How many times have you turned around on your way to work because you can't remember if you turned off your curling iron or hair straightener?
So, instead of sitting at work worried that you're going to get a call from the fire department, you can just go to the app and turn off everything that's plugged into the smart plug. It's a super-quick and easy solution that takes zero technical skills.
Many smart plugs can also be controlled by your smart home assistant, like Google Home and Amazon Alexa. So another benefit is you can easily heat up your hair tool while you're getting ready with just a command, as long as it is plugged into your smart plug.
