Lightning Node Online

The AS3935 lightning detector becomes a dedicated ESP32 node with diagnostics, event classification and backend ingestion.

A dedicated node for lightning events

The lightning detector was separated into its own ESP32 node, focused on one purpose: detecting and reporting AS3935 events.

This makes the node easier to diagnose and keeps the responsibility clear.

What the node sends

The node reports event type, distance when available, energy when available, RSSI, uptime and diagnostic information.

Events are classified as lightning, disturber, noise or unknown, instead of being treated as generic alerts.

Backend integration

Events are sent to the observatory backend and stored in a dedicated lightning events table.

This allows future historical views, statistics and correlation with weather conditions.
