Energy monitoring replenishment service

Abstract

Described implementations determine or monitor one or more parameters of an electrical circuit at a location to determine device usage at the location and utilize that information to determine when consumable inventory at the location is depleted and should be reordered. For example, when a device at the location is turned on, the device affects voltage that is introduced into the voltage signal at the location and detectable by, for example, a plug-in sensor. Different devices generate different patterns or signatures of voltage as they operate, thereby making the signatures unique, or almost unique, to different device types and/or different devices. Utilizing this information for devices that utilize consumable inventory, such as coffee pods, laundry detergent, dishwashing detergent, frozen dinners, popcorn, etc., it can be determined when the consumable inventory is depleted and should be reordered.
