IoT TS Aggregates Client for Python¶
The IoT TS Aggregates Service allows you to query aggregated time series data. Refer to IoT TS Aggregates for more information about the service.
Further implementation of the IOT TS Aggregate SDK library has been shown in a sample project that you can download and test in local or on mindsphere application. Please refer to this repository: mindsphere-python-sdk-examples
In the IoT context, assets are referred to as
entity and aspects as
Placeholders in the following samples are indicated by angular brackets
TS Aggregates Operations¶
Client name: AggregatesClient
Read Aggregated Time Series¶
This method returns aggregated data of a specific aspect of an asset from the specified time range. This feature is only available if aspect data is available within the specified time range.
A query can only return up to 200 aggregate intervals in one response.
Aggregates can only be created from up to 5,000 raw time series entries.
