Smart plugs are no longer just about turning devices on and off remotely — some of the newest ones actually help you track how much electricity you’re using. The Kasa Smart Plug with Energy Monitoring is one such device, and it’s one of the most popular for good reason. It lets you monitor power consumption, set schedules, and control appliances via your smartphone. Below is a detailed review covering what it does well, where it falls short, and who would benefit most from using it.

Why Choose a Smart Plug with Energy Monitoring
Traditional smart plugs let you control devices remotely, but a plug with energy monitoring gives you an extra layer of insight and control. With this capability, you can:
-
See real-time and historical power usage, enabling you to identify energy-hungry devices.
-
Cut electricity costs by scheduling high-use appliances to run when energy is cheaper, or turning them off when not needed.
-
Increase safety and efficiency, since you can monitor always-on devices like space heaters, aquarium pumps, or chargers.
-
Make eco-friendly decisions, by understanding how much energy each device draws and reducing “phantom loads” (power used by electronics even when idle).
For many households, this kind of smart-plug is one of the most accessible ways to start making energy-conscious changes.
Key Features of the Kasa Smart Plug With Energy Monitoring
Here’s what makes the Kasa Smart Plug (with energy monitoring) stand out:
-
Energy Monitoring Capability: Tracks real-time and monthly energy consumption via the Kasa app. You can check how much power a device draws and how much it costs (if you input your electricity rate).
-
Remote Control: Turn devices on or off from anywhere using your smartphone — great for controlling lamps, fans, or chargers when you’re out.
-
Scheduling & Timers: Set schedules for appliances (e.g., have a heater turn off before bedtime, or lights come on at sunset).
-
Compact Design: The plug is small enough to avoid blocking the second outlet on a standard wall socket.
-
Wide Compatibility: Works with Alexa, Google Assistant, and IFTTT, so you can integrate it into your existing smart home setup.
-
Safe & Reliable: Includes overload protection and wide operating voltage (100-125V), making it safe for most household devices.
-
No Hub Required: Connects directly to your Wi-Fi (2.4 GHz), so you don’t need to buy an extra smart-home hub.
These features make the Kasa Smart Plug a solid pick for both basic automation and deeper energy insights.
Real-World Performance & Use Cases
Let’s talk about how this smart plug actually performs in daily life:
Monitoring Energy Use
Users report that after setting it up in the Kasa app, you can easily check real-time energy consumption for any connected device. For example, plugging in a space heater or an air conditioner allows you to track exact usage trends over weeks. That data helps you decide whether to replace an old appliance or shift its operation times.
Scheduling Power
Scheduling is easy via the app: you can set the plug to shut off at night, or to turn on just before you arrive home. For instance, many users automate holiday lights or a coffee maker. This helps cut wasted electricity (and reduces “always plugged in” usage).
Remote Control & Voice Integration
The plug responds quickly when you tap on/off in the app. It also works reliably with Alexa and Google Assistant, so you can use voice commands like: “Alexa, turn off the lamp” or “Hey Google, turn on the fan.” Very useful when you’re in bed or busy with other tasks.
Reliability & Safety
Kasa’s smart plug is known for being stable and well-built. The overload protection adds confidence when connecting higher-power devices. A few users mention that the plug does get warm when controlling “power hog” appliances, but not dangerously so — just something to monitor.
Pros, Cons & Who Should Use It
Pros
-
Real-time + historical energy usage data helps with cost-saving and efficiency.
-
Compact design fits most outlets without blocking others.
-
Scheduling + timers give you flexible automation.
-
Compatible with popular voice assistants and IFTTT.
-
No hub required — connects directly to Wi-Fi.
Cons
-
Requires 2.4 GHz Wi-Fi; no support for 5 GHz networks.
-
The initial data collection (for energy tracking) may take some time before you see meaningful monthly trends.
-
For very high-wattage appliances, the plug may heat up and approach its limits.
-
The app’s energy cost calculation is based on input rate, so you need to know your electricity price for accurate cost tracking.
Who Should Use It
-
People who want to reduce their electric bill by making data-driven decisions.
-
Homeowners who use always-on devices (like dehumidifiers, heaters, or chargers) and want to monitor their power draw.
-
Smart-home users looking for more than simple remote control — they want insight and automation.
-
Eco-conscious users who want to minimize “phantom power” consumption.
Final Verdict & Buying Tips
Final Verdict
The Kasa Smart Plug with Energy Monitoring offers a great balance between functionality and insight. It’s more than a remote switch — it’s a window into how your devices use energy. If used smartly, it can pay for itself in saved electricity, or at least provide clarity around where you’re wasting power.
For anyone serious about a smarter, more efficient home, this plug is an excellent starting point.
Buying Tips
-
Calculate your electricity rate: Knowing your $/kWh rate makes the energy-monitoring feature genuinely useful.
-
Pair with high-draw devices: Use it for devices that typically use a lot of power (heaters, pumps, chargers) to track and optimize their usage.
-
Use the schedule function: Automate times when devices run (or don’t) rather than manually turning them on/off.
-
Update firmware: Make sure the plug’s firmware is up to date via the Kasa app to get the latest features and security fixes.
-
Install in a 2.4 GHz network: If your Wi-Fi router has both 2.4 GHz and 5 GHz, be sure to connect the plug to the 2.4 GHz band for stability.
