Keep raw Tibber API levels for best/peak period filtering while leaving smoothed levels in priceInfo for display-oriented sensors. Also make relaxation retry each flex step with the configured level filter before falling back to level_filter="any", and add regression tests for both paths.
Impact: Best-price periods no longer extend into expensive intervals because of level smoothing, and adjacent best/peak windows stay separated as expected.
_resolve_time_with_day_offset() was calling dt_util.now() internally
instead of using the injected now parameter. This caused incorrect date
calculations in tests and any caller that passes a specific reference time.
Also add missing price_rank_* sensor keys to TIME_SENSITIVE_ENTITY_KEYS
in coordinator/constants.py so quarter-hour refresh is registered for all
11 price rank sensors (current/next/previous interval and hour variants).
Rename dt as dt_utils → dt as dt_util (ICN001) across 11 files to follow
the project-wide import alias convention. Apply ruff auto-fixes for import
ordering and collapsing single-item imports throughout the codebase.
Released-Bug: no
Changed from centralized main+subentry coordinator pattern to independent
coordinators per home. Each config entry now manages its own home data
with its own API client and access token.
Architecture changes:
- API Client: async_get_price_info() changed from home_ids: set[str] to home_id: str
* Removed GraphQL alias pattern (home0, home1, ...)
* Single-home query structure without aliasing
* Simplified response parsing (viewer.home instead of viewer.home0)
- Coordinator: Removed main/subentry distinction
* Deleted is_main_entry() and _has_existing_main_coordinator()
* Each coordinator fetches its own data independently
* Removed _find_main_coordinator() and _get_configured_home_ids()
* Simplified _async_update_data() - no subentry logic
* Added _home_id instance variable from config_entry.data
- __init__.py: New _get_access_token() helper
* Handles token retrieval for both parent and subentries
* Subentries find parent entry to get shared access token
* Creates single API client instance per coordinator
- Data structures: Flat single-home format
* Old: {"homes": {home_id: {"price_info": [...]}}}
* New: {"home_id": str, "price_info": [...], "currency": str}
* Attribute name: "periods" → "pricePeriods" (consistent with priceInfo)
- helpers.py: Removed get_configured_home_ids() (no longer needed)
* parse_all_timestamps() updated for single-home structure
Impact: Each home operates independently with its own lifecycle tracking,
caching, and period calculations. Simpler architecture, easier debugging,
better isolation between homes.
Fixes bug where lifecycle sensor attributes (data_completeness, tomorrow_available)
didn't update after tomorrow data was successfully fetched from API.
Root cause: DataTransformer had cached transformation data but no mechanism to detect
when source API data changed (only checked config and midnight turnover).
Changes:
- coordinator/data_transformation.py: Track source_data_timestamp and invalidate cache
when timestamp changes (detects new API data arrival)
- coordinator/data_transformation.py: Integrate period calculation into DataTransformer
(calculate_periods_fn parameter) for complete single-layer caching
- coordinator/core.py: Remove duplicate transformation cache (_cached_transformed_data,
_last_transformation_config), simplify _transform_data_for_*() to direct delegation
- tests/test_tomorrow_data_refresh.py: Add 3 regression tests for cache invalidation
(new timestamp, config change behavior, cache preservation)
Impact: Lifecycle sensor attributes now update correctly when new API data arrives.
Reduced code by ~40 lines in coordinator, consolidated caching to single layer.
All 350 tests passing.
