1. A communication system in which a first electronic device and a second electronic device, both connected to a single network, are associated with each other as being installed within a same space among a plurality of networks formed based on a wiring arrangement of a plurality of electronic devices in a plurality of spaces, the system comprising a relay device connecting a first network and a second network, the first network being the single network connecting the first electronic device and the second electronic device, the second network being a network different from the first network, wherein
in a state where communication between the first network and the second network is disconnected, the relay device:
transmits a first reply request, via the first network, to both the first electronic device and the second electronic device,
transmits first network identification information to the first electronic device upon receiving first electronic device identification information sent by the first electronic device to the relay device in response to the first reply request, and
transmits the first network identification information to the second electronic device upon receiving second electronic identification information sent by the second electronic device to the relay device in response to the first reply request, wherein

the first electronic device, upon receiving the first network identification information transmitted from the relay device, transmits a second reply request to the second electronic device, the second reply request including the received first network identification information, and
the second electronic device transmits the second electronic device identification information to the first electronic device upon confirming that the first network identification information included in the second reply request matches the first network identification information received from the relay device.
