🆕 Release Notes – Version 1.0.0

Iam excited to announce the latest version of the Price Timeline Card! This release brings hopefully several improvements, new features, and quality enhancements.

✨ New Features

• ⏱️ 15-minute interval support
  The card now supports displaying energy prices in 15-minute intervals, in addition to hourly prices.

• 🔄 Double-click toggle
  Users can now switch between today and tomorrow by double-clicking the card.

• ⚡ Flexible average price

  • The average sensor is now optional. If omitted, the card automatically calculates the average.
  • The average can be provided either as a number or as an entity ID.

• 🌍 Tibber
  Integration with the Tibber ecosystem is now easier: see the README for scripts and Python helpers to provide the correct sensor format.

• ✨ Empty data feedback
  The card now shows a message and simple animation when data (e.g., for tomorrow) is not yet available.

💡 Best Practices

• Use 15-minute data where available for higher granularity.
• Provide average only if you want to override the automatic calculation.
• Make sure attributes.data of the price sensor contains start_time and price_per_kwh entries (see README ).
