What communication method does the hotel intelligent door lock usually use?

Generally, short-range wireless communication technology is adopted. Because most of these door locks are powered by dry batteries, ZigBee is widely used, and its low power consumption characteristics can better meet the needs. For example, the dormant current of modules such as ZM5 168 can be as low as 100nA, and the routability and other functions also increase the control range of ZigBee. When the electronic lock is opened or closed, wireless information can be sent to the remote monitoring platform in time.
