A CC1101 handles RF reception, the ESP32-S3 processes the protocol, and the W5500 module provides a stable Ethernet link. Although a Wi-Fi version (ramses_esp) already exists, this Ethernet-only design was created for users who need maximum reliability and a true plug-and-play gateway—a device you configure once, connect to Ethernet and power, and depend on continuously…
