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”, and “disable”
