Kasa EP25 Smart Plug Energy Monitor
The Kasa EP25 became my default recommendation. The TP Link app is responsive, the schedules actually fire on time, and the energy monitoring shows historical usage in clean graphs. Setup took under two minutes per plug. After six months of daily use I have not had a single connectivity issue, which is more than I can say for some pricier alternatives.
I plugged five energy monitoring smart plugs into my appliances for a month to find which ones gave me usable data and reliable scheduling.
I got curious about phantom power draw in my house after my electric bill jumped one winter, so I bought five energy monitoring smart plugs and put them on different devices around the house. I learned which appliances were eating power overnight, which ones were fine, and which plugs gave me useful insights versus which ones just turned the lamp on and off.
I compared each plug on the same set of devices, including my entertainment center, a space heater, a desktop computer, and a coffee maker. I cared about energy reporting accuracy, app reliability, and whether scheduling actually worked when I was on vacation.

Kasa EP25 Smart Plug Energy Monitor
The Kasa EP25 became my default recommendation. The TP Link app is responsive, the schedules actually fire on time, and the energy monitoring shows historical usage in clean graphs. Setup took under two minutes per plug. After six months of daily use I have not had a single connectivity issue, which is more than I can say for some pricier alternatives.
Wemo WSP080 Smart Plug
The Wemo is the smart plug to buy if you live in HomeKit. Setup with the Home app is the smoothest of the group, and the plug shows up alongside the rest of my home automations without needing a separate app. Energy monitoring data flows into HomeKit and shows up in the Eve app for richer historical tracking.
Amazon Smart Plug Energy Monitor
If you are deep into Alexa, the Amazon Smart Plug pairs in literally one tap. The energy reporting added in recent firmware is a welcome upgrade and works well in the Alexa app. The trade off is the plug is bigger than the others and blocks the adjacent outlet on most receptacles.
Eve Energy Smart Plug
The Eve Energy is the technical winner of the group. It supports Thread, which means it works with a Thread border router for fast local control and falls back to Bluetooth if Wi Fi drops. The energy reporting is the most detailed of any plug I compared, with hourly granularity and exportable CSV data. The premium price reflects the build.
Meross Smart Plug Energy Monitor
For around 11 dollars per plug in a multi pack, the Meross is the easiest way to deploy energy monitoring across a house without breaking the budget. The app is functional rather than beautiful, and the energy data is accurate. The plugs are physically compact enough to fit two on a standard duplex outlet.
My Setup
I put Kasa EP25 plugs on the entertainment center, the desktop computer, and the coffee maker. The Eve Energy lives on a space heater because the energy data is so detailed I can see exactly when it cycles. The Wemo handles the lamp by my front door on a sunset schedule, and the Amazon plug runs the holiday lights every December.
Frequently asked
Better than I expected. I cross checked three plugs against a Kill A Watt meter and the smart plugs were within 2 percent over a 24 hour reading. Good enough to spot phantom loads and compare appliance usage.
Most do. The plugs I picked all support Alexa, Google, and SmartThings. Apple HomeKit support is rarer. If you live in the Apple ecosystem, double check before buying.
