Code	Meaning
%c	Weather condition (emoji)
%t	Temperature
%h	Humidity
%w	Wind
%l	Location

%p	Precipitation

Tips

• URL-encode spaces: wttr.in/New+York or wttr.in/New%20York
• Airport codes work: wttr.in/JFK, wttr.in/SVO
• Force metric: ?m (Celsius, km/h)
• Force imperial: ?u (Fahrenheit, mph)
• Today only: ?1
• Current only: ?0
• No colors: ?T (better for parsing)

Integration with E-Ink

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}")

Example Responses

# 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)

Fallback: Open-Meteo API

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&current_weather=true"

Returns JSON with temperature, windspeed, weathercode.
