🚀 ALIE: Artificially Linked Intelligent Entity

ALIE High-Level Architecture

📖 Table of Contents

💡 Overview

ALIE (Artificially Linked Intelligent Entity) is a full-stack, production-grade IoT automation platform designed for real-time, secure, and intelligent control of smart environments. Unlike typical DIY projects, ALIE is engineered as a robust product, blending advanced embedded systems, cloud integration, and immersive user interfaces to deliver seamless, multi-modal control and monitoring.

📝 Introduction

ALIE is a next-generation smart automation system built on the ESP32 platform, leveraging FreeRTOS, MQTT, and end-to-end encryption. It supports voice, touch, web, mobile, and even BCI (Brain-Computer Interface) controls, with real-time cloud synchronization and OTA updates. The system is designed for reliability, extensibility, and immersive user experience, making it suitable for both home and industrial automation.

🏆 What Sets ALIE Apart

  • Product-Grade Engineering: Not just a project, but a scalable, maintainable, and customizable product.
  • Multi-Modal Control: Voice (Alexa/Google Home), NFC/RFID, touch, web, mobile, and BCI.
  • Real-Time & Secure: Fast response (25ms latency reduction), end-to-end encryption, OTA updates.
  • Cloud-Connected: Bi-directional sync with Firebase, remote scheduling, and monitoring.
  • Immersive UI: 3D React dashboard, live camera streams, music playback, and more.
  • Smart & Resilient: Auto-resynchronization, deep sleep for energy saving, and robust error handling.
  • Custom Hardware: 3D-printed casing designed in Fusion 360 and Blender.

⚙️ How It Works

  1. Device boots up and connects to WiFi (ad-hoc or WAN).
  2. Sensors and relays are initialized; FreeRTOS tasks manage device logic.
  3. User interacts via web/mobile/voice/touch/BCI.
  4. Commands are processed locally or sent securely to the cloud (Firebase).
  5. Device state is updated in real-time across all interfaces.
  6. Scheduling, automation, and alerts are handled via cloud and local logic.
  7. OTA updates and error handling ensure reliability and security.

🧩 Workflow

  1. Setup: Device is configured via web/mobile interface or NFC.
  2. Control: User can control appliances, monitor sensors, and schedule tasks.
  3. Sync: All changes are synced with Firebase for remote access and backup.
  4. Automation: Scheduled events and smart triggers automate environment.
  5. Monitoring: Real-time dashboard provides immersive visualization and alerts.
  6. Energy Saving: Device enters deep sleep when idle, wakes on event.

📦 Setup & Installation

Hardware

  1. Assemble ESP32, relays, sensors, and optional NFC/RFID modules.
  2. Print and assemble the custom casing (see images/hardware/).
  3. Power up the device.

Firmware

  1. Install PlatformIO in VSCode.
  2. Clone this repo and open in VSCode.
  3. Configure platformio.ini as needed.
  4. Build and upload firmware to ESP32: 
    pio run --target upload
  5. Monitor serial output for debugging and configuration info: 
    pio device monitor

Configuration

  • Edit src/config/app_config.h to set up WiFi, Firebase, and other parameters.
  • Use src/config/wifi_config.h for WiFi credentials (SSID, password).
  • Configure Firebase in the Firebase console; download google-services.json and place it in the src directory.

📚 Usage

  • Web Interface: Access the 3D dashboard, control devices, and monitor status at http://<device_ip>.
  • Mobile App: Use the Blynk app to control devices and receive notifications.
  • Voice Control: Integrate with Alexa or Google Home for voice commands.
  • Touch Control: Use the touch sensors on the device for local control.

🧪 Deployment & Testing

  • For production, use a reliable power source and consider a UPS for backup.
  • Test all functionalities, including OTA updates, cloud sync, and automation.
  • Monitor system performance and logs for any anomalies.
