Sensing system and sensing method

A sensing system comprising:

• a detection data storage medium configured to store detection data detected by a home appliance installed in a building to be sensed, a detection time of the detection data, and appliance identification information for identifying the home appliance in association with each other;
• a determination criteria storage medium configured to store determination criteria for determining presence or absence of a person in the building based on the detection data;
• and
• determination processing circuitry that, when receiving a predetermined specific communication, is configured to determine presence or absence of a person in the building based on the detection data stored by the detection data storage medium, which is the detection data in a determination period based on a reception time at which the specific communication is received, and the determination criteria stored by the determination criteria storage medium, wherein
• the determination processing circuitry is configured to determine presence or absence of a person in the building when receiving, as the specific communication, a communication that occurs when a user manually or automatically initializes a network setting after power supply to the home appliance is interrupted, and that is an initial communication for the home appliance to establish a communication with another device, from the home appliance.

• when data is missing in the detection data in the determination period, the determination processing circuitry is configured to complement the detection data in the determination period with the detection data from another similar building based on a similarity with the building to be sensed.
