FieldClimate ET0 + Precipitation Export

Fetches the last 7 days of daily data from the FieldClimate API for a single device, then writes a CSV containing ET0 and precipitation totals. Designed for quick weekly reporting.

What it does

• Authenticates against the FieldClimate OAuth endpoint
• Requests daily data for the last 7 days for a single device
• Extracts ET0 (disease_evapotranspiration_ETo) and precipitation (Yağış [mm])
• Writes a CSV with daily values and weekly totals
• Downloads the CSV automatically when run inside Google Colab

Requirements

• Python 3.9+
• A FieldClimate account and API credentials
• A device ID for the station you want to query

Setup

1. Create a virtual environment (optional but recommended)
2. Install dependencies
3. Configure environment variables

python -m venv .venv
source .venv/bin/activate
pip install -r requirements.txt

Create a .env file in the project root:

FIELDCLIMATE_CLIENT_ID=your_client_id
FIELDCLIMATE_CLIENT_SECRET=your_client_secret
FIELDCLIMATE_USERNAME=your_username
FIELDCLIMATE_PASSWORD=your_password
FIELDCLIMATE_DEVICE_ID=your_device_id

Run

python main.py

Output

A CSV file named like fieldclimate_et0_yagis_YYYY-MM-DD.csv containing:

• Date
• ET0 (mm)
• Yağış (mm)
• Weekly totals row at the bottom

Notes

• If you run this outside Google Colab, the CSV will be saved locally and a message will be printed instead of auto-download.
• The script expects the API response to contain grid.data with the keys listed above.

Troubleshooting

• Missing credentials: ensure all FIELDCLIMATE_* variables are set in .env.
• 401/403: verify API credentials and device permissions.
