A smart plug transforms even “dumb” devices into a part of your smart home network, giving you greater control and customizable options just by plugging the device in. Table lamps, the clothes iron, and even the coffee maker get an IQ upgrade with smart plugs. For the most features and best reliability, stick with smart plugs that connect to Wi-Fi either directly or using a bridge or dongle that plugs into your router.

Some smart plugs, like Amazon’s Echo Flex, have virtual assistant support built-in so you can speak directly to the smart plug instead of using an app to control it.

Wi-Fi connectivity allows you to remotely control devices plugged into smart plugs with your smartphone.

Voice control options allow you to use Alexa, Siri, or Google Assistant to control devices plugged into the smart plug unit (some models of the smart plug might require a bridge or dongle for this capability).

Track information about energy use and the cost of use for a device using the plugin in real-time.

Schedule smart plugs in your home or office to turn on or off at specific times — no more wondering if you left the coffee pot or clothes iron on. And you no longer need to worry about walking into a dark house or your house looking empty while you’re on vacation.

Smart plugs designed for outdoor use allow you to control (and schedule) items plugged in outdoors such as holiday lights and decorations.

Set smart plugs to restrict and prevent latent energy consumption by devices while they’re turned off.
