This power strip by TP-Link features six outlets and three USB ports. Unlike most smart power options, you can control each of the outlets separately. Instead of turning the entire power strip on, you can just turn on a lamp or your A/C. It’s also got an energy monitoring function. The strip can be controlled via the app or with voice assistants. So if you want to turn off a light after you've snuggled into bed, you can just say "Alexa, turn on outlet one."
