ESPhome controlling a lot of blinds

ESPHome
1

Hi there,

I have 22 blinds that I would like to control using ESPHome. My system is centralized, with all the blinds connected to a central box in the house. For this setup, I’ve utilized one ESPHome board and MCP23017 GPIO expanders.

I have successfully created a working program for a few blinds, but now I need to scale it up to control all 22. While copying and pasting the code 22 times is an option, I prefer to do it in a more modular way.

I’ve tried using substitutions, and this is where I am currently. I have two files: one is the main configuration file, and the other is a general configuration file. In cover component, I do multiple includes and set proper variables for each include.
main.yaml

substitutions:
  open_duration: 10s
  close_duration: 10s
  mcp23017_adr_1: '20'
  mcp23017_adr_2: '21'

    pin:

      number: ${pin_key_down}
    inverted: false
    on_click:
      then:
        - cover.close: "roleta_${roleta_id}"

I’m brain-dead at this point, tried too many things, could not get it to validate. I even used chatgpt.
Main question for me now is, is it even possible to do this on ESPHome?

Thank you! I saw it before, but I dismissed it as a variant of substitutions. Since I’m weak in coding, the sample provided didn’t give me enough info. However, after revisiting it, I tried again, and after a few days it’s working now. I’ve pasted the code below in case it might be useful for someone else.

substitutions:
  open_duration: 10s
  close_duration: 10s

  mcp23017_adr_2: "0x21"  # 2nd MCP23017
