/*
|
||||
* X10 Security sensor decoding for rtl_433
|
||||
*
|
||||
* Based on code provided by Willi 'wherzig' in issue #30 (2014-04-21)
|
||||
* https://github.com/merbanan/rtl_433/issues/30
|
||||
* Danke, Willi
|
||||
*
|
||||
* Tested with American sensors operating at 310 MHz
|
||||
* e.g., rtl_433 -f 310.558M
|
||||
*
|
||||
* This is pretty rudimentary, and I bet the byte value decoding, based
|
||||
* on limited observations, doesn't take into account bits that might
|
||||
* be set to indicate something like a low battery condition.
