Euskalmet Skill

Specialized tool for retrieving weather forecast data from the Euskalmet (Basque Meteorology Agency) API.

Usage

Execute both scripts from the skill root directory to fetch and format the weather forecast:

cd ~/.openclaw/skills/euskalmet
./venv/bin/python3 scripts/main.py && ./venv/bin/python3 scripts/format_forecast.py

Optional: Pass a username for a personalized greeting:

./venv/bin/python3 scripts/format_forecast.py --username "Urtzi"
# Output: "Egun on, Urtzi! ✨"

# Without username:
# Output: "Egun on! ✨"

You can also set EUSKALMET_GREETING_NAME in your .env file (not related to API credentials — used only for the greeting):

EUSKALMET_GREETING_NAME=Urtzi

Important: Always run both scripts in sequence. The first (main.py) downloads the raw JSON forecast data, and the second (format_forecast.py) formats it into a human-readable message in Basque.

Output

The formatted output includes:

• Current date in the header (e.g., "Gaur (2026-03-24)")
• Location name (e.g., "Laudion")
• Weather description with emoji
• Min/Max temperatures for today
• 3-day forecast with weather, emoji, and temperature ranges

Example output:

Egun on, Urtzi! ✨

Gaur (2026-03-24) Laudion **Zaparrada txikiak** 🌧️ izango dugu, 11.5 °C maximoarekin eta 5.8 °C minimoarekin.

Hona hemen datozen egunetarako joera:
📅 **Bihar:** Euri txikia 🌧️ | ⬇️ 4.4 °C  ⬆️ 9.1 °C
📅 **Etzi:** Zaparrada txikiak 🌧️ | ⬇️ 3.1 °C  ⬆️ 10.9 °C
📅 **Etzidamu:** Euri txikia 🌧️ | ⬇️ 2.2 °C  ⬆️ 11.5 °C

Egun bikaina izan! 🚀

Files

Scripts (scripts/)

• main.py — Downloads the raw JSON forecast from the Euskalmet API and saves it to forecasts/
• format_forecast.py — Reads the JSON and outputs a formatted Basque-language weather message
• test_env.py — Tests that your API credentials are valid
• download_images.py — Downloads weather icons from Euskalmet API
• test_structure.py — Verifies the skill file structure is correct

Data

• forecasts/\x3Clocation>-euskalmet.json — Raw JSON data for each location
• available-locations.json — List of available locations supported by the API

Setup

1. Virtual Environment

Create (or recreate) the virtual environment with Python 3.12:

cd ~/.openclaw/skills/euskalmet
rm -rf venv
python3.12 -m venv venv
./venv/bin/pip install -r requirements.txt

Note: The venv must use Python 3.12+ for compatibility with the latest dependencies.

2. Environment Variables

Configure your .env file with your Euskalmet API credentials:

[email protected]
EUSKALMET_API_PRIVATE_KEY=your_private_key

Optional: Add a name for a personalized greeting (not related to API credentials):

EUSKALMET_GREETING_NAME=YourName

If not set, the greeting will be "Egun on!" instead of "Egun on, YourName!"

To obtain API credentials, register at: https://www.euskalmet.euskadi.eus/

3. Test Setup

Test that your API credentials are correct:

cd ~/.openclaw/skills/euskalmet
./venv/bin/python3 scripts/test_env.py

Verify the skill file structure:

cd ~/.openclaw/skills/euskalmet
./venv/bin/python3 scripts/test_structure.py
