your convenience, we recommend that you call this operation in OpenAPI Explorer. OpenAPI Explorer dynamically generates the sample code of the operation for different SDKs.

Request parameters

Parameter Type Required Example Description
Action String Yes GetDeviceStatus

The operation that you want to perform. Set the value to GetDeviceStatus.

IotInstanceId String No iot_instc_pu****_c*-v64********

The ID of the instance. You can view the instance ID on the Overview page in the IoT Platform console.

Notice
  • If your instance has an ID, you must configure this parameter. If you do not set this parameter, the call fails.
  • If your instance has no Overview page or ID, you do not need to set this parameter.

For more information, see Overview.

ProductKey String No a1BwAGV****

The ProductKey of the product to which the device belongs.

Note If you specify this parameter, you must also specify the DeviceName parameter.
DeviceName String No light

The DeviceName of the device.

Note If you specify this parameter, you must also specify the ProductKey parameter.
IotId String No Q7uOhVRdZRRlDnTLv****00100

The ID of the device. The ID is a unique identifier that is issued by IoT Platform to the device.

Note If you specify this parameter, you do not need to specify ProductKey or DeviceName. The IotId parameter specifies a globally unique identifier (GUID) of the device, which corresponds to a combination of ProductKey and DeviceName. If you specify both IotId and the combination of ProductKey and DeviceName, IotId takes precedence.

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.
