The TP-LINK HS100 smart plug is quite simply a power outlet that you can control from anywhere. Using your smartphone, you can turn devices on & off, set programs to turn them on & off at set times while you're away, or engage a "countdown timer" which powers the switch off after a set amount of time. Installation is simple -- just plug a device into your smart plug and connect to your wifi network. The HS100 is also compatible with Amazon Alexa, for voice control. Buy multiple plugs and get creative.
