How does ComEd know a customer is being billed with usage data from the correct meter?
If the meter is accessible, you will not need to be home. ComEd meter readers will leave door-hangers with information to let you know they’ve been to your residence. If the meter is inaccessible, after two attempts ComEd will contact you to schedule an appointment. The smart meter network is built around device authentication. Each smart meter is given a set of three credentials at the time of manufacture, which compose its unique cyber identity. These credentials never change throughout the lifetime of the device and are used to authenticate the device and its data at the time of billing, making sure a customer is being billed from the correct meter.
