Apparatus and method for managing IoT devices

A method of managing a device, comprising steps of:

• deriving a condition for check timing for the device;
• transmitting, to the device, a notification setting message to request the device to provide information on the check timing based on the condition;
• transmitting, to a manager apparatus, an expiration warning message providing notification of estimated check timing when the expiration warning message comprising the check timing estimated by the device based on the condition is received from the device;
• and
• transmitting, to the manager apparatus, an expiration alarm message providing notification of check timing satisfying the condition by the device when the expiration alarm message comprising the check timing is received from the device.

A method of managing a device, comprising steps of:

• receiving sensor data from a plurality of devices;
• embedding states of the plurality of devices in a vector space using the sensor data of the plurality of devices and parameters for the plurality of devices;
• deriving a target check device that needs to be checked, among the plurality of devices, based on similarity in the vector space;
• and
• transmitting, to the derived target check device, a check request message that enables the derived target check device to perform a self-check.
