Two-level aggregations

February 3, 2026

We are happy to announce that we have added support for two-level aggregations in the Explorer, chart, and single value widgets! This feature gives you more flexibility when working with grouped data by allowing you to apply a different aggregation function at the subject level than at the measurement level.

In many real-world scenarios, you don’t want to aggregate everything using the same function. Instead, you often need to calculate values per group (e.g. per turbine, customer, or location), and then combine those results into a single overall metric using a different aggregation function. Until now, the same aggregation function was used for both aggregating measurements and aggregating subjects.

With two-level aggregation, you can now:

1. Aggregate measurements per subject with one function (e.g. average), and then
2. Aggregate those subject results with another function (e.g. sum)

This makes it possible to answer questions like:

• What is the sum of average power usage across all my assets?
• What is the maximum average turbine active power per windpark?

All aggregation functions (min, max, sum, average, and count) are supported at both levels.
