ESPHome switch not showing up

skate7789 · April 22, 2024, 11:50am

Hello! I am having a problem with my GPIO switch not showing up as an entity in HA. Can anyone help me? Thanks!

Code:

esphome:
  name: garage_door_opener
  platform: ESP32
  board: nodemcu-32s

logger:

wifi:
  ssid: "SSID"
  password: "PASS"

api:

switch:
  - platform: gpio
    pin: 22
    id: garage_door_button

script:
  - id: trigger_garage_door
    then:
      - switch.turn_on: garage_door_button
      - delay: 3s
      - switch.turn_off: garage_door_button

I basically need to power on a pin on my ESP32 board for 3 seconds, to activate my garage door remote, thats it, but the switch entity is not begin detected.

If you only give your switch (or any component) an id and not a name it will be internal to the ESP only and not shared with HA.

Give it a name and it will show up in HA:

switch:
  - platform: gpio
    pin: 22
    id: garage_door_button
    name: Garage Door Button

tom_l · April 22, 2024, 11:57am

Note there is a better way to do this. Delete the switch and script and use a button instead.

output:
  - platform: gpio  # Internal to the ESP
    pin: 22
    id: garage_door_button

button:
  - platform: output # Shared with HA. 
    name: "Garage Door"
    output: garage_door_button
    duration: 3s # does it really need to be pressed this long?

But now I am seeing with the button solution, that pin 22 or “D22” on the board is powered on, not doing anything when I press the button, it should only be powered on if someone presses the button in HA, and also then for 3 seconds.

esphome:
  name: garage_door_opener
  platform: ESP32
  board: nodemcu-32s

wifi:
  ssid: "SSID"
  password: "PASS"

api:

output:
  - platform: gpio
    pin: 22
    id: garage_door_button

button:
  - platform: output
    name: "Garage Door"
    output: garage_door_button
    duration: 3s

internal (Optional, boolean): Mark this component as internal. Internal components will not be exposed to the frontend (like Home Assistant). Only specifying an id without a name will implicitly set this to true.

It applies to all & any components, so far I know.

Hello fellow people!

I am currently making a system where I can control my old garage door system, by doing some soldering on my remote and the ESP32 board, and I have got it working so if I power pin 22 on my remote, the door opens.

I am seeing, that pin 22 or “D22” on the board is powered on, not doing anything when I press the button, even tough it should be only powered when the button is pressed and also then for 2 seconds.

Can someone help me? Code is attached below.

esphome:
  name: garage_door_opener
  platform: ESP32
  board: nodemcu-32s

wifi:
  ssid: "SSID"
  password: "PASS"

api:

output:
  - platform: gpio
    pin: 22
    id: garage_door_button

button:
  - platform: output
    name: "Garage Door"
    output: garage_door_button
    duration: 3s

You mean pin 22 always providing power (state on) after board is powered on ?
Would be nice to have debug output to see styte changes of button & output.

logger:
  level: DEBUG

Added logs

steriku · April 22, 2024, 3:32pm

I’ve used a switch for this purpose and it it works well.

switch:
  - platform: gpio
    pin: 
      number: GPIO14 # D5
      mode: output
      inverted: true
    id: north
    name: "Garage Door North Button"
    icon: "mdi:garage"
    on_turn_on:
    - delay: 500ms
    - switch.turn_off: north

Masterzz · April 22, 2024, 4:43pm

Also while button pressed too, not only configuration.

nickrout · April 22, 2024, 7:56pm

22 is not the same as D22.

nickrout · April 22, 2024, 8:24pm

You do realize that 22 (which is short for GPIO22) is not the same as D22.

tom_l · April 22, 2024, 11:26pm

There was no need to start a new topic about this. I have merged them.
