It has been a while since I last posted but that is not to say that I am not doing anything.
For a while now I have had a Raspberry Pi and it was something that when it was released caused a bit of storm. A low cost circuit board that had the ability to be programmed (used very loosely here) anyway you wish.
So knowing what this little piece of kit was capable of it was then time to add some bits to it to so I could build........... a DIY Home Automation system. I am going to control one table lamp device wirelessly with a basic web interface.
Nothing too intensive
For this kit I bought:
1. Raspberry Pi - There are additional items like SD Card, USB cables, mouse and keyboard to get setup but I won't be covering that in too much detail.
2. Tellstick - A USB transmitter that broadcasts at 433Mhz
3. 3 Home Easy plug switches HE302
4. 2 Gang wall switch with dimmer HE108
First of all get your up to date Wheezy linux distrobution. I won't go into detail on this as it is well documented.
Once you are up and running you need to install four items.
Personally I followed this order.
1. Lightppd server - web interface hosting on your own server
2. PHP5 - server side scripting
3. Mysql - Database storage for events (note to self hurry up and do the temperature sensor article)
Install 1, 2 and 3 by following the instructions here http://www.penguintutor.com/linux/light-webserver this is by far the most easy instructions I have found to date and caused no problems at all.
Next install the software on the Pi for the tellstick by following the instructions here http://elinux.org/R-Pi_Tellstick_core
Once you are done there all you need to do is drop the following code into a file called "index.php"
<?php
include 'temp.php';
?>

If you need guidance on the set up of the tell stick and pairing my video 'How to pair Home Easy Plug to Raspberry Pi with Tell stick' will give you the relevant code but for more comprehensive understanding please visit http://developer.telldus.com/wiki/TellStick_conf as this will give you all the information you need.
You will notice that there is an element of the webpage that is geared up for getting temperature readings. All you need to do create a file called temp.php in your 'www' folder and add the following code.
<?php
//File to read
$file = '/sys/bus/w1/devices/28-000003dcfad1/w1_slave';
//Read the file line by line
$lines = file($file);
//Get the temp from second line
$temp = explode('=', $lines[1]);
//Setup some nice formatting (i.e. 21,3)
$temp = number_format($temp[1] / 1000, 1, '.', '');
?>
Once you have done this you need to wire up your DS182b 1 wire temperature sensor. I have done the following two videos to help.
How to get Temperature readings from DS18b20 for the Raspberry Pi
If you follow the instructions in both videos you need do nothing else!
As a note if you put your Raspberry Pi outside of your firewall you will then be able to remotely control the plugs anywhere where you can get access to your IP address.
