Enhancement: Environmental Safety Features to Prevent Overheating

Problem Description

During extensive benchmarking of a Bitaxe fleet, we encountered dangerous overheating scenarios that could have caused permanent hardware damage:

• ThorGamma: Reached 66°C+ (thermal protection activated)
• LokiSupra: Hit 68.9°C (critically dangerous)
• Root Cause: Hot ambient conditions + inadequate environmental monitoring

The current benchmark script lacks environmental awareness, making it risky in warm conditions or poorly ventilated areas.

Proposed Solution

We've developed Environmental Safety Extensions that add:

🌡️ Pre-Benchmark Environmental Assessment

• Ambient temperature/humidity checking
• Safety threshold evaluation
• Risk-based benchmark limits
• User-guided safety decisions

🛡️ Temperature-Aware Benchmarking

• Dynamic voltage/frequency limits based on ambient conditions
• Auto-abort on dangerous temperatures
• Environmental metadata in results
• Conservative test matrices for hot conditions

🔧 User-Friendly Safety Interface

• Shell script with pre-flight checks
• Device connectivity verification
• Automated logging and error handling
• Clear safety status indicators

Implementation Details

New Files Proposed:

• environmental_check.py - Core safety assessment module
• safe_benchmark.py - Enhanced benchmark runner with environmental integration
• run_safe_benchmark.sh - User-friendly script wrapper
• Updated README.md - Safety guidelines and usage

Safety Thresholds:

• < 24°C: Full performance testing safe
• 24-26°C: Reduced voltage limits (1200mV max)
• 26-28°C: Conservative settings only (1150mV max)
• > 28°C: Benchmarking not recommended

Temperature Limits:

• Ambient-based device limits: Prevent overheating before it occurs
• Auto-abort protection: Stop tests if temperatures exceed safe thresholds
• Cooling recommendations: Guide users to safe operating conditions

Benefits to Community

1. Hardware Protection: Prevents expensive damage from overheating
2. Safer Benchmarking: Especially important for new users
3. Environmental Awareness: Makes benchmarking practical in various conditions
4. Professional Safety: Brings enterprise-level safety practices to hobbyist mining
5. Better Data: Environmental metadata improves result validity

Real-World Testing Evidence

Our safety extensions have been tested on a 3-device fleet:

• Bitaxe Supra (LokiSupra)
• 2x Bitaxe Gamma (ThorGamma, OdinGamma)

Successfully prevented multiple overheating incidents and enabled safe operation in challenging thermal conditions.

Backward Compatibility

• Existing functionality remains unchanged
• New features are opt-in
• Original script continues to work as before
• No breaking changes to current users

Would you be interested in a pull request implementing these safety features? We believe this would significantly improve the safety and reliability of Bitaxe benchmarking for the entire community.

Hardware safety should be the top priority in any benchmarking tool. 🛡️
