Moved Chart Data Export sensor configuration from config flow textarea
to configuration.yaml for better maintainability and consistency with
Home Assistant standards.
Changes:
- __init__.py: Added async_setup() with CONFIG_SCHEMA for tibber_prices.chart_export
- const.py: Added DATA_CHART_CONFIG constant for hass.data storage
- options_flow.py: Simplified chart_data_export step to info-only page
- schemas.py: get_chart_data_export_schema() returns empty schema (no input fields)
- sensor/chart_data.py: Reads config from hass.data instead of config_entry.options
- All 5 translation files: Updated chart_data_export description with:
- Clear heading: "📊 Chart Data Export Sensor"
- Intro line explaining sensor purpose
- Legacy warning (⚠️) recommending service use
- Two valid use cases (✅): attribute-only tools, auto-updating data
- One discouraged use case (❌): automations should use service directly
- 3-step activation instructions
- YAML configuration example with all parameters
- Correct default behavior: today+tomorrow, 15-minute intervals, prices only
Impact: Users configure chart export in configuration.yaml instead of UI.
Sensor remains disabled by default (diagnostic sensor). Config flow shows
prominent info page guiding users toward service usage while keeping
sensor available for legacy dashboard tools that only read attributes.
When adding a new integration (no existing cache), metadata sensors
(grid_company, estimated_annual_consumption, etc.) were marked as
unavailable because coordinator._cached_user_data remained None even
after successful API call.
Root cause: update_user_data_if_needed() stored user data in
_data_fetcher.cached_user_data, but the sync back to coordinator
only happened during _load_cache() (before the API call).
Solution: Added explicit sync of cached_user_data after
handle_main_entry_update() completes, ensuring metadata is available
when sensors first access get_user_homes().
Changes:
- coordinator/core.py: Sync _cached_user_data after main entry update
- __init__.py: Kept preload cache call (helps with HA restarts)
Impact: Metadata sensors now show values immediately on fresh integration
setup, without requiring a second update cycle or manual sensor activation.
- Added new configuration options for minimum distance from average price for best and peak prices.
- Updated default values for best and peak price flexibility.
- Improved coordinator to handle midnight turnover and data rotation more effectively.
- Refactored entity initialization to streamline device information retrieval.
- Updated sensor attributes to use more descriptive names for price values.
- Enhanced translations for new configuration options in English and German.
- Improved unit tests for coordinator functionality, ensuring proper cleanup and async handling.
