Hi Gods of HA,
I bring forth this following request where I intend to display a LED on Waveshare ESP32S3 1.8 Round Knob (Blue). Maybe like a halo effect. This should control / mimic a home assistant light entity. Looking for an way on how to establish this mapping.
Looking for an answer, thy lords.
Have you tried using the LVGL led widget?
I am currently using lvgl led widget. I am tying to expose a ha level light from the device. Problem is with lvgl platform, I do not know how to control the color temperature of led
There’s no colour temperature control as such, just colour (RGB) but that’s handled automatically when you link the LED to a light.
What part of that isn’t working for you?
I was wrong earlier. I had used the wrong attribute rgb instead of rgb_color in the automation blueprint that I using to sync the LED bulb and lvgl led. I am able to sync it now. But there is considerable lag in the update.
Personally I want to thank you @clydebarrow, for taking an interest to solve my problem and following this up. 
Appreciate your help here.
I want to close this thread as I found a solution. But there is another problem being discussed in this thread
thank you all. solved
