Julian Pawlowski 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

Changes by Category:

**Core Code (Python)**:
- const.py: Renamed all format_price_unit_*() functions, updated docstrings
- entity_utils/helpers.py: Updated get_price_value() with config-driven
  conversion and backward-compatible in_euro parameter
- sensor/__init__.py: Added display mode filtering for base currency sensor
- sensor/core.py:
  * Implemented suggested_display_precision property for dynamic decimal places
  * Updated native_unit_of_measurement to use get_display_unit_string()
  * Updated all price conversion calls to use config_entry parameter
- sensor/definitions.py: Renamed entity key and updated all
  suggested_display_precision values (2 decimals for most sensors)
- sensor/calculators/*.py: Updated all price conversion calls (8 calculators)
- sensor/helpers.py: Updated aggregate_price_data() signature with config_entry
- sensor/attributes/future.py: Updated future price attributes conversion

**Services**:
- services/chartdata.py: Renamed parameter minor_currency → subunit_currency
  throughout (53 occurrences), updated metadata calculation
- services/apexcharts.py: Updated service_data references in generated YAML
- services/formatters.py: Renamed parameter use_minor_currency →
  use_subunit_currency in aggregate_hourly_exact() and get_period_data()
- sensor/chart_metadata.py: Updated default parameter name

**Translations (5 Languages)**:
- All /translations/*.json:
  * Added new config step "display_settings" with comprehensive explanations
  * Renamed current_interval_price_major → current_interval_price_base
  * Updated service parameter descriptions (subunit_currency)
  * Added selector.currency_display_mode.options with translated labels
- All /custom_translations/*.json:
  * Renamed sensor description keys
  * Updated chart_metadata usage_tips references

**Documentation**:
- docs/user/docs/actions.md: Updated parameter table and feature list
- docs/user/versioned_docs/version-v0.21.0/actions.md: Backported changes

**Tests**:
- Updated 7 test files with renamed parameters and conversion logic:
  * test_connect_segments.py: Renamed minor/major to subunit/base
  * test_period_data_format.py: Updated period price conversion tests
  * test_avg_none_fallback.py: Fixed tuple unpacking for new return format
  * test_best_price_e2e.py: Added config_entry parameter to all calls
  * test_cache_validity.py: Fixed cache data structure (price_info key)
  * test_coordinator_shutdown.py: Added repair_manager mock
  * test_midnight_turnover.py: Added config_entry parameter
  * test_peak_price_e2e.py: Added config_entry parameter, fixed price_avg → price_mean
  * test_percentage_calculations.py: Added config_entry mock

**Coordinator/Period Calculation**:
- coordinator/periods.py: Added config_entry parameter to
  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.

## Automation Examples> **Note:** See the [full automation examples guide](https://jpawlowski.github.io/hass.tibber_prices/user/automation-examples) for more advanced recipes.
### Run Appliances During Cheap Hours
Use the `binary_sensor.tibber_best_price_period` to automatically start appliances during detected best price periods:
```yaml
automation:
- alias: "Run Dishwasher During Cheap Hours"
trigger:
- platform: state
entity_id: binary_sensor.tibber_best_price_period
to: "on"
condition:
- condition: time
after: "21:00:00"
before: "06:00:00"
action:
- service: switch.turn_on
target:
entity_id: switch.dishwasher
```
> **Learn more:** The [period calculation guide](https://jpawlowski.github.io/hass.tibber_prices/user/period-calculation) explains how Best/Peak Price periods are identified and how you can configure filters (flexibility, minimum distance from average, price level filters with gap tolerance).
### Notify on Extremely High Prices
Get notified when prices reach the VERY_EXPENSIVE level:
```yaml
automation:
- alias: "Notify on Very Expensive Electricity"
trigger:
- platform: state
entity_id: sensor.tibber_current_interval_price_level
to: "VERY_EXPENSIVE"
action:
- service: notify.mobile_app
data:
title: "⚠️ High Electricity Prices"
message: "Current electricity price is in the VERY EXPENSIVE range. Consider reducing consumption."
```
### Temperature Control Based on Price Ratings
Adjust heating/cooling when current prices are significantly above the 24h average:
```yaml
automation:
- alias: "Reduce Heating During High Price Ratings"
trigger:
- platform: numeric_state
entity_id: sensor.tibber_current_interval_price_rating
above: 20 # More than 20% above 24h average
action:
- service: climate.set_temperature
target:
entity_id: climate.living_room
data:
temperature: 19 # Lower target temperature
```
### Smart EV Charging Based on Tomorrow's Prices
Start charging when tomorrow's prices drop below today's average:
```yaml
automation:
- alias: "Smart EV Charging"
trigger:
- platform: state
entity_id: binary_sensor.tibber_best_price_interval
to: "on"
condition:
- condition: numeric_state
entity_id: sensor.tibber_current_interval_price_rating
below: -15 # At least 15% below average
- condition: numeric_state
entity_id: sensor.ev_battery_level
below: 80
action:
- service: switch.turn_on
target:
entity_id: switch.ev_charger
```
## Troubleshooting
### No data appearing
1. Check your API token is valid at [developer.tibber.com](https://developer.tibber.com/settings/access-token)
2. Verify you have an active Tibber subscription
3. Check the Home Assistant logs for detailed error messages (`Settings > System > Logs`)
4. Restart the integration: `Settings > Devices & Services > Tibber Price Information & Ratings > ⋮ > Reload`
### Missing tomorrow's price data
- Tomorrow's price data typically becomes available between **13:00 and 15:00** each day (Nordic time)
- The integration automatically checks more frequently during this window
- Check `binary_sensor.tibber_tomorrows_data_available` to see if data is available
- If data is unavailable after 15:00, verify it's available in the Tibber app first
### Prices not updating at quarter-hour boundaries
- Entities automatically refresh at 00/15/30/45-minute marks without waiting for API polls
- Check `sensor.tibber_data_expiration` to verify data freshness
- The integration caches data intelligently and survives Home Assistant restarts
### Currency or units showing incorrectly
- Currency is automatically detected from your Tibber account
- Display mode (base currency vs. subunit) can be configured in integration options: `Settings > Devices & Services > Tibber Price Information & Ratings > Configure`
- Supported currencies: EUR, NOK, SEK, DKK, USD, and GBP
- Smart defaults apply: EUR users get subunit (ct), Scandinavian users get base currency (kr)
## Advanced Features
### Sensor Attributes
Every sensor includes rich attributes beyond just the state value. These attributes provide context, timestamps, and additional data useful for automations and templates.
**Standard attributes available on most sensors:**
- `timestamp` - ISO 8601 timestamp for the data point
- `description` - Brief explanation of what the sensor represents
- `level_id` and `level_value` - For price level sensors (e.g., `VERY_CHEAP` = -2)
**Extended descriptions** (enable in integration options):
- `long_description` - Detailed explanation of the sensor's purpose
- `usage_tips` - Practical suggestions for using the sensor in automations
**Example - Current Price sensor attributes:**
```yaml
timestamp: "2025-11-03T14:15:00+01:00"
description: "The current electricity price per kWh"
long_description: "Shows the current price per kWh from your Tibber subscription"
usage_tips: "Use this to track prices or to create automations that run when electricity is cheap"
```
**Example template using attributes:**
```yaml
template:
- sensor:
- name: "Price Status"
state: >
{% set price = states('sensor.tibber_current_electricity_price') | float %}
{% set timestamp = state_attr('sensor.tibber_current_electricity_price', 'timestamp') %}
Price at {{ timestamp }}: {{ price }} ct/kWh
```

### Custom Actions
The integration provides custom actions (they still appear as services under the hood) for advanced use cases. These actions show up in Home Assistant under **Developer Tools → Actions**.
- `tibber_prices.get_chartdata` - Get price data in chart-friendly formats for any visualization card
- `tibber_prices.get_apexcharts_yaml` - Generate complete ApexCharts configurations
- `tibber_prices.refresh_user_data` - Manually refresh account information
📖 **[Action documentation and examples →](https://jpawlowski.github.io/hass.tibber_prices/user/actions)**
### Chart Visualizations (Optional)
The integration includes built-in support for creating price visualization cards with automatic Y-axis scaling and color-coded series.
<img src="docs/user/static/img/charts/rolling-window.jpg" width="600" alt="Example: Dynamic 48h rolling window chart">
_Optional: Dynamic 48h chart with automatic Y-axis scaling - generated via `get_apexcharts_yaml` action_
