TP-Link Kasa Smart Wi-Fi Plug Slim EP25P4 Review

We’ve reviewed dozens of smart plugs over the years, but none are as versatile as the TP-Link Kasa Smart Wi-Fi Plug Slim With Energy Monitoring (EP25P4). This little plug works with nearly every smart home platform, is easy to install, and tells you how much power it provides to any devices you connect. The only slight drawback is that it is only available in a pack of four. But at $49.99 a set, it comes out to $12.50 per plug, which is perfectly reasonable for all the features you get. This makes the Kasa Smart Wi-Fi Plug the new winner in Editors’ Choice.

Compact Design, Excellent Third-Party Support

TP-Link Kasa Smart Wi-Fi Plug Slim EP25P4 is currently only available in packs of four, which means the price for a single ingredient is around $12.50. A bundle of four Emporia Smart Plugs ($29.99) or a bundle of two Wyze Plugs ($14.99) are cheaper on a per-plug basis, but neither offers as many features.

At 1.5 x 2.6 x 1.6 inches (HWD), the Kasa Slim is small enough to fit into a two-plug outlet without blocking access to other receptacles. This is a 15 amp plug rated to handle up to 1800 watts (120 volts).

The front of the plug has a three-prong port and the back has three prongs. The LED indicator and power button are on the right side. The LED flashes amber and blue during setup, quickly turns blue when connected to your network, solid blue when the connection is secured, during a factory reset, quickly flashes amber, turns solid when no network connection. The power button resets the Plug’s Wi-Fi connection when you hold it down for five seconds. There’s a 2.4GHz Wi-Fi radio under the hood to connect to your home network.

TP-Link Kasa Smart Wi-Fi Plug Slim EP25P4 works with several home automation platforms including Apple HomeKit, Amazon Alexa, Google Assistant, and Samsung SmartThings. It also works with IFTTT. Its channel of service helps you create integrations with a large number of third-party devices.

Features of Kasa Slim App

This component uses the same Kasa mobile app (available for Android and iOS) as all other Kasa devices, including the Kasa Smart Camera (KC400), Kasa Smart Wi-Fi Plug-in Dimmer (KP-405), and Kasa Smart Light Plug. Use (HS-103). It appears in the application in the Smart Plugs section. The plug also appears as an accessory in the Apple Home app. In this app, you can turn the plug on or off, add it to a kit, set it up in automation and viewer with other HomeKit devices. However, you still need to use the official Kasa app to view energy usage reports and configure them to work with other Kasa devices.

When you tap on the plug-in panel in the Kasa app, a screen with a large power button pops up. The button is green when plugged in and gray when turned off. The gear button in the upper right corner opens the Settings screen. Here, you can edit the plug name, toggle the LED, and add the plug to HomeKit Home.

Below the screen are the schedule, timer, space, and power buttons. Press the schedule button to create usage schedules based on the time of day or day of the week. The timer button allows you to set a specific time to turn the plug on or off. The Away button helps you set a schedule in which the plug is randomly turned on and off. The idea is that it gives the impression that someone is at home, even if they are not. Finally, click the power button to see your daily, weekly, and monthly power consumption and average uptime readings.

Back on the Devices screen, the Scenes button allows you to create scenes to control connecting devices and other Kasa devices at the touch of a button. You can also use the Smart Actions feature to create automated processes involving multiple Kasa devices. For example, you can set the plug to turn on or off when the Kasa Cam detects motion.

Fast Setup and Reliable Performance

Installing the TP-Link Kasa Smart Wi-Fi Plug Slim EP25P4 was quick and easy to test. After Installing the app and creating an account, tap the plus button in the upper-right corner of the devices screen. Click Add Device and then select HomeKit Smart Plug from the list of smart plugs. Plug in the device, click next, and check that the LED is blinking amber and blue. Click Add to Home Kit, scan the QR code on the side of the plug and wait a few seconds for the app to connect to it. To complete the installation and link the device to your account, simply specify a name and location for the socket.

The TP-Link Kasa Smart Wi-Fi Plug Slim EP25P4 performed better in my tests. Responded quickly to application commands and followed my usage schedule without fail. The power consumption readings were in line with the readings I received from my Kill-A-Watt meter. HomeKit Sense and Siri voice commands worked as intended, as did Alexa actions and voice commands. I had no problems with the Kasa Smart Action which I set to turn on the plug when the Kasa Smart Action detected motion.
