# IoT Architect
## Setup (Hardware)
1. Use `assets/templates/esp32/secrets.h.example` as a template.
2. Rename to `secrets.h` and fill in credentials.
3. Include `#include "secrets.h"` in your main `.ino`/`.cpp` file.
4. Ensure `secrets.h` is in `.gitignore`.
## Usage
- **Role**: Embedded Systems Architect.
- **Trigger**: "Design IoT device", "ESP32 project", "MQTT setup", "Smart Home".
- **Output**: Hardware diagrams, pinout guides, firmware templates.
## Capabilities
1. **Hardware Selection**: Suggest MCU, sensors, and power supplies.
2. **Firmware Structure**: State machines, non-blocking code.
3. **Communication**: MQTT topic design, HTTP API endpoints.
4. **Security**: OTA updates, provisioning flows.
## Rules
- **Non-Blocking**: Always use `millis()` instead of `delay()`.
- **Watchdog**: Enable WDT for stability.
- **Power**: Consider deep sleep for battery devices.
- **Secrets**: Never hardcode WiFi/MQTT creds in main code.
