Hue Brightness feedback

[NKereshki]

Hello. 

A few months ago, I integrated Philips Hue lighting fixtures that support dimming, color temperature change, and RGB. Everything works perfectly, except I hadn't set up the feedback for the light fixture's state if you change it from the Philips Hue app. Before posting on the forum, I carefully reviewed all topics related to this issue. I am using "user.hue v5.lua" and "resident hue feedback v2.lua". The on/off, dimming, and RGB feedback work perfectly. However, neither the color temperature change itself nor its feedback are working correctly. For example, I set 2000K from W4K, and in the Hue app, it shows a completely different color. The feedback also doesn't work. When I disable the feedback script, the color temperature control works correctly. I am using the following script. Please help me find where I am going wrong. I have spent over 2 days on this problem without a resolution.

Code:

-- Set name (Lookup in HUE app under light configuration) and feedback adresses (don't change statevalue, brivalue and colorvalue as they are used as memoryfield)
addressmapping = {
  -- Name                  -- On/Off FB       -- Bright FB   -- Color FB
  ['Cove lighting-cr'] = {state = '1/0/9', bri = '32/2/9', rgb = '32/3/9', ct = '32/4/9', statevalue = '', brivalue = '', colorvalue = '', ctvalue = ''}
}
