我认为大多数锁会提供选项 1。

对于 2：Schlage 锁说明了这一点 Built-in alarm technology senses potential security breaches at the lock, while the low battery indicator offers advanced warning for battery replacement

我还发现 August 有以下警报：

门被手动锁定或解锁

This alert notifies you when someone operates the August Smart Lock manually by hand or using a key.

门被特定用户锁定或解锁

This alert notifies you when a specified guest or owner operates the lock via Bluetooth. This includes unlocking the lock using the app

或自动解锁。

门半开（仅限第 3 代 Smart Lock 和 Smart Lock Pro）

This alert notifies you if the door is left open for a specific amount of time. Specify the amount of time in the lock settings.

门是自动上锁的

This alert notifies you when your August Smart Lock Auto-Locks. Auto-Lock can be set up in the lock settings page.

门被一键式键盘锁定（仅当 August Smart Keypad 与锁配对时）

This alert notifies you when the August Smart Lock is locked using the One-Touch Lock feature on the August Smart Keypad.

对于3：如果门无法连接Wifi，则无法与您联系。我能看到这种工作的唯一方法是让设备不断地敲门锁。如果在一定时间间隔后找不到，则发送警报。
