Weather (Deutsch)
Fast, key-free weather information for everyday use.
Übersicht & 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.
Triggers
| User input | Action |
|---|
| "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> |
Workflow & Vorgehen
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.
CLI Entry Point (wetter_core.py)
python wetter_core.py "Potsdam"
python wetter_core.py 52.6789 13.5878
python wetter_core.py --default
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).
Attitude
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.
Privacy
- Only the location name/coordinates go to wttr.in (required for the query).
- No telemetry, no account. Cache + preference stay local.
