HA + EspHome = WS2812B stairs project - delay error

ESPHome
1

Hello All,

I’ve combined a small project including HA, EspHome, WS2812B Led strips and Aqara motion sensors to light my 14step stairs. Everything work good except lightning each step that is taking 1second. Cant make it like 400ms. Below is my code, I know it’s chaotic but it works.

My automation:

Congiguration on EspHome is making how many leds are on each step.

While the documents say that milliseconds are valid (and they are) they don’t tell you that the minimum possible delay resolution is 1 second (1000ms). It’s just the way home assistant works.

Hmmm in that way i will be faster on top of the stairs than the light.
Maybe other solution for it like Lambdas in EspHome? But this is black magic for me…

I’m pretty sure ESPHome can do sub 1sec delays.

I don’t know what your esphome.yaml looks like, but maybe you could work with a Template Switch inside ESPHome and then do the automation for the lights in there.

Something like this (just a rough example to get the idea):

# Example configuration entry
substitutions:
  delay_value: 100ms

switch:
  - platform: template
    name: "Template Switch (schody_down)"
    turn_on_action:
      - light.turn_on: step14
      - delay: ${delay_value}
      - light.turn_on: step13
      - delay: ${delay_value}
      - light.turn_on: step12
      - delay: ${delay_value}
      ...

So in a simple way it could work without lambdas…

My configuration.yaml on EspHome looks like this:

          green: 100%

      - light.turn_on:

          red: 100%
          green: 100%
          blue: 0%

And the switch does nothing… I can light any step from Home Assistant but using EspHome cant do anything… Really need help

In addition i recive in log:
