* This Plugin takes care of reception of the Select Plus wireless doorbell (Sold at Action for 6 euro's)
|
|
* PCB markings: Quhwa QH-C-CE-3V aka QH-832AC
|
|
* Also sold as "1 by One" and "Delta" wireless doorbell.

*********************************************************************************************
|
|
* Technical information:
|
|
*
|
|
* There are two known models:
|
|
* SelectPlus (200689103 - Black - Datecode:0614) also sold as "1 by One" (O00 QH-0031)
|
|
* PCB details: Quhwa, QH-C-CE-3V, 09.10.16, CPU: MC908T
|
|
* SelectPlus (200689101 - White - Datecode:0914)
|
|
* PCB details: Quhwa, QH-C-CE-3V, REV1.0, CPU: MC908T
|
|
*
|
|
* Each frame is 35 pulses long. It is composed of:
|
|
* 101011001010110010110011010 10101010
|
|
* The first block appears to be an unique ID
|
|
* The second block appears to be some kind of identifier which always is 0xAA (10101010)
|
|
* Converting the pulses into bits results in a 13 bit unique address and a 4 bit identifier:
|
|
*
|
|
* B) 1110000110011 0000 => 1C33 0 B)lack push button
|
|
* W) 1101110110100 0000 => 1BB4 0 W)hite push button
|
|
*
|
|
* Note: The transmitter sends 43 times the same packet when the bell button is pressed
|
|
* the retransmit is killed to prevent reporting the same press multiple times
|
|
*
|
