Story

IOT SMART OUTLET

A smart iot outlet controlled by Google assistant, telegram, button widget, blynk app etc. An easy way to automate your home

This project can be divided into 3 parts

1 Controlling a light through blynk app

2 Connecting blynk with ifttt

3 Making the extension code

Controlling light through blynk

Step 1 - Install blynk app from play store

Step 2-Click on new project

Give it a name, select nodemcu as your board and connection type as wifi

After that click on create, a dialog box like this will appear

Click ok, this token is needed later on this project

Step 3-Click on the add button

Step4- Add 3 buttons

Step 5-Give the button a name, chose whether it is push or switch like button and set the digital pins

Selct the pin D1 for switch 1,D2 for switch 2,D3 for switch 3 respectively

So the blynk app settings are completed

Step 5-uploading the code into nodemcu

By watching this video, we can Learn how to programme nodemcu using arduino ide

Connecting blynk with ifttt

Step 1-Download and login into ifttt

Step 2-Click on my applets

Step 3-click + button to create new applet

step 5- Click on "this" button

Step 5-Search for Google assistant and select it

Step 6 -Select "Say a simple phrase option"

Step 7-Fill in the blanks ,with what i exactly filled up,its your choice

after that click on create a tigger button

A new window like this will open

Click on that button

Search for webhooks and select it

A window like this will open up,select make a web request

In URL enter http://cloud.blynk.cc:8080/XXXX your TOKEN XXXX/update/zzz
For indian users replace cloud.blynk.cc:8080 with this ip address 188.166.206.43
and replace XXXX your TOKEN XXXX with your actual token and ZZZ with the PIN number , for Digital PIN use DX like D1, D5 etc. and for Virtual PIN use VX like V1 ,V5 etc.
in Method select PUT to WRITE a value to that PIN.
in Content Type select application-json.
in body write ["0] to make the PIN High or ["1"] to set the PIN Low

click on create action button

click on finish button ,now the applet creation process is completed

Now make a applet for turning off light by following the exactly same steps mentione above ,but make the necessary changes as given below

Replace turn on liight with turn off light

Replace ["0"] with ["1"]

Now applet for switching off the light is completed

Now the software part is completed lets move onto the hardware part

 *************************************************************
  This example runs directly on NodeMCU.

  Note: This requires ESP8266 support package:
    https://github.com/esp8266/Arduino

  Please be sure to select the right NodeMCU module
  in the Tools -> Board menu!

  For advanced settings please follow ESP examples :
   - ESP8266_Standalone_Manual_IP.ino
   - ESP8266_Standalone_SmartConfig.ino
   - ESP8266_Standalone_SSL.ino

  Change WiFi ssid, pass, and Blynk auth token to run :)
  Feel free to apply it to any other example. It's simple!
