Add Window Truth — weather verification using IP camera

[citriac]

Window Truth

A self-hosted weather app conflict detection tool using a cheap IP camera.

What it does

Detects when weather app predictions conflict with local observations:

• RAIN_GONE: App says rain, but window shows bright/quiet
• HIDDEN_RAIN: App says no rain, but audio RMS detects rain
• THIN_CLOUD: App says overcast, but brightness is high

Why it fits awesome-iot

• Uses IP camera (RTSP) as IoT sensor for brightness and audio
• Processes sensor data locally (Python, no cloud dependencies)
• Cross-verifies with Open-Meteo API (free, no key needed)
• Runs on any old laptop or Raspberry Pi
• MIT licensed

Results

19-day validation in Shenzhen: 75% win rate over weather apps when they disagree.
