[HS01B-1] None of the commands work

[staxDB]

Hey, damn cool project and just what I was looking for!

I am having a few issues in my setup though: I have been trying ,to control a flexispot desk remotely. Unfortunately none of the scenarios work.
I first tried the ESPHome solution and used an ESP8266. Since this did not work (or my desk did not respond at all), I still tried the variant with the Raspberry Pi - Unfortunately also unsuccessful. I even tried to execute the single "Up" command alone with a Python script, but the desk does not react to it.

Which setup I have: A Flexispot E5B with an HS01B-1 control unit and a CB38M2A-1 control module. I connected the Raspberry Pi and also the ESP8266 to the control module (CB38M2A-1) via a modified Ethernet cable. For the correct ethernet cable mapping I used this table as a guideline:
https://github.com/deskmatik/deskmatik#wiring-flexispot

Do you have any idea where I made a mistake? Is my control module possibly not compatible, since I also have only one Ethernet port?

Have you tried reversing the TX / RX cables? This is very messy always and I had those reversed many many times during the development. The PIN20 is a very important one as well, since this allows you to send commands.

Could you perhaps share more here about how you configured the cables and how you set up the ESPHome yaml?

The Raspberry Pi code could use some love by the way, I just used this during the testing. The ESPHome code should work and this is what I am currently using.

Happy to walk through it on Discord as well, iMick#1903.

May something about the two Warnings?

@staxDB I just discussed this issue briefly with @lordfiSh and he is indeed facing similar issues. Looking at DeskMatic, it seems that they set the PIN20 to HIGH, where I use LOW.

Perhaps the following works;

  - platform: gpio
    name: "Virtual Screen"
    pin:
      number: D2
      mode: OUTPUT
    restore_mode: ALWAYS_OFF
    internal: true

Set restore_mode to ALWAYS_ON, or remove the internal and toggle it yourself during testing.

[staxDB]

I just tried the customization: It seems to work! However, I have also changed the PIN assignment:
PIN20 = D5
RX = D7
TX = D8

[iMicknl]

@staxDB are you able to do a pull request on this repo to add better instructions for HS01B-1? I will investigate the ALWAYS_ON/ ALWAYS_OFF differences between our model and document that in a better way.

[iMicknl]

Should be fixed with new ESPHome sample, thanks @staxDB.
