/*
OpenMQTTGateway - ESP8266 or Arduino program for home automation
Act as a wifi or ethernet gateway between your 433mhz/infrared IR signal/BLE and a MQTT broker
Send and receiving command by MQTT
This gateway enables to:
- publish MQTT data to a different topic related to BLE devices rssi signal
- publish MQTT data related to mi flora temperature, moisture, fertility and lux
- publish MQTT data related to mi jia indoor temperature & humidity sensor
