Hello.
I have that part of the yaml file

i2c:

     inverted: True

unfortunately gets a mistake

Failed config

light.gpio: [source bathroom.yaml:48]
  
  Platform not found: 'light.gpio'.
  platform: gpio
  name: wemos_bathroom - left bulb
  id: relay_1
  pin: 
    pcf8574: pcf_expander
    number: 4
    mode: OUTPUT
    inverted: True

what I’m doing wrong

2

Using a non-existent light platform. There is no platform: gpio for light.

The allowable light platforms are: https://esphome.io/index.html#light-components.

Thank You for the quick reply.
It is a pity that you can not be as GPIO.
So I’ll have to change the icon

greetings

I’m not sure what you mean by that.

Just use a binary light and point it at a gpio output.

I wanted to get the lamp icon at the switch in HA. It seemed to me that the easiest way to do this is to change the “switch” to “lamp”. As a last resort I did it by adding the “icon” option
icon: "mdi: lightbulb".
It worked, but now there is another problem :), because when the light is ON, the color of the lamp does not change

Thank You - it works!
My configuration look’s like this:
