IoT-Enhanced Retrofitting Old into Smart Appliance

Welcome to our IoT project aimed at creating a sustainable and cost-effective solution for turning traditional analog appliances into smart appliances. This initiative addresses critical challenges in urban living, such as energy efficiency, parking space dependency, and environmental sustainability.

Demo and Presentation

Please kindly check our youtube video : https://youtu.be/JrmqSYBcZCY

Background

The increasing population leads to higher transportation demands, intensifying parking space dependency. While public transportation remains a sustainable option, private vehicles offer unmatched convenience. Although driverless shared cars could be a future solution, the immediate need lies in enhancing existing infrastructure. IoT-based parking systems provide a smarter and more achievable solution than traditional methods, which often result in traffic congestion and minor collisions due to difficulty in locating vacant slots.

Project Goal

Our project focuses on retrofitting traditional analog appliances with smart functionalities without replacing them entirely, reducing e-waste. This approach makes existing appliances:

Remotely Controllable

Energy Efficient through features like overcharging prevention and reduced vampire energy consumption. Vampire energy accounts for 5–10% of residential electricity use and approximately 1% of global CO2 emissions. To combat this, our solution automatically switches off appliances when fully charged.

Scope

• Retrofitting analog appliances with smart plugs.
• No development of new IoT devices or smart home systems.

Tech Stack

• Frontend: PHP, HTML
• Backend: Python
• Database: MySQL
• Mobile Connectivity: Flutter
• Hardware : Tuya Smart Plug
• IOT Connection : Tuya SDK

Documentation

Full documentation can be access on these files inside this repo : Presentation.pdf and Documentation.pdf

How to run the system?

1. PREPARING THE LIBRARY

Install all the python library required to run the system

(The libraries were listed inside app folder in requirements.txt)

pip install -r requirements.txt

2. REGISTERING DEVELOPER ACCOUNT

Follow the tutorial of the libraries to register the account to the manufacturer: https://github.com/tuya/tuya-connector-python

3. CONFIGURE TUYA DEVELOPER CREDENTIAL

Change the credential of your Tuya Protocol on the file app/Protocol_Function.py according to the credential generated from the 2nd step.

Fill these string from class Protocol_Function(), with the suitable credentials' value :

ACCESS_ID = ""
ACCESS_KEY = ""
API_ENDPOINT = ""
MQ_ENDPOINT = ""

4. SQL

Make a MYSQL server and make a new database with name : IOT_Project

And then import this file to the mysql server : IOT_Project.sql

5. CONFIGURE SQL CREDENTIAL

Change the credential of your SQL on the file app/SQL_Function.py according to the credential generated from the 2nd step.

Fill these string from class SQL_Function(), with the suitable credentials' value :

HOSTNAME = ""
USERNAME = ""
PASSWORD = ""
DATABASE = "IOT_Project"

6. WEB APPLICATION FOR REGISTERING USER, DEVICE, SCHEDULE :

Make a web server for the frontend to registering users, controlled devices, and the schedule. Follow the instruction here : https://github.com/Bamistand/IOT_Frontend_Project.git

7. SCHEDULER FOR SMART-GRID SMART APPLIANCES :

Run scheduler every minute 00, 15, 30, and 45 to run the /app/Scheduler_Function.py .

For windows : Use task scheduler

For ubuntu linux : Use cron with time setting -> */15 * * * *

8. OVER-CHARGING PREVENTION SERVER

a. Run the python application server inside an ubuntu VM :

python .\API_Protocol.py

b. Do not forget to try it

• Turn off your tuya device.
• Run this testing with postman :

Handling :

POST

URL :

http://[YOUR_SERVER_IP]:8001/changeDeviceStatus

Body Parameter :

{
    "SystemDeviceID": "[DEVICE_ID_FROM_POINT_6]",
    "CommandType": "CHANGEDEVICESTATUS",
    "CommandStatus": "True",
    "PhoneChargerReason": "TEST"
}

• Make sure it return like this :

{
    "message": "{'result': True, 'success': True, 't': ...., 'tid': .....}",
    "pushResult": true
}

• And, make sure the testing device now on

9. OVER-CHARGING PREVENTION MOBILE APPLICATION

Install the mobile application for over-charging prevention according to this : https://github.com/KorawitRupanya/BatteryCheckerFlutter

How to run with Docker?

1. Use docker build command which it will use the Dockerfile to build a new container image(protocol is the name of the image which you can specify to whatever you want)

docker build -t protocol .

2. Start your container using docker run command and specify the name of the image you just created:

docker run -dp 3000:8001 protocol

3. Now the API should run at localhost:3000. You can check by go directly to the port, if you see the massage {"message":"API Server of System is Ready"} that means the API is running and ready to be used.
