Additional information
I was hoping to setup an automation which aligns the brightness preset level to a switch in the same room (HS220) but there isn't a brightness preset level entity for the KP405. I tried standard troubleshooting measures like removing/readding and etc. but no such luck. It is as if the template for the KP405 simply doesn't recognize that it supports brightness functionalities/capabilities. Thanks for your time & efforts!
