Esp8266 as a wifi button

Hi,
i’m new with home assistant and I’d like to create an automation that toggle my switch when I push the button on my Esp8266.

I just flashed the esp8266 firmware with EspHome.

My problem is that I can’t create an automation that trigger the light switch when I click the button on my esp8266.

Here is the code:

---CODE INSIDE MY ESP8266:---
 
binary_sensor:
  - platform: gpio
    pin: 4
    name: "PulsanteD2"
    device_class: lock

---AUTOMATION CODE THAT DOESN'T WORK:---
 
alias: Turn On
description: ''
mode: single
trigger:
    - platform: state
      entity_id: binary_sensor.pulsanted2
      from: 'off'
      to: 'on'
condition: []
  action:
    - service: switch.toggle
      entity_id: switch.1000a595a6

What does the esphome log say when you press the button?

What does state of the binary sensor say when you press the button?

It’s a little bit strange, because i don’t see anything in the log and the binary_sensor show the status “locked or unlocked” but random.

Sounds like it is floating, what exactly is your wiring?

5

The wiring is port D2 with GND. I saw that the port D2 on my nodemcuv3 is the GPIO 4.

In my esphome code says that my board is esp01_1m.

6

That is correct. So your button shorts D2 to ground? I think you need pullup GPIO Binary Sensor — ESPHome

7

So like this:

binary_sensor:
   - platform: gpio
     pin:
  number: 4
  inverted: false
   mode:
    input: true
    pullup: true
name:
"PulsanteD2"

I tried with this code, but when I release the button, the state goes to off

8

No, your indentation is wrong. See the example I pointed you to.

9

Thank you so much for the example, but I don’t know if I understood what to do.

So I set “pullup” to false and now when I click the button, the state goes from on to off and stop it…

10

I created the automation that when I click the button the light goes on.

Now the problem is how to stuck the state of the button on “ON” when I push the button and “OFF” when I push again the button

11

The toggle automation in your first post should do that.

12

I don’t know why but the automation doens’t work with switch.toggle.
So I created 2 automation, 1 to turn on the light and 2nd to turn off the light.

But when I press the button, the state of the binary_sensor goes to On and again to off

13

You are really confusing me. Please post your current config for both the esphome and the HA automation.

I’m sorry about that :sweat: I have a bad english grammar.
Anyway I just saw that it was a eWelink bug, so the switch.toggle didn’t work fine.
So I found that there is a script that basically Turn on the switch when the switch is off and vice-versa.

So I created the automation that when I push the button then execute the script.
