Dooya RF Remote possible off-by-one

pedrovanzella commented 3 months ago

The problem

When receiving an RF Remote with the Dooya protocol, ESPHome detects it with ID 0x00b2c5a9. However, both a Flipper Zero and a HackRF Portapack with the Mayhem firmware read the same remote as ID 0x004d3a56. If you add 0x00b2c5a9 and 0x004d3a56, you get 0x00ffffff, so this is probably an off-by-one error somewhere.

The Button, Check and Channel codes also look weird. Channel 0 reads as 127, and channel 1 as 126, and so on. Button Up, short press reads as Code 14, check 1, and long press as Code 14 check 14.

If I try to send the decoded content back through an RF Transmitter with the Dooya protocol and all the same data (ID, Channel, Button, Check etc), my blinds don't respond, and I'm not able to decode the signal in the Flipper or the HackRF, even though I do see some signal being output, indicating the transmitter is indeed trying to send something.

If I plug in the data from the Flipper dump, I'm not able to get the blinds to respond either. Note that I can control the blinds from the Flipper or the HackRF with those dumps.

I have the same problem, sending the same decoded content back with the Dooya protocol does not work as expected.

Same problem here - sending captured values does not work.

It is not off by one, the 1s and 0s are flipped completely.

>>> correct = 0x004d3a56
>>> bin(correct)
'0b010011010011101001010110'
>>> wrong = 0x00b2c5a9
>>> bin(wrong)
'0b101100101100010110101001'

No - does not work. It works if I send the captured RAW data, but does not work if I try to re-send the (new/changed) Dooya data. Old Dooya data was: [I][remote.dooya:116]: Received Dooya: id=0x00BAF9E5, channel=174, button=10, check=10 New Dooya data is: [I][remote.dooya:116]: Received Dooya: id=0x0045061A, channel=81, button=5, check=5 RAW-Data I send is: code: [4759, -1556, 306, -764, 670, -402, 304, -764, 306, -765, 306, -763, 671, -403, 303, -764, 671, -405, 307, -760, 310, -760, 310, -762, 308, -763, 307, -759, 676, -397, 674, -397, 309, -763, 313, -758, 312, -758, 312, -760, 675, -393, 677, -395, 312, -753, 682, -392, 314, -760, 316, -754, 680, -391, 316, -754, 681, -389, 317, -755, 315, -754, 317, -751, 682, -394, 319, -754, 681, -390, 316, -753, 682, -390, 317, -749, 685, -387, 319, -750, 685, -404]

@deejaybeam what do you receive when you transmit? Maybe come to the esphome discord where it's easier to interactively discuss it.
