Esphome gpio.switch status on OLED display

ESPHome

Hello Everyone,

I would like to ask some help from you because I cant make a valid config for this use case.

I need to print every gpio switch status on my oled screen, but every type of get this class I dont have success.

This is my conf:

switch:
  - platform: gpio
    pin: GPIO32
    inverted: yes
    restore_mode: RESTORE_DEFAULT_OFF
    name: "CH-1"
    id: ch_1

display:
  - platform: ssd1306_i2c
    model: "SSD1306 128x64"
    id: my_display
    address: 0x3C
    update_interval: 2s
    pages:
      - id: page1
        lambda: |-
          it.printf(10, 10, id(roboto), "CH1 status:", id(ch_1).state ? "on" : "off");

Thanks in advance for any kind of help!

Did you see/try this from the examples?

binary_sensor:
  - platform: ...
    # ...
    id: my_binary_sensor

display:
  - platform: ...
    # ...
    lambda: |-
      if (id(my_binary_sensor).state) {
        it.print(0, 0, id(my_font), "state: ON");
      } else {
        it.print(0, 0, id(my_font), "state: OFF");
      }
      // Shorthand:
      it.printf(0, 0, id(my_font), "State: %s", id(my_binary_sensor).state ? "ON" : "OFF");

It’s work~ish but wont update the status, so when start the esp the display shows State: OFF and dont refresh when I chage the status.

@Mahko_Mahko

Thanks for your help, if you have some time for me please help me a little… How can make a trigger or automation or update interval for this binary sensor to reach the status change because this boolean never be change after creation.

Thank you so much

Are you able to display and refresh something else simple?

Like uptime?

Try it.

binary_sensor:
  - platform: .....
    on_state:
      - component.update: display_lcd

display:
  - platform: .....
    id: display_lcd

@Mahko_Mahko, @Miki_Spetik

I tried the uptime sensor and the on_state as well.
The uptime sensor dont shown on the screen but every other thing are work perfectly.
The on_state dont work neither when configured, the switch doesnt react to the switching, but the display shown the state ON :smiley:

I insert my config maybe you see some big rookie mistake

      on_press:
        - switch.toggle: ch_1

and of course edit

it.printf(3, 16, id(roboto), "CH1:%s", id(ch_1).state ? "ON" : "OFF");

Sorry for three quick edits.

And uptime missing %i

it.printf(2, 10, id(roboto), "Uptime:  %i", id(uptimes));

@Miki_Spetik

I tried both of your option and the displayed status change is ok now, but the GPIO pin dont make change that is, the relay doesn’t switch.

I can’t imagine why the binary sensor affects the switching in this way.

Thanks you for your support and don’t worry about how many times you edit the post :smiley:

P.S.: The uptime sensor is OK right now. Thanks.

Now I tried esp32 and relay and lcd - ok.
The button changes the relay status and the LCD shows the relay status.
Is there a fault in the wiring?

12

Ooooh. You have the same pins for binary_sensor and switch ! This is wrong. GPIO always use one pin.
:slight_smile:

13

Sorry but i dont catch this :smile:
The binary sensor represent the relay outputs gpio’s and the gpio config just plachold to one non used pin?

14

GPIO binary_sensor is input (button), GPIO switch is output (relay). You can’t have both on one pin.
If you don’t have a physical button, try it.
Delete binary_sensor and:

switch:
  - platform: gpio
    pin: GPIO32
    inverted: yes
    restore_mode: RESTORE_DEFAULT_OFF
    name: Relay 01
    id: relay_01
    on_turn_on:
    - logger.log: "Switch Turned On!"
    - component.update: display_lcd
    on_turn_off:
    - logger.log: "Switch Turned Off!"
    - component.update: display_lcd

display:
    - platform: .....
      pages:
        - id: page1
          lambda: |-
            //State gpio output
            it.printf(3, 16, id(roboto), "Relay 01:%s", id(relay_01).state ? "ON" : "OFF");
15

Oh ok I see.
I’ll try in the morning and get back to you!

I think now understand, many thanks for the help and the teaching!

Hello @Miki_Spetik

I tried like this:

switch:

  - platform: gpio

    pin: GPIO32

    inverted: yes

    restore_mode: RESTORE_DEFAULT_OFF

    name: "CH-1"

    id: ch_1

    on_turn_on:

      - component.update: my_display

    on_turn_off:

      - component.update: my_display

...........

it.printf(3, 16, id(roboto), "CH1:%s", id(ch_1).state ? "ON" : "OFF");

And get from esp this:

The Wifi sensors are commented because the value displaying faulty as well

Remove all

on_turn_on:
      - component.update: my_display
    on_turn_off:
      - component.update: my_display

Probably many request component.update.
I will try to analyze later.

Hi @Miki_Spetik

When I deleted the mentioned lines the code start to work, and the status change on the display as well!
Thank you very much for your help and @Mahko_Mahko thank you too!

I have only one question or topic in this use case.
I would like to display all wifi sensor as well like:
Used SSID:
MAC:
IP:
Signal strenght:

But with this config doesnt ok:

# text_sensor:
#   - platform: wifi_info
#     ip_address:
#       id: ip_addr
#     ssid:
#       id: ssid
#     bssid:
#       id: bssid
#     mac_address:
#       id: mac_address
#     scan_results:
#       id: scan_res

# sensor:
#   - platform: wifi_signal
#     id: signyal
#     update_interval: 5s    

# display:
.
.
      # - id: page2
      #   lambda: |-
          # it.printf(2, 10, id(roboto), id(ip_addr->toString()));
          # it.printf(2, 20, id(roboto), id(ssid->toString()));
          # it.printf(2, 30, id(roboto), id(mac_address->toString()));
          # it.printf(2, 40, id(roboto), "Signal DB", id(signyal->toString()));

Thats why I commented the lines. What I’m doing wrong what is the good approach.
