A communication system includes a HAVi-based in-home networkand a remote deviceoperative to communicate with an intermediate deviceof the in-home network via Internet. The remote device loads a HAVi applet (Havlet)for controlling at least one of the in-home devices using HAVi. The remote device also loads an HAVi API (HJA) emulatorwhich emulates HJA. The HJA emulator provides an interface for the Havlet and communicates with a modulein the intermediate device. The intermediate device includes the actual HJAwhich provides the actual interface functionality for the HAVi functions used by the Havlet. The interface functionality is provided by controlling the intermediate device and/or communicating with other in-home device(s) according to application messages of the in-home application protocol. The intermediate device loads the module for enabling communication between the HJA emulator in the remote device and HJA loaded in the intermediate device, giving a substantially transparent communication path between the portable application program in the remote device and the HJA in the intermediate device.
