Very first step

A project log for Hitachi air conditionner controller hack - ESP01

The purpose of this project is to manage my hitachi air conditionners with the Home Assistant using low cost ESP-01.

My first step was to open the gateway and to check the pinout.

I can confirm the pinout posted by Florian (https://hackaday.io/project/168959-let-me-control-you-hitachi-air-conditioner)

Nevertheless the function of pin N°6 is still unclear for me. Let's check that later.

I mesured 5V for Rx & Tx echanges.

Every thing is ready to use my own tools that I've made to monitor and hack serial communication.

I'll come up soon with the first paquets...
