Using zone & persons to switch Light

I’m using this automation yaml:

alias: Testlampe AN
description: ''
trigger:
  - platform: zone
    entity_id: person.wolli
    zone: zone.home
    event: enter
condition: []
action:
  - type: turn_on
    device_id: 59197117b1fb44fda08b35db91718fb1
    entity_id: switch.buerowolli
    domain: switch
mode: single

person “wolli” states are “home” or “not_home” this I checked
The lamp is also switch able, this I checked also

But why does the lamp not switch ON when the state of person.wolli
changes from not_home to home ?

Thanks for info…
