Dimmer Switches with Transition?

I would like to purchase a dimmer switch for my wall that has the ability to slowly dim my lights when I start playing some media. Is there a particular switch people recommend? I’ve seen that some dimmer switches don’t support the transition element so that’s why I’m struggling with which one to buy. Something without a hub would be great but if that’s what I have to get then that’s what I’ll have to get!
