What SMART Sniffer is

SMART Sniffer monitors disk health and reports warning signs to Home Assistant. Its Attention Needed sensor covers ATA, SATA, NVMe and SAS drives, assigning a status of NO, MAYBE, YES or UNSUPPORTED. When drive health changes, persistent Home Assistant notifications can appear automatically, with options to escalate, de-escalate or dismiss them automatically. A lightweight Go agent runs on each monitored machine, and each drive is represented as its own Home Assistant device. The agents use local-network mDNS/Zeroconf discovery, so Home Assistant can find them without manually entering IP addresses. Optional filesystem monitoring reports total, used and available bytes and the usage percentage for selected mountpoints. The integration can pass SMART data and assessments to Google AI, ChatGPT, Claude or Ollama. Its HTTP endpoints cover health, drive summaries, individual SMART data and configured filesystem usage. The free, MIT-licensed project supports Linux, macOS and Windows, but the agent requires smartmontools 7.0 or newer for JSON output. USB enclosures that block SMART passthrough receive an unsupported status and unknown health.

Good

  • Monitors ATA, SATA, NVMe and SAS drives.
  • Health changes can trigger persistent Home Assistant notifications.
  • Agents are discoverable without manual IP entry.
  • Free and MIT-licensed.

Watch out

  • Requires smartmontools 7.0 or newer.
  • Some USB enclosures cannot pass through SMART data.
  • Filesystem monitoring is opt-in.

Who it suits

SMART Sniffer suits Home Assistant users who want disk-health warnings across Linux, macOS or Windows machines. It may also suit users who want optional filesystem-usage reporting alongside drive monitoring.

Verdict

SMART Sniffer brings disk-health statuses and alerts into Home Assistant, with multi-machine discovery and optional filesystem reporting. Check smartmontools compatibility and USB enclosure passthrough before relying on its drive assessments.

The facts

Each one read from SMART Sniffer's own pages, with the date it was checked.

What it does

AI integration
The smart_sniffer.get_drive_data service returns cached SMART data, health assessments, filesystem usage and agent metadata for use with Google AI, ChatGPT, Claude or Ollama.checked 14 Oct 2026
API
The agent exposes HTTP endpoints including /api/health, /api/filesystems and /api/pools, and accepts configurable port, scan interval and token settings.checked 14 Oct 2026
Authentication
Bearer-token authentication is optional; when configured, agent requests must include an Authorization header, while unconfigured agents serve data without authentication.checked 14 Oct 2026
Auto-discovery
Agents advertise over mDNS/Zeroconf so Home Assistant can discover them without manually entering an IP address.checked 14 Oct 2026
Discovery
Agents advertise over local-network mDNS/Zeroconf so Home Assistant can discover them without manual IP entry.checked 3 Oct 2026
Disk usage
Optional filesystem monitoring reports total, used and available space plus percentage for selected mountpoints through an API endpoint.checked 14 Oct 2026
Docker deployment
An independent Docker image documents amd64 and arm64 support, host networking for mDNS, configurable port 9099, 60-second scans and optional tokens.checked 14 Oct 2026
Docker security
The community Docker image requests SYS_RAWIO for SATA/SAS and SYS_ADMIN for NVMe instead of running fully privileged.checked 14 Oct 2026
Documentation depth
Documentation includes configuration examples, discovery troubleshooting, sensor definitions, attention logic, changelog entries and contribution guidance.checked 14 Oct 2026
Download security
Installers verify downloaded binaries with SHA256 checksums.checked 14 Oct 2026
Drive coverage
Its Attention Needed sensor monitors ATA, SATA, NVMe, and SAS drives and reports NO, MAYBE, YES, or UNSUPPORTED.checked 3 Oct 2026
Drive standby
Standby mode can avoid waking sleeping drives and serves cached readings with a data_as_of timestamp.checked 14 Oct 2026
Failure classification
The Attention Needed sensor classifies drives as NO, MAYBE, YES, or UNSUPPORTED using indicators such as reallocated, pending and uncorrectable errors.checked 14 Oct 2026
Installation
Linux and macOS use install.sh, Windows uses install.ps1, and Home Assistant installation is available through HACS or manual component copying.checked 14 Oct 2026
Integrations
The integration provides a service call with SMART data and assessments that can be passed to Google AI, ChatGPT, Claude, or Ollama.checked 3 Oct 2026
Licence
The repository is published under the MIT License.checked 14 Oct 2026
Limit: network discovery
mDNS discovery is link-local, so agents on different VLANs require an mDNS reflector.checked 14 Oct 2026
Limit: USB passthrough
USB enclosures that block SMART passthrough are reported as unsupported or unknown because the limitation is in the bridge hardware.checked 14 Oct 2026

Where it runs

App component
The separate Home Assistant OS app displays local and remote drives in a web-based Control Center and can feed the same integration entities, alerts and history.checked 14 Oct 2026
Limit: macOS telemetry
Device Statistics is always disabled on macOS because the operating system does not permit reading that log.checked 14 Oct 2026
Multi-machine monitoring
A separate lightweight agent can run on every monitored machine, with each drive represented as its own Home Assistant device.checked 14 Oct 2026
