Is Alexa able to reply the state of a KNX Dimmer? ON/OFF, Brightness

Thank you Jeremy,
but after 5 hours reading through the docs: State derived groups will be considered as single endpoints based on their defined group type.
And remembering your post: Best way to publish Groups to Alexa?
I’m really sorry, but I have to ask again.

I tried with

value: Switch.PowerState,Switch.ToggleState
config:
  OFF: Off (what to put here???)
  ON: On
  capabilityNames:
    - Status

The Alexa command to switch the lights ON and OFF work, but if I ask Alexa, “what is the Status of Lichter im Haus?”,
or Alexa “are Lichter im Haus on?”
I always get: " Lichter im Haus does not support that "
:sob:
