Open-Meteo Omi App

Check current weather, short forecasts, and basic air-quality readings from Omi conversations.

This is a standalone no-auth Omi app backed by the public Open-Meteo APIs. It does not require environment variables, OAuth, or API keys.

Tools

• get_current_weather: current temperature, wind, humidity, precipitation, and weather condition for a place.
• get_weather_forecast: daily forecast for the next 1-7 days.
• get_air_quality: current PM2.5, PM10, ozone, nitrogen dioxide, and US AQI where Open-Meteo has data.

Local Development

python -m venv .venv
source .venv/bin/activate
pip install -r requirements.txt
uvicorn main:app --reload --port 8080

Health check:

curl http://localhost:8080/health

Tool manifest:

curl http://localhost:8080/.well-known/omi-tools.json

Example current weather request:

curl -X POST http://localhost:8080/tools/get_current_weather \
  -H "Content-Type: application/json" \
  -d '{"location":"San Francisco","temperature_unit":"fahrenheit"}'

Example forecast request:

curl -X POST http://localhost:8080/tools/get_weather_forecast \
  -H "Content-Type: application/json" \
  -d '{"location":"London","days":3}'

Example air-quality request:

curl -X POST http://localhost:8080/tools/get_air_quality \
  -H "Content-Type: application/json" \
  -d '{"location":"Berlin"}'

Deployment

Deploy this folder as a standalone FastAPI service. Railway can use railway.toml; Heroku-style platforms can use the Procfile.

Notes

• Location lookup uses the Open-Meteo geocoding API and takes the best result.
• Forecast output is capped at 7 days so chat responses stay readable.
• Air-quality values depend on Open-Meteo coverage for the resolved coordinates.
