x86-nvme-disk-health-monitor-10.ino
Python monitor for SSD NVMe M.2 health, temperature, and ID via smartctl.
This script queries the M.2 NVMe controller via smartmontools. It extracts model, serial number, and crucially, temperature to prevent overheating in a fanless chassis. Run with root privileges (sudo python3 script.py) as smartctl requires device access. Install dependencies: sudo apt install smartmontools.
