Does it have to be a toggle switch?
A push button is more consistent intuitively, a switch can be perceived as on in a certain state.

If you want a toggle then you need to add automations to the GPIO pin like:


  on_turn_on:
    - switch.toggle: relay
  on_turn_off:
    - switch.toggle: relay

The above is perhaps not correct syntax, I just wrote it from what I remember.

Using a button you use on_press → switch.toggle.
No big deal whichever you use.

But you are correct in your thinking about having the switch on a separate pin, just remember to add pull-up or pull-down.

i use pin d7 for toggle swich (connect gnd pin to toggle and to pin d7)
i define d7 as a swich but when i turn on toggle swich on pin d7 status dont change

What yaml do you have for d7 pin?

its like that
switch:

  • platform: gpio
    pin:
    number: 13
    name: “toggle 1”
6

it says 13 here…

Remember to paste code inside a code block (preformatted text </>)or it’s much harder to find errors

pin D7 number is 13

Ok… got it.

try and make the pin pull-up:
GPIO Binary Sensor — ESPHome
This should make the pin on until the switch grounds it.
