GrowNode is a vertical framework to build esp32 based devices targeted to growing plants in a controlled environment.

[September 2022] from release 0.8.0, GrowNode supports HOMIE 4.0.0 as messaging standard! We think this is a great step in standardization, making the boards able to be discovered and talk with most popular IoT controllers (OpenHab, Home Assistant, Node-RED etc.)

Grownode is targeted for whoever has the need to build an automatic growing system, from DIY home growing to more advanced farming solutions.

This platform will facilitate the hardware and software design and implementation phase, by giving you a ready made set of functionalities, materials and knowledge base.

In order to startup a basic prebuilt system, you just need to follow the instructions in boards section.

If you want to play hard and develop your own customized system, a basic knowledge of C programming, ESP-IDF development environment, and electrical engineering is required.

You can use GrowNode to build a system that warns you when humidity and temperature on a plant is outside determined range, by blinking a LED:

You can then add network connectivity to a server and have your board warns you on your PC or mobile phone, and change the system parameters via a simple interface.

GrowNode has a growing list of supported sensors and actuators, in order to build a more sophisticated system. You can add sensors, motors, lights, pumps, everything needed to build your own solution customized to your needs.

Grownode is born having in mind IoT distributed environments. You can add nodes to your system and those nodes will easily talk between each other, acting as a unique orchestrated platform, with no limits over its scalability.
