dvcrn Raspberry Pi Manager
A Swiss Army knife for Raspberry Pi administration. Whether you're running a single Pi as a home server or managing a fleet of IoT nodes, this toolkit gives you instant access to system stats, GPIO pins, services, sensors, and deployment workflows.
How It Works
The script runs locally on the Pi or connects remotely via SSH. For local use, just execute the script directly. For remote management, configure SSH access.
Local Usage
bash scripts/pi-manager.sh system
bash scripts/pi-manager.sh gpio read 17
Remote Usage
export PI_HOST="pi@192.168.1.200"
export PI_SSH_KEY="~/.ssh/id_rsa"
bash scripts/pi-manager.sh --remote system
bash scripts/pi-manager.sh --remote gpio read 17
Multiple Pi support:
export PI_HOSTS="pi@node1.local,pi@node2.local,pi@node3.local"
bash scripts/pi-manager.sh --fleet system
System Monitoring
Real-time insight into your Pi's health.
