tfaour	644fdefa66	Add whiteboard frame mode (Nextcloud Whiteboard / Excalidraw over WebDAV) ... New third mode alongside photos/calendar: fetches a .whiteboard file over plain WebDAV (Basic auth -- generic, not Nextcloud-specific) and renders it via a small Node.js sidecar using Excalidraw's own real export code (@excalidraw/utils + @resvg/resvg-js, no headless browser), since a .whiteboard file turns out to be Excalidraw scene JSON, not an image. The sidecar runs as a second process inside this same container (Dockerfile installs Node, start.sh backgrounds it before exec'ing uvicorn) rather than a separate docker-compose service -- lightweight, stateless, reachable only at 127.0.0.1 from the Python process, nothing worth independently scaling. The rendered PNG is treated exactly like a photo from there on -- composed/quantized through the existing image_pipeline (letterboxed, never cropped) rather than a second parallel rendering pipeline. WebDAV credentials support the common "it's actually the same Nextcloud account as my CalDAV" case (an explicit opt-in checkbox, not silently inferred) while still working with any WebDAV server generically. Frame-level source (URL + owning account) follows the same owner- controls-their-own-data permission split as calendar sources and the week view's task list: only the account owner can point a frame at it, anyone linked can clear it. Honest limitation: this environment has no Node.js/npm, so render-service/ is written carefully against each library's documented API (verified via the npm registry, including transitive dependency licenses after the CalDAV/AGPL surprise earlier this session) but has never actually been executed. First real docker build is the first true test -- see render-service/README.md.	2026-07-23 17:02:08 -04:00
tfaour	fdcb444d57	Server web UI: modern themeable layout with dark mode, timezone moved into config ... Replaces the ad-hoc inline styling with a shared base template driven by CSS custom properties (light/dark palettes), a card-based two-column layout, and a persistent dark-mode toggle. Also moves quiet-hours' timezone from the container's TZ env var into a proper web UI setting (zoneinfo-backed), so it no longer needs a docker-compose.yml edit and restart to change.	2026-07-20 23:48:41 -04:00
tfaour	fd9516f5d1	Server: quiet hours (no wake overnight), zero firmware changes needed ... Purely a server-side decision: GET /frame/config hands back a longer refresh_interval_s while quiet hours are in effect (exactly the seconds until they end), and clamps the normal interval so the device's next wake lands at the boundary instead of wandering into the window, when outside it but approaching. A device already mid-sleep when quiet hours begin can still land one wake inside the window -- unavoidable without touching the firmware, since it has no wall-clock awareness -- but from that wake on it sleeps straight through to the end. Window is "HH:MM"-"HH:MM", wrap-past-midnight aware (e.g. 22:00-07:00), in the server's local timezone -- added tzdata to the Dockerfile since python:3.12-slim doesn't include it and TZ would otherwise silently resolve to nothing and fall back to UTC. Also fixed the "overdue" device-status check to account for quiet hours: without this it would falsely flag a device sleeping through a long quiet window as unreachable.	2026-07-20 23:25:43 -04:00
tfaour	5e7c47e2eb	Add FastAPI server: pulls from Immich, pre-processes for the panel ... Implements the server side of the architecture decided on: the ESP32-C6 has no PSRAM and a tight RAM budget, so all the heavy lifting (JPEG decode, resize, Floyd-Steinberg dithering, 6-color quantization, 4bpp packing) happens here instead of on-device. The frame just does a single GET and streams the response straight to SPI. - GET /frame/image: looks up the current cursor's asset in the configured Immich album, downloads its preview thumbnail, and returns it packed into the panel's exact 800x480/4bpp/2px-per-byte format (application/octet-stream, always exactly 192,000 bytes). - GET / + POST /api/config + GET /api/albums: a small web UI for entering the Immich URL/API key and picking an album, rather than cramming that into the ESP32's captive portal form. - Config (Immich creds, selected album, cursor) persists to a JSON file via a docker-compose volume mount. Verified locally with a venv (Docker isn't available in this environment): unit-tested image_pipeline against a synthetic image (exact byte count, valid panel color codes only), and ran a full end-to-end pass against a mock Immich HTTP server exercising the real /frame/image path. Pinned dependency versions in requirements.txt after hitting a real bug with unpinned floors: the latest starlette (1.3.1) resolved by `pip install fastapi` breaks Jinja2Templates outright. Not yet wired to the ESP32 side (task 6) or authenticated -- /frame/image is unauthenticated for now, fine on a trusted LAN but worth revisiting once the firmware sends a shared device token.	2026-07-18 14:35:14 -04:00
