Smart plugs are the easiest entry point into home automation — plug one in, connect it to Wi-Fi, and suddenly any dumb device becomes voice-controllable. For under $25 each, you can automate lamps, fans, coffee makers, and holiday lights without rewiring anything. Here are the best options we've tested.
Best overall — reliable app, energy monitoring, compact design
The Kasa KP115 is the gold standard for budget smart plugs. TP-Link's Kasa app is one of the most stable and responsive smart home apps available — no random disconnections, no phantom schedules. The built-in energy monitoring tracks real-time and historical power consumption, and the compact design leaves the second outlet free. Works with Alexa, Google Home, and SmartThings.
Best for Alexa homes — zero-setup integration
If your smart home runs on Alexa, this plug is friction-free. Plug it in, open the Alexa app, and it's connected in under 30 seconds — no separate app needed. The physical button is a nice touch when you want manual control. The one downside: no energy monitoring, and it only works with Alexa (no Google Home).
Best value — great features at a lower price
Govee's smart plug offers the same core features as TP-Link at a slightly lower price point. The Govee Home app supports scheduling, timers, and away mode. It works with Alexa and Google Assistant. The plug is compact and doesn't block adjacent outlets. Govee also makes smart lights and thermometers, so the app unifies multiple device types.
Best bulk buy — 4 plugs for $20
At roughly $5 per plug, this 4-pack is unbeatable for outfitting multiple rooms. The KMC app handles scheduling and timers, and works with Alexa and Google Assistant. Build quality isn't as premium as TP-Link, and the app can feel slower, but for basic on/off automation these get the job done cheaply.
Yes, almost all budget smart plugs under $25 support both Amazon Alexa and Google Assistant. Some also work with Apple HomeKit (look for Matter-compatible plugs). Voice control setup is typically quick — just enable the skill in your Alexa or Google Home app.
Most budget smart plugs are rated for 10–15 amps (about 1200–1800 watts). Small appliances like lamps, fans, and coffee makers are fine. Space heaters and air conditioners draw too much power — use a heavy-duty smart plug rated for 20+ amps for those.
Most budget smart plugs lose remote control and scheduling when Wi-Fi drops. However, the physical button on the plug still works, and any schedules already saved to the plug will continue running. For Wi-Fi-free automation, consider Zigbee or Z-Wave plugs with a hub.
Most smart plug apps support 50–100+ devices. TP-Link Kasa and Govee apps handle large networks well. The real limit is your Wi-Fi router — each plug is one device on your network. Most home routers handle 30–50 smart home devices without issues.
