Describe the bug

Currently, there are places in the codebase where private attributes (those prefixed with an underscore) are accessed directly. This practice circumvents encapsulation and can make the code harder to maintain or refactor in the future.

Below are some examples where direct access to private attributes can be found and should be refactored:

---

Example 1: Access to _events in Hilo class

custom_components/hilo/init.py

if event_data := self._events.get(event_id):
    # ...
    del self._events[event_id]
# ...
if event_id not in self._events:
    self._events[event_id] = await self._api.get_gd_events(
        self.devices.location_id, event_id=event_id
    )
return self._events[event_id]

Example 2: Access to _hass in Hilo class

custom_components/hilo/init.py

parent_unit_state = self._hass.states.get(attrs.get("source"))

Other instances may exist across the codebase. Refactor by introducing getter/setter methods or other encapsulation-friendly approaches to access private attributes.

---

This change will improve the maintainability and robustness of the codebase.
