Changelog

All notable changes to NetWatch will be documented in this file.

The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

[1.3.5] - 2025-12-04

Added

  • Gateway Ping for Internet Tab - Internet speedtests now measure and display gateway ping alongside jitter in the "Jitter & Bufferbloat" chart
  • Database Migration - Automatic column addition for gateway_ping_ms in existing databases

Fixed

  • Gateway Ping Data Collection - Fixed gateway ping not being collected during Internet speedtests (was only collected for Homenet)
  • API Response - Added gateway_ping_ms to Internet measurements API response
  • Measurement Persistence - Fixed gateway_ping_ms not being saved to database for Internet measurements
  • F5 Refresh - Fixed browser refresh briefly showing Internet tab when on Homenet tab (view persistence now applied before data loading)

Changed

  • Cache Version - Updated to v=40 for browser cache busting

[1.3.4] - 2025-01-23

Changed

  • Installation Script - Simplified install-linux.sh to only install Python dependencies (removed automated service setup)
  • Internet Tab Charts - Simplified Jitter & Bufferbloat chart to show only Gateway Ping and Jitter (removed Idle/Download/Upload Ping for clarity)
  • Homenet Tab Charts - Consolidated duplicate charts into single comprehensive "Ping Analysis" chart showing all 5 metrics: Idle Ping, Download Ping, Upload Ping, Gateway Ping, and Jitter
  • README - Updated installation documentation with manual and script-based options, improved systemd service examples

Fixed

  • JavaScript Error - Fixed undefined 'ping' variable error in Internet tab (changed to 'pingIdle')
  • Chart Consolidation - Removed duplicate Homenet Latency chart, keeping only the comprehensive Ping Analysis chart

Added

  • Chart Enhancement - Added Gateway Ping to Internet tab Jitter & Bufferbloat chart
  • Chart Enhancement - Added Jitter to Homenet Ping Analysis chart (now shows all 5 metrics in one view)

[1.3.3] - 2025-01-23

Changed

  • Installation Simplification - Removed automated installer.py (binary installation works directly)
  • Service Template - Simplified netwatch.service to user-configurable template with placeholders
  • Metric Naming Unification - Split "Loaded Ping" into separate "Download Ping" and "Upload Ping" metrics across both tabs for consistency
  • Chart Titles - Renamed "LAN Latency History" to "Jitter & Bufferbloat" and "Bufferbloat (Latency Under Load)" to "Ping Analysis" on Homenet tab
  • Internet Tab Charts - Enhanced Jitter & Bufferbloat chart to show Idle/Download/Upload Ping + Jitter (4 datasets) matching Homenet layout

Added

  • Documentation - Added Python symlink command in README for Linux systems with only python3 installed (sudo ln -s /usr/bin/python3 /usr/bin/python)
  • Manual Installation Guide - Added step-by-step manual installation instructions for Linux and Windows
  • Chart Data - Homenet Latency chart now shows 4 datasets: Idle Ping, Download Ping, Upload Ping, and Jitter
  • Chart Data - Homenet Bufferbloat chart now shows 4 datasets: Idle Ping, Download Ping, Upload Ping, and Gateway Ping

Removed

  • installer.py - Removed automated installation wizard (no longer needed)

[1.3.2] - 2025-12-04

Fixed

  • Internet Metrics Display - Reverted v1.3.1 JavaScript changes that caused all metrics to stop displaying on both Internet and Homenet tabs
  • Delta Calculations - Added missing download_latency and upload_latency fields to delta calculation function
  • Cache Busting - Updated JavaScript version to v=34 to ensure browsers load the fixed code

[1.3.1] - 2025-12-04

Fixed

  • Gateway Ping & Local Latency Display - Fixed data mapping issue where Gateway Ping and Local Latency metrics were not displaying in the Homenet tab even when data was available
  • Device Charts Not Showing Devices - Fixed issue where LAN/WiFi device charts showed "No devices found" when devices had "unknown" connection type (now included in WiFi/Wireless chart)
  • Loaded Ping Mapping - Added proper mapping for loaded ping (ping under load) metric display

[1.3.0] - 2025-12-03

Added - Homenet Feature 🏠

This release introduces Homenet - a comprehensive internal network monitoring system for testing LAN/WiFi device speeds.

New Features

  • Internal Network Speedtest Server - Built-in Python-based speedtest server (port 5201) for LAN testing without external dependencies
  • Device Scanner - Automatic discovery of network devices using ARP cache and ping sweep
  • Device Management - Track, name, and organize discovered network devices
  • LAN/WiFi Device Charts - Visualize speed performance by connection type
  • Bufferbloat Analysis - New chart showing Idle Ping vs Loaded Ping vs Gateway Ping
  • Auto-Device Registration - Devices running speedtests are automatically registered
  • Device Details Modal - View detailed measurements and history per device
  • Gateway Ping Monitoring - Measure latency to your router/gateway
  • Local Latency Testing - Test internal network responsiveness

UI Improvements

  • Tab-based Navigation - Switch between "Internet" and "Homenet" views
  • Server Status Indicator - Real-time display of internal speedtest server status
  • Auto-start Server - Server starts automatically on app launch
  • Device Cards - Visual representation of LAN and WiFi devices with last test results
  • Live Test Progress - Real-time waveform chart during speedtest execution
  • Idle/Loaded Ping Columns - Device measurements table now shows both ping types

Technical Improvements

  • Continuous Ping Measurement - Measures ping throughout speedtest to capture true loaded latency
  • is_local Device Flag - Identify the device running NetWatch
  • SSE Streaming - Server-Sent Events for real-time speedtest progress updates
  • Separate Internal Database - internal_metrics.db for homenet measurements

Changed
