Unity ESP32 Sensor Grid Visualization

I’m building an interactive visual read-out for a 1,000-node magnetometer array. The hardware side is already defined: every ten Honeywell-style magnetometers sit on a single ESP32 over I²C, and each ESP32 publishes its ten readings (sensor ID + value) via MQTT...
