A MQTT gateway for 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.
- Primarily made for personal "needs" and as a learning experience.
- Serves as the central hub for 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.
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.
