## Automated Gadgetbridge DB Shrink & Sync

### 1. Install Apps (F-Droid)
*   **Termux** (Terminal)
*   **Termux:Boot** (Auto-start scripts)

### 2. Configure Apps
*   **Gadgetbridge:** Settings → Auto Export → Location: `/sdcard/Documents/GB_Raw`
*   **Nextcloud:** Auto Upload → Custom Folder → Local: `/sdcard/Documents/GB_Sync` → Remote: `/Backup/Gadgetbridge`
*   **Termux:Boot:** Open app once to initialize.

### 3. Termux Setup (Run these commands)
```bash
# 1. Setup storage & install python
termux-setup-storage
pkg update -y && pkg install -y python wget

# 2. Create script directories
mkdir -p ~/scripts ~/.termux/boot

# 3. Download python script
wget -O ~/scripts/shrinkdb.py https://git.olli.info/Oliver/GadgetbridgeMqtt/raw/branch/main/termux_setup/shrinkdb.py

# 4. Create autostart launcher
printf '#!/data/data/com.termux/files/usr/bin/sh\ntermux-wake-lock\npython ~/scripts/shrinkdb.py &\n' > ~/.termux/boot/start_gb
```

### 4. Finish
**Reboot your phone.**
The script will now run automatically, shrinking DBs from `GB_Raw` and placing clean versions in `GB_Sync` for Nextcloud.
