Using GET Method

Request Format

GET https://{apigw-address}/tsdb-service/v2.0/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>>
modelId Query Optional String The model ID. How to get model ID>>
assetIds Query Mandatory String The asset ID. Supports the query of multiple asset IDs, separated by commas. How to get asset ID>>
measurepointsWithLogic Query 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 Query 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 Query 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 Query Mandatory String The end time of the sampling data. Its format must be consistent with startTime.
pageSize Query 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.
accessKey Query Optional String The service account for authentication purposes. How to get the accessKey>>
localTimeAccuracy Query Optional Boolean
  • true = query returns data with millisecond time stamp
  • false (default) = query returns data without millisecond time stamp

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": "6/11/2019 6:35:00 PM"

}
Parameters
Name Data Type Description
pointIdWithLogic 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 sonsumption/production data.
assetId String The asset ID.
timestamp Long The data timestamp (UNIX time, accurate to the second).
localtime String The data timestamp in local time format (accurate to the second). If UTC time format is used when specifying the statTime and endtime, this value will be null.
