I maintain this and other Home Assistant add-ons in my free time: keeping up with upstream changes, HA changes, and testing on real hardware takes a lot of time (and some money). I use around 5-10 of my >110 addons so regularly I install test machines (and purchase some test services such as vpn) that I don't use myself to troubleshoot and improve the addons

If this add-on saves you time or makes your setup easier, I would be very grateful for your support!

About

Scrutiny is a Hard Drive Health Dashboard & Monitoring solution, merging manufacturer provided S.M.A.R.T metrics with real-world failure rates. This addon is based on the docker image from linuxserver.io.

Features :

SMART monitoring
Automatic addition of local drives
Hourly updates
Ingress
Automatic upstream updates

Configuration

Webui can be found at http://homeassistant:8080 or through the sidebar using Ingress. Configurations can be done through the app webUI, except for the following options. It automatically mounts all local drives.

Note: Enable full access only if encountering issues. SMART access should work without full access in all scenarios.

Options

Option	Type	Default	Description
`Updates`	list	`Hourly`	Update schedule (Quarterly/Hourly/Daily/Weekly/Custom)
`Updates_custom_time`	str		Custom update interval (e.g., "5m", "2h", "1w", "2mo")
`TZ`	str		Timezone (e.g., `Europe/London`)
`Mode`	list		Operating mode (Collector+WebUI or Collector only)
`COLLECTOR_API_ENDPOINT`	str		Collector API endpoint URL
`COLLECTOR_HOST_ID`	str		Host identifier for collector
`SMARTCTL_COMMAND_DEVICE_TYPE`	list		Device type for SMARTCTL commands
`SMARTCTL_MEGARAID_DISK_NUM`	int		MegaRAID disk number
`expose_collector`	bool		Expose collector port externally

Example Configuration

Updates: "Daily"
Updates_custom_time: "12h"
TZ: "Europe/London"
Mode: "Collector+WebUI"
COLLECTOR_API_ENDPOINT: "http://localhost:8080"
COLLECTOR_HOST_ID: "home_assistant"
SMARTCTL_COMMAND_DEVICE_TYPE: "auto"
expose_collector: false

Custom Scripts and Environment Variables

This addon supports custom scripts and environment variables:

Custom scripts: See Running Custom Scripts in Addons
env_vars option: Use the add-on env_vars option to pass extra environment variables (uppercase or lowercase names). See https://github.com/alexbelgium/hassio-addons/wiki/Add-Environment-variables-to-your-Addon-2 for details.

Installation

The installation of this add-on is pretty straightforward and not different in comparison to installing any other add-on.

Add my Hass.io add-ons repository to your home assistant instance.
Install this add-on.
Click the Save button to store your configuration.
Set the add-on options to your preferences
Start the add-on.
Check the logs of the add-on to see if everything went well.
Open the webUI (Ingress based) and adapt the software options

Integration in home assistant

Integration with HA can be done with the rest platform in configuration.yaml.

The API is available on Home Assistant's internal network even when the port is not exposed. Use the add-on's internal domain name (http://db21ed7f-scrutiny:8080) to query it from Home Assistant or other add-ons. If you need to reach the API from your local network, expose the port in the add-on options and replace the domain with your Home Assistant IP address.

Two types of API endpoints are available:

Summary data: http://db21ed7f-scrutiny:8080/api/summary
Detailed data: http://db21ed7f-scrutiny:8080/api/device/WWN/details

For the detailed data, wwn can be found for each HDD within the Scrutiny app. For example: http://db21ed7f-scrutiny:8080/api/device/0x50014ee606c14537/details

Example to get data from the first hdd.
