I am the recent (and very excited) owner of a RPi. The project I am working on is a Home Monitor and Control system.
Untill now I have played a little bit with the RPi, GPIOs (cobbler and breadboad) and I succeeded in creating a web application that I can use to turn on or off a LED on the breadboad
I know it might sound simple to some of you but it's a real accomplishment to me.
The next step I would like to do is to control a home light switch with the RPi. After some research I have found that I could replace the "classic" wall switch with a relay that can be controller with the PI but I would still like to be able to turn the lights on or off using the wall switch also. What I was thinking is to replace the wall switch with a "button like" switch that will turn the relay on or off.
Could you please help me/point me in the right direction to find out how could I turn on/off a relay using a button, without the use of the PI ports? (the relay and button will not be phisically connected to the PI, I will use a RF 433 Mhz kit).
For now, I could really use to know if/how a relay can be turned off/on by a button.
This is the relay I intend to use : http://www.seeedstudio.com/depot/grove- ... th=156_160
Thank you very much! Any help/information is highly appreciated.
