ESP32

Hi ,

I like your project, have you managed to get it working on an ESP32.

Kind Regards,
Greg

Will need to take traces of button presses.

Theory:
At 'button press' read, 7 patterns are clocked through.
If a button is pressed, then the data line is pulled LOW during a latch HIGH.
For X 'button reads' this must repeat, for spa controller to recognise it as a press and not environmental glitch.

L: _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ |¯| _

Reality:
No response from SPA.

Possible reasons:

• Not pulling low hard enough to be read. I'm setting the DATA port as output and setting LOW.
  Its low impedance, but not happening, probably can't sink enough current! Try transistor/MOSFET?
• Bad timing.
• Wrong assumptions.

Could you please give me more information about, how to connect. which pin do you use.
Could you please give me an example of the mqtt message you send?
