device.py's mode-keyed dispatch is replaced by a real compositor: load a frame's widgets, compute pixel rects via app/grid.py, render each through its widget module, and composite with render_panel. Physical NEXT/BACK buttons now execute each frame's assigned FrameButtonAction rows instead of one hardcoded per-mode action. api_frames.py, manage.py, and common.py's build_manage_content are repointed to read/write the frame's widget config rows instead of the old Frame columns, and every settings page (Photos/Calendar/ Whiteboard tabs) now pre-fills its form from the same widget config the write endpoints actually save to -- previously the read and write sides would have silently diverged. The old mode selector and photo-inlay checkbox are removed along with their now-inert wiring; arbitrary widget placement subsumes what the fixed inlay split did. Ships together with Phase 1 (per-type render/action modules) since splitting the read/write cutover across deploys would have left settings changes with no visible effect.
ESPresso Frame
A DIY e-ink photo frame: an ESP32-C6 pulls photos from your Immich library and displays them on a 7.3" full-color e-paper panel, waking on a timer to refresh and spending the rest of its time in deep sleep.
- No cables to a computer, no SD card shuffling. Provisioning is a captive portal with a QR code drawn on the panel itself -- scan, join, fill in your WiFi and server address, done.
- The frame never decodes an image. A small self-hosted server does all the work (pulling from Immich, cropping, dithering, packing into the panel's exact pixel format) and hands the device a stream it can write straight to SPI. The ESP32-C6 has no PSRAM and not much SRAM to spare -- keeping it a dumb display client is what makes that workable.
- Crops toward faces, not just the center, using face bounding boxes Immich already computed for its own People feature -- no bundled face detector.
- Refresh interval and album are configurable from a web UI, no reflashing needed to change them.
Hardware
- ESP32-C6 dev board (8MB flash)
- Waveshare 7.3" E Ink Spectra 6 (E6) panel -- 800x480, 6-color, SPI
See docs/hardware.md for wiring and
docs/architecture.md for how the two halves talk
to each other.
Getting started
server/-- run the FastAPI server first (Docker Compose, points at your Immich instance). Seeserver/README.md.firmware/-- build and flash the ESP32-C6, then scan the QR codes it draws on first boot to provision it. Seefirmware/README.md.
Repo layout
firmware/ ESP-IDF project for the ESP32-C6
