Control 9 Appliances Without Internet

Now a days, Home automation is the most popular new trend inside the house improvement market with increasingly more technological advances. Home automation way of literally run your home automatically. Home automation is part of internet of things (IOT). by using this system we can control home appliance over the android phone or computer.

In this project we are controlling 8 appliances using android phone. yes we can control up to 8 electronic appliances using your mobile phone without internet connection. you just need to make a simple project and install this android application on your mobile phone. you can control any Electronic devices like TV, Fan, AC, Water pump, Tube light, any thing that you want to controlled.
For this project we are using NODEMCU development board. ESP8266 Wifi Module, or Nodemcu or any of the other ESP8266 based boards can be used to build web server through which all the GPIO pin of the board can be controlled over WiFi.

Note : for demonstration we are controlling 8 devices.

Today, we are going to put that web server in use and control 8 home appliances with it.

• Nodemcu ESP8266 development board just 330/- Link
• 8 channel relay module just 250/- Link
• 5v mobile old charger
• Breadboard (optional) just 90/- Link
• Jumper wire just 220/- Link

Other Components

• Arduino Uno just 384/- Link
• Arduino Nano just 330/- Link

Arduino Software Link

• NodeMCU – Relay Module
• Nodemcu pin D0 --> Relay module pin IN1
• Nodemcu pin D1 --> Relay module pin IN2
• Nodemcu pin D2 --> Relay module pin IN3
• Nodemcu pin D3 --> Relay module pin IN4
• Nodemcu pin D4 --> Relay module pin IN5
• Nodemcu pin D5 --> Relay module pin IN6
• Nodemcu pin D6 --> Relay module pin IN7
• Nodemcu pin D7 --> Relay module pin IN8
• Nodemcu pin VCC --> Relay module pin VCC
• Nodemcu pin GND --> Relay module pin GND

First open Arduino IDE software, next to select the board go to Tools ==> Board ==> and search for NodeMCU 1.0(ESP-12E Module) and click on it.

If you don't have Nodemcu board installed then follow the procedure below link

Installing ESP8266 Board in Arduino IDE

To get Arduino code just mail me i will send you code.

Then, Download the source code below from the link and open code. We need to do some changes, just change your wifi ssid and wifi password.
Now , upload the source code to the nodemcu, en͏s͏u͏r͏e ͏e͏v͏e͏r͏y͏t͏h͏i͏n͏g ͏i͏s ͏c͏o͏n͏n͏e͏c͏t͏e͏d ͏a͏s ͏d͏e͏s͏c͏r͏i͏b͏e͏d ͏u͏n͏d͏e͏r ͏t͏h͏e ͏s͏c͏h͏e͏m͏a͏t͏i͏c͏s ͏s͏e͏c͏t͏i͏o͏n. ͏a͏f͏t͏e͏r ͏u͏p͏l͏o͏a͏d͏i͏n͏g ͏t͏h͏e ͏c͏o͏d͏e, ͏open serial monitor and y͏o͏u ͏s͏h͏o͏u͏l͏d ͏s͏e͏e ͏t͏h͏e ͏i͏p ͏a͏d͏d͏r͏e͏s͏s ͏o͏f ͏y͏o͏u͏r ͏w͏e͏b ͏s͏e͏r͏v͏e͏r ͏d͏i͏s͏p͏l͏a͏y͏e͏d ͏i͏n ͏t͏h͏e ͏s͏e͏r͏i͏a͏l ͏m͏o͏n͏i͏t͏o͏r ͏a͏s ͏s͏h͏o͏w͏n ͏b͏e͏l͏o͏w.

Application Link "DHome"

Now open the "DHome" android application and add this IP address. To add the IP address follow the below process. First click on setting symbol and then type this IP address and click on save button, and you are all done.
Note : In DHome android application there is 9 button, you can also connect one more device to system, means you can control up 9 electronic devices.
