Why does my Huawei connection send no data?

Huawei connecting without data almost always traces to a permission or toggle on the user's side, or missing key scopes.

Checklist:

• During the link flow, permissions are deselected by default, so the user must tap select all.

• Enable the Health Service Kit toggle under Me > Privacy Management > Health service kit. It is often off by default and is a common cause of 401/no-data.

• Confirm cloud sync is on (Me > Settings > Data sharing & Privacy).

• Confirm they linked with the same Huawei ID the watch is paired to, with the watch paired and showing recent activity. Non-Huawei phones still need Huawei Health installed with cloud sync on.

For data before authentication, your dev team must add historical-data permissions to your Huawei keys in the Huawei console and re-submit the app for verification. Without them, you only get data after auth.

A screen recording of the full link flow helps confirm the permission step.
