Novice question help - direct brightness control from tp-link wall dimmer switch to control directly a tp-link outdoor dimmer plug?

Sorry if this has been answered, or if posted in the wrong place but…

Novice to HA. Fun to learn in HA(not really) but nonetheless -
Ive got a TP-LINK Tapo smart dimmer switch (S505D) integrated on HA through matter, and an outdoor dimmer plug controlling my patio lights TP-LINK Kasa (KP405)

  • have them both connected on the tp-link app and on HA too. I have the automation working great to toggle the lights on the dimmer plug using the in wall dimmer switch. But my issue:

  • the dimmer plug dims the lights perfectly using the app of course and using the HA card slider. But I WANT TO USE THE DAMN IN-WALL SMART DIMMER -/+ BUTTONS TO ALSO CONTROL THE BRIGHTNESS OF THE LIGHTS PLUGGED INTO THE OUTDOOR DIMMER PLUG. Why this so hard?
    Pls, any help or hope?

  • tried attaching a tiny video showing, but forum doesnt accept iphone videos? & im only allowed one picture i guess?

.

  • the automation im using currently - the main switch has physical dimmer buttons but doesnt have a dimmer option on HA
  • Smart dimmer plug does on the other hand show options for brightness actions in HA.
