A motor leakage current detector and/or a heat compensating circuit, devices using same and related methods are disclosed herein. Included are a uniquely wired current transformer to allow for polarity agnostic leakage current detection, a leakage current detector using same and having a notifier to alert a user. In other forms, an accessory power cord and power strip are disclosed capable of detecting early motor failure conditions. In still other forms, other machinery failure early warning systems are disclosed as are numerous motor operated devices using same including without limitation pumps.

Motor leakage current detector, devices using same and related methods

Methods, devices and monitoring systems are described that include a hub in communication with sensors that aggregate activities in an enclosure, such as a building. The hub identifies when those activities are occurring more or less often than expected and classifies the activity to piece together and learn the user's or individual's daily activity. Additional satellite devices may be added that increase the range and capacity of the sensors for collecting more information and activity within the building. In this manner, the monitoring systems use a redundant array of sensors to consistently monitor activities occurring in or around a building to create a trail and heatmap of events and activities that the monitoring system's hub classifies, verifies with other sensors, learns, and then correctly processes.

Non-intrusive monitoring system

A smart plug system is disclosed. The smart plug system includes a power plug configured to receive an alternating current power signal from shore power, a power receptacle configured to receive a plug having a plug blade, and a plug detection switch configured to detect receipt of the plug blade in the power receptacle. A rectifier circuit is included to rectify the alternating current power signal received at the power plug when the plug detection switch is actuated by receipt of the plug blade. The plug detection switch is further configured to prevent rectification of the alternating current power signal by the rectifier circuit when the plug blade is removed from the power receptacle. A logic level converter is included to receive the rectified power signal to convert the rectified power signal to a logic level signal.
