Our 10 Best Energy Usage Monitors of 2022

It’s not necessary to wait until you receive the electric bill to figure out how much energy you use. Your bill only shows your total energy usage for the period and your annual total, not how and where you can reduce it.

Energy monitors provide real-time information that provides more precise data and usage trends that can help you use less energy. An energy monitor can detect inefficiencies, integrate with smart-home tools, and even estimate solar output.

Stop wondering why your electricity bill is so high, and use the best energy usage monitor to understand where the electricity is spent.

Before You Buy a Home Energy Monitor

It is important to determine the type of home energy monitor that best meets the needs of the user before purchasing it. Energy-efficient homeowners may only need information about one or two appliances, while energy-conscious homeowners may want a more comprehensive option.

Outlet Monitoring

A smart plug outlet is the easiest way to measure the energy use of an individual outlet. They are best suited to track a few “energy hog” appliances rather than all the appliances in your home. When connected to the home’s Wi-Fi, the smart plug shows how much energy the device consumes. The plug plug plugs into a wall socket, and the appliance plugs into the smart outlet.

Smart plug monitors, however, have limitations. They are not compatible with large appliances, such as laundry machines; rather, they are compatible with smaller appliances, such as blenders and hair straighteners.

Whole-House Power Monitors

An energy monitor that connects to the electrical panel or meter of your home provides a detailed account of your home’s energy usage. Based on the connection to an individual circuit of each appliance, the energy monitor tracks its performance and power consumption.

When connected to Wi-Fi, home energy monitors provide real-time details on energy use and cost directly to a phone or computer dashboard.

What to Consider When Choosing the best energy usage monitor

Each household’s best energy usage monitor provides information that is most useful to them. A monitor might include energy details on a home’s solar system or appliance-specific information, enable voice commands, provide easy installation, or have an easy-to-use app. Here are some important factors to consider when choosing the right home energy monitor.

Solar Monitoring

Using a solar inverter, energy from the sun can be transformed into alternating current (AC) electricity to lower a household’s electric bill. These devices track both usage and generation and can identify peak solar times.

Energy monitors connect to a home’s utility meter to track energy inputs and outputs. Some devices show side-by-side comparisons of energy inputs and outputs and notify homeowners when energy consumption or production changes.

Appliance Recognition

Energy monitoring systems for the entire house plug into individual circuits on the electrical panel. Some of these systems provide circuit-specific information, but smarter ones learn the electrical signature of each appliance and track them individually. With appliance recognition, you’ll be able to pinpoint how much energy your appliances use, and some can even send alerts if the refrigerator door is open.

Energy monitors can make specific recommendations to reduce energy usage by recognizing appliances. Notifications can be sent to unplug a blow dryer, adjust a programmable thermostat, or advise which appliances need to be upgraded. It is possible to reduce energy consumption by tracking the energy consumption of each appliance rather than all the appliances connected to a circuit.

Real-Time Cost Tracking

The electricity bill is a record of how much energy a home uses weeks after the usage occurs. Tracking how energy is used in real time allows the home’s occupants to take action in the moment to minimize energy waste. Using an energy monitor, families can see how much energy they use and what it costs them in terms of kilowatt-hours and dollars.

It is possible to uncover behavior and patterns that contribute to energy overuse through tracking in real time and receiving in-the-moment notifications. This information can help identify and correct the sources of wasted electricity. Real-time cost tracking makes it possible to identify “vampire” appliances, which draw electricity while on standby, and energy-consuming appliances, so they can be unplugged, replaced, or repurposed.

Smart-Home Compatibility

There are smart-home energy monitors that fit into the electrical panel and communicate wirelessly with other smart-home devices. These monitors are equipped with WiFi and Bluetooth capabilities, so they can communicate and interact with other smart-home appliances.

In addition to providing a detailed description of data, an energy monitor can also be linked to a smart thermostat or plug-in to enable users to operate appliances remotely. Using these models, you can monitor your home’s energy use up to the minute, identify patterns, calculate operating costs, and more.

Mobile Apps and Notifications

In most cases, home energy monitors connect home energy information to a smartphone to provide instant updates about energy usage. Once installed, they eliminate the need for reading meters and visiting the electrical panel. With these apps, you can easily understand a home’s energy usage and identify areas that need improvement, since they are visual and user-friendly.

There are many home energy monitors that come with an app that you can download with a dashboard to track usage, trends, and more. In some cases, the app can review and initiate action items from remote locations. With the app, you can set up notifications to learn about critical use events, peak usage times, energy waste, and other analytics.

Voice Control

Alexa and Google Assistant can be used with some whole-home and smart-plug energy tracking outlets. Hands-free capabilities are a major benefit for the elderly, those with mobility issues, or those in places where outlets are difficult to reach when syncable to these digital assistants.

Smart systems enable use of voice commands to activate energy-saving tasks, such as turning off appliances with a verbal command instead of logging into an app dashboard.

Programs and Timers

Personalized programs can save energy in the home. Each home energy monitor has a program that manages technology and energy. Some examples include:

  • A smart system can be programmed so that when an alarm sounds, the house heats up, the lights come on, and the coffee maker starts automatically.
  • A user can program an appliance to turn off or go into energy-saving mode when they leave the house.
  • If goal setting is important, the user can find a home energy monitor to stay on track to reach those energy-saving goals. In addition, the user can set alerts to remind them to turn off specific devices.

It is possible to program timers so outlets will turn off after a certain period of time, preventing vampire appliances from drawing electricity.


Monitors that measure energy consumption from individual appliances are usually plug-in monitors that are plugged into a wall socket.

In order to install a whole-home energy monitor inside an electrical panel or on a wall, it is more complicated. In most cases, a home energy monitor includes sensors that clip on individual circuits and a small unit that analyzes the data. The number of circuits to be monitored can influence the choice of a home energy monitor.

If you’re unsure about installation, find a professional to handle it. After the hardware is installed, connect the device to Wi-Fi, and it should be up and running in just a few minutes.
