🏃‍♂️ Quick Start

Prerequisites

• Python 3.9+ (for Imgflip integration)
• ESP32 board with 2.4" TFT display
• Arduino IDE for firmware flashing
• Internet connection (for dynamic Imgflip triggers)

1. Clone & Setup

git clone https://github.com/dentity007/bongo_cat_monitor_remix.git
cd bongo_cat_monitor_remix

Run (Python desktop app)

# from repo root
python -m venv .venv
source .venv/bin/activate  # Windows: .venv\Scripts\activate
pip install -r requirements_app.txt  # or: pip install -e .
python bongo_cat_app/main.py

Project layout

• bongo_cat_app/ – Canonical Python desktop app (Tk/pystray)
• bongo-cat-electron/ – Optional Electron UI (not required to run the Python app)

2. Imgflip Setup (Optional)

The app works without any API configuration, but for dynamic triggers:

1. No authentication required! - Imgflip API is free and doesn't need credentials
2. Automatic setup - The app will automatically fetch trending memes on startup
3. Fast loading - 30x faster than Reddit integration (loads in <1 second vs 10-30 seconds)

Dynamic triggers include (20 total, updated daily):

• "drake" → Drake Hotline Bling meme
• "bernie" → Bernie Sanders "I am once again asking"
• "epic" → Epic Handshake meme
• "disaster" → Disaster Girl meme
• "gru's" → Gru's Plan meme
• "batman" → Batman Slapping Robin meme
• "anakin" → Anakin Padme 4 Panel meme
• And 13 more trending memes updated daily at midnight!

3. ESP32 Setup

1. Open firmware/bongo_cat_monitor.ino in Arduino IDE
2. Install required libraries (TFT_eSPI, LVGL)
3. Upload to your ESP32 board

4. Hardware Monitoring Setup (Optional - Windows Only)

For advanced CPU/GPU temperature monitoring with privacy protection and API resilience:

1. Install Python dependencies:

   pip install -r bongo_cat_app/requirements_hardware.txt

2. Enable in settings (requires explicit consent):

   • Launch the app and go to Settings → Advanced tab
   • First: Check "I consent to hardware temperature monitoring"
   • Then: Check "Enable hardware temperature monitoring"
   • Provider: Select "auto" (recommended) or specific provider
   • Mode: Keep "GPU-only mode" checked for least privilege (recommended)
   • Test: Click "Test Sensors" to verify connectivity
   • Check "Show CPU Temperature" and/or "Show GPU Temperature" in Display tab

Privacy & Security:

• ✅ Opt-in only: Must explicitly consent before enabling
• ✅ Least privilege: GPU-only mode doesn't require admin rights
• ✅ Local only: No data is transmitted externally
• ✅ Test before use: Verify sensor connectivity works
• ✅ API Resilience: Circuit breaker pattern prevents app crashes from sensor failures

Supported Providers:

• auto: Automatically detects best available provider
• lhm_http: LibreHardwareMonitor (requires admin for CPU, runs as separate process)
• nvml: NVIDIA Management Library (GPU-only, no admin needed)

API Resilience Features:

• TTL Caching: Sensor data cached for 60 seconds to reduce polling overhead
• Circuit Breaker: Automatically disables monitoring after repeated failures
• Automatic Recovery: Attempts to re-enable monitoring after cooldown period
• Fallback Values: Shows "N/A" instead of crashing when sensors unavailable

Troubleshooting:

• If "Test Sensors" fails, try different provider or check permissions
• GPU-only mode works without administrator privileges
• CPU monitoring requires admin rights on Windows
• Check logs for circuit breaker state and cache hit/miss ratios

5. API Resilience Features

The application includes enterprise-grade resilience patterns to ensure reliable operation:

Circuit Breaker Pattern:

• Automatically disables external API calls after repeated failures
• Prevents app crashes from network issues or API downtime
• Automatically attempts recovery after cooldown period

TTL Caching System:

• Caches API responses for 60 seconds to reduce network load
• Falls back to stale data when fresh data unavailable
• Persists cache to disk for faster startup

Fallback Mechanisms:

• Static triggers always available when dynamic API fails
• Graceful degradation maintains core functionality
• Comprehensive error handling prevents crashes

Monitoring & Telemetry:

• Built-in metrics for cache hits/misses, API success/failure rates
• Circuit breaker state monitoring
• Debug logging for troubleshooting

6. Test Triggers

• Type "bullet" → Top Gun reference!
• Type "drake" → Drake Hotline Bling meme
• Type "bernie" → Bernie Sanders meme
• Type "epic" → Epic Handshake celebration
• Type "batman" → Batman Slapping Robin meme
• Type "gru's" → Gru's Plan meme
• And 15 more dynamic triggers updated daily!
• Type "wow" → "Mind blown! 🐱"

🆘 Troubleshooting

Common Issues

Reddit Authentication Failing

❌ Error: received 401 HTTP response

Solution: Ensure Reddit app is configured as "script" type with redirect URI http://localhost:8080

ESP32 Not Connecting

No ports found—plug in ESP32!

Solution: Check USB connection and ensure correct ESP32 board is selected in Arduino IDE

Python Dependencies Missing

ModuleNotFoundError: No module named 'praw'

Solution: Run pip install -e . in your activated virtual environment

Virtual Environment Issues

python3: command not found

Solution: Install Python 3.9+ and recreate virtual environment

Hardware Monitoring (Windows)

Default: OFF and least-privilege (no admin needed). Enable it in Settings → Hardware Monitoring.

Providers

• LibreHardwareMonitor (recommended): Open LibreHardwareMonitor → Options → Remote Web Server → Enable (default http://localhost:8085). The app reads temps from this local JSON endpoint; no admin for the app.
• NVML (NVIDIA GPUs): Install pynvml (pip install nvidia-ml-py3). GPU temperature is available without admin.

Common issues

• "Sensor probe failed" with Connection refused: Start LibreHardwareMonitor and enable the Remote Web Server.
• CPU temperature missing: Some paths require admin in third-party tools. Use LHM HTTP or switch to GPU-only.
• Do I need admin? No for this app's default paths. Only run elevated if you explicitly choose a provider that requires it and understand the scope.
