# NVMe SMART health — notify when any monitored field changes.
# Needs smartmontools (in preinstall PACKAGES) + passwordless sudo for
# smartctl. Set it up once:
#   echo '%sudo ALL=(ALL) NOPASSWD: /usr/sbin/smartctl' | sudo tee /etc/sudoers.d/smartctl
# Adjust /dev/nvme0n1 if your disk has a different device name.
# Note: 'temperature' drifts, so onchange will fire most hours — drop the
# temperature alternative from the grep if you only want fault-field alerts.
