The real difference
Smart plugs make one outlet smarter. Smart switches make one circuit smarter. That sounds obvious, but it answers almost every buying question.
A smart plug is reversible. A smart switch is infrastructure. The plug is easier to test. The switch is better when everyone in the house expects the wall control to work normally.

Buy the plug when
You are automating a lamp, fan, coffee setup, charger, holiday light, or small appliance. You rent. You want to experiment. You want to move the automation later. You do not want to open a switch box.
Buy the switch when
The light is hardwired. The room has multiple people using it. You want voice control without disabling the wall switch. You want porch or entry lighting to run on a schedule while still behaving like a normal switch.
Frequently asked questions
Should renters use smart plugs or smart switches?
Smart plugs. They are removable, cheap, and do not require electrical work. Smart switches are usually a homeowner upgrade.
Do smart switches need a neutral wire?
Many do, including the Kasa HS200. Check the existing switch box before buying. If you do not have a neutral wire, choose a no-neutral switch or use smart bulbs or plugs instead.
Can a smart plug control ceiling lights?
Not unless the light is plugged into an outlet. Hardwired ceiling lights need a smart switch, smart bulb, or smart relay.
