# Immich Frame
|
||
|
|
|
||
|
|
An ESP32 firmware for the [M5Stack PaperColor](https://shop.m5stack.com/products/papercolor) e-ink display that turns it into a digital photo frame powered by your [Immich](https://immich.app/) server.
|
||
|
|
|
||
|
|
## Features
|
||
|
|
|
||
|
|
- **Photo cycling modes** -- random, chronological, reverse-chronological, favorites-weighted, and recency-weighted
|
||
|
|
- **Deep sleep with batch caching** -- fetches multiple photo IDs per wake cycle to minimize network calls and extend battery life
|
||
|
|
- **6-color e-ink rendering** -- Floyd-Steinberg dithering calibrated to the Spectra 6 palette with blue noise smoothing
|
||
|
|
- **Portrait pairing** -- automatically pairs two portrait photos side-by-side
|
||
|
|
- **Metadata overlays** -- date, time, location, people, album, and camera info as caption bars or corner badges
|
||
|
|
- **Web UI** -- configure all settings, manage albums, trigger actions, and download wake logs from your browser
|
||
|
|
- **Wake logging** -- persistent CSV log of each photo cycle that survives reboots and deep sleep
|
||
|
|
|
||
|
|
## Hardware
|
||
|
|
|
||
|
|
- [M5Stack PaperColor](https://shop.m5stack.com/products/papercolor) (ESP32-S3, 600x400 Spectra 6 e-ink, 1600mAh battery)
|
||
|
|
|
||
|
|
## Requirements
|
||
|
|
|
||
|
|
- [PlatformIO](https://platformio.org/) (CLI or IDE plugin)
|
||
|
|
- An [Immich](https://immich.app/) server with an API key
|
||
|
|
|
||
|
|
## Getting Started
|
||
|
|
|
||
|
|
1. Clone the repository:
|
||
|
|
|
||
|
|
```bash
|
||
|
|
git clone https://code.cottongin.xyz/cottongin/immich-frame.git
|
||
|
|
cd immich-frame
|
||
|
|
```
|
||
|
|
|
||
|
|
2. Build and flash:
|
||
|
|
|
||
|
|
```bash
|
||
|
|
pio run -t upload
|
||
|
|
```
|
||
|
|
|
||
|
|
3. On first boot the device creates a `PaperColor-Setup` WiFi access point. Connect to it and open `192.168.4.1` in your browser.
|
||
|
|
|
||
|
|
4. Enter your WiFi credentials, Immich server URL, and API key. The device reboots and begins displaying photos.
|
||
|
|
|
||
|
|
## Configuration
|
||
|
|
|
||
|
|
Once connected to your network, access the web UI at `http://papercolor.local` to manage:
|
||
|
|
|
||
|
|
- **Slideshow** -- interval (2m to custom), cycling mode, image quality, deep sleep batch size
|
||
|
|
- **Display** -- metadata overlay content and position, translucent badge backgrounds
|
||
|
|
- **Albums** -- filter photos by specific Immich albums
|
||
|
|
- **Device** -- sync time, download/clear wake logs, deep sleep, reboot, factory reset
|
||
|
|
|
||
|
|
## Tools
|
||
|
|
|
||
|
|
The `tools/` directory contains standalone HTML utilities for analyzing wake log CSV files:
|
||
|
|
|
||
|
|
- `log-viewer.html` -- chart and table view of a single wake log
|
||
|
|
- `log-compare.html` -- side-by-side comparison of multiple wake logs
|
||
|
|
|
||
|
|
Open them directly in your browser; no server required.
