Restorable Scenes for Home Assistant

This custom integration lets you create persistent scenes that survive Home Assistant restarts.
By contrast, Home Assistant's built-in scene.create only generates temporary scenes that disappear after a restart.

⚙️ What it does

• Capture the current state of selected entities and save them as a persistent scene.
• Persist the saved scene so it remains available after a reboot.
• Activate any created persistent scene using the standard scene.turn_on service.
• Delete persistent scenes using the provided delete service.
• Supports many common domains (light, switch, climate, media_player, etc.).
• However, full restoration is not guaranteed for all devices or attributes.
  If you need additional support, please file an Issue.

🚨 Limitations

• Some entities or attributes may not restore perfectly.
• Behavior varies depending on the device/integration.
• For support of new device types, please open an Issue.
