It a project initiali made by n3odym3. I just added the MQTT credentials fonctions.

This module allows to decode and replicate IR remotes while being remotely controllable by MQTT.

Tutorial video (in french) :

At the first boot or if the WiFi is unavailable, the ESP will create an accespoint named IR-CLONER.

Connect to this AP using your smartphone or computer and go to http://192.168.4.1

The WiFI and MQTT are not mandatory, the device can be used with the AP and ESPUI interface

When a remote control is detected the raw sequence is decoded and can be retrieved from :

• Serial port : baud rate = 115200 by default
• ESPUI interface : Debug tab and IR CMD pannel
• MQTT : MQTT Topic out

You can send an IR command using :

• Serial port : paste the raw sequence array
• ESPUI interface : paste the raw sequence array, press ENTER and clic on the SEND button
• MQTT : MQTT Topic in
