@Mahko_Mahko They are pulled momentarily.

But I figured it all out. The 0.8v was indeed just a regular LOW signal.
Here’s the ESPHome configuration to allow me emulating any button on my Uplift Desk:

output:
  - platform: gpio
    pin: GPIO21
    id: pin_7_green
    inverted: true
  - platform: gpio
    pin: GPIO22
    id: pin_8_yellow
    inverted: true
  - platform: gpio
    pin: GPIO17
    id: pin_6_purple
    inverted: true
  - platform: gpio
    pin: GPIO16
    id: pin_1_transparent
    inverted: true
    
button:
  # Simple Buttons
  - platform: output
    output: pin_7_green
    name: Up
    duration: 300ms
  - platform: output
    output: pin_8_yellow
    name: Down
    duration: 300ms
  - platform: output
    output: pin_6_purple
    name: 2
    duration: 300ms
  - platform: output
    output: pin_1_transparent
    name: M
    duration: 300ms
  # Combination Buttons
  - platform: template
    name: 1
    on_press:
      then:
        - output.turn_on: pin_7_green
        - output.turn_on: pin_8_yellow
        - delay: 300ms
        - output.turn_off: pin_8_yellow
        - output.turn_off: pin_7_green
  - platform: template
    name: 3
    on_press:
      then:
        - output.turn_on: pin_6_purple
        - output.turn_on: pin_8_yellow
        - delay: 300ms
        - output.turn_off: pin_8_yellow
        - output.turn_off: pin_6_purple
  - platform: template
    name: 4
    on_press:
      then:
        - output.turn_on: pin_6_purple
        - output.turn_on: pin_7_green
        - delay: 300ms
        - output.turn_off: pin_7_green
        - output.turn_off: pin_6_purple

The GPIO outputs are named in line with this layout:

Obviously the Up and Down buttons would better be switches, rather than buttons. Good enough for demonstration purposes though.
