Ok, I've figured it out
Temperature in C is hidden here:
0101 10100001 1010000
1 00101001 00010011 (29.7C, 297 = bin 100101001)
Still gotta figure out what the rest of bits are...
It would be great if I could encode signal from my moteino temperature sensors and send them to this wall clock. But is probably impossible to find out how that checksum is calculated
Anyone knows how is this encoding called (low signals of different lenght, separated with high signal)?
edit:
And this is
temperature 24.6 (11110110), transmitted on different
channels:
01011010 101011
00 00001111 01100000 1110 (channel 1)
01011010 101011
01 00001111 01100000 1110 (channel 2)
01011010 101011
10 00001111 01100000 1110 (channel 3)
I still have no idea what the other bits are... probably crc and battery level (there is low battery indicator on the clock)
