IR Gateway

Introduction

This small box has been my IR gateway for many years and it will likely serve many years to come. It started out using Nodo firmware (the ESP module socket wasn't there yet) but is has been replaced with a small RFLink edition that runs on Atmage328P. The ESP socket was added and it runs ESP Easy Mega edition.

The module has always worked autonomous so it does not depend on other controllers. It has always been rock solid stable.

It used 3.5" jack plugs to connect two IR sensors that are located in other rooms (living and bedroom). These are the two jack connectors at the bottom side. The right side jack plug is for serial, to upgrade the RFLink firmware when needed.

Hardware

Atmega 328P (but any Arduino Uno, Pro mini will also work) IR receiver 433MHz transmitter ESP8266 ESP01 module (1MB Flash version)
