Embodiments include a device comprising an interface module for interfacing with proprietary legacy systems. The interface module comprises a data interface for interfacing with a processing component of the legacy system, where the processing component uses a proprietary protocol for processing data of the legacy system. The interface module includes a protocol module that comprises a protocol corresponding to the proprietary protocol of the legacy system, and the interface module uses the protocol to exchange data with the processing component. The interface module includes a communication device that communicates with a remote system via a wireless channel. The interface module controls communications that include passing commands from the remote system to the legacy system, and passing event data of the legacy system to the remote system.

Systems and methods for a security network integrating security system and network devices are disclosed. A system may comprise a gateway and first and second security panels, each located at a premises. The first and second security panels may be connected, via respective first and second wireless communication protocols, to respective first and second security system components. The first and second security panels may receive respective first and second security data from the respective first and second security system components. The gateway may be configured to receive, via the first and second wireless communication protocols, the respective first and second security data. The gateway may be configured to transmit at least one of the first security data and the second security data to a security server located external to the premises.

Systems, methods, and devices for routing data in a network are described. A user device may send a request for video data that has been captured by a premises device. A computing device at the premises may receive the request and determine a capability of the user device. Based on the capability of the user device, the computing device may select a protocol from a plurality of protocols with which the video data is to be transmitted to the user device. Based on determining that the video data cannot be transmitted via the computing device, the video data may be transmitted from the premises device to the user device via the determined protocol.

Methods and systems for reconfiguring an interface device are described. The interface device may comprise a housing, one or more processors disposed in the housing, a display, a network interface that enables communication with a security system, and a module connector. One or more of a plurality of modules may be removably coupled, via the module connector, with the interface device. The plurality of modules may enable the interface device to perform different functions. An example module, when coupled to the module connector, may enable communication between multiple networks.

A method for operating an appliance on a power grid operated by a utility is described. The method includes receiving, at a server associated with the utility, information indicating whether a person is present in a proximity of the appliance, determining, by the server, an operational state of the appliance based on whether the person is present in the proximity of the appliance, and transmitting to the appliance, via a communication link associated with the power grid, control information related to the operational state to control operation of the appliance. Related methods, devices and systems are described.

Disclosed is a system and method for power line control of electrical fans. The system generates a sinusoidal wave using a crystal oscillator. Control information is added to the sinusoidal wave by routing the wave through a phase inversion circuit a predetermined intervals according to a protocol. The resulting control signal is sent on a power line. The control signal is received using a crystal filter, decoded and converted to executable instructions for controlling a fan motor.

Embodiments include systems and methods comprising a gateway located at a premise forming at least one network on the premise that includes a plurality of premise devices. A sensor user interface (SUI) is coupled to the gateway and presented to a user via a remote device. The SUI includes at least one display element. The at least one display element includes a floor plan display that represents at least one floor of the premise. The floor plan display visually and separately indicates a location and a current state of each premise device of the plurality of premise devices.
