This eBUS LoRaWAN Gateway bridges heating systems using the eBUS protocol with long-range wireless connectivity via LoRaWAN. The gateway reads data from eBUS-compatible boilers and thermostats, then transmits the information to a LoRaWAN network for remote monitoring and control.

The guide provides a complete parts list, wiring diagram for connecting the ESP32 to an eBUS interface module and LoRa transceiver, and step-by-step assembly instructions. Firmware code handles eBUS communication, LoRaWAN protocol implementation, and data parsing, allowing makers to integrate legacy heating systems into modern IoT networks.
