Home Assistant - RGB Light with Home Kit Bridge

Help me create a simple Virtual RGB LED light that is visible in Home App (via Home Kit Bridge).

I have code as follows but it doesn't work when changing the colour in Home App, the values don't change in Home Assistant. For a simple dimming white light via Home App it does update in Home Assistant however.

input_number:
rgb_light_strip_red:
name: "RGB Light Strip Red"
min: 0
max: 255
step: 1

input_number:
rgb_light_strip_green:
name: "RGB Light Strip Green"
min: 0
max: 255
step: 1

input_number:
rgb_light_strip_blue:
name: "RGB Light Strip Blue"
min: 0
max: 255
step: 1
