Production-Grade Open Source IoT Hydroponic Control System

---

HydroponicOne is a robust, modular, and professional-grade hydroponic monitoring and control system. It aims to bridge the gap between hobbyist DIY setups and expensive industrial automation. Featuring a modern tech stack including MQTT, InfluxDB telemetry, and a sleek React-based dashboard.

✨ Features

• Real-Time Environment Monitoring: High-precision tracking of pH, EC, water level, temperature, and humidity.
• Automated Actuator Control: Smart relays for dosing pumps, main circulation, grow lights, and ventilation.
• Secure Architecture: Async MQTT with TLS, offline robust modes, and RSA-2048 Signed OTA updates.
• Edge-First Local Dashboard: Lightning fast React SPA communicating over real-time WebSockets to a Fastify backend.
• Enterprise Data Management: PostgreSQL for persistent config state and InfluxDB for time-series telemetry.

⚡ Quickstart & Installation

1. Clone the repository

git clone https://github.com/40rbidd3n/Hydro0x01.git
cd HydroponicOne

2. Setup Backend Configure the environment and seed the database.

cd backend
npm install
cp .env.example .env
# Edit .env with your DB credentials and a secure JWT Secret
npx prisma db push
npm run dev

3. Setup Frontend

cd ../frontend
npm install
cp .env.example .env
npm run dev

4. Build & Flash Firmware Review the Hardware Setup and connect your sensors to the ESP32.

cd ../firmware

# IMPORTANT: Clone the configuration template before compiling
cp include/config.example.h include/config.h
# Edit include/config.h with your network and MQTT details

# Edit platformio.ini to choose your hardware environment (e.g., env:esp32_dht_bmp)
pio run -t upload
