//## Plugin-44 Auriol V3 ##
//#######################################################################################################
/*********************************************************************************************\
* This plugin takes care of decoding the Auriol protocol for sensor type Z32171A
*
* Author : StuntTeam
* Support : http://sourceforge.net/projects/rflink/
* License : This code is free for use in any open source project when this header is included.
* Usage of any parts of this code in a commercial application is prohibited!
*********************************************************************************************
* Changelog: v1.0 initial release
*********************************************************************************************
* Technical Information:
* Decodes signals from a Auriol Weatherstation outdoor unit, (40 bits, 433 MHz).
*
* Auriol Message Format:
* 1011 1111 1001 1010 0110 0001 1011 0100 1001 0001
* B F 9 A 6 1 B 4 9 1
* AAAA AAAA BBBB CCDD EEEE EEEE EEEE FFFF FFFF GGHH
*
* A = ID?
* B = Rolling code?
* C = possibly battery indicator ?
* D = trend (2 bits) indicating temp equal/up/down ?
* E = Temperature => 0x61b (0x61b-0x4c4)=0x157 *5)=0x6b3 /9)=0xBE => 0xBE = 190 decimal!
* F = humidity: 49%
* G = ?
* H = channel: 1 (2 bits)
*
* Sample:
* 20;C2;DEBUG;Pulses=82;Pulses(uSec)=475,3850,450,1700,450,3825,450,3900,450,3725,450,3825,450,3825,450,3900,450,3725,450,1700,450,1700,450,3900,450,3725,450,1700,450,1700,450,1800,450,1625,450,3800,450,3825,450,1800,450,1625,450,1700,450,1700,450,1800,450,3725,450,3800,450,1700,450,1800,450,1625,450,3825,450,1700,450,3900,450,1625,450,1700,450,1700,450,3900,450,1625,450,1700,450,1700,450,3825,500;
