Change Dimmer Curve In Lights

Configuration

Hey, right now when i click a button my lights turn on and off but i want to add a proper fade. I saw that HA has a transition time option but i feel like the dimmer curve is not good. Is there a script or blueprint that will allow me to change the dimmer curve? I also would like to know how i would implement it into a toggle on/off automation

Ashley’s Light Fader 2.0✨: fade lights and/or color temperature with your choice of easing (curves), including ease-in, ease-out, and ease-in-out.

It hasent worked well with my smart bulbs. Is there a config i should use?
