Smart Home Automation System

Smart Home Automation System (SHAS) is an innovative project designed to provide homeowners with convenient remote control over sensors and devices in their homes. It utilizes a diverse range of channels and devices to deliver flexible and efficient control capabilities.

Although currently showcased on a breadboard for demonstration purposes, with minimal modifications or even in its current state, SHAS has the potential to be effectively implemented in real-world scenarios.

Project Features

• Control through four potential channels: physical button, Email, serial, and any device with a web browser, with smartphones being the most convenient option.
• Cloud data backups and analytics for temperature, luminosity, and intruder detection, facilitated by the ThingSpeak analytics platform.
• Real-time control, responses, and access to historical data.
• Five operational modes:

            -AC Mode: Controls the operation of the air conditioning system.

            -Light Auto Mode: Automatically adjusts the lighting based on ambient conditions or programmed settings.

            -Home Secure Mode: Enhances home security by activating various monitoring and alert systems.

            -Emergency Mode: Activates predefined emergency protocols to ensure safety and provide immediate assistance in critical situations.

• Features a simple and intuitive command syntax using "SET/GET" commands.

Operation

Setup:

• Configure the AP settings of the devices
• Connect the devices to a power supply (5VDC)
• Optional: Configure dynamic DNS on a router to enable control of SHAS from outside the home network

Usage:

After booting,

• If the device is not connected to the configured WiFi AP (home router)

            -it can only be controlled physically

• If the device is connected to the configured WiFi AP (home router):

            -It can be controlled physically

            -It can be controlled through a web UI

• If the device is connected to the configured WiFi AP (home router) and a computer:

            -It can be controlled physically

            -It can be controlled through a web UI

             -It can be controlled through the serial channel

• If the device is connected to the configured WiFi AP (home router) and a computer running the extension script with internet access:

             -It can be controlled physically

             -It can be controlled through a web UI

             -It can be controlled through the serial channel

             -It can be controlled via email
