        MQTT-radio-gateway      

    
   



A MQTT gateway for [radio-nodes](https://github.com/Peppson/radio-nodes) (or any other *NRF24L01*-based project) and generic 433Mhz radio devices,  

such as power sockets, lights, etc.  

Written for the ESP32 microcontroller using PlatformIO.

  

## Project Overview

- Primarily made for personal "needs" and as a learning experience.   

- Serves as the central hub for [radio-nodes](https://github.com/Peppson/radio-nodes).

- Takes in MQTT and sends the data via 2.4Ghz radio to the appropriate node,  

maybe to turn on the coffeemaker, water plants, open blinds etc.

- Relays sensor data from nodes to InfluxDB.

  

## PCB - ESP32 Shield

Made a custom PCB to fit ontop of an ESP32 Uno development board.   

Integrates a *LAN8720* ethernet module, a *NRF24L01* radio transceiver and some extra I/O in a compact format.
