Changed from numeric_state with enum sensor to template using day_volatility_% attribute from binary sensor
Co-authored-by: jpawlowski <75446+jpawlowski@users.noreply.github.com>
Expanded user documentation with detailed guidance on average sensors:
1. sensors.md (+182 lines):
- New 'Average Price Sensors' section with mean vs median explanation
- 3 real-world automation examples (heat pump, dishwasher, EV charging)
- Display configuration guide with use-case recommendations
2. configuration.md (+75 lines):
- New 'Average Sensor Display Settings' section
- Comparison table of display modes (mean/median/both)
- Attribute availability details and recorder implications
3. Minor updates to installation.md and versioned docs
Impact: Users can now understand when to use mean vs median and how to
configure display format for their specific automation needs.
Add user-configurable option to choose between median and arithmetic mean
as the displayed value for all 14 average price sensors, with the alternate
value exposed as attribute.
BREAKING CHANGE: Average sensor default changed from arithmetic mean to
median. Users who rely on arithmetic mean behavior may use the price_mean attribue now, or must manually reconfigure
via Settings → Devices & Services → Tibber Prices → Configure → General
Settings → "Average Sensor Display" → Select "Arithmetic Mean" to get this as sensor state.
Affected sensors (14 total):
- Daily averages: average_price_today, average_price_tomorrow
- 24h windows: trailing_price_average, leading_price_average
- Rolling hour: current_hour_average_price, next_hour_average_price
- Future forecasts: next_avg_3h, next_avg_6h, next_avg_9h, next_avg_12h
Implementation:
- All average calculators now return (mean, median) tuples
- User preference controls which value appears in sensor state
- Alternate value automatically added to attributes
- Period statistics (best_price/peak_price) extended with both values
Technical changes:
- New config option: CONF_AVERAGE_SENSOR_DISPLAY (default: "median")
- Calculator functions return tuples: (avg, median)
- Attribute builders: add_alternate_average_attribute() helper function
- Period statistics: price_avg → price_mean + price_median
- Translations: Updated all 5 languages (de, en, nb, nl, sv)
- Documentation: AGENTS.md, period-calculation.md, recorder-optimization.md
Migration path:
Users can switch back to arithmetic mean via:
Settings → Integrations → Tibber Prices → Configure
→ General Settings → "Average Sensor Display" → "Arithmetic Mean"
Impact: Median is more resistant to price spikes, providing more stable
automation triggers. Statistical analysis from coordinator still uses
arithmetic mean (e.g., trailing_avg_24h for rating calculations).

Change relative path ../development/ to absolute path /hass.tibber_prices/developer/
since user and developer docs are now separate Docusaurus instances.
Fixes broken link warning during build.
