After month of work and many times to debug, I’m proud to share with you my diy home automation box made with pcduino+arduino. I can now switch on/off lights in living, switch on/off and select color of my hacked oil diffuser, get temperature+humidity from arduino node by using rf transmissting 433Mhz nodes, basic handle of alarm system etc…

I’m using LED connected to pcduino to show rx/tx data transmission, TX 433 is connected directly to pcduino too(I’m using c_environnement provided by pcduino team to handle rcswitch and manchester library.

Arduino nano is connected to pcduino gpio pins to free one usb port(I want to add webcam support in future, so i need one usb free port)

My nodes are simple arduino pro mini(5v and 3v3 for special case, powered by samsung lion batteries!) they handle some sensors like DHT22, brightness sensors etc.. and send data every 15minutes, to preverse battery they’re in sleep all other times(they use only 22ua! in sleeping mode!)

For interfacing all these hardware I’m using openhab(http://openhab.org) and booting without X, only text mode for maintenance. Whe I need to update openhab configuration, I use ssh from another computer.

I hope to see your personnal home automation system
