Hey everyone

I've been working on a personal project for a while and finally made it public -it's a production-grade, open-source hydroponic control system called HydroOne

The goal was to build something that sits between:

– basic DIY Arduino setups

– and expensive commercial controllers

What it does

• Real-time monitoring of pH, EC, water level (using ultrasonic sensor), temp, humidity
• Automated control of:
  • dosing pumps (pH up/down, nutrients)
  • main water pump
  • grow lights & fan
• Remote control + live dashboard

Tech side (for those interested)

• ESP32 firmware (C++)
• MQTT (real-time telemetry)
• InfluxDB (time-series data)
• PostgreSQL (config & state)
• Fastify backend (Node.js)
• React dashboard (real-time UI)
• Secure OTA updates (RSA-signed firmware)

Most guides I found were either:

• too basic
• or not scalable

So I wanted something: modular, secure and actually usable long-term

I'd really appreciate:

• feedback from experienced growers
• ideas for improvements
• or even contributors if someone finds it useful

Thanks
