Best Smart Plugs: How They Work and 7 Top Models to Save Energy 2026

Smart plugs are affordable devices that let you control any appliance remotely and monitor its energy use, helping you save on your electricity bill. In this guide, we explain how they work and recommend seven top models, including the Tapo P115.

What Is a Smart Plug and How Does It Work?

A smart plug is a small adapter that fits into a standard wall outlet and connects to your Wi-Fi network. Once paired with a mobile app, you can turn connected devices on or off from anywhere, set schedules, and even track energy consumption in real time.

Most smart plugs support voice control via Amazon Alexa or Google Assistant, and many offer advanced features like away mode, which turns devices on and off randomly to simulate occupancy while you're away.

Why Use a Smart Plug to Save Energy?

Many households waste energy because devices are left on standby or run unnecessarily. Smart plugs give you granular control, allowing you to eliminate phantom loads and optimize usage.

With energy monitoring models, you can identify which appliances consume the most power and adjust your habits accordingly. For example, you might discover that your space heater is driving up your bill and decide to use it more sparingly.

Key Features to Consider Before Buying

• Energy monitoring: Track real-time and historical consumption to make informed decisions.
• Power rating: Ensure the plug can handle the load (e.g., 16A/3680W for high-power appliances).
• Size and design: Compact models won't block adjacent outlets, especially in power strips.
• App and voice control: Compatibility with Alexa, Google Assistant, and a reliable app.
• Scheduling and timers: Automate devices to run only when needed.
