Pick up one of those fire-prone chinese hoverboard scooter things.
Innocently plug it in into the Managed Power Strip that can be powered on via web interface. Make sure the power strip is off and this is all in the garage. Next to your gas can for the lawn mower. And your paint stripper. And that gallon of moonshine pappy brought over. Which is right under the shelf with those fireworks you picked up for you next party. And the flares for your flaregun.
While away on vacation, vpn back through your home network and start a flame war (HA!) until someone decides to get your IP (your Home) and hacks you manages to cause as much damage to your home network as possible and turning on the power strip while he (or she) is at it.
Power strip is on.
Hover Board is charging.
Then Over charging.
Then catching on fire.
And a beautiful bonfire is happening.
