The record

Purpose: SMART Sniffer monitors disk health and reports early warning signs to Home Assistant.
Drive coverage: Its Attention Needed sensor monitors ATA, SATA, NVMe, and SAS drives and reports NO, MAYBE, YES, or UNSUPPORTED.
Notifications: Persistent Home Assistant notifications fire automatically when drive health changes and can escalate, de-escalate, and auto-dismiss.
Multiple machines: A lightweight Go agent runs on each monitored machine, with each drive appearing as its own Home Assistant device.
Discovery: Agents advertise over local-network mDNS/Zeroconf so Home Assistant can discover them without manual IP entry.
Disk usage: Opt-in filesystem monitoring reports total, used, and available bytes and usage percentage for configured mountpoints.
Integrations: The integration provides a service call with SMART data and assessments that can be passed to Google AI, ChatGPT, Claude, or Ollama.
API: The agent exposes HTTP endpoints for health, drive summaries, individual drive SMART data, and configured filesystem usage.
Security: Bearer-token authentication between the agent and integration is optional, and binary downloads are checked with SHA256 checksums.
Requirements: The agent requires smartmontools 7.0 or newer for JSON output support.
USB limitation: USB enclosures that block SMART passthrough are marked UNSUPPORTED with Health: Unknown.
Installation: The Home Assistant integration can be installed through HACS or manually, and the agent has Linux, macOS, and Windows installation instructions.
Security reporting: The security policy requests vulnerability reports by email and says the maintainer aims to acknowledge them within 48 hours and provide a fix or mitigation plan within 7 days for confirmed vulnerabilities.
License and maker: The repository identifies the project as MIT-licensed and built by DAB-LABS.
