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.
