RGBW light, cannot change to white

Configuration Frontend

Hi, since 2023.03 and new light dialog, i cannot change to white leds on my RGBW lights.
When i click into middle white spot, i can see in esphome log, that it receives

[22:45:50][D][light:035]: 'zemismart_bulb_a19_002_light_rgbw' Setting:
[22:45:50][D][light:054]:   Color brightness: 100%
[22:45:50][D][light:057]:   Red: 100%, Green: 100%, Blue: 100%

hence it uses rgb white, not white leds.

My bulbs use this config for lights

light:
  - platform: rgbw
    id: light_01
    name: "${dev_name}_light_rgbw"
    default_transition_length: 0s
    color_interlock: true
    red: output_red
    green: output_green
    blue: output_blue
    white: output_white
    effects: !include ../../.common/light_effects_01.yaml

my9231:
  data_pin: GPIO13
  clock_pin: GPIO15
  num_channels: 4
  num_chips: 1
#  bit_depth: 14

output:
  - platform: my9231
    id: output_blue
    channel: 1
  - platform: my9231
    id: output_red
    channel: 3
  - platform: my9231
    id: output_green
    channel: 2
  - platform: my9231
    id: output_white
    channel: 0

When updating to home assistant 2023.03, I also compiled latest esphome firmware and switched to api key encryption.
Now there is also another problem with those bulbs, the lights does not react properly to on/off.
I see, it receives

[22:53:58][D][light:035]: 'zemismart_bulb_a19_002_light_rgbw' Setting:
[22:53:58][D][light:046]:   State: OFF

But it stays on.
I don’t know how to debug this, clearly it receives the command to switch off

I am having the same issue with the update to 2023.3.x

I have a few Wyze lights with ESPhome using RGBW light platform and the option to choose white is gone. When I revert back to home assistant 2023.2.x I get the option to change to the white light, but the temperature slider is still missing. If I change the interlock option to false, I can control the white light in the 2023.2.x and 2023.3.x but I would like to have it return to what it was before I updated.

Issue returned/came back/showed up again in 2024.4.0 for 1 of the Tuya light bulb types I use. This has screwed with dimming automation where instead of dimming, the light now changes color…
