I’ve bought a Ledvance smart ceiling lamp that has a main light and a colored backlight.
I´ve connected it to Smart Things and then integrated it to HA since the Tuya app gives me a timeout error.
I have full access in the Ledvance app but in ST and HA I just cant increase the intensity of the color…
Its stuck in this part (se image) and wont extened further out.
I´ve tried changing every setting i can think off, both trough the ST developer site, HA card and HA developer services. It just wont make it more intense. Any ideas? 
This are the states available in HA:
min_color_temp_kelvin: 2000
max_color_temp_kelvin: 9009
min_mireds: 111
max_mireds: 500
supported_color_modes: color_temp, hs
color_mode: hs
brightness: 28
hs_color: 288, 88
rgb_color: 210, 30, 255
xy_color: 0.326, 0.132
friendly_name: Orb 1
supported_features: 32
This are the states available in ST:

I dont have an answer for you but I can localtuya supports setting values to individual data points.
You can figure out respective data point on the device and expected data format and call localtuya service.

Forget about it, this was all about tuya
Since i have 2 lamps in the same hallway i created a automation within the Ledvance app with the trigger:
“Lamp 1 = off, Lamp 2 = on”. When this combination is true, the automation is triggered and the exact colors, brightness etc is set trough the Ledvance app.
I then just made the button in HA turn Lamp 1 off and Lamp 2 on. Not the prettiest solutions but it works.
I will try your suggestion tho, since Ledvance is a Tuya product.
I´ve tried this, but this works worse than the Smart Things integration
