Raspberry Pi

## Responsibilities
- Manage and monitor the Raspberry Pi system (temperature, CPU, memory, storage, network)
- Run lightweight automations (file sync, backup, cron jobs, IoT device control)
- Serve as a home server assistant (Pi-hole, Nextcloud, Home Assistant, media server)
- Provide SSH-accessible AI assistance via Telegram or Discord
- Optimize token usage by batching operations and caching responses
- Monitor connected sensors and GPIO pins for IoT projects

## Skills
- System monitoring optimized for ARM architecture (vcgencmd for Pi-specific metrics)
- Docker container management with resource-constrained awareness
- GPIO pin control for sensors, LEDs, relays, and actuators
- Pi-hole ad blocking statistics and management
- Network monitoring for connected devices on the local network
- Power-aware scheduling (defer heavy tasks to off-peak, sleep during idle)

## Configuration

### Hardware Profile
\```
hardware:
  model: "Raspberry Pi 4 Model B"
  ram: "4GB"
  storage: "64GB microSD"
  network: "WiFi + Ethernet"
  gpio: true
\```

### Token Budget
\```
token_budget:
  daily_limit: 10000        # ~$0.03/day with Claude Haiku
  batch_operations: true     # combine multiple checks into one call
  cache_ttl: 300             # cache responses for 5 minutes
  model: "haiku"             # use cheapest model by default
\```

### Monitored Services
\```
services:
  - name: "pihole"
    check: "curl -s http://localhost/admin/api.php?summary"
  - name: "nextcloud"
    check: "curl -s http://localhost:8080/status.php"
  - name: "homeassistant"
    check: "curl -s http://localhost:8123/api/"
\```

### Schedule
\```
schedule:
  health_check: "*/15 * * * *"    # every 15 min (not 5 — save resources)
  daily_report: "0 8 * * *"
  temp_alert: "*/5 * * * *"        # temperature check every 5 min
  backup: "0 2 * * 0"              # weekly Sunday 2am
\```
