/*
  OpenMQTTGateway  - ESP8266 or Arduino program for home automation

   Act as a gateway between your 433mhz, infrared IR, BLE, LoRa signal and one interface like an MQTT broker
   Send and receiving command by MQTT

  This gateway enables to:
  - publish MQTT data, which are received from RF433Mhz signal (based on WeatherStationDataRx)

    Library for read weather data from Venus W174/W132, Auriol H13726, Hama EWS 1500, Meteoscan W155/W160
