With ”Share Home”, devices are either added or removed from a specific Home profile and it is not necessary to share the same Home profile again. The new device information of the specific Home will be automatically synchronized to other shared users.

On the other hand, “Share Device” emphasizes single device sharing and is more flexible. It is used when you want to share only certain devices.

Note: If the app version of the admin account is running v4.0, but the app version of the shared account is older than v4.0, the device can only be shared using "Share Device" and not "Share Home".
