A method and apparatus are provided for controlling at least one entity of a remote source network from a local home network. The method is implemented by a relay module, termed a roaming relay module, designed so that when the module is executed by an appliance connected to the home network, the module communicates with a relay module, termed a source relay module, executed by an appliance of the source network and serves as communication relay in relation to the at least one entity. The method includes: a step of reception of a first request by the roaming relay module via a control interface, complying with a first protocol usable to control the entity from the source network; and a step of sending from the roaming relay module to the source relay module, a second request intended to be converted by the source relay module into at least one third request complying with the first protocol.
