CyberSecurity guy doing offensive for greater good.

For the last 20 years I've been struggling with perception that cybersecurity is underestimated, not clear for regular humans and expensive. Lucky for all of us this isn't a case anymore.



This project is based on NodeMCU board. It's running on ESP8266 chip which perfectly fits basic requirements for affordable and flexible deployment of "inteligence" into your home. Modules are capable of creating WiFi network (connectig to existing Wireless network and creating AP simultanously). They are registering to Control Server which can check state of their inputs, set output state, upload new configuration and even update their firmware.


Control Server for ESP-Module

This is a work-in-progress version of Control Server which can control and manage ESP-Modules. The idea is to give user a possibility to instlal this apllication on some small device like Raspberry Pi or BeagleBone.
