1. An intelligent switchable device for selectively conducting electricity, said device comprising:
a switch for connecting a power line to a load, said switch having a control input; at least one sensor for producing a sensor signal indicative of a magnitude of; a transceiver for (i) transmitting data, including communications and (ii) receiving data, including instructions; non-volatile memory adapted for storing a program; a control circuit in communication with said transceiver, said sensor and said switch, said control circuit producing a command signal in response to (i) a sensor signal or (ii) instructions, said control circuit having a first mode of operation when the command signal is maintained in a conductive state, a second mode of operation when the sensor signal is above a threshold where said switch is rendered non-conductive, and a third mode of operation where the instructions command said switch to be non-conductive. |
