Gateways can be configured to send an ESP-NOW transmission either to the serial port using JSON, another ESP-NOW gateway, or broadcast it via LoRa PHY. An incoming transmission from the serial port can also be routed to the same interfaces, with the addition of MQTT.
## Getting Started
To use FDRS with Node-Red and MQTT you'll need two ESP devices (gateways) that are connected via UART, plus additional ESP devices with sensors connected.

**Sensors** can use the [“fdrs_sensor.h”](https://github.com/timmbogner/Farm-Data-Relay-System/tree/main/FDRS_Sensor2000) file to set up the device and send FDRS data via ESP-NOW and/or LoRa.
