A method and apparatus are provided for controlling at least one UPnP device of a remote network from a local network by a local relay module of the local network, which is able to communicate with at least one remote relay module of a remote network. The relay module obtains, via the remote relay module, at least one identifier of a UPnP device detected in the remote network by a UPnP monitoring point associated with this remote relay module, and records at least one identifier received in association with identification data of the remote relay module having provided this identifier. The relay module controls a UPnP device of the remote network by way of the monitoring point associated with the remote relay module, identified by the identification data recorded in association with an identifier of this UPnP device.
