Can I still receive the usage information after deleting the smart home application?

No. Delete the application from the smart home on the device. If the device Id of this device is pushed, APNS will push it to the device again, but the device will not receive the push, because deleting the application from the device will not inform the mobile push, so this device still exists in the mobile push device library, APNS will return the push failure message and inform the device of the token error, and the mobile push will receive this error message. The deviceToken will be deleted, and the deviceId will be pushed later, so it will not be pushed to the device again, and the usage information will not be received, so it will not. APP is the abbreviation of English Application, which means application, and refers to the third-party application of smart phones.
