Adding X10-Security protocol

[wherzig]

Hi,

rtl_433 is really great. This evening I was able to add reception of the X10 security protocol to rtl_433. I was able to receive a DS10A sensor with this (changed at 433 Mhz). It should also work with sensors for the Marmitec safeguard alarm system at 433 Mhz. See http://www.marmitek.com/de/produkt-details/home-automation-security/x-10-security/safeguard.php. I have this also at home.

It just took a few hours today. Your hints for short_limit, long_limit and reset_limit are really good. I did not think that I would be so easy!

You may add the following code to rtl_433 for this to rtl_433.c if you want to.
I am looking forward to add other protocols. Unfortunately I did only take a X10 DS10A security sensor to the hotel at vacations....

Have fun!

Regards

Willi

r_device x10sec = {
.id = 6,
.name = "X10-Security",
.modulation = OOK_PWM_D,
.short_limit = 1100,
.long_limit = 2200,
.reset_limit = 10000,
.json_callback = &x10sec_callback,
};

// add this to the init protocol section
register_protocol(demod, &x10sec);

Clone on github and send a pull request and I will merge it.

Hmm. I am new to github.
Normally I use sourceforge.net with SVN.

You mean that I should clone your repository and do a fork? And then do the pull request? This is what I have found about it: https://help.github.com/articles/using-pull-requests

Right?
