Distributed File System

Written in Java and using the Netty Async I/O framework. This Distributed File System is highly performant, scalable, redundant and available.

It works with a disassembled garage remote, a relay with wires bridging the button on the remote to simulate a button press and a ESP32 with a webserver to control the relay.
