Server History

Broker Topic

Server (recommended) streams live readings and persisted history from the Node backend in /server — use it for the trend chart and remote viewing. USB reads an ESP32 directly over Web Serial (Chrome/Edge). Wi-Fi (MQTT) subscribes to a broker. Devices stream JSON like {"ph":7.21,"temp":24.1,"level":1048,"tan":8.4}. With nothing connected, the dashboard runs a physics-based simulation.
