Light bar through Tuya only affecting Backlight RGB, and not the front white-cold-warm light
Hi everyone
I'm trying to add a front light  (here is some discovery information too) 
on any plugin + this tuya official - it only affects the backlight (RGB) lights
through the smartlife app, I can control the back light and front light separately. 

Any idea what is missing here?
Information attached: discovery information on the product, screenshot of the iOS smartlife app - look at the bottom options, finally the information asked by this ticket to be added to.
