摘要:
Methods, systems, and devices for detecting when an end-device is physically disconnected from a commodity delivery network. One method includes determining an impedance of a power input of the end-device after the end-device experiences a power interruption, generating a message including data regarding the impedance, transmitting the message to a computer-implemented back office over at least one communication network, and automatically setting a status of the end-device to a physically-disconnected status when the data regarding the impedance indicates the impedance is greater than a threshold.
