How to change a switch status - secondary_info

Configuration
1

Hi all,

how can i chance the status from the switch?
to “An” and “Aus” ?

My switch Config:

- platform: wake_on_lan
  name: "Computer NUC"
  mac: "94:C6:91:10:xx:xx"
  host: 192.168.178.xx
  turn_off:
    service: script.pc_off

My Output Config:

- entity: switch.basti_nuc
  secondary_info: last-triggered

Output Images:
hs-status_frage

hs-status_frage2

And the second question is:
How can i change the “switch button / toggle” to the “icon (power) button” ?

Thanks for Help!
