Abstract: A management system includes a management host device and at least one mobile device, and the management host device executes a management method. The management host device executes a normal mode, a temporary mode, and an unmanned mode. In the normal mode, the management host device broadcasts a first connection signal. In the temporary mode, the management host device broadcasts a second connection signal. When the mobile device receives the second connection signal, the mobile device transmits a resume command to the management host device. When the management host device receives the resume command, the management host device executes the normal mode instead. When the management host device does not receive the resume command, the management host device executes the unmanned mode instead. Therefore, the management host device can automatically control at least one target device to be turned on or off, thereby avoiding unnecessary power waste or safety concerns.
