A smart plug is a device that allows you to control electrical appliances remotely using a smartphone or tablet. By connecting a standard appliance to a smart plug, you can turn it on or off, set schedules, and monitor energy usage through a dedicated app. This technology enhances convenience and can help save energy. Smart plugs often work with voice assistants like Amazon Alexa or Google Assistant, enabling hands-free control. They are easy to install; simply plug them into an outlet and connect your device. Smart plugs are compatible with various appliances, making them a versatile addition to any smart home setup.
