🌤️ Weather Notifier

A Python app that checks the weather daily, sends a push notification with the summary, and updates a Govee smart light to visually reflect current conditions. Runs unattended on a Raspberry Pi via cron.

Features

• Fetches live weather data from the OpenWeatherMap API
• Sends a daily summary via push notification (ntfy.sh)
• Sends a failure alert if the check fails — no silent failures
• Changes a Govee smart light's color based on current weather condition (clear, cloudy, rain, snow, thunderstorm, fog)
• Scales the light's brightness based on temperature
• Weekly log rotation
• Fully portable via environment-based config (tested on x86 and ARM/Raspberry Pi)

Setup

git clone https://github.com/your-username/weather-py.git
cd weather-py
python3 -m venv .venv
source .venv/bin/activate
pip install -r requirements.txt

Create a .env file:

API_KEY=your_openweathermap_api_key
LAT=your_latitude
LON=your_longitude
NTFY_TOPIC=your_unique_ntfy_topic
GOVEE_API_KEY=your_govee_api_key
GOVEE_DEVICE=your_govee_device_mac_id
GOVEE_SKU=your_govee_device_model

• Get an API key from OpenWeatherMap
• Install the ntfy app and subscribe to your chosen topic
• Get a Govee API key via the Govee Home app (Settings → Apply for API Key), then find your device's device (MAC ID) and sku (model) by calling the Govee device list endpoint

Run it:

python weather.py

Scheduling

crontab -e

0 7 * * * /path/to/weather-py/.venv/bin/python /path/to/weather-py/weather.py

Runs daily at 7:00 AM. File paths in the script are resolved relative to the script's location, so it works correctly regardless of cron's working directory.

Future Improvements

• Multi-day forecast
• Severe weather alerts
• Configurable notification schedule
• Support for multiple Govee lights simultaneously
