Hi everyone, I’m working on an IoT setup where ESP32 modules use ESPNOW to communicate locally (multi-node mesh). Then, one node publishes aggregated data to an MQTT broker via HiveMQ. I used this ESP‑NOW tutorial as a starting point for the local peer‑to‑peer protocol: https://www.theengineeringprojects.com/2022/01/esp-now-protocol-with-esp32-and-esp8266.html .It helped me grasp mesh setup and pairing logic.
My main question: how should I structure topics to clearly differentiate sensor-origin and mesh-node routing, while maintaining scalability and minimizing broker load? Any real-world examples or naming conventions you’d recommend?
