Request Parameters (URI)

Name Location (Path/Query) Mandatory/Optional Data Type Description
orgId Query Mandatory String The organization ID which the asset belongs to. How to get orgId>>

Request Parameters (Body)

Name Mandatory/Optional Data Type Description
gateway Mandatory DeviceIdentfier Struct Information of the gateway the sub-devices are under. For details, see DeviceIdentfier Struct.
expression Optional String

The query expression, which supports sql-like query. The fields that are supported for query include: modelId , deviceAttributes , deviceTags, productKey, deviceKey, assetId, deviceName, and status.

  • deviceAttributes: supports arithmetic operator “=”, “exists”, “not exists”, and “in”. To use this parameter in a query, you need to use the format deviceAttributes.attributeId to specify an attribute. For example, “deviceAttributes.temperature”=35.5.
  • deviceTags: supports arithmetic operator “=”, “exists”, “not exists”, and “in”. To use this parameter in a query, you need to use the format deviceTags.keyName to specify the key of a tag. For example, “deviceTags.Region” = “China”
  • modelId , productKey , deviceKey , and assetId : support arithmetic operators “=” and “in”
  • deviceName: supports fuzzy inquiry of the specified language:
    • deviceName like ‘xxx’: fuzzy inquiry of the default name, Chinese name, and English name
    • deviceName.default like ‘xxx’: fuzzy inquiry of the default name
    • deviceName.zh_CN like ‘xxx’: fuzzy inquiry of the Chinese name. If no Chinese name exists, fuzzy inquiry of default name
    • deviceName.en_US like ‘xxx’: fuzzy inquiry of the English name. If no English name exists, fuzzy inquiry of default name
  • status: supports arithmetic operator “=”, valid values are: “inactive”, “online”, “offline”, “disable”, and “mirror”

For details, see Pagination Request Struct>>
projection Optional Projection Struct Enables you to crop the data result set returned in the request if needed. Only the specified fields will be returned in the data result set if this parameter is used. Otherwise all fields are returned. For more details, see How does projection crop the result set>>

Response Parameters

Name Data Type Description
data Array of Device Structs A list of the devices returned. For the details of a Device Struct, see Device Struct.

Error Codes

Code Message Description
11738 Not Gateway The device specified in gateway is not a gateway.
