[bug] notification sensor doesn't get updated

[rkrkrk0987]

notification sensor doesn't get updated

there are no errors in home-assistant.log related to this component

to have better idea i extended log with log.info in in __init__.py number of notifications in fetch_data():

                _LOGGER.debug(f"INIT Coordinator fetch_data returning: {return_data}")
                _LOGGER.info(f"INIT Coordinator fetch_data returning length: {len(notifications)}")

and in sensor.py in class EduPageNotificationSensor state(self)

        """Return state."""
        _LOGGER.info("SENSOR state %s",len(self._notifications))
        return len(self._notifications)

and after while it is no longer the same number

2024-12-11 17:03:18.847 INFO (MainThread) [custom_components.homeassistant_edupage] INIT Coordinator fetch_data returning length: 199
2024-12-11 17:03:18.851 INFO (MainThread) [custom_components.homeassistant_edupage] SENSOR state 198

thanks for your feedback! I'm trying to reproduce and get an idea.

let me know if i can provide you with more details
in this case 3 times it was able to refresh data (30min as you defined) and 4th time sensor haven't received new data, and was working only with old data... and haven't recovered, so it is still unable to receive current data

so it was like:

I still dont have no update problem. The data is correct in my case!

[rkrkrk0987]

sorry for late reply, from my point of view without any knowledge of custom components, if you look at sensor.py

class EduPageNotificationSensor(CoordinatorEntity, SensorEntity):
    """Subject sensor entity for a specific student."""

    def __init__(self, coordinator, student_id, student_name, notifications):
        """Initialize the sensor."""
        super().__init__(coordinator)

        self._notifications = notifications
...

self._notifications is only assigned in __init__ function
and referencing in all functions... but during update __init__ function isn't called, just specific function eg: extra_state_attributes

for me, problem was solved by adding:

        notifications = self.coordinator.data.get("notifications", [])

like:

    @property
    def extra_state_attributes(self):
        """Return additional attributes."""
        notifications = self.coordinator.data.get("notifications", [])
        attributes = {}
        attributes = {
            "student": self.coordinator.data.get("student", {}),
            "unique_id": self._unique_id
            }

        for i, event in enumerate(notifications):
...
