### Persistent Caching Setup
The LEDMatrix system uses persistent caching to improve performance and reduce API calls. When running with `sudo`, the system needs a persistent cache directory that survives restarts.
**Automatic Setup:**
Run the setup script to create a persistent cache directory:
```bash
chmod +x setup_cache.sh
./setup_cache.sh
```
This will:
- Create `/var/cache/ledmatrix/` directory
- Set proper ownership to your user account
- Set appropriate permissions (755)
**Manual Setup:**
If you prefer to set up manually:
```bash
sudo mkdir -p /var/cache/ledmatrix
sudo chown $USER:$USER /var/cache/ledmatrix
sudo chmod 755 /var/cache/ledmatrix
```
**Cache Locations (in order of preference):**
1. `~/.ledmatrix_cache/` (user's home directory) - **Most persistent**
2. `/var/cache/ledmatrix/` (system cache directory) - **Persistent across restarts**
3. `/opt/ledmatrix/cache/` (alternative persistent location)
4. `/tmp/ledmatrix_cache/` (temporary directory) - **NOT persistent**
**Note:** If the system falls back to `/tmp/ledmatrix_cache/`, you'll see a warning message and the cache will not persist across restarts.
