### 1. Source Code

| File | Type |
|------|------|
| `/home/byk/Code/light-match.py` | **Python source** -- Main application. A ~2600+ line daemon that matches indoor lighting to outdoor brightness using a Yoctopuce light sensor, Shelly Dimmer G3, and BLE LED strip. Includes a web UI on port 9030, solar position calculations, weather integration, BLE device control, and daemon management (start/stop/status/run). |
| `/home/byk/Code/__pycache__/light-match.cpython-312.pyc` | **Compiled bytecache** -- Python 3.12 bytecode cache of the source file above. |
