Using Raspberry Pi To Create Home Automation! and access from anywhere online!

The basics!

First you will need
1 x raspberry pi (model b)
1 x 2 module relay switch board for aduino or raspberry pi (1 minimum) 5v look on ebay!
1 x 8 gb sd / micro sd card (8gb minimum)
1 x power source for rpi
4 x wires for gpio pins (4 wire minimum) found on ebay
1 x weakened to get to grips with experimenting with this project!

I recommend looking on google and youtube and searching as much as you can with raspberry pi or aduino or if you want to just buy 1 of these from me see my information below!

Download raspbian (linux) os.

To allow the user to control the gpio pins using python software accessible with also php and javascript languages you may need to install this gpio library (see below).

To install gpio library for python and raspberry pi

Code:

sudo apt-get update
sudo apt-get -y install python-rpi.gpio


Code:

For other methods and resources google search or visit the link below

On my own I am using JavaScript, python, css, php, database, ftp, ssh, phpmyadmin , webserver and pages to remotely access this automation system from potentially anywhere!
I also set my rpi to auto login, and have a static ip on my local home network, then use port forwarding to set a remote access port, I use php security scripts to protect and secure pages that can change switch states, I use database to store each switch change and other useful tracking information like ip etc,

Also I have ftp so i can remotely update this stup, ssh so i can connect securely to this setup!
crontabs (cronjobs) so that i can automate the whole system.

Creating php functions



Creating a php function (after gpio library is installed)

Code:

exec("gpio -g mode 4 out");

$state = $_GET["total"];

Code:

if ($state == "on"){

   exec("gpio -g write 4 1")

sleep(1);

  exec("gpio -g write 4 1")

}

As you can see you can make the above examples into a specific function

Code:

function Switch01Toggle {
if ($state == "on"){
exec("gpio -g write 4 1")
} else {
exec("gpio -g write 4 0")
}

Code:

1 = on and 0 = off

There are different or better ways to do all this and if you wish feel free to share your methods or links to them here!

I have wrote 3 projects 1 for 2 module switch, and 1 project for 8 module switch! and also 10 switch module.

Please let me know if you want a custom built raspberry pi already setup and ready to go! i will provide 2 switch automation for £60 and 8 switch for £100, also 10 switch for £150. get in touch with me for more details!


You will have a custom made secure remote accessible for use with upto 10 amp per 1 module in either ac or dc current, you could even combine these to get higher amps for example 2 x 10 amps is 20 amps.

you could even switch data with this to redirect or cut of telephone or network routes!


It will be fully working with its own ip will have 8 gb (at least)
Will be accessible though http, ftp, ssh with a password (you can edit or ask for specific password to be used).
