Quick reference

What it is
A compact module that makes a standard outlet switchable from an app, a schedule, or a voice assistant.
Typical load
Most household models are rated near 15A / 1800W. Always stay under the printed rating.
Network
Many plugs use 2.4 GHz Wi-Fi. Matter models can join Alexa, Google Home, and Apple Home more cleanly.
Best uses
Lamps, fans, chargers, holiday lights, and devices that waste power while idle.
Avoid
Space heaters, irons, and other high-heat appliances unless the plug is explicitly rated and listed for that load.
