wttr.in/New+York or wttr.in/New%20Yorkwttr.in/JFK, wttr.in/SVO?m (Celsius, km/h)?u (Fahrenheit, mph)?1?0?T (better for parsing)Perfect for heartbeat or status display:
import subprocess
def get_weather(city="Moscow"):
result = subprocess.run(
f'curl -s "wttr.in/{city}?format=%c+%t"',
shell=True, capture_output=True, text=True
)
return result.stdout.strip()
# Use in heartbeat:
weather = get_weather()
show_face("happy", f"SAY:{weather}")
# Quick
curl -s "wttr.in/Moscow?format=3"
→ Moscow: ☀️ -5°C
# Detailed
curl -s "wttr.in/Moscow?format=%l:+%c+%t+(%h+humidity,+%w+wind)"
→ Moscow: ☀️ -5°C (45% humidity, ↑10km/h wind)
If wttr.in is down, use Open-Meteo (JSON, no key):
# Get coordinates first (Moscow: 55.75, 37.62)
curl -s "https://api.open-meteo.com/v1/forecast?latitude=55.75&longitude=37.62¤t_weather=true"
Returns JSON with temperature, windspeed, weathercode.
