3rd party: Homeassistant control panel; Dim lights?

Hi guys,

I recently installed: https://github.com/hassio-addons/addon-control-panel
Now this is a beauty to go with, but i’m struggeling to add sliders for dimming.

But, I kinda guess this isn’t possible. Do any of you guys know if it is possible?
because if it isn’t I need to migrate to HADashboard instead :frowning: would be to bad because this panel is amazing!

Thanks in common guys.
