/*  
  OpenMQTTGateway  - ESP8266 or Arduino program for home automation 

   Act as a wifi or ethernet gateway between your 433mhz/infrared IR signal  and a MQTT broker 
   Send and receiving command by MQTT
 
  This gateway enables to:
 - publish MQTT data to a different topic related to received 433Mhz signal DIO/new kaku protocol

    Receiving cannot be used with this gateway as it is not currently compatible with pubsubclient, emitting can be used with both RF gateway on the same program.
    Note that repeater and acknowledgement are not available with this gateway.
    -->So as to know the code of your devices use ShowReceivedCode from https://github.com/1technophile/NewRemoteSwitch
