Abstract: A smart device for a household consumable includes at least one load sensor configured to measure a current load of a household consumable being supported by the smart device and a processor configured to compare the current load to a previously measured load to determine whether to increment one of a plurality of consumption event counters. The processor is configured to periodically transmit data located in the plurality of consumption event counters.

Abstract: Systems and methods disclosed herein include receiving first data sent over a first wireless communication channel from a first inertial sensor positioned in or on a first shoe worn by a user, wherein the first data are generated when the user performs a fundamental movement; identifying a first phase of the fundamental movement by finding a match, within a first tolerance, between a portion of the first data and data characteristic of the first phase; comparing a feature from the portion of the first data to a corresponding feature from a pre-established signature associated with the first phase; and when the comparison yields a result that falls outside a pre-established threshold range, displaying an indication that the feature from the portion of the first data is uncharacteristic.
