Question about Tuya Multicolor

Configuration
1

Good evening,

First of all, please excuse my bad English and have a good start into the new year :smiley:
I installed the Tuya integration in HomeAssistant and connected everything.
Unfortunately I have an error in one of my devices (Battletron Light Ball).
The ball has 2 color zones, unfortunately when controlling the color and brightness only the upper half of the ball is changed. The lower zone always remains a purple. Is there a way to fix this? Attached are two more pictures to understand what I mean.

Best regards
Julian

Got the same problem. After changing color in Home assistant it only changes color for the top half. I noticed that the values in the tuya app for the bottom half also changed but to values that are not supported. For example: brightness = 307%

3

Now that you mention it, I noticed it too. I have already tried to connect them via the local Tuya integration. For this I got the local key via tuya iot. However, the message appears that the connection was successful but no datapoints could be found.

4

I connected the light over tuya with google home (without home assistant). Its the same here. I can only control the top half and when i change the brightness the bottom half changes to 100%.

Has there been any progress with this? As others here I can control the top half with the standard light.turn_on function but not bottom:

service: light.turn_on
data:
  color_name: cyan
  brightness_pct: 100
  device_id:
    - 741680f7bbf68b70d7b9d737a1fb1c6d

If somebody more versed in delving into the function behind light.turn_on could provide some pointers with how we can control the bottom half progmatically (i.e. what’s happening under the hood) I’m happy to provide some debug info?

I’ve logged into the Tuya IOT debug platform as the following is available:

}

looking at the device logs I get this when I change the colour via the Tuya app (which can control the top and bottom of the light)

and when via home assistant:

Is there a standard way to have this looked into?
