- Voice and scene control One command to Alexa Google Assistant or Siri turns off multiple outlets together
- Safety shut off If current spikes advanced plugs cut power to protect both device and socket
Quick win Turning off one game console or cable box that idles at 10 watts saves about 87 kilowatt hours each year which equals 15 to 25 US dollars at average utility rates
