K868-Uair proper GPIO assignation ? - vincen - 03-09-2022

Hi

I'm tyring to use a K868-Uair with ESPHome but I have some problems ! According at Kincony ducomentation it should GPIO32 and 33 to control RGB LEDs of bottom ring and vertical bar ! Unhappy these two GPIOs are doing exactly the same thing: control the ring only and only 3 LEDs of it Sad

Sad

Someone has the proper GPIO configuration of that board ?
Noticed also that the Dallas temperature sensor is a chinese copy I think as it's 4/5° offset of other temperature sensors I have in the room Sad

Sad

Code used so far in ESPHome for LEDs:

Code:
light:

  - platform: neopixelbus

    type: GRB

    variant: WS2812X

    pin: GPIO33

    num_leds: 4

    name: "Barre"

  - platform: neopixelbus

    type: GRB

    variant: WS2812X

    pin: GPIO32

    num_leds: 4

    name: "Ring"

Thanks for help

GPIO33 use for 1 LED
GPIO32 use for 4 LED

GPIO33 use for 1 LED
GPIO32 use for 4 LED

Thanks for code it works this way but it's using old RGB implementation mode of ESPHome Wink

In fact the device has a hardware issue as one of the ring LED is wired with bar so only 3 LEDs of ring work together, the other one works with bar which kills the visual effect of the ring !! Are you aware of that problem on the device ??

no, 4 LEDs work together with ring LED. another one LED is indepentant. here is diagram, you can see details.

Thanks for the schematics but it doesn't correspond with reality ! Have a look at my picture you can clearly one of the LED is not following the other ones on ring but the ones of bar Sad

do you use my code directly? or changed something?

i think you need to check software, hardware is no problem, here is some our demo images.
