Get Asset DI Data

Get the status (DI) data of a specified device within a certain period.

The API captures the state data for a particular asset over a period of time and returns only data that reflects changes in the state of the asset. For example, the raw data within a period is given as follows:

Time       Status
10:01:14    0
10:01:30    0
10:03:45    0
10:12:23    1
10:13:34    0
10:15:24    1
10:17:25    1

The returned results are given as follows:

Time       Status
10:01:14    0
10:12:23    1
10:13:34    0
10:15:24    1

Note

If there is no DI data at the start time of the request, then trace back the last state value within the latest 30 days since the start time. The data is returned with the timestamp of the request start time.

Request Parameters (URI)

Name

Location (Path/Query)

Required or Not

Data Type

Description

orgId

Query

true

String

Organization ID which the asset belongs to. How to get orgId>>

modelId

Query

false

String

Model ID which the asset belongs to. How to get modelID>>

assetIds

Query

true

String

Asset ID, which supports querying multiple assets; multiple asset IDs are separated by commas. How to get assetId>>

measurepoints

Query

true

String

Asset measurement point. It is supported to query multiple measurement points, and all the measurement points are separated by commas; the upper limit for query is 3000 (Number of devices *Number of measurement points). How to get pointId>>

startTime

Query

true

String

Time of start sampling data, where UTC time format and local time format are supported. The local time format is YYYY-MM-DD HH:MM:SS. In case of local time format, the application queries the assets by the local time of the location where the device is. Timezone information is required for UTC time format, e.g. 2019-06-01T00:00:00+08:00; in case of UTC time format, the application queries all the assets by the unified start timestamp and end timestamp.

endTime

Query

true

String

Time to stop sampling data. Its format must be consistent with the start time

accessKey

Query

false

String

Service account of the application. The application authenticates with accessKey to obtain the data that it is authorized to access. How to get accessKey>>

localTimeAccuracy

Query

false

Boolean

Specify whether query returns data with millisecond time stamp.

autoInterpolate

Query

false

Boolean

Specify wheter to query the lastest status data in the past if no data is found at the query start time.

Response Parameters

Name

Data Type

Description

items

List<Object>

List of asset data. The data returned for a single point of a single device is sorted by time in ascending order. Parameters are stored in the Object struct. See items.
