```bash
# UFW (Ubuntu)
sudo ufw allow 22/tcp
sudo ufw allow 80/tcp
sudo ufw allow 443/tcp
sudo ufw enable
```
### 2. Environment Variables
Never commit `.env` file. Use secure methods to transfer:
```bash
# On server
touch .env
chmod 600 .env
nano .env # Add your configuration
```
### 3. Database Permissions
```bash
chmod 700 data/
chmod 600 data/meshtastic.db
```
### 4. Regular Updates
```bash
# Update system packages
sudo apt update && sudo apt upgrade -y
# Update Node.js dependencies
npm audit fix
npm update
```
### 5. Monitoring
Install monitoring tools:
```bash
# PM2 for process management
npm install -g pm2
pm2 start src/server.js --name meshtastic-dashboard
pm2 startup
pm2 save
```
## Backup Strategy
### Automated Backup Script
Create `/opt/backup-meshtastic.sh`:
```bash
#!/bin/bash
BACKUP_DIR="/opt/backups/meshtastic"
DATE=$(date +%Y%m%d_%H%M%S)
mkdir -p $BACKUP_DIR
# Backup database
cp /opt/meshtastic-dashboard/data/meshtastic.db $BACKUP_DIR/db_$DATE.db
# Backup configuration
cp /opt/meshtastic-dashboard/.env $BACKUP_DIR/env_$DATE.txt
# Keep only last 7 days
find $BACKUP_DIR -name "db_*.db" -mtime +7 -delete
find $BACKUP_DIR -name "env_*.txt" -mtime +7 -delete
echo "Backup completed: $DATE"
```
Add to crontab:
```bash
chmod +x /opt/backup-meshtastic.sh
crontab -e
# Add: 0 3 * * * /opt/backup-meshtastic.sh
```
## Monitoring and Logs
### View Logs
```bash
# Systemd logs
sudo journalctl -u meshtastic-dashboard -f
# Application logs
tail -f /opt/meshtastic-dashboard/logs/combined.log
tail -f /opt/meshtastic-dashboard/logs/error.log
```
### Log Rotation
Create `/etc/logrotate.d/meshtastic-dashboard`:
```
/opt/meshtastic-dashboard/logs/*.log {
daily
rotate 14
compress
delaycompress
notifempty
missingok
copytruncate
}
```
## Performance Optimization
### 1. Enable Node.js Clustering
For multi-core servers, modify `src/server.js` to use the cluster module.
### 2. Database Optimization
```bash
# Vacuum database periodically
sqlite3 data/meshtastic.db "VACUUM;"
```
### 3. Nginx Caching
Add to nginx configuration:
```nginx
location /css/ {
expires 1y;
add_header Cache-Control "public, immutable";
}
location /js/ {
expires 1y;
add_header Cache-Control "public, immutable";
}
```
## Troubleshooting
### Application Won't Start
1. Check logs: `sudo journalctl -u meshtastic-dashboard -n 50`
2. Verify Node.js version: `node --version`
3. Check port availability: `sudo netstat -tlnp | grep 3000`
4. Verify permissions on data directory
### MQTT Connection Issues
1. Check broker is accessible: `telnet mqtt.meshtastic.org 1883`
2. Verify credentials in `.env`
3. Check firewall rules
### Database Errors
1. Check disk space: `df -h`
2. Verify database permissions: `ls -la data/`
3. Try rebuilding: `rm data/meshtastic.db && npm start`
## Scaling Considerations
For high traffic deployments:
1. **Load Balancing**: Use multiple instances behind nginx
2. **Database**: Consider PostgreSQL for better concurrency
3. **Caching**: Add Redis for session storage
4. **CDN**: Use CloudFlare for static assets
5. **Monitoring**: Add Prometheus + Grafana
## Maintenance
### Weekly Tasks
- Review error logs
- Check disk space
- Verify backups
### Monthly Tasks
- Update dependencies
- Review security advisories
- Optimize database
- Rotate API keys if used
### Quarterly Tasks
- Review access logs
- Update SSL certificates (if not using auto-renewal)
- Performance audit
- Security audit
## Support
For deployment issues:
1. Check logs first
2. Review documentation
3. Check GitHub issues
4. Contact maintainers

- `msh/US/2/json/#` - Specific channel
### Data Retention
Configure automatic data purging:
- **DATA_RETENTION_DAYS**: Number of days to keep data (default: 30)
- **PURGE_CRON_SCHEDULE**: Cron schedule for purging (default: 0 2 * * * = daily at 2 AM)
You can also manually purge data from the Settings tab in the web interface.
### Security
**IMPORTANT**: Change the `SESSION_SECRET` in your `.env` file to a random string for production use.
## Usage
### Dashboard Overview
The dashboard provides several tabs:
1. **Overview** - Statistics and recent messages at a glance
2. **Map** - Interactive map showing GPS locations of all nodes
3. **Messages** - Send and view message history
4. **Nodes** - View all discovered nodes and their metadata
5. **Settings** - Data management and application settings
### Sending Messages
1. Navigate to the **Messages** tab
2. Type your message in the text field
3. Select the channel (0-7)
4. Click **Send**
Messages will be broadcast to the mesh network via MQTT.
### Viewing Node Details
1. Navigate to the **Nodes** tab
2. Click on any node card to view detailed information
3. Modal will display:
- Node ID and names
- Hardware model and firmware version
- Battery level and voltage
- Signal metrics
- Last heard timestamp
### Map View
The **Map** tab displays GPS locations of all nodes:
- Click on markers to see node details
- Map automatically fits to show all nodes
- Click **Refresh Map** to update positions
### Data Management
From the **Settings** tab:
1. Select retention period (7, 14, 30, 60, or 90 days)
2. Click **Purge Old Data**
3. Confirm the action
This will delete messages, positions, and telemetry older than the selected period.
## API Endpoints
The application provides a REST API for programmatic access:
### Authentication
- `POST /api/login` - Login with username/password
- `POST /api/logout` - Logout current session
- `GET /api/auth/status` - Check authentication status
### Data Access
- `GET /api/nodes` - Get all nodes
- `GET /api/nodes/:nodeId` - Get specific node details
- `GET /api/positions` - Get latest positions for all nodes
- `GET /api/positions/:nodeId` - Get position history for a node
- `GET /api/messages` - Get recent messages
- `GET /api/messages/node/:nodeId` - Get messages for a specific node
- `GET /api/telemetry/:nodeId` - Get telemetry history for a node
- `GET /api/stats` - Get dashboard statistics
### Actions
- `POST /api/messages/send` - Send a message to the mesh
- `POST /api/purge` - Purge old data
### Status
- `GET /api/mqtt/status` - Get MQTT connection status
All endpoints (except login) require authentication.
## Database Schema
The application uses SQLite with the following tables:
- **users** - User accounts for authentication
- **nodes** - Meshtastic node information
- **positions** - GPS position updates
- **messages** - Text messages
- **telemetry** - Device telemetry data
- **activity_log** - User activity logging
Database file location: `data/meshtastic.db`
## Logging
Logs are stored in the `logs/` directory:
- `combined.log` - All log messages
- `error.log` - Error messages only
Log level can be configured with `LOG_LEVEL` in `.env` (debug, info, warn, error).
## Troubleshooting
### Cannot connect to MQTT broker
1. Check your internet connection
2. Verify MQTT broker URL in `.env`
3. Check username/password if using a private broker
4. Review logs in `logs/error.log`
### No data appearing
1. Verify MQTT connection (check status indicator in header)
2. Ensure MQTT topic is correct for your region
3. Check that there is active mesh traffic on the topic
4. Review logs for any error messages
### Database errors
1. Ensure the `data/` directory is writable
2. Check disk space
3. Try deleting `data/meshtastic.db` and restarting (this will delete all data)
### Login issues
1. Verify user was created successfully with `npm run create-user`
2. Check SESSION_SECRET is set in `.env`
3. Clear browser cookies and try again
## Development
### Project Structure
- **Backend**: Express.js server with REST API
- **Frontend**: Vanilla JavaScript (no frameworks)
- **Database**: SQLite with better-sqlite3
- **MQTT**: mqtt.js client
- **Map**: Leaflet.js for interactive maps
- **Logging**: Winston for structured logging
- **Security**: bcrypt for password hashing, express-session for sessions
### Adding Features
1. **New API endpoint**: Add route to `src/routes/api.js`
2. **New database table**: Modify `src/database/db.js` and `src/database/queries.js`
3. **MQTT message handler**: Update `src/mqtt/client.js`
4. **Frontend UI**: Modify `public/index.html`, `public/css/style.css`, and `public/js/app.js`
## Contributing
Contributions are welcome! Please ensure:
1. Code follows existing style conventions
2. All features are properly documented
3. Security best practices are followed
4. No sensitive data in commits
## Security Considerations
- Change default `SESSION_SECRET` in production
- Use HTTPS in production (configure reverse proxy)
- Regularly update dependencies
- Review and limit access to MQTT credentials
- Use strong passwords for user accounts
- Enable firewall rules to restrict access
