Checklist

• I have enabled debug logging for my installation.
• This issue only contains 1 issue (if you have multiple issues, open one issue for each issue).
• This issue is not a duplicate issue of any previous issues..

Describe the issue

Every poll produces either a validation error or a timeout (see debug log examples). Because of the unhandled exceptions, the integration never updates the entities.

Notes / suspected cause:

• The API now returns numeric IDs for packageRecord / packageChanged, but PackageInfoResult still type-hints them as strings.
• The device_detail endpoint regularly exceeds the current timeout window.

Request:

• Update PackageInfoResult (and related models) to accept integers as well as strings.
• Consider increasing the default timeout/retry budget for device_detail.

Thank you very much for supporting this helpful integration!

Reproduction steps

1. Start Home Assistant with the Petkit integration
2. Wait for the scheduled background polling (occurs roughly every minute).
3. Observe the system log.

Hi @Tregaron1
Thank you for reporting
We check that point.

@rankjie it looks like the T6 is concerned.
Do you have the same on your side ?
