Support for HS36B-1

[mploetner]

Hey do you think it would be possible to support the HS36B-1 controller? How can I help here?

[iMicknl]

Can you share more information on the controller? Pictures from the outside and inside of your desk controller.

Feel free to join our Discord as well to chat with like-minded people. Invite link can be found in the README.

I have the same controller and have taken pictures of the controller itself and the driver box, which is a CB38M2L.

I am happy to do testing. It seems that the ethernet cord follows the colors in the connector to the controller itself. Let me know if anything else could be of help. I would be happy to do some testing.

HS36B-1 Pin-out

The PCB is different but the pin-out is the same as the HS13B-1

RJ45 pin	Name	Original Cable Color
1	RESET	Brown
2	SWIM	White
3	EMPTY	Purple
4	PIN 20	Red
5	RX	Green
6	TX	Black
7	GND	Blue
8	+5V (VDD)	Yellow

@NotClear, thank you for letting me know. I will check this out and confirm that it works and then hopefully file a PR.

This is my adapter, which I quickly built for testing purposes.

Below is the configuration I tested for the FlexiSpot E2Q with the CB38M2L(IB)-1 controller box and the HS36B-1 control panel:

substitutions:
  upper_devicename: Flexispot E2Q
  devicename: office-desk-flexispot-e2q
  min_height: "73"
  max_height: "123"
  tx_pin: GPIO16
  rx_pin: GPIO12
  screen_pin: GPIO14

I can confirm that this works, and that the E5Q, using the the above controllers, is supported!!

Thanks @iMicknl and @NotClear. @mploetner: you can follow the instructions for the HS13B-1 as suggested above!
