Koada project (Open-source LED spectrum Controller & hydro automation)

Hey,

During the last two month, I worked hard building & optimizing our 2 Samsung F-Series build (3x3 & 4x4)

After some testing, we're quite happy with those two prototypes, but now we want to go a bit further. We need to create an easy way for us to manage more than ten lamps, so we decided to start a new automation grow system.

The name of our open-source & free project is Koada.

Our primary goal is to create a web-app (Working on Android/IOS & any recent web browser on your computer) who can manage a group of lamps powered by type B Meanwell drivers.

The main features will be:

1) Managing light schedule w/ PWM
2) Advanced spectrum controller (Dynamic spectrum)
3) Switching drivers On/Off completely with a connected power switch (relay)
4) Managing optional led modules (Far red for example).
5) Simulating sunset/sunrise w/ PWM
6) The ability to create different plant group to assign different light schedule/parameters & track different info (days since flowering, nutrition problem, days since last watering etc)
7) Managing watering with solenoid valves & wireless humidity sensor.
8 ) Conditional triggering, E.g Automatically adjusting light power to keep the grow space in a specific temperature range.

To achieve that, we will use the cheap Raspberry Pi (Model 3B for Wifi/Bluetooth support) computer with a PWM controller hat. (50-100$ depending on where you live)

We also have some mid-term goals:


1) Managing hydroponics installation (PH/TDS)
2) Creating an alarm & log system with temperature/humidity sensor to prevent problems, monitor & improve grow routine
3) Selling fair-priced kit (Installed raspberry pi with the proper hat, solenoid valve, PWM cable & connector, etc)

I will keep this post updated with the project's progression.

This project is based in Switzerland.

We expect our first release for mid-October.
