A home automation system comprises a number of sub-systems for controlling various aspects of a house, such as a security sub-system, an HVAC sub-system, a lighting control sub-system, and an entertainment sub-system. The network comprises a host computer connected through a host interface to a plurality of nodes. The network is in a free form topology and employ asynchronous communication. The host computer polls each node on the network to determine system configuration and to perform a diagnostic check on the system. The messages that are transmitted between the nodes are comprised of a source address, a destination address that uniquely identifies the location of each piece of hardware on the system, a message type field, and a data length segment. Each hardware device has a mirror image software object in the host computer to which messages are directed. The user interfaces for the various sub-systems share a common interfacing method whereby use of the system is greatly simplified.

Home automation system

Disclosed is an AC power module for controlling the level of power to multiple electrical devices such as lights and household appliances according to control signals supplied from a processor unit. The apparatus utilizes low voltage control signals which are synchronous with the standard AC power supply to control several solid state relay which in turn regulate the AC power supplied to the devices. Each relay is optically isolated from the module. The module incorporates additional terminals through which back-up switching or control of additional relays (with different power ratings) may be provided. The module may be constructed on a single printed circuit board (PCB) to facilitate installation and removal. According to this embodiment, the PCB has pins which matably attach to a corresponding number of L-shaped tabs provided on a standard electrical box.
