What do we do when the product is powered off?

When the lock power is less than 10%, the lock and APP will remind you to replace the battery. If the lock is powered off as a result of not replacing the battery in time, the mobile power supply can be connected via a type-c port at the bottom of the outer panel. Alternatively, you can use the emergency keys.

Is Finger Vein and Palm Vein unlocking safe?


It is safe. The palm vein algorithm verifies the internal biological characteristics of the human body, which cannot be stolen by remote and non-inductive collection, and has high security.

When I return to the live screen page from another page, why is it sometimes disconnected?


When you jump to another pages, we strategically pause viewing live footage to reduce unneccessary camera power comsumption. After returning, if you want to continue viewing the live screen, you can "click to retry" to continue viewing.




Why sometimes the power in the MiHome consumables is inconsistent with the power of the door lock plug-in?


This problem usually occurs after the large battery is pulled out. At this time, due to the suspension of peephole's work, it is unable to report the battery level through WiFi, and Mijia does not support reporting this event through the gateway for the time being, so this problem occurs.


Solution: Enter the door lock plug-in to check power.
