At the moment I control my central heating, security and lighting.
By sending commands from my home computer.
My homeeasy central heating controller hack.
I am also able to login remotely from the internet to control the equipment at home connected to this controller.
This project is built around an Arduino board.
The arduino board is a hardware interface allowing you to control and monitor hardware devices with your computer.
And the homeeasy home automation controllers available from B&Q.
These are basically plug-in module which allows you to switch devices on and off using a remote control.
The idea behind this project was. I wanted to be able to login to my home computer and send commands that would allow me to turn lights on remotely.
Or have the computer do it automatically at a set time or when it gets dark.
Step 1: Parts needed
1 homeeasy controller - part number HE300
1 prototype board - Vero board
10 resistors - 47 ohm
4 opto isolators - RS part 308-613
Some ribbon cable.
a strip of pins to connect to the headers on the arduino board.
1 box - to put it all in.
some HE302S - remote control socket
Step 2: Basic principle
Basically the arduino board when programmed will switch the digital outputs high.
Which will send 5 volts through the resistor and light the led's.
Which will activate the opto isolator which will connect the contacts on the remote control.
which will send the comand to the remote control sockets
And turn on or off the lights, heating or anything you want.
this circuit shown is for the first on and off switches.
just repeat the circuit for the following channels
I programed the software so when I pressed (H) in the terminal the arduino board will send a 1 second pulse to my remote control and switch my heating on.
when I press(h) the board will send a 1 second pulse my heating switches off.
(S) for security on
(s) for security off
(G) garden lights on
(g) garden lights off
and so on this can be changed to any button you want
