🔮 SmartDisplay ESP32-S3 v1.0.0

Initial production release of SmartDisplay, an open-source, modular firmware based on ESPHome and LVGL 8 designed for the SP-ESP32-S3-1.28-BOX circular desktop display.

This firmware repurposes the commercial AliExpress AI desktop bot (originally running cloud-locked firmware from 78/xiaozhi-esp32) into a 100% local, private, full-featured Home Assistant notification display, standby clock, weather widget, and TTS voice announcement speaker.

✨ What's New & Key Highlights

🎨 Display & UI (LVGL 8)

  • Tailored Circular Geometry: Designed specifically for the 240x240 GC9A01A round IPS display.
  • 80MHz SPI Bus: Fast framebuffer transfer eliminating LVGL render delays ([W][component:419]).
  • Centered Circular Diagnostics: Redesigned system info screen with symmetric metrics and cyan header.
  • Auto-Home on Sleep: Automatically navigates back to the Standby Clock (home_page) whenever the display turns off or sleeps.

📬 Smart Notification System

  • LIFO Notification Queue: Stores up to 10 notifications in memory with interactive card carousel.
  • Material Symbols Outlined: Integrated vector glyphs (home, warning, info, thermometer, window, lightbulb, lock, notifications, etc.).
  • Dynamic Color Engine: Supports color names (white, cyan, green, orange, red, etc.) and hex codes.
  • Visual Confirmation Dialog: Dedicated modal to dismiss all cards (Green NO to keep, Red SI to clear).
  • Unread Notification Badge: Subtle amber bell above the standby clock when notifications are pending.

🔊 Audio & Voice Announcements

  • Everest ES8311 DAC & I2S: Seamless streaming via Home Assistant's announcement_pipeline.
  • Dynamic Power Gating (GPIO46): Automatically cuts amplifier power in standby, saving ~20mA and eliminating background hiss.

⛅ Standby Clock & Live Weather

  • Event-Driven SNTP Clock: Synchronized over Wi-Fi, updates strictly on minute rollover.
  • Live Weather Widget: Subscribes to Home Assistant weather.* entity with automatic condition-to-icon mapping and thematic accent colors.

📡 Passive Bluetooth Proxy

  • Long-Range BLE Extension: Forwards nearby Bluetooth sensors (e.g. Xiaomi Mi Flora plant care sensors, BTHome thermometers, BLE beacons) directly to Home Assistant.
  • Passive Mode (active: false): Captures 100% of sensor telemetry with zero connection overhead and no audio stuttering.

🔋 Power & Battery Management

  • Battery ADC Filter: Median window filtering on GPIO1 for stable voltage reporting.
  • USB-C Charging Detection: GPIO41 sensing; stays permanently awake on desk when plugged in, enters auto-sleep when on battery.
  • 1kHz Flicker-Free PWM Backlight: Dimmable via Home Assistant light.smartdisplay_backlight.
