Whenever Homeassistant container is being updated (e.g. new HA version), the entity duration get lost and is no longer provided.
Restarting the Petkit integration fixes it always.

Hi @bondskin
Thanks for reporting i will check what the problem

[DalfDev]

Hi, Same issue here I will create a PR

[DalfDev]

Opened a fix for this: #275

Root cause: pet_last_use_duration (this issue) and pet_last_weight_measurement are siblings under the Pet: [...] list in sensor.py, both declared with restore_state=True. Both go through PetKitDescSensorBase.is_supported() in entity.py, which calls the description's value() lambda before the entity is created. If the coordinator value is momentarily None/falsy right when platforms are set up (e.g. right after a container/HA restart), the entity is never instantiated for that session at all — so RestoreSensor never gets a chance to restore the last known value, and the entity silently disappears until the integration is reloaded.

The PR skips the value-based existence check for restore_state=True descriptions so they're always created and can rely on RestoreSensor as intended.

@Jezza34000 would you mind taking a look when you get a chance?
