Abstract: The invention provides a method for coupling a smart home device to a mobile terminal, comprising the following features: the smart home device (10, 20, 30) is connected to a server (40) via a source NAT router (14, 24, 34); the mobile terminal (12, 22, 32) is connected to the server (40) via the same source NAT router (14, 24, 34); the server (40) compares a public network address of the smart home device (10, 20, 30) with a public network address of the mobile terminal (12, 22, 32); and where the public network addresses match, the server (40) forwards an identification feature of the smart home device (10, 20, 30) to the mobile terminal (12, 22, 32). The invention also provides a corresponding server, a corresponding computer program and a corresponding storage medium.
