- Remove pool stats/fetch-age from lifecycle sensor to avoid stale data under state-change filtering; add `next_api_poll` for transparency.
- Clean lifecycle calculator by dropping unused helpers/constants and delete the obsolete cache age test.
- Clarify lifecycle state is diagnostics-only in coordinator comments, keep state-change filtering in timer test, and retain quarter-hour precision notes in constants.
- Keep sensor core aligned with lifecycle state filtering.
Impact: Lifecycle sensor now exposes only state-relevant fields without recorder noise, next API poll is visible, and dead code/tests tied to removed attributes are gone.
Replace cache-based metrics with Pool as single source of truth:
- get_cache_age_minutes() → get_sensor_fetch_age_minutes() (from Pool)
- Remove get_cache_validity_status(), get_data_completeness_status()
- Add get_pool_stats() for comprehensive pool statistics
- Add has_tomorrow_data() using Pool as source
Attributes now show:
- sensor_intervals_count/expected/has_gaps (protected range)
- cache_intervals_total/limit/fill_percent/extra (entire pool)
- last_sensor_fetch, cache_oldest/newest_interval timestamps
- tomorrow_available based on Pool state
Impact: More accurate lifecycle status, consistent with Pool as source
of truth, cleaner diagnostic information.
- Introduced `get_intervals_for_day_offsets` helper to streamline access to price intervals for yesterday, today, and tomorrow.
- Updated various components to replace direct access to `priceInfo` with the new helper, ensuring a flat structure for price intervals.
- Adjusted calculations and data processing methods to accommodate the new data structure.
- Enhanced documentation to reflect changes in caching strategy and data structure.
Removed custom lifecycle callback push-update mechanism after confirming
it was redundant with Home Assistant's built-in DataUpdateCoordinator
pattern.
Root cause analysis showed HA's async_update_listeners() is called
synchronously (no await) immediately after _async_update_data() returns,
making separate lifecycle callbacks unnecessary.
Changes:
- coordinator/core.py: Removed lifecycle callback methods and notifications
- sensor/core.py: Removed lifecycle callback registration and cleanup
- sensor/attributes/lifecycle.py: Removed next_tomorrow_check attribute
- sensor/calculators/lifecycle.py: Removed get_next_tomorrow_check_time()
Impact: Simplified coordinator pattern, no user-visible changes. Standard
HA coordinator mechanism provides same immediate update guarantee without
custom callback complexity.
Cache validity now checks _last_coordinator_update (within 30min)
instead of _api_calls_today counter. Fixes false "stale" status
when coordinator runs every 15min but cache validation was only
checking API call counter.
Bug #1: Cache validity shows "stale" at 05:57 AM
Bug #2: Cache age calculation incorrect after midnight turnover
Bug #3: get_cache_validity inconsistent with cache_age sensor
Changes:
- Coordinator: Use _last_coordinator_update for cache validation
- Lifecycle: Extract cache validation to dedicated helper function
- Tests: 7 new tests covering midnight scenarios and edge cases
Impact: Cache validity sensor now accurately reflects coordinator
activity, not just explicit API calls. Correctly handles midnight
turnover without false "stale" status.
Add comprehensive data_lifecycle_status sensor showing real-time cache
vs fresh API data status with 6 states and 13+ detailed attributes.
Key features:
- 6 lifecycle states: cached, fresh, refreshing, searching_tomorrow,
turnover_pending, error
- Push-update system for instant state changes (refreshing→fresh→error)
- Quarter-hour polling for turnover_pending detection at 23:45
- Accurate next_api_poll prediction using Timer #1 offset tracking
- Tomorrow prediction with actual timer schedule (not fixed 13:00)
- 13+ formatted attributes: cache_age, data_completeness, api_calls_today,
next_api_poll, etc.
Implementation:
- sensor/calculators/lifecycle.py: New calculator with state logic
- sensor/attributes/lifecycle.py: Attribute builders with formatting
- coordinator/core.py: Lifecycle tracking + callback system (+16 lines)
- sensor/core.py: Push callback registration (+3 lines)
- coordinator/constants.py: Added to TIME_SENSITIVE_ENTITY_KEYS
- Translations: All 5 languages (de, en, nb, nl, sv)
Timing optimization:
- Extended turnover warning: 5min → 15min (catches 23:45 quarter boundary)
- No minute-timer needed: quarter-hour updates + push = optimal
- Push-updates: <1sec latency for refreshing/fresh/error states
- Timer offset tracking: Accurate tomorrow predictions
Removed obsolete sensors:
- data_timestamp (replaced by lifecycle attributes)
- price_forecast (never implemented, removed from definitions)
Impact: Users can monitor data freshness, API call patterns, cache age,
and understand integration behavior. Perfect for troubleshooting and
visibility into when data updates occur.
