Hi everybody!
I’m having some issues with my esphome config. I have a st7735 Display running on the ili9xxx component. Everything works finde so gar but i cannot find a solution for a dimmable backlight that can be Controller from HA.
When i Set up my device, i can switch the backlight on and off, but that’s all.
My yaml looks like this:

In HA, I have this entity:
I thought about adding a numbrr_inpu5 in HA from 1 to 100% to kinda trigger the backlight brightness, but nothing works.
Can anybode help me out?
Regards!
