Libre Hardware Monitor

S.C.O.R.E. → Safety → Security

Overview

Libre Hardware Monitor provides a comprehensive solution for tracking the performance metrics of your computer hardware. By monitoring CPU temperatures, GPU usage, fan speeds, and other vital statistics, users can ensure their systems are running efficiently and safely, preventing overheating and potential hardware failures.

Benefits

• Early detection of overheating issues to prevent hardware damage
• Real-time performance tracking for optimal system management
• Enhanced awareness of system resource usage, aiding in troubleshooting

Intent

The purpose of the Libre Hardware Monitor capability is to gather and display critical hardware metrics from your computer. This enables users to maintain system health and performance by proactively addressing any anomalies.

Preconditions

• Libre Hardware Monitor software installed on the computer.
• Home Assistant integration configured to access monitoring data.
• Network connection to report metrics back to Home Assistant.
• Home Assistant installed and configured.
• Integration available and authenticated: Zigbee2MQTT.
• Device installed and reachable: Energy Monitoring.

Actors

• Homeowner managing their home office setup
• Family member using a shared computer
• Tech-savvy guest monitoring system performance

Trigger

The capability is triggered by the software polling the hardware sensors at defined intervals, or by user requests for real-time data.

Workflow Description

1. Initialize Monitoring

Libre Hardware Monitor starts reading data from the computer’s hardware sensors.

2. Poll Hardware Data

The system polls sensors for CPU temperature, GPU usage, and fan speeds at regular intervals.

3. Analyze Data

The software analyzes the collected data to determine if any metrics exceed safe thresholds.

4. Trigger Alerts

If any critical values are detected, alerts are generated and reported to Home Assistant.

5. User Notification

Home Assistant notifies the user through preferred channels (mobile app, email, etc.).

Postconditions

After monitoring, users receive alerts if any metrics are concerning, allowing them to take necessary actions to protect their hardware.

Optional Enhancements

• Integrate with smart thermostats to adjust room temperature based on hardware load
• Enable historical data logging for trend analysis over time
• Add remote access to monitor hardware metrics from outside the home
