*
* Globaltronics GT-WT-03 sensor on 433.92MHz.
* The 01-set sensor has 60 ms packet gap with 10 repeats.
* The 02-set sensor has no packet gap with 23 repeats.
* Example:
* {41} 17 cf be fa 6a 80 [ S1 C1 26,1 C 78.9 F 48% Bat-Good Manual-Yes ]
* {41} 17 cf be fa 6a 80 [ S1 C1 26,1 C 78.9 F 48% Bat-Good Manual-Yes Batt-Changed ]
* {41} 17 cf fe fa ea 80 [ S1 C1 26,1 C 78.9 F 48% Bat-Good Manual-No Batt-Changed ]
* {41} 01 cf 6f 11 b2 80 [ S2 C2 23,8 C 74.8 F 48% Bat-LOW Manual-No ]
* {41} 01 c8 d0 2b 76 80 [ S2 C3 -4,4 C 24.1 F 55% Bat-Good Manual-No Batt-Changed ]
* Format string:
* ID:8h HUM:8d B:b M:b C:2d TEMP:12d CHK:8h 1x
* Data layout:
* TYP IIIIIIII HHHHHHHH BMCCTTTT TTTTTTTT XXXXXXXX
* - I: Random Device Code: changes with battery reset
* - H: Humidity: 8 Bit 00-99, Display LL=10%, Display HH=110% (Range 20-95%)
* - B: Battery: 0=OK 1=LOW
* - M: Manual Send Button Pressed: 0=not pressed, 1=pressed
* - C: Channel: 00=CH1, 01=CH2, 10=CH3
* - T: Temperature: 12 Bit 2's complement, scaled by 10, range-50.0 C (-50.1 shown as Lo) to +70.0 C (+70.1 C is shown as Hi)
* - X: Checksum, xor shifting key per byte
* Humidity:
* - the working range is 20-95 %
* - if "LL" in display view it sends 10 %
* - if "HH" in display view it sends 110%
* Checksum:
* Per byte xor the key for each 1-bit, shift per bit. Key list per bit, starting at MSB:
* - 0x00 [07]
* - 0x80 [06]
* - 0x40 [05]
* - 0x20 [04]
* - 0x10 [03]
* - 0x88 [02]
* - 0xc4 [01]
* - 0x62 [00]
* Note: this can also be seen as lower byte of a Galois/Fibonacci LFSR-16, gen 0x00, init 0x3100 (or 0x62 if reversed) resetting at every byte.
* Battery voltages:
* - U=<2,65V +- ~5% Battery indicator
* - U=>2.10C +- 5% plausible readings
* - U=2,00V +- ~5% Temperature offset -5°C Humidity offset unknown
* - U=<1,95V +- ~5% does not initialize anymore
* - U=1,90V +- 5% temperature offset -15°C
* - U=1,80V +- 5% Display is showing refresh pattern
* - U=1.75V +- ~5% TX causes cut out

* - data0 (0-bits) have then a '0' pulse length of ca. 2000us
* - data1 (1-bits) have then a '0' pulse length of ca. 4000us
* - syncPost after dataPtr has a '0' pulse length of ca. 16000us
* This analysis is the reason for the new r_device definitions below.
