What this smart plug does

The WUQ 4456 plugs between a wall outlet and any appliance to measure real-time electricity consumption. It displays power usage on an LCD screen and automatically converts the data into cost estimates by day, week, month or year. Built-in memory retains all measurements even when the unit is unplugged.

How it performs over time

The monitor tracks cumulative energy use continuously rather than only sampling a momentary load. Its Cycles Mode steps through stored readings so you can review long-term trends without losing data. This makes it suitable for checking appliances that cycle on and off, such as refrigerators or air conditioners, across full billing periods.

The spec that decides fit

This unit uses a proprietary plug-in protocol rather than Wi-Fi, Zigbee or Bluetooth, so it cannot connect to a smart-home hub or phone app. Buyers who need remote logging, voice control or automated scheduling should choose a networked smart plug instead.
