A meter unit, co-located to an electric meter, and a building unit, co-located with an energy management system, cooperate to deliver electric meter relay pulses from the electric meter to an energy management system via a wireless link. Meter relay pulses are input to the meter unit from the electric meter, relay states and pulse counts are transmitted to the building unit, and the states of the relays and pulses are regenerated by the building unit as outputs to the energy management system. The pulses output from the building unit perform as though they were created by the meter originally, but without the traditional wired connection. The system provides for error correction should a pulse count transmission be lost, as well as repeating of an end-of-interval pulse so that the energy management system may synchronize its data collection and operation to the measurements from the meter.
