Smart Home Application

A mobile-friendly app for controlling lights, switches, and sensors around the home, with automation scenes and remote access from anywhere.

Overview

Retrofitting a home with smart control usually means juggling several disconnected apps, one per brand of switch or sensor. This system replaces that with a single app: existing light switches and appliances are wired to relay modules that join the same home network and report into one dashboard.

From there, every device can be grouped by room, scheduled, or chained into automation scenes — like turning off all the lights and locking up with a single tap when leaving the house.

How It Works

Relay modules and sensors publish state and accept commands over MQTT, the backend keeps a record of every device and scene, and the app reflects changes in real time.
