This document presents a project to build a mobile application to control electric devices connected to switches for more flexible home automation. It involves using an Android app, Arduino microcontroller, GSM and DTMF modules. The app would allow sending SMS commands via DTMF tones to operate relays and devices remotely. Developments so far include prototyping the Android app, testing the SMS module, and studying Arduino and DTMF technology. The project aims to improve home security and convenience with smart automation capabilities.
