How to choose
No hub, app and voice control
All three plugs work without a hub: the Kasa uses the Kasa app, the EIGHTREE uses the Smart Life app with Bluetooth setup, and the KMC uses the KMC Smart app. All three answer Alexa and Google Assistant voice commands, and the EIGHTREE also supports SmartThings. Check that your phone runs a compatible app version and that your network runs 2.4GHz Wi-Fi, since all three require it.
Schedules and automation
Scheduling turns devices on and off without a touch. The Kasa sets timer and countdown schedules, and the EIGHTREE sets timers, countdowns, cycles and random schedules. The KMC automates by time, sunrise and sunset, weather and device status. Match the schedule type to your routine, such as lamps at night or a coffee maker in the morning.
Packs, ratings and warranty
Pack size sets how many outlets you cover: the Kasa and KMC come in 4-packs, while the EIGHTREE comes in a 1-pack. Ratings differ too: the Kasa and EIGHTREE are rated 1800 watts and the KMC is rated 1875 watts, all at 15A. Warranty differs as well: the Kasa carries a 2-year warranty and the KMC carries a lifetime warranty. Compare pack, rating and warranty against the outlets you plan to control.
