X10 server

I would like to control my X10 stuff (3 devices) from a web browser.
The ethernet part
This is my first essay to use the mbed with ethernet.
It is straight forward, compared to a PIC24F + ENC2860 + magicjack...
The main idea is to get rid of hardware connexion problems (the magicjack). So, in a first try, use an RJ45 cable that you cut : http://mbed.org/forum/mbed/topic/1239/?page=1#comment-13519
I found the information of the norm T568A on : http://upload.wikimedia.org/wikipedia/commons/thumb/c/c4/Wire_white_green_stripe.svg/60px-Wire_white_green_stripe.svg.png
It looks like :
I tried with the excellent httpclient to send some data to a server of mine, it works !
Then the server is implemented using httpserver : unfortunately, the example http://mbed.org/cookbook/HTTP-Server?action=view&revision=244 has a missing .htm file, but I found one on : http://mbed.org/users/jnesystech/notebook/ch4_6/
This implement a simple web page, to be but on the root of the mbed, that has a toogles button which power the LED2 of the mbed.
Then The 3 Led, in perspective to 3 X10 devices

if (tm.read()>.5) {

see also how to add RPCFunction :
The X10 part
Pay attention that this is RF X10 signals that we will send thanks to a 315 MHz transmitter :
The V0.21 is a working one
Import programWeatherRx
Web Server and send X10 RF orders to X10 RF transceivers Switch On/Off Appliance No weather Rx at the moment...

The page gives the following output :
As always with mbed systems, there are few electronic parts added :

Have you tried the dim function? and what range do you get?
Also which X10 wireless module are you using for a receiver? Are all of them working at 315Mhz?
receiver is TM751 module but it work with any X10 RF receiver Mine are US ones so the freq is 315 MHz European ones are 433 MHz Have a look at ido bartana website : http://www.idobartana.com/hakb/index.htm and my site : http://www.baghli.com/dspic_x10rf.php
I didn't programmed the dim function but I am quite sure it will work. The range depends on your emitter... I have about 10 m range with a wrapping wire used as antenna ;-)

Have you tried to receive the wireless signals from the X10 motion sensors? Spakrfun has a 315Mhz receive module that looks like it might work - assuming that is also 315Mhz.
Non I don't have a motion sensor, but I have unused 315 MHz receivers, I will try to receive humidity and temperature sensor (those you found in meteo stations). I am busy at the moment and will try this in some weeks inchaAllah. Best regards

Hi Lotfi Baghli. I know nothing about java language, but I can see in the program by clicking on each button it send a RPC request to mbed. It would be possible to make from the variation of some variable in the program on the mbed (for example the value of an analog input) the mbed update and display this value on the website?. regards
It is simple, just follow the samples, but it is in C language Regards
Please log in to post comments.
Lotfi, What is this 318MHz transmitter you are refering to?
Regards, ...kevin
