Systems and methods to allow for a smart device
Smart switch devices, systems, and methods for modifying an existing electrical system to utilize the power state output of a physical switch as an indicator or signal for the operation of a smart home device or system or network of such devices to facilitate interoperability of physical switches with smart devices. The smart switch detects or determines the power state of a circuit and infers the corresponding state of a mechanical switch that operates the circuit. This information is then transmitted to associated smart devices, which may not be physically connected to the circuit controlled by the switch. When the mechanical switch is operated, it can control both electrically attached loads, such as a conventional light or appliance, and wirelessly control unconnected smart devices.
1. A smart switching system for operating conventional electrical devices in the same system as smart devices, the system comprising:
an electric circuit controlled by a mechanical switch;
an electric device adapted to connect to and receive power from said electric circuit via an electric power receptacle;
an electric smart device adapted to wirelessly receive operational commands; and
a smart switch comprising:
an electric power input adapted to receive electric power from said electric circuit;
a measurement device in electric communication with said electric power input and adapted to measure at least one circuit characteristic of said electric circuit; and
a wireless transceiver in electric communication with said measurement device, said wireless transceiver adapted to:
receive from said measurement device a reading of the power state of said electric circuit by said measurement device; and
wirelessly transmit to said electric smart device information about said power state of said electric circuit based on said reading;
wherein when said mechanical switch is operated to change the power state of said electric circuit, the power state of said electric device changes to correspond to said power state of electric circuit, and the power state of said electric smart device changes to correspond to said power state of said electric circuit.
