What is the reason why the room light in the smart hotel can't be turned off automatically after picking up the card?

System failure.

Usually, guests who stay in a hotel unplug the card of this hotel, and then the lights in this room will be turned off. If there is no phenomenon that it can't be closed, it means that there may be some problems with this system. You can ask the front desk clerk of the hotel to reflect the situation.
