Get Asset DI Data

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

The API captures the state of 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 as follows:

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

Note

The status data of specific assets may be represented by other integers. If there is no DI data at the start time of the request, it will trace back the last state value within the last 30 days from the start time. The data is returned with the timestamp of the request start time.

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.

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

autoInterpolate

Query

Optional

Boolean

  • true = query the latest status data in the past if no data is found at the query start time

  • false (default) = do not query the latest status data in the past if no data is found at the query start time
