Garage Door and wired I/O expander for RPI4

Hello You all.

I have RPI4 With HA Core (0.106.5) that will be sitting in a attic. I have also garage. I am really determined to control them by wire because this is most important (country) house entrance.
Distance between these two points is about 15-20 m. For that I decided to use Waveshare MCP23017, but of course distance is to great. Sice I have Nice Spido drive that has limit switches i decided to monitor 2 binary sensors to get 3 states (closes, opened, unknown). Drive has “start-stop-reverse logic” input and I am fine with that.
Also i would like to achieve really minimalistic thing: one icon representing state of gate, name and one switch.
After reading this topic i noticed that it is closest to my desired but i was not able to control button image with sensor state.
After reading this other solutions i had also problem with setting this cover as switch with “toggle script”
Finally i used this solution, but it has minimum of two buttons. I can live with that but it is arguing with logic of gate driver input (“start-stop-reverse logic” = toggle).
Now it looks like this:

cover:
  - platform: template
    covers:
      garage1_door:
        friendly_name: "DRZWI LEWE"
        icon_template: >
          {% if is_state('binary_sensor.garage_door_13', 'on') %}
            mdi:garage
          {% elif is_state('binary_sensor.garage_door_12', 'on') %}
            mdi:garage-open
          {% else %}
            mdi:garage-alert
          {% endif %}
        open_cover:
          service: script.garruchlewe
        close_cover:
          service: script.garruchlewe
      garage0_door:
        friendly_name: "DRZWI PRAWE"
        icon_template: >
          {% if is_state('binary_sensor.garage_door_15', 'on') %}
            mdi:garage
          {% elif is_state('binary_sensor.garage_door_14', 'on') %}
            mdi:garage-open
          {% else %}
            mdi:garage-alert
          {% endif %}
        open_cover:
          service: script.garruchprawe
        close_cover:
          service: script.garruchprawe

I know that in practice this topic will is, a little bit about hardware. But I want to keep this expander in garage because i will be adding few things and I don`t want to drag all those wires to attic itself. I do not want to use any complicated system such as arduino as I/O communicating with RPI by RS and that is because I am new to pretty much all of it.

1. Is there any other wired solution ? - If no I will just use P82B715P - I2C expander.
2. Does anyone know how to change Input/Output direction for i2c?
3. Does anyone have an idea how to achieve what I made with cover.template but in button minimalistic form ?

PS Thanks to my friend “SZU” that lured me into this HA community
