Abstract

A device for controlling at least one electrical apparatus comprising a microprocessor wired to an RF transceiver, the microprocessor storing operating protocol commands as sent over a wireless network, the RF transceiver and microprocessor being configured in cooperation with software code residing in the microprocessor to receive real-time data as sourced from a network time source of the wireless network, and a clock circuit connected to the microprocessor and configured for storing the real-time data, whereby the device controls power to the electrical apparatus according to the operating protocol commands at real-time as obtained from the wireless network by which the operating protocol commands are sent and as kept by the clock circuit, thus eliminating the need for a separate GPS receiver in the device for receiving real-time data.
