Abstract: A sensor-monitoring application can execute on a mobile device, tablet computer, or other portable device, and facilitates controlling sensors and navigating through sensor data either directly or via a sensor-managing service. A user can monitor feedback from a variety of sensors, such as a motion sensor, a temperature sensor, a door sensor, an electrical sensor. The user may interact with the application's user interface to control and synchronize various sensors, controllers, power switches wirelessly. The user can also control devices, such as by sending a command to a device via an electronic port, or by enabling, disabling, or adjusting a power output from a power outlet that provides power to a device (e.g., to a light fixture).
