433toMQTTto433 - Bidirectional ESP8266 NodeMCU gateway between RF 433Mhz signal and MQTT

The goal  is to act as a gateway between 433Mhz sensors and a MQTT broker or between the MQTT broker and 433Mhz actuators, It enables to:
receive MQTT data from a topic and send RF 433Mhz signal corresponding to the received MQTT data publish MQTT data to a different topic related to received 433Mhz signal 
It can be an interesting part in an home automation system so as to interface sensors and actuators (wall sockets) with software like openhab.

List of compatible sensors here

The interest of putting this gateway to an ESP8266 and not on a raspberry pi is to be able to manage security actions at gateway level (power on a siren, cut power to certain devices) following RF data received by sensors without being dependent to the PI for security related actions.

[EDIT] all infos are now centralized into the github repository take a look at it you will find up to date info about OpenMQTTGateway
