ClawdSense Skill

Real-time image capture and analysis from ClawdSense ESP32 dongle.

Quick Start

Start Services

# Terminal 1: Media receiver (accepts photo uploads from ESP32)
node ~/clawd/clawdsense-skill/scripts/media-receiver.js

# Terminal 2: Analyzer (monitors inbound folder, analyzes with Groq)
node ~/clawd/clawdsense-skill/scripts/analyzer.js

# Terminal 3: Health monitor (keeps both services alive)
node ~/clawd/clawdsense-skill/scripts/health-monitor.js

Usage

1. Send /photo command to ClawdSense via Telegram
2. Device captures and POSTs to media receiver (port 5555)
3. Analyzer detects new photo and analyzes with Groq Vision
4. Results printed to console

Architecture

Three Components

Media Receiver (port 5555)

• Accepts multipart/form-data uploads from ESP32
• Stores photos in ~/.clawdbot/media/inbound/
• Endpoints:
  • POST /inbound/photo - JPEG photos
  • POST /inbound/audio - WAV audio
  • POST /inbound/video - AVI video

Analyzer (real-time polling)

• Polls inbound folder every 500ms
• Detects new photos automatically
• Sends to Groq Vision API for analysis
• Uses pixtral-12b model for instant results

Health Monitor

• Checks both services every 30s
• Restarts if either dies
• Logs status to console

Performance

• Detection latency: ~500ms (polling interval)
• Analysis time: 1-3s (Groq API)
• Total end-to-end: ~2-5s from capture to results

Configuration

ESP32 Firmware Settings

Device must be configured with:

MEDIA_RECEIVER_URL = "http://localhost:5555"
or for public: "https://your-ngrok-url"

Groq API Key

Stored in environment:

export GROQ_API_KEY="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"

Troubleshooting

"Media receiver is DOWN"

• Check if port 5555 is in use
• Restart: node ~/clawd/clawdsense-skill/scripts/media-receiver.js

"No new photos detected"

• Is device sending to media receiver? Check device logs
• Is media receiver running? Curl http://localhost:5555/health
• Check inbound folder permissions

"Groq API errors"

• Verify API key is set
• Check account quota/billing
