Abstract: The disclosure includes a use-tracking vessel that comprises a vessel body that defines a vessel cavity via sidewalls, a level sensor to sense an amount of liquid present within the vessel cavity, and a communication device to communicate data. The vessel can obtain and store data indicating a volume of fluid present in the vessel cavity over time. The disclosure also includes a method of vessel use tracking that comprises obtaining data from a plurality of vessels indicating a volume of fluid present in respective vessel cavities of the vessels over time and identifying one or more use-events associated with the respective vessels based at least in part on the received data indicating a volume of fluid present in the respective vessel cavities of the vessels over time.
