The SmartHome system is a prototype for a smart home where the user can add any number of sensors and create rules around them to interact with them. Utilizing an internally developed system called sensor hive, SmartHome enabled the use of Phidgets sensors to monitor a variety of household devices. Once the devices are connected, a web interface allows the user to see when the devices are on or off, as well as the history of use of those devices [9]. This system, however, had a relatively simple rule system and the sensor hive could only interface with Phidgets sensors. These two aspects greatly limited the benefits of the system overall, but the web user interface that was used in SmartHome is a remarkably simple one that still accomplishes the goal of getting the information to the user in a way that is useful and intuitive. Therefore, we took a great deal of inspiration from the design of their web interface for visualizing the sensor data. To overcome the limitation of sensor hive, we adopted the GSN server for connecting to a variety of sensors.
