While I plan to revamp the app in the future, what you're doing now looks like the reason I wrote [RELEASE] Dimmer Button Controller (configure Pico to emulate Hue Dimmer or any button device to easily control lights). I didn't like having to choose the same lights for each action (I want all buttons on the device to control the same lights) and I wanted to emulate Hue's multi-press functionality on the Dimmer (something it appears you're doing with a variable, though possibly missing it's "reset after X time" feature). DBC does both (and a version I'm currently working on allows access to Hue scene so you don't have to specify CT and things manually--but my custom Hue integration is also required for that).
