Request Format

POST https://{apigw-address}/tsdb-service/v2.1/electric-power

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 organization ID>>

Request Parameters (Body)

Name	Mandatory/Optional	Data Type	Description
modelId	Optional	String	The model ID. How to get model ID>>
assetIds	Mandatory	String	The asset ID. Supports the query of multiple asset IDs, separated by commas. How to get asset ID>>
pointIdsWithLogic	Mandatory	String	The aggregation logic with measurement point ID. The supported aggregation calculation methods include count, avg, sum, max, min, first, and last. The time range for the aggregation query is [startTime, endTime), that is, the aggregation operand contains the data at the time of startTime, but does not contain the data at the time of endTime. Format: Function(pointId), supporting multiple measurement points e.g. sum(pointId1),sum(pointId2). How to get measurement point ID>>
interval	Mandatory	Integer	The time interval for the aggregation algorithm to work. The effective value is 0-1440, calculated in minutes. If the interval value is 0, the measurement point has no aggregation logic; if the interval value is greater than 0, the measurement point must have the aggregation logic.
startTime	Mandatory	String	The start time of the sampling data, where both UTC and local time formats are supported. For UTC time format, the application will query all the asset data by the unified start timestamp and end timestamp. Timezone information is required for the UTC time format: 2019-06-01T00:00:00+08:00. For local time format, the application will query the asset data by the local time of where the device is located. Its format is: YYYY-MM-DD HH:MM:SS.
endTime	Mandatory	String	The end time of the sampling data. Its format must be consistent with startTime.
pageSize	Optional	Integer	The upper limit of the returned records in a single page for a single measurement point of a single device, which is 1,000 by default.
localTimeAccuracy	Optional	Boolean	true = query returns data with millisecond time stamp false (default) = query returns data without millisecond time stamp
localTimeFormat	Optional	Integer	Specify whether the local time value includes time zone information of devices. 0 (default): without time zone information; 1: with time zone information.
itemFormat	Optional	Integer	Specify the displaying format of the returned device data. Available options are 0, 1, and 2. For the example of each displaying format, see Item Format Example>>

Response Parameters

Name	Data Type	Description
data	List<JSONObject>	The list of asset data. The data returned for a single point of a single device is sorted by the data time stamp in ascending order. For more information, see items

items

Sample

{
       "assetId": "yourAssetId",
       "timestamp": 1560249300000,
       "sum(yourPointId)": 4.246,
       "localtime": "2019-06-11 18:35:00"
}

Parameters

Name	Data Type	Description
assetId	String	The asset ID.
pointIdsWithLogic	Double	This parameter is a variable, representing the identifier and data of the measurement point (with or without aggregation logic). The data here is the daily aggregation of the sum of power consumption/production data.
timestamp	Long	The data timestamp (UNIX time, accurate to the second).
localtime	String	The data timestamp in local time format (accurate to the second). The value of the localTimeFormat parameter determines whether the local time value includes the time zone information.
