Initial project: ESP32-S3 e-ink photo frame with web UI ESP32-S3 firmware (PlatformIO) that fetches JPEGs from a photo server, decodes on-device with PSRAM, Floyd-Steinberg dithers to the Spectra 6 6-color palette, and displays on a 7.3" GDEP073E01 e-paper panel. Deep sleeps 1 hour between updates. Photo server (Python/Flask) with web UI for photo management, Traefik routing at photos.haunt.house with Google OAuth, and Home Assistant REST sensor integration.

Wire WiFi creds via .env + build-time injection, add heartbeat reporting Adopts the weather-display pattern: .env file parsed by tools/load_env.py and injected as -D compiler flags. WIFI_NETWORKS uses "SSID:password" format. ESP32 now sends a heartbeat POST after each display update so the server can track frame status for the HA integration.
