WORK IN PROGRESS

Motivation

I want to build a simple grow system, which I can power by my off-grid 12V solar system. So this project is limited to a small 40x40x120 tent for one plant with a 50W 12V grow LED light.

As I did it for my solar system, the measurements of this project will be shown on my website. For that a REST API is planned.

I want to automate as much as possible which makes sense and is easy to build.

Features / ToDo List

  • Measure values ✅
    • Humidity ✅
    • soil moisture ✅
    • temperature ✅
    • water level for water tank ✅
  • LED grow light control (on/off, dimming, max. 12V 50W load ) ✅
    • You can of course use a relais as well, if you want to drive 220V lights ✅
  • fan control (on/off, (PWM?) max 1A) 🔵
  • pump control for automatic watering (max 1A) 🔵
  • Web UI and REST API for data and controlling 🔵
    • simple web ui ✅
    • REST API 🔴
    • Send notifications with web call (e.g. for mastodon) 🔴
    • predefined grow profiles 🔵
    • persistend data ✅
      • Start of Grow ✅
      • day of grow 🔵
      • grow profile
        • watering amount per week 🔵
        • light cycle ✅
      • wifi settings ✅
      • settings in general ✅
  • Easy to build and use for beginners (i hope so!) ✅
    • PCB layout to order from manufacture (jlcpcb or pcbway) ✅
    • easy to build up on a perfboard ✅
    • easy to etch pcb ✅
    • easy to access and modify ✅
    • low cost as possible! ✅
