expression

Optional

String

The query expression, which supports sql-like query. The fields that are supported for query include the below.

  • deviceAttributes: supports operators “=”, “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 operators “=”, “!=”, “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: supports operators “=”, “!=”, and “in”.

  • productKey , deviceKey , and assetId: support operators “=” and “in”.

  • productType: supports operator “=”, valid values are: “Device” and “Gateway”.

  • firmwareVersion: supports 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 operators “=” and “in”, valid values are: “inactive”, “online”, “offline”, “disable”, and “mirror”.

populateLastUpdateInfo

Optional

Boolean

  • true: Returns measurepointLastUpdate, eventLastUpdate, attributeLastUpdate, and featureLastUpdate.

  • false (default): Does not return measurepointLastUpdate, eventLastUpdate, attributeLastUpdate, and featureLastUpdate.
