Abstract: Tasks associated with an add-on software program can be seamlessly incorporated into core software tasks. A directory associated with the add-on is interrogated for similar tasks when the corresponding task is actuated in the core software program. The directory names are copied over into an array associated with the core software program and a link is created between those names in the array and the directory from which they were taken. Thus, a drop-down menu may be implemented in a task or navigation bar in the core software program which allows the corresponding tasks in the add-on to be seamlessly incorporated into the operation of the core software.

Abstract: The present invention relates to a wireless home automation system having a controller for controlling a broad variety of functions via two ways communication with a plurality of devices. More specifically, the invention relates to an improved and flexible way of routing signals from a controller to a device which includes the building of various tables such as routing tables. The improved and flexible way of routing allows the user to reach any device within the network with a high reliability. According to the invention, a processing unit of a controller is adapted to instruct a first device to discover other devices within its range by transmitting a signal comprising a device table holding device identifiers of devices controlled by the controller. The devices in the system are adapted to, upon instruction, perform a discovery of other devices within its range by transmitting discovery signals addressed to each device in the device table received from the controller. The devices save the identifiers of the device which acknowledges the reception of the discovery signals in a list indicating which devices of the device table it can reach and which it can not reach. The controller can at any time collect the saved list from a device to build a routing table.
