Aus dem Backup und Live-Pull vom Pi (10.11.3.144): - dashboard.py: Grid-Linien nur im freien Hintergrund (nicht durch Widgets) - templates/index.html: komplett redesigned mit Sidebar + Topbar + Toast + Modal - plugins/clock.py: responsive Layout (1x1 bis 4x4) - plugins/system.py, weather.py, minimax.py: mit Threshold-Bars und Color-Variants - plugins/base.py: NEU — fetch_with_retry Helper (3x retry mit backoff) + render_error_banner für fehlgeschlagene API-Plugins (grosses rotes "!" Icon mit Plugin-Name und Fehler statt Crash) Cleanup: Helfer-Chaos (renderer.py/2/3, design_a/b/c.html, clock_classic.py, 23x clock_*.png, alte test_*.py) wurde bereits im vorherigen Commit entfernt.

|
||
## Quick Start
|
||
|
||
### Pi vorbereiten
|
||
|
||
```bash
|
||
sudo apt update && sudo apt install -y python3-pil python3-numpy python3-flask git
|
||
sudo raspi-config # → Interface Options → SPI → Enable
|
||
sudo reboot
|
||
```
|
||
|
||
### Setup
|
||
|
||
```bash
|
||
# Repository klonen
|
||
git clone https://git.pkop.de/Vibecode/epaper-dashboard.git
|
||
cd epaper-dashboard
|
||
|
||
# Config erstellen
|
||
cp config.example.json config.json
|
||
# → config.json editieren (Plugins + Layout)
|
||
|
||
#waveshare_epd Treiber
|
||
git clone https://github.com/waveshareteam/Waveshare_GPIO.git waveshare_epd_lib
|
||
# oder: den waveshare_epd Ordner vom vorherigen Setup übernehmen
|
||
|
||
# Services installieren
|
||
chmod +x install_services.sh
|
||
./install_services.sh
|
||
```
|
||
|
||
### Config
|
||
|
||
`config.json` — Version 2 Format (empfohlen):
|
||
|
||
```json
|
||
{
|
||
"version": 2,
|
||
"refresh_interval_s": 180,
|
||
"layout": {
|
||
"grid": { "cols": 4, "rows": 4 },
|
||
"items": [
|
||
{ "id": "c1", "plugin": "clock", "x": 0, "y": 0, "w": 2, "h": 2 },
|
||
{ "id": "w1", "plugin": "weather", "x": 2, "y": 0, "w": 2, "h": 2 },
|
||
{ "id": "st1", "plugin": "system", "x": 0, "y": 2, "w": 2, "h": 2 },
|
||
{ "id": "h1", "plugin": "hello", "x": 2, "y": 2, "w": 2, "h": 2 }
|
||
]
|
||
},
|
||
"plugin_configs": {
|
||
"hello": { "text": "Edit me!", "size": 40 }
|
||
}
|
||
}
|
||
```
|
||
|
||
**Grid:** 4 Spalten × 4 Zeilen = 16 Zellen à 200×120px. `x,y` = Spalte/Zeile oben-links, `w,h` = Breite/Höhe in Zellen.
|
||
|
||
### Web Admin
|
||
|
||
```
|
||
http://pi:8080/
|
||
```
|
||
|
||
- **Layout-Editor** — Items per Klick hinzufügen, verschieben, Größe ändern, Auto-Pack
|
||
- **Plugin-Config** — API-Keys, Locations, etc. pro Widget
|
||
- **Refresh Now** — sofortiger Display-Refresh
|
||
- **Netzwerk** — WLAN wechseln ohne SSH
|
||
|
||
Default Login: `admin` / `admin` — in `.env` mit `EPAPER_ADMIN_PASSWORD` setzen.
|
||
|
||
## Plugins
|
||
|
||

|
||

|
||
| `weather` | Open-Meteo (kein API-Key) | `location` (lat,lon), `show_uv`, `show_forecast_hours` |

|
||
|
||
## Eigenes Plugin schreiben
|
||
|
||
```python
|
||
# plugins/my_widget.py
|
||
from plugins.base import Widget
|
||
from palette import FG, BG
|
||
|
||
class Widget(Widget):
|
||
name = "my_widget"
|
||
label = "Mein Widget"
|
||
description = "Zeigt etwas"
|
||
category = "info"
|
||
|
||
config_schema = [
|
||
{"key": "api_key", "label": "API Key", "type": "secret"},
|
||
{"key": "interval", "label": "Intervall (s)", "type": "int", "default": 60},
|
||
]
|
||
default_config = {"api_key": "", "interval": 60}
|
||
|
||
def fetch(self):
|
||
return {"value": 42}
|
||
|
||
def render(self, draw, fonts, x, y, w, h):
|
||
d = self.fetch()
|
||
# w, h sind Pixel (nicht Zellen!)
|
||
draw.text((x + 10, y + 10), f"Value: {d['value']}",
|
||
font=fonts["28"], fill=FG)
|
||
```
|
||
|
||
**Palette:** `BLACK, WHITE, RED, GREEN, BLUE, YELLOW, ORANGE` + semantisch `FG, BG, OK, WARN, ALERT, INFO, ACCENT`
|
||
|
||
## Services
|
||
|
||
```bash
|
||
systemctl --user enable --now epaper-dashboard
|
||
systemctl --user enable --now epaper-admin
|
||
journalctl --user -u epaper-dashboard -f # Logs
|
||
```
|
||
|
||
**Wichtig:** `PrivateTmp=no` in den Service-Files — sonst sieht der Admin-Socket `/tmp/epaper-dashboard.sock` nicht.
|
||
|
||
## Display-Einschränkungen
|
||
|
||
- **Nur Full-Refresh:** ACeP-Displays vertragen keine schnellen Partial-Refreshes. Minimum 180s.
|
||
- **Refresh-Dauer:** Ein Full-Refresh dauert ~35-65s. Währenddessen ist das Display leer/flackernd.
|
||
- **Ghosting:** Leichtes Ghosting bei manchen Farben normal. Display nicht bei direktem Sonnenlicht ablesen.
|
||
|
||
## Recovery
|
||
|
||
Falls das konfigurierte WLAN nicht erreichbar ist: der Pi startet automatisch einen **Recovery AP**.
|
||
|
||
- **SSID:** `epaper-recovery`
|
||
- **Passwort:** `recovery1234`
|
||
- **URL:** http://10.42.0.1:8080/
|
||
|
||
Dort kannst du ein neues WLAN konfigurieren. Details in `RECOVERY.md`.
