a4ad506e01 feat(sensor): use dynamic precision for price rounding and display
Add get_display_precision() to const.py returning DISPLAY_PRECISION_SUBUNIT (2)
or DISPLAY_PRECISION_BASE (4) based on config. Replace hardcoded round(..., 2)
with get_display_precision() in all calculators and attribute builders.
Add _update_suggested_precision() to sensor core; syncs entity registry
suggested_display_precision on every coordinator update.

Interval price sensors get full precision (2 or 4 dp); other MONETARY sensors
get half precision (1 or 2 dp) as sensible default.

Impact: Price sensor states and attributes now correctly use 4 decimal places
in base-currency mode (was always 2). Display precision in dashboards updates
automatically when currency mode changes.

2f704a35a3 refactor: remove dead code across integration
Remove unused functions, constants, and entity definitions that were
left over from previous refactorings. All removed code was either
superseded by better implementations or never actually called.

Removed functions:
- entity_utils/helpers.py: translate_level(), translate_rating_level()
  (HA handles ENUM translation automatically via translations/*.json)
- entity_utils/attributes.py: build_timestamp_attribute(),
  build_period_attributes() (superseded by inline implementations)
- sensor/helpers.py: get_hourly_price_value(), aggregate_window_data()
  (replaced by Calculator Pattern in sensor/calculators/)

Removed constants and definitions:
- const.py: CONF_CHART_DATA_CONFIG (DATA_CHART_CONFIG is the active one),
  PRICE_LEVEL_OPTIONS, PRICE_RATING_OPTIONS, VOLATILITY_OPTIONS,
  PRICE_TREND_OPTIONS (never imported; options defined inline in
  definitions.py due to HA import timing constraints),
  async_get_home_type_translation() (sync version used instead)
- coordinator/core.py: FRESH_TO_CACHED_SECONDS (leftover from old
  caching strategy, never referenced)
- switch/definitions.py: BEST_PRICE_SWITCH_ENTITIES (duplicate of
  BEST_PRICE_SWITCH_ENTITY_DESCRIPTIONS using base class instead of
  custom TibberPricesSwitchEntityDescription subclass)

Cleanup:
- entity_utils/__init__.py: Remove exports for deleted functions
- sensor/helpers.py: Remove now-unused imports (timedelta,
  get_intervals_for_day_offsets, get_price_value, Callable)
- entity_utils/helpers.py: Remove unused get_price_level_translation
  import after translate_level() removal
- sensor/definitions.py: Update 7x "Keep in sync with *_OPTIONS"
  comments to reference individual PRICE_LEVEL_*/PRICE_RATING_*/
  VOLATILITY_* constants instead

Impact: No user-visible changes. Reduces codebase by ~130 lines.
Improves maintainability by eliminating misleading dead code.

60e05e0815 refactor(currency)!: rename major/minor to base/subunit currency terminology
Complete terminology migration from confusing "major/minor" to clearer
"base/subunit" currency naming throughout entire codebase, translations,
documentation, tests, and services.

BREAKING CHANGES:

1. **Service API Parameters Renamed**:
   - `get_chartdata`: `minor_currency` → `subunit_currency`
   - `get_apexcharts_yaml`: Updated service_data references from
     `minor_currency: true` to `subunit_currency: true`
   - All automations/scripts using these parameters MUST be updated

2. **Configuration Option Key Changed**:
   - Config entry option: Display mode setting now uses new terminology
   - Internal key: `currency_display_mode` values remain "base"/"subunit"
   - User-facing labels updated in all 5 languages (de, en, nb, nl, sv)

3. **Sensor Entity Key Renamed**:
   - `current_interval_price_major` → `current_interval_price_base`
   - Entity ID changes: `sensor.tibber_home_current_interval_price_major`
     → `sensor.tibber_home_current_interval_price_base`
   - Energy Dashboard configurations MUST update entity references

4. **Function Signatures Changed**:
   - `format_price_unit_major()` → `format_price_unit_base()`
   - `format_price_unit_minor()` → `format_price_unit_subunit()`
   - `get_price_value()`: Parameter `in_euro` deprecated in favor of
     `config_entry` (backward compatible for now)

5. **Translation Keys Renamed**:
   - All language files: Sensor translation key
     `current_interval_price_major` → `current_interval_price_base`
   - Service parameter descriptions updated in all languages
   - Selector options updated: Display mode dropdown values

  calculate_periods_with_relaxation() calls (2 locations)

Migration Guide:

1. **Update Service Calls in Automations/Scripts**:
   \`\`\`yaml
   # Before:
   service: tibber_prices.get_chartdata
   data:
     minor_currency: true

   # After:
   service: tibber_prices.get_chartdata
   data:
     subunit_currency: true
   \`\`\`

2. **Update Energy Dashboard Configuration**:
   - Settings → Dashboards → Energy
   - Replace sensor entity:
     `sensor.tibber_home_current_interval_price_major` →
     `sensor.tibber_home_current_interval_price_base`

3. **Review Integration Configuration**:
   - Settings → Devices & Services → Tibber Prices → Configure
   - New "Currency Display Settings" step added
   - Default mode depends on currency (EUR → subunit, Scandinavian → base)

Rationale:

The "major/minor" terminology was confusing and didn't clearly communicate:
- **Major** → Unclear if this means "primary" or "large value"
- **Minor** → Easily confused with "less important" rather than "smaller unit"

New terminology is precise and self-explanatory:
- **Base currency** → Standard ISO currency (€, kr, $, £)
- **Subunit currency** → Fractional unit (ct, øre, ¢, p)

This aligns with:
- International terminology (ISO 4217 standard)
- Banking/financial industry conventions
- User expectations from payment processing systems

Impact: Aligns currency terminology with international standards. Users must
update service calls, automations, and Energy Dashboard configuration after
upgrade.

c2b9908e69 refactor(naming): complete class naming convention alignment
Renamed 25 public classes + 1 Enum to include TibberPrices prefix
following Home Assistant integration naming standards.

All classes now follow pattern: TibberPrices{SemanticPurpose}
No package hierarchy in names (import path is namespace).

Key changes:
- Coordinator module: DataFetcher, DataTransformer, ListenerManager,
  PeriodCalculator, TimeService (203 usages), CacheData
- Config flow: CannotConnectError, InvalidAuthError
- Entity utils: IconContext
- Sensor calculators: BaseCalculator + 8 subclasses
- Period handlers: 5 NamedTuples (PeriodConfig, PeriodData,
  PeriodStatistics, ThresholdConfig, IntervalCriteria)
- Period handlers: SpikeCandidateContext (dataclass → NamedTuple)
- API: QueryType Enum

Documentation updates:
- AGENTS.md: Added Pyright code generation guidelines
- planning/class-naming-refactoring-plan.md: Complete execution log

Quality metrics:
- 0 Pyright errors (strict type checking)
- 0 Ruff errors (linting + formatting)
- All hassfest checks passed
- 79 files validated

Impact: Aligns with HA Core standards (TibberDataCoordinator pattern).
No user-facing changes - internal refactor only.

625bc222ca refactor(coordinator): centralize time operations through TimeService
Introduce TimeService as single source of truth for all datetime operations,
replacing direct dt_util calls throughout the codebase. This establishes
consistent time context across update cycles and enables future time-travel
testing capability.

Core changes:
- NEW: coordinator/time_service.py with timezone-aware datetime API
- Coordinator now creates TimeService per update cycle, passes to calculators
- Timer callbacks (#2, #3) inject TimeService into entity update flow
- All sensor calculators receive TimeService via coordinator reference
- Attribute builders accept time parameter for timestamp calculations

Key patterns replaced:
- dt_util.now() → time.now() (single reference time per cycle)
- dt_util.parse_datetime() + as_local() → time.get_interval_time()
- Manual interval arithmetic → time.get_interval_offset_time()
- Manual day boundaries → time.get_day_boundaries()
- round_to_nearest_quarter_hour() → time.round_to_nearest_quarter()

Import cleanup:
- Removed dt_util imports from ~30 files (calculators, attributes, utils)
- Restricted dt_util to 3 modules: time_service.py (operations), api/client.py
  (rate limiting), entity_utils/icons.py (cosmetic updates)
- datetime/timedelta only for TYPE_CHECKING (type hints) or duration arithmetic

Interval resolution abstraction:
- Removed hardcoded MINUTES_PER_INTERVAL constant from 10+ files
- New methods: time.minutes_to_intervals(), time.get_interval_duration()
- Supports future 60-minute resolution (legacy data) via TimeService config

Timezone correctness:
- API timestamps (startsAt) already localized by data transformation
- TimeService operations preserve HA user timezone throughout
- DST transitions handled via get_expected_intervals_for_day() (future use)

Timestamp ordering preserved:
- Attribute builders generate default timestamp (rounded quarter)
- Sensors override when needed (next interval, daily midnight, etc.)
- Platform ensures timestamp stays FIRST in attribute dict

Timer integration:
- Timer #2 (quarter-hour): Creates TimeService, calls _handle_time_sensitive_update(time)
- Timer #3 (30-second): Creates TimeService, calls _handle_minute_update(time)
- Consistent time reference for all entities in same update batch

Time-travel readiness:
- TimeService.with_reference_time() enables time injection (not yet used)
- All calculations use time.now() → easy to simulate past/future states
- Foundation for debugging period calculations with historical data

Impact: Eliminates timestamp drift within update cycles (previously 60+ independent
dt_util.now() calls could differ by milliseconds). Establishes architecture for
time-based testing and debugging features.

4876a2cc29 refactor(entity_utils): extract shared helpers from sensor platform
Created entity_utils/helpers.py with platform-agnostic utility functions:
- get_price_value(): Price unit conversion (major/minor currency)
- translate_level(): Price level translation
- translate_rating_level(): Rating level translation
- find_rolling_hour_center_index(): Rolling hour window calculations

These functions moved from sensor/helpers.py as they are used by both
sensor and binary_sensor platforms. Remaining sensor/helpers.py now
contains only sensor-specific helpers (aggregate_price_data, etc.).

Updated imports:
- sensor/core.py: Import from entity_utils instead of sensor.helpers
- entity_utils/icons.py: Fixed find_rolling_hour_center_index import
- binary_sensor platforms: Can now use shared helpers

Added clear docstrings explaining:
- entity_utils/helpers.py: Platform-agnostic utilities
- sensor/helpers.py: Sensor-specific aggregation functions

Impact: Better code reuse, clearer responsibility boundaries between
platform-specific and shared utilities.
