Focus Tracker Embedded System

This repository contains a multi-device focus and pomodoro system built around MQTT.

• Focus_Tracker: PC service that detects presence, runs the pomodoro engine, and publishes state.
• Remote_control: ESP32-S3 remote controller with button and web UI to send commands.
• Logger: ESP32-S3 actuator and status dashboard that renders focus state and attention on LEDs.

Architecture

• The PC service publishes presence, focus state, and light mode over MQTT.
• The remote controller publishes commands and shows current state on a NeoPixel.
• The logger subscribes to state and presence topics, drives LEDs, and exposes a web dashboard.

Quick Start

1. Update broker and WiFi settings in:
   • Focus_Tracker/config.py
   • Remote_control/include/app_config.h
   • Logger/src/app_config.cpp
2. Build and upload ESP32 projects with PlatformIO (Logger and Remote_control).
3. Run the PC service from Focus_Tracker/main.py (see Focus_Tracker/README.md).
