dmi-dk

DMI (Danmarks Meteorologiske Institut) weather data and forecasts.

CLI

All interaction goes through the dmi CLI — it can be run from anywhere, with no need to point at the skill directory:

dmi <command> [options]

Prerequisites

Verify the CLI is installed:

which dmi

If missing, install it editable with pipx (from the skill directory). First make sure pipx itself is available, then install:

# Ensure pipx is installed
which pipx || python3 -m pip install --user pipx
python3 -m pipx ensurepath

# Install the dmi CLI
pipx install -e <path-to-dmi-dk-skill>

After installing, confirm dmi is on the PATH (you may need to restart the shell so pipx ensurepath takes effect):

which dmi

Pure Python standard library — no extra dependencies.

ANSWERING WEATHER QUESTIONS — READ THIS FIRST

When the user asks about the weather, always use forecast-city. This command handles everything: city lookup, forecast fetching, and pretty-printed output. Do NOT use forecast (national forecast) or city-forecast (requires a city ID) for weather questions.

The city argument is optional. If the user does not name a city, run the command with no city argument. The CLI auto-detects the user's city and country from their IP address (ipinfo.io, falling back to ipwho.is) and fetches that city's forecast — anywhere in the world, not just Denmark. If detection fails, it falls back to København.

The default command (user didn't specify a city)

# Auto-detect city from IP → daily forecast
dmi forecast-city

# This is the command you should use 90% of the time

User specified a city

# Daily forecast for the named city
dmi forecast-city Aarhus
dmi forecast-city Odense

Tomorrow or today

# Tomorrow's forecast (auto-detected city)
dmi forecast-city --tomorrow

# Today's forecast (auto-detected city)
dmi forecast-city --today

# Tomorrow for a specific city
dmi forecast-city Aarhus --tomorrow

Hourly forecast

The default output is daily aggregates. Use --hours N or --days N for hourly data:

# Next 24 hours
dmi forecast-city --hours 24

# Next 3 days (hourly)
dmi forecast-city --days 3

City name input

Accepts ASCII approximations — aa → å, oe → ø, ae → æ are normalised automatically. So kobenhavn, aarhu, aalbu all work.

NOTES

• Pure Python standard library — no extra dependencies.
• City names are normalised automatically: aa → å, oe → ø, ae → æ.
• English exonyms are translated to the Danish names DMI indexes (e.g. Copenhagen → København) for Danish locations, and IP auto-detection picks the city in the detected country so a foreign namesake (e.g. a US town called Copenhagen) is never used.
• Formatted output rounds all decimals to at most 2 places.
• --today/--tomorrow show a compact single-line format.
