- # Weather (Deutsch)
+ # Wetter
- Fast, key-free weather information for everyday use.
+ Schnelle, schluesselfreie Wetterauskunft fuer den Alltag.
- ## Übersicht & Zweck
+ ## Zweck
- Answers "What will the weather be like?" questions without an API key (data source: wttr.in).
- Delivers current weather (temperature, feels-like, wind, humidity, UV) plus a
- compact 3-day forecast. **User-neutral:** no fixed location in the code — the location
- comes from the request or from `assist/prefs.json` (`wetter_default_location`),
- which the LLM fills in interactively with the user.
+ Beantwortet „Wie wird das Wetter?"-Fragen ohne API-Key (Datenquelle: wttr.in).
+ Liefert aktuelles Wetter (Temperatur, gefuehlt, Wind, Luftfeuchte, UV) plus eine
+ kompakte 3-Tage-Vorschau. **Userneutral:** kein fester Standort im Code — der Ort
+ kommt aus der Anfrage oder aus `assist/prefs.json` (`wetter_default_location`),
+ die das LLM interaktiv mit dem Nutzer fuellt.
- ## Triggers
+ ## Trigger
- | User input | Action |
+ | Nutzereingabe | Aktion |
|---|---|
- | "Weather for Potsdam?" / "What will the weather be like in Hamburg?" | `wetter_core.py "<location>"` |
- | "Weather tomorrow?" (without location) | `wetter_core.py --default` (location from prefs) |
- | "My default weather location is Potsdam" | `wetter_core.py --set-default "Potsdam"` |
- | Coordinates known | `wetter_core.py <lat> <lon>` |
+ | „Wetter fuer Potsdam?" / „Wie wird das Wetter in Hamburg?" | `wetter_core.py "<Ort>"` |
+ | „Wetter morgen?" (ohne Ort) | `wetter_core.py --default` (Ort aus prefs) |
+ | „Mein Standard-Wetterort ist Potsdam" | `wetter_core.py --set-default "Potsdam"` |
+ | Koordinaten bekannt | `wetter_core.py <lat> <lon>` |
- ## Workflow & Vorgehen
+ ## Workflow
```
- 1. Determine location: from request; else prefs.json (wetter_default_location);
- else ask user interactively + optionally save as default.
- 2. Query wetter_core.py (wttr.in, 2 attempts, 30-min cache).
- 3. Present readable weather text + 3-day forecast.
+ 1. Ort bestimmen: aus Anfrage; sonst prefs.json (wetter_default_location);
+ sonst Nutzer interaktiv fragen + optional als Default speichern.
+ 2. wetter_core.py abfragen (wttr.in, 2 Versuche, 30-min-Cache).
+ 3. Lesbaren Wetter-Text + 3-Tage-Vorschau praesentieren.
```
- ## CLI Entry Point (wetter_core.py)
+ ## CLI-Einstieg (wetter_core.py)
```bash
- python wetter_core.py "Potsdam" # location
- python wetter_core.py 52.6789 13.5878 # coordinates
- python wetter_core.py --default # location from prefs.json
+ python wetter_core.py "Potsdam" # Ort
+ python wetter_core.py 52.6789 13.5878 # Koordinaten
+ python wetter_core.py --default # Ort aus prefs.json
python wetter_core.py --set-default "Potsdam"
```
## Store (optional)
- - **No mandatory store.** Optional short cache `assist/wetter/.cache.json`
- (TTL 30 min, best-effort) — avoids repeated network calls.
- - Location preference in `assist/prefs.json` (`wetter_default_location`).
+ - **Kein Pflicht-Store.** Optionaler Kurz-Cache `assist/wetter/.cache.json`
+ (TTL 30 min, best-effort) — vermeidet wiederholte Netzabrufe.
+ - Standortpraeferenz in `assist/prefs.json` (`wetter_default_location`).
- ## Attitude
+ ## Haltung
- We use wttr.in as the key-free default source, but are open to other weather
- backends (e.g. DWD/OpenWeather) if the user prefers them.
+ Wir nutzen wttr.in als schluesselfreie Default-Quelle, sind aber offen fuer
+ andere Wetter-Backends (z.B. DWD/OpenWeather), falls der Nutzer das wuenscht.
- ## Privacy
+ ## Datenschutz
- - Only the location name/coordinates go to wttr.in (required for the query).
- - No telemetry, no account. Cache + preference stay local.
+ - Nur der Ortsname/die Koordinaten gehen an wttr.in (noetig fuer die Abfrage).
+ - Keine Telemetrie, kein Konto. Cache + Praeferenz bleiben lokal.
