Kasa’s smart plugs are popular for a reason. They work reliably without a hub. The KP115 model adds a genuinely useful layer of intelligence with its built-in energy monitoring. This feature moves it from a simple remote switch to a tool for understanding your home’s energy habits.

You plug it in, connect via the Kasa app, and it just works. The compact design fits snugly in a standard outlet without blocking the second socket. Voice control with Alexa and Google Assistant is seamless for turning lamps or fans on and off. The real value is in the app’s energy tab. It shows real-time power draw in watts and calculates estimated costs over time. You can finally see how much energy that old basement freezer or your gaming PC actually consumes. At 15 amps and 120 volts, it handles most household appliances with confidence.

The monitoring provides clear insight, but it’s an estimate for cost calculations. You’ll need to input your local electricity rate for it to be accurate. For the price, it delivers a robust smart plug experience with data that can actually help you save money.
