Very quick button presses only register on device but not in Home Assistant

[markusressel]

Hey there,
very cool product!

I noticed that when trying to adjust the brightness of a light using a button on the LocalDeck, pressing the button for a very short amount of time lead to the expected pulse animation on the button, but no resulting change in the brightness of the light. While the hardware did register the event and played the animation, the binary_sensor on the Home Assistant side stayed "off" the whole time.

I found this post: https://www.facebook.com/groups/HomeAssistant/posts/4227071614230843/
which suggest that this is a "batching" mechanism of the native ESPHome API, which by default debounces state changes within a 100ms time window.

This can be disabled using the following YAML:

api:
  # fixes very brief button presses only registering on-device but not within Home Assistant
  batch_delay: 0ms

See: https://esphome.io/components/api/#configuration-variables

I would recommend to add this to the ESPHome YAML Template for the LocalDeck, because it not only makes the device respond much faster (feels much snappier), but it also doesn't drop inputs that are indicated as "detected" by the pulse animation.
