LoRa Gateway Log Visualizer

Overview

Browser-only viewer for LoRa gateway logs — drop in a .log or .txt file and get instant statistics, packet decoding, and time-series charts. Nothing leaves the page; parsing and visualization both happen client-side, which matters when you're staring at production traffic on a customer site.

Loads multiple files at once, lets you toggle visibility per file, and remembers human-readable labels assigned to device addresses across sessions. Built as plain HTML + vanilla JS + Chart.js — no build step, no framework, drop the folder onto a static host and it runs.

Highlights

• ▸Multi-file loading with per-file toggle and persistent device labels
• ▸Interactive charts: RSSI, SNR, rolling PER, frequency-channel map
• ▸Packet inspector with raw payload and frame-counter gap detection
• ▸Side-by-side time window comparison with automatic bisection
• ▸Per-chart Y-axis pin to stabilize ranges across comparisons
• ▸CSV export at both summary and packet level
