The door of Hanting Hotel keeps ringing.

I don't think it matters. The lock will sound a prompt. Probably have to slam the door. You can also see if the hinge is loose, causing the door to sink and the door piece to rub against the door frame.

Maybe it was not closed tightly, and the sensor on the door couldn't sense it, so you slammed the door. Generally, the bolt on the door is loose, and the back door can move back and forth after closing, so when the wind blows, the door can move back and forth and make a sound. The solution can be to stick felt or sponge double-sided tape on the door closing gap (that is, the door frame surface that the door touches when closing the door), and be careful not to be too thick to avoid closing the door.
