Add calculate_coefficient_of_variation() as central utility function: - CV = (std_dev / mean) * 100 as standardized volatility measure - calculate_volatility_with_cv() returns both level and numeric CV - Volatility sensors now expose CV in attributes for transparency Used as foundation for quality gates, adaptive smoothing, and period statistics. Impact: Volatility sensors show numeric CV percentage alongside categorical level, enabling users to see exact price variation.

Pure data transformation utilities for Tibber Prices integration.
|
|
|
|
This package contains stateless, pure functions for data processing:
|
|
- Time-window calculations (trailing/leading averages, min/max)
|
|
- Price enrichment (differences, volatility, rating levels)
|
|
- Statistical analysis (aggregation, trends)
|
|
|
|
These functions operate on raw data structures (dicts, lists) and do NOT depend on:
|
|
- Home Assistant entities or state management
|
|
- Configuration entries or coordinators
|
|
- Translation systems or UI-specific logic
|
|
|
|
For entity-specific utilities (icons, colors, attributes), see entity_utils/ package.
