Home Automation over Online Server using NodeMCU is an IoT project to control our home appliances like light, fan, cooler, etc. from a website. In this project, we use NodeMCU and Relay Module.
We also develop a PHP website to command the NodeMCU for controlling our home appliances. We use a hosting server to online our website for controlling our home appliances from everywhere.
How it works
Setup the Website
First, we have to make a website and host it from an online server. We have developed a basic PHP website with an MYSQL database.
You have to perform following steps:
- Download the following PHP codes files which is in zip format.
- Now go to your PHPMyAdmin in your CPanel and create a database. Here we named our database as “autodb“.
- Now upload the PHP Scripting file to public_html in your CPanel’s File Manager.
- Extract the zip file and edit the connection.php file.
- Now change the “DB USERNAME“, “DB USERPASS”, and “DATABASE NAME” in the connection.php file.
- Now download the below SQL database file. Extract the Zip File.
- Import the SQL file to the “autodb” database in your PHPMyAdmin.
- Now browse the desired file location on the website in the web browser. For example – www.domain.com/automation. Here automation is the folder where we have saved our PHP files.
- The login credentials are Email: firstname.lastname@example.org and Password: 12345.
