## Installation
```bash
opkg update
opkg install luci-app-system-hub
/etc/init.d/rpcd restart
/etc/init.d/uhttpd restart
```
## Dependencies
- **luci-base**: LuCI framework

## Usage
### Web Interface
Navigate to **System → System Hub** in LuCI.
#### Overview Tab
- System information cards
- Health metrics with visual gauges:
- CPU Load (percentage based on cores)
- Memory Usage (percentage with MB breakdown)
- Disk Usage (percentage with size info)
- CPU details (model, cores, load average)
- Temperature monitoring (color-coded: green < 60°C, orange < 80°C, red 80°C)
- Storage details for all mount points
#### Services Tab
- List of all system services
- Status indicators (running/stopped)
- Autostart status (enabled/disabled)
- Action buttons:
- Start (for stopped services)
- Stop (for running services)
- Restart (for all services)
- Enable/Disable autostart
#### System Logs Tab
- Log viewer with filter controls
- Configurable line count (50, 100, 200, 500, 1000)
- Keyword filtering
- Refresh logs on demand
- Terminal-style display (black background, green text)
#### Backup & Restore Tab
- Create and download configuration backup
- Upload and restore backup file
- System reboot with confirmation
#### Development Status Tab (Bonus)
- Mirrors the public `demo-dev-status` widget from secubox-website
- Displays overall progress, milestone groups, detailed roadmap, and project stats
- Useful to showcase transparency directly from the LuCI interface

## System Information Sources
- Hostname: `/proc/sys/kernel/hostname`
- Model: `/tmp/sysinfo/model`, `/proc/device-tree/model`
- Uptime: `/proc/uptime`
- OpenWrt version: `/etc/openwrt_release`
- Kernel: `uname -r`
- CPU info: `/proc/cpuinfo`
- Load average: `/proc/loadavg`
- Memory: `/proc/meminfo`
- Storage: `df -h`
- Temperature: `/sys/class/thermal/thermal_zone*/temp`
- Services: `/etc/init.d/*`
## Gauge Visualization
The overview page displays three circular gauges:
### CPU Load Gauge
- Percentage calculated from 1-minute load average divided by core count
- Green: < 75%
- Orange: 75-90%
- Red: > 90%
### Memory Gauge
- Percentage of memory used
- Shows "Used MB / Total MB"
- Color-coded like CPU
### Disk Gauge
- Percentage of root filesystem used
- Shows "Used / Total Size"
- Color-coded like CPU
## Security Considerations
- Service actions require write permissions in ACL
- Backup data contains sensitive configuration
- Reboot action is irreversible
- Log filtering does not sanitize sensitive data in logs
## Troubleshooting
### Services Not Showing
Check if services exist:
```bash
ls /etc/init.d/
```
### Health Metrics Not Accurate
Verify system files are accessible:
```bash
cat /proc/meminfo
cat /proc/loadavg
df -h
```
### Backup Creation Fails
Ensure sysupgrade is available:
```bash
which sysupgrade
```
### Temperature Not Displayed
Check thermal zones:
```bash
ls /sys/class/thermal/thermal_zone*/temp
```
