History stats entity showing wrong value

I’m wondering why my history stats entity is showing a different value from what it actually is.

It counts correctly:

The entity value shows 0,73h.

- platform: history_stats
  name: Papa - Zeit zu Hause
  entity_id: person.papa
  state: "home"
  type: time
  start: "{{ now().replace(hour=0, minute=0, second=0, microsecond=0) }}"
  end: "{{ now() }}"

What do I need to do to get the correct value?
In the developer tools I see the following state attributes:

state_class: measurement
unit_of_measurement: h
device_class: duration
icon: mdi:chart-line
friendly_name: Papa - Zeit zu Hause
