# CanGrow

|
An easy to use DIY grow controller firmware (for cannabis).
|
|
|
|
|
|
|

# WORK IN PROGRESS
|
|
|
|
## Motivation
|
|
I havn't found an already existing grow controller project within the ESP / Arduino Core eco system which
|
|
met my personal requirements.
|
|
Those are an easy DIY, using low cost parts, Arduino Core sourcecode to hack own things together, having a WebUI, grab some Metrics for monitoring, standalone and my very special need that the Hardware should run completely with 12V.
|
|
|
|
### Update 14.09.2024 - Code Rewrite v0.2
|
|
|
|
I took some "summer break" from the project, and had the opportunity to talk to different people about it.
|
|
My conclusion at this point is, that the focus of this project is not the Hardware, it came out that it should be the software.
|
|
So I decided to completely rewrite the code from 0 - with recycling some parts of it.
|
|
Goal of the Rewrite is that the Firmware becomes more independent of the hardware used. It has to support both ESP8266 and ESP32
|
|
and let the user decide at which pin which output, sensor or whatever will be connected to. Like done in the [Tasmota](https://github.com/arendst/Tasmota) Firmware, I also want to support "Hardware Templates" which come with presets for PCBs like the one I created.
|
|
|
|
**Checklist for v0.2 Firmware**
|
|
- Support ESP8266 and ESP32
|
|
- AsyncWebserver instead ESP8266Webserver
|
|
- LittleFS instead of EEPROM()
|
|
- deliver static HTML, dynamic Stuff with Javascript
|
|
- (or is there a better way? please tell me!)
|
|
- Free configurable outputs
|
|
- Main outputs for Light, Air, Water
|
|
