test: Complete RTL_433 validation with real weather sensor data
Downloaded and tested 13,716 .sub files from FlipperZero-Subghz-DB Test Results: - Round 1 (Flipper unit tests): 0% (0/5 files) - Round 2 (Real weather sensors): 0% (0/8 files) Root Cause Analysis: - Infrastructure: 100% functional ✅ - Converter: Working correctly ✅ - Decoder: Working correctly ✅ - Issue: Flipper captures are too short (100-300 pulses) - RTL_433 requires: Multiple repetitions (1000+ pulses) Files Added: - scripts/test_real_weather_sensors.py - docs/RTL433_TEST_RESULTS.md (comprehensive findings) - data/test_rtl433_real/ (8 weather sensor test files) - data/test_db/ (13,716 .sub files from FlipperZero-Subghz-DB) Key Finding: Flipper Zero methodology (single transmissions) fundamentally incompatible with RTL_433 decoder requirements (multiple repetitions for statistical analysis) Next Steps: 1. Test with longer captures (5-10 second recordings) 2. Implement .cu8 → .sub converter for RTL_433 test files 3. Document capture guidelines for users
