Hello. I have white LED strip (WS2811, 24V, 60 LEDs) and I try to make my own driver on ESP32. I use example and works fine, but…
I want to make effect on turn_on and turn_off. Effect is running light 1->60 on turn on and 60->1 when turn off. Turn on case is easy and works fine, but how to make effect before turn off the light? I tried to do it with chat gpt, but it is stupid like hell ;). Maybe someone has some example?
Best regards

Post what you already have [properly formatted </>].
If it can count up, it can probably count down too.

Your code is missing power_off script
script:
- id: power_on_effect
mode: restart
then:
- light.turn_on:
id: ws2811_white
effect: on_sweep
- delay: 1600ms
- light.turn_on:
id: ws2811_white
effect: none
- id: power_off_effect
mode: restart
then:
- light.turn_on:
id: ws2811_white
effect: off_sweep
- delay: 1600ms
- light.turn_off:
id: ws2811_white
And that the reason I’m here. This simple solution doesn’t work. I also tried many others with chat gpt, but it doesn’t know what to do at all 
Maybe someone here has a right solution?
“Doesn’t work” is not any helpful here.
You wrote your turn on code works. So what’s the exact misbehavior with turn off ??
If you have used the code that you have posted yourself where you quoted Karosm their post, it’s normal that this happens.
In the same ‘then’, you have turn_on and turn_off…
There’s 1.6s delay between…

Explain the behavior, post always logs with code tags (not screenshots) and set all transition lengths to 0.
It doesn’t help or it is not properly transition. Key word transition_length is invalid for light.esp32_rmt_led_strip]

Why don’t you finally tell what happens, what doesn’t and what you expect.
Your log prints correct sequence with correct time frame:

Why it’s repeated several times, only you know.
That’s harder to debug, syntax is on documentation and should be valid…
It seems to be logical to make some effect before turning off the light but it isn’t in real life. I think, it’s not possible to do it in ESP Home and esp32_rmt_led_strip.
