Nowadays, the development of smart devices for home automation has rapid growth. The arising problem is how to integrate and control these devices efficiently to have a better safe comfort life. In IoT enabled Smart Home environment various things such as lighting, home appliances, computers, security camera etc. all are connected to the Internet and allowing user to monitor and control things regardless of time and location constraint. Each of the devices has its own configuration technique, which creates different problems of integration. The paper presents the design and implementation of an Ethernet-based Smart Home intelligent system for monitoring the electrical energy consumption based upon the real time tracking of the devices at home. The proposed system works on real time monitoring and voice control, so that the electrical devices and switches can be remotely controlled and monitored in a user friendly and a mobile way.
With the growing demand, comes the growing competition which has forced the competitors to come out with more intelligent, efficient as well as user friendly models. This has made our lives easier. The
Internet of Things will maintain our appliances it will regulate our lights, heat, AC, and other home appliances and devices, turning them on and off as we enter and exit rooms.
Save money on energy use, while keeping your office or building comfortable. The cost of simply forgetting to turn off your classroom lights and electric appliances can really add up over time. Automating your heating and lighting systems allows you to hand over the routine chores to a smart system and remove the cost of human error.
? Internet of things influences us in many ways and people are continuously developing new smart gadgets to improve lifestyle. IoT has contributed a lot towards automation of home duties. The control aspects which IoT has provided are really great for home automation like you can control everything just with the help of a single click. You can have a log of events to keep a check on who visited your house, when a family member did something like got home, left home of turned a fire alarm off. Smart home is about connecting the electric appliances in a network so that they can be remotely accessed and controlled. How to integrate multiple devices into one and transfer the information to the owner is the question of interest.
To cut the long story short IoT has enabled us to control everything virtually, without physically being present at the spot, you can keep check of every event. This is one important accomplishment in security aspect too that everything is being monitored and controlled via single platform, using security enabled communication protocols.
This paper proposes an IoT based smart and intelligent energy and security management system to autonomous power control system in a user friendly and a mobile way so that a user can manage the power management as well as security of their house even when not at the house. In proposed model an Ethernet based system that let users monitor real time switching information of the
electrical devices and controlling them through an android app as well as monitoring the security of their homes in case of unwanted entry or fire.
The app cannot work in an area where internet is not available so what if there is an emergency at home and you are in an area where internet is not available.

Home automation is a matter of concern in today’s world, people want more ease with simple to use appliances and internet of things provide us with such devices that make our everyday life easier. This paper introduces an IoT based smart and intelligent energy and security management system in a mobile way so that people can manage the power and security of their homes and reducing the power consumption and maximizing the energy utilization. Foe this purpose, the proposed model Ethernet based system control and track information of the electrical devices and controlling them through an android app.
The proposed model uses temperature sensor and smoke sensors to check for fire at the user’s home, PIR motion
sensors to check for the unwanted presence at their homes and also monitor and control the real time tracking and switching of all their electrical devices through an android based mobile app. The system is connected to this android app using internet connectivity for better and fast communication. The model has an option of controlling devices by either sending voice commands or by simple tap-to-toggle system, making the overall system user friendly and easy to manage.
So, getting in detail about the model, we have temperature sensor which works along with smoke sensor to check the
presence of fire at home, PIR motion sensor to detect the human movement in the house, and relay connected devices so that they can be easily toggled by the microcontroller. The brain of our model is an Ethernet based Intel Galileo 2nd Generation Board which let our devices and sensors connected to the internet.

On the other side of our model, we have an android based mobile app that has options to track the switching time of the devices, controlling the switching of devices either through touch mode or voice mode and also generates alerts in case of security breach or fire. The app is android based which is connected to the internet thorough either Wi-Fi or mobile dat. It connects to the Intel Galileo based server over the internet and lets the users to monitor with the help of an internal mobile timer and toggles the switching by tap-to-touch or voice using Google API speech recognition tool. User can manually switch on or off the PIR sensor or the fire tracking system and even get alerts in
case they do detect a change. The alert is sent real time to the user app and shown in the alert tab. Thus, an energy monitoring security system is being set up in the home with a user-friendly mobile app to make your home a smart and an intelligent home.
An android app is made for controlling and monitoring the features of smart home (herein MY Home) The app is based upon android open source development which has to be connected to the internet through mobile data or using a Wi-Fi.
In other options the user has an option of changing the Settings of the app, accessing the Touch Mode, accessing the Voice Mode and Viewing the status of the connected devices. This is the most user’s friendly feature of this app that let users toggle the state of devices using available voice commands. The feature uses the default Google API speech recognition tool that recognizes the available commands and sends the output according to the selected command. The user can also play the voice command and scroll over the list.

All the tracking and monitoring is based upon the date at which the system was last refreshed which can be done through settings of the app, an auto connect feature that let the app automatically connect to the internet when possible and to refresh the status of the app so that a fresh tracking and monitoring is deployed.
From experimental result, it has been clear that proposed system given has proved to be a better way of energy and security management. The main idea of this system is to monitor the energy usage and security of the house in a user friendly and a mobile way so that a user can manage the power management as well as security of their house even when not at the house itself.
