This document outlines a smart home project to control home appliances via the internet using an ESP8266 WiFi module and relays. The objectives are to establish an internet connection between the appliances and allow control from anywhere in the world using apps on a mobile device. The process involves hardware with a WiFi-controlled relay, coding an Adafruit MQTT client, and using IFTTT to merge Google Assistant commands with the MQTT server to remotely control appliances via voice instructions.

2.  Today technology has become an integrated
part of people’s lives . It has influenced many
aspects of daily lives & allowed better social
interactions ,ease of transportation etc
 Our main objective of this project is to build a
smart home device which can be used to
control the home appliances via internet.
 It establishes the internet connection with
home appliances to be access from anywhere in
the world.

4.  control at your fingertips:- By installing
appliances in your house, such as a smart oven,
you can now use apps on your mobile device to
enjoy complete control of your home's
functions from anywhere in the world.
 Accessibility :- if there is anyone disabled
person they can easily have a access to these
appliances easily.

8.  ESP8266:-
 Low-power, highly-integrated Wi-Fi solution
 A minimum of 7 external components
 Wide temperature range: -40°C to +125°C

9.  RELAY:- A relay is classified into many types,
a standard and generally used relay is made up
of electromagnets which in general used as a
switch. Dictionary says that relay means the
act of passing something from one thing to
another.

10. Process
 This process consists of three parts:-
 Hardware (WiFi controlled Relay)
 Coding (Adafruit MQTT Client Code)
 IFTTT ( Merging Google Assistant and Adafruit
MQTT)

11.  For the hardware we need to have a relay to
switch AC appliances which is operated
through wifi.

12. 2-coding
 For coding the ESP8266 we are going to
use Adafruit MQTT Library which you
can download it from my GitHub
account. In that library, we are just going
to modify the example code called
“mqtt_esp8266”.

13.  IFTTT stands for If This Then That which
basically provides a platform on which we can
merge two different services. Like for our
project, we are going to use Google assistant
and Adafruit MQTT.
 So any instruction coming from Google
assistant will be processed by IFTTT and
accordingly the actions will be performed on
Adafruit MQTT server side.
