Smart plugs promise to turn any device smart, but their usefulness depends on the gadget you're plugging in—and whether it needs more than just power.

The TP-Link Tapo Matter-Certified Smart Plug Mini (P125M) sells for $19 (3-pack) with no app required. Cync Outdoor Smart Plug costs $19 with dual outlets, while Wyze offers a $29/2-pack option.

Matter compatibility allows cross-ecosystem control across TP-Link, Alexa, and Apple HomeKit.

Smart plugs work best for devices with manual on/off switches like lamps and outdoor lights.

They fail with devices requiring post-power activation—such as tea kettles, coffee machines, and TVs—which need additional signals beyond power cycling.

For devices without built-in smart features, smart plugs remain preferable over smart bulbs when controlling appliances like space heaters or fans.
