Thank you to @iMicknl for helping me out with this! I´d like to share my working setup with others :)

Please add the following code at the botton of the yaml-file if you want to have a position control in Home Assistant. The Position-range is from 0% to 100% and you can use it with alexa like "set desk to 70%" if you populate the cover-entity to alexa (i did it with Nabu-Casa).

    # Move desk to desired position
    position_action:
    #Check if we need to move desk up or down from current position
      if:
        condition:
        #Current height is more than target height, then move desk down
          lambda: |-
            float position = (float(id(desk_height).state) - float(${min_height})) / (float(${max_height}) - float(${min_height}));
            return pos < position;
        then:
          - logger.log: "Schreibtisch muss runter gefahren werden"
          - while:
              condition:
                # Move down till the current height is smaller then the target height
                lambda: |-
                  float position = (float(id(desk_height).state) - float(${min_height})) / (float(${max_height}) - float(${min_height}));
                  return pos < position;
              then:
                - logger.log: "Executing down command"
                - cover.template.publish:
                    id: desk_cover
                    current_operation: CLOSING

Picture of my setup

Voice-Control with Alexa
You can control your desk via Alexa now. To do so, expose the button.sit and button.stand to alexa (i use Naba Casa for this). In the Alexa App i createt 2 routines that trigger the "Sit" and "Stand"-Scenes with a Voice command like "Alexa, im stehen arbeiten" (Alexa, work standing).

Hi @guevara777 , in the image you connect GPIO 18 and 19, but in the code you define the tx and rx for 16 and 17. Is that just a typo?
I'm using the exact same devices but I can't get this setup to work...

The Image is wrong. In the code it´s right. I use the GPIO-Pins 16 and 17 like this:

uart:
  id: desk_uart
  baud_rate: 9600
  tx_pin: GPIO17
  rx_pin: GPIO16

Here is the correct wirering:

I also added a position-action since i posted it here. You can populate the cover to Alexa and use voice commands like "set the desk to 70%".

for this you have to add this to the yaml-file:

    # Move desk to desired position
    position_action:
    #Check if we need to move desk up or down from current position
      if:
        condition:
        #Current height is more than target height, then move desk down
          lambda: |-
            float position = (float(id(desk_height).state) - float(${min_height})) / (float(${max_height}) - float(${min_height}));
            return pos < position;
        then:
          - logger.log: "Schreibtisch muss runter gefahren werden"
          - while:
              condition:
                # Move down till the current height is smaller then the target height
                lambda: |-
                  float position = (float(id(desk_height).state) - float(${min_height})) / (float(${max_height}) - float(${min_height}));
                  return pos < position;
              then:
                - logger.log: "Executing down command"
                - cover.template.publish:
                    id: desk_cover
                    current_operation: CLOSING
                - uart.write:
                    id: desk_uart
                    data: [0x9b, 0x06, 0x02, 0x02, 0x00, 0x0c, 0xa0, 0x9d]
                - delay: 108ms
        else:
          - logger.log: "Schreibtisch muss hoch gefahren werden"
          - while:
              condition:
                # Move up till the current height is bigger then the target height
                lambda: |-
                  float position = (float(id(desk_height).state) - float(${min_height})) / (float(${max_height}) - float(${min_height}));
                  return pos > position;
              then:
                - logger.log: "Executing up command"
                - cover.template.publish:
                    id: desk_cover
                    current_operation: OPENING
                - uart.write:

Hi guys. If I add the second part (Move desk to desired position) i get a double definition error from position_action.

I‘m a noob in coding and do need help there. Can anyone help me?
