Light effect on a button push

ESPHome
1

Hi

I am using an ESP for a small Model Kit and want to make it controllable within HomeAssistant.
Now, the basics are working fine - I do have my Lights which can be turned on and off from HomeAssistant and also via a physical “touch interface”…

Now, I want to extend this a bit - but yet, I haven’t really figured out, how this could be implemented:

  1. HA should provide a button
  2. This button should only be available, if the Lights are on
  3. When the button is pressed, the lights should enter a random / flickering sequence for a couple of time → and then, turn off.

Based on an example I found when I did some experiments with my S3 Box and Voice Assistant, I THINK, that should be acheivable with scripts … ?
At least, in this example, whenever the wakeword was detected and the device entered the “listening mode”, the display started to flash as long as the device was listening.

So I think, that could be a start for getting the configuration done - but I am not able to change the configuration accordingly to my requirements.

Here’s the example code:

# this is when the wake-word switch is turned off ... then you can use the top-left button to activate listening
  - platform: gpio
    pin:
      number: GPIO0
      mode: INPUT_PULLUP
      inverted: true
    name: Top Left Button
    disabled_by_default: true
    on_click:
      - if:
          condition:
            switch.is_off: use_wake_word
          then:
            - if:
                condition: voice_assistant.is_running
                then:
                  - voice_assistant.stop:
                  - script.execute: reset_led
                else:
                  - voice_assistant.start:
          else:
            - voice_assistant.stop
            - delay: 1s
            - script.execute: reset_led
            - script.wait: reset_led
            - voice_assistant.start_continuous:

      - lambda: id(va).set_use_wake_word(false);
      - script.execute: reset_led

Maybe, someone from the more experienced users here can help me with this?

Thanks in advance :slight_smile:

OK, I got a first result without any condition…

pretty straight forward with a button, that calls “light.turn.on” with an effect, then a delay and then light.turn_off…

This is now working when the lights are off, then, it turns them on with effect - and when the lights are already on, it just enters the effect mode…

as far as I got, there’s no condition for “on_press” actions…
It’s not exactly, what I was looking for, but for now I can live with this limitation :slight_smile:
