1. A method of selecting a hub comprising:
acquiring first radio wave strength information and second radio wave strength information, the first radio wave strength information being information related to radio wave strength of a sensor in wireless communication between a first hub and the sensor, and the second radio wave strength information being information related to radio wave strength of the sensor in wireless communication between a second hub and the sensor;
when the radio wave strength indicated by the first radio wave strength information and the radio wave strength indicated by the second radio wave strength information are a predetermined threshold or higher, and a connection order of a hub currently connected to the sensor among the first hub and the second hub is greater than a predetermined value, selecting another hub with an earlier order of connection to the sensor as the hub to be connected to the sensor from between the first hub and the second hub; and
when the radio wave strength indicated by the first radio wave strength information and the radio wave strength indicated by the second radio wave strength information are the predetermined threshold or higher, and the connection order of a hub currently connected to the sensor among the first hub and the second hub is equal to or less than the predetermined value, selecting the hub currently connected to the sensor as the hub to be connected to the sensor from between the first hub and the second hub.
