Smart plugs can be useful for a variety of purposes. For example, you could use one to turn off a lamp or other appliance when you’re not home, or to turn on a space heater before you arrive to warm up a room. They can also be used to control power usage and reduce energy consumption by scheduling appliances to turn off automatically when not in use.

Some smart plugs also come with additional features such as monitoring energy usage, setting up routines, and integrating with other smart home devices. They can be a convenient and affordable way to make your home smarter and more energy-efficient.
