Eaton's Home Heartbeat Home Awareness System network can report the status of up to 30 sensors in your home (sensors sold separately). The system can be customized so that you purchase only the sensors you want. The starter pack contains the components you need to get started, and you can add sensors as needed. Available sensors include: water, power, open/closed, garage, attention, reminder, and motion. Home Heartbeat applications include monitoring vacation homes and home of elderly parents, as well as monitoring your primary residence to maintain a safe environment. More information about the system can be found in the SmartHome sections of select Home Depot Stores, or on the Home Heartbeat web site at www.homeheartbeat.com.
