A method and system of monitoring a power outage of an endpoint device that does not have a backup power supply. The endpoint device comprises a meter, a power-line detector and a radio frequency interface module and is capable of monitoring a power-line, or any other source directly derived from the power-line, to determine when the endpoint device has lost line power. After a loss of line power the endpoint device transmits an outage signal or message to a reader using energy stored in a capacitor (or similar electronic element) therein. The reader then relays the outage message to a server having a software program that displays the outage message to the utility company.
