With energy costs on the rise, using a home energy monitor to pinpoint how and where you use electricity is a smart way to lower your bill. Rather than waiting for a monthly statement that only shows your home’s total energy consumption, getting real-time usage data can help you increase energy efficiency and save money.

A home energy monitor can catch appliance inefficiencies, sync with smart-home tools, and even calculate solar system energy production. They use technology to monitor energy use as it occurs and break down the energy spent in kilowatts and even dollars and cents.

To determine which home energy monitors would be most useful in your home, we spoke with Mike Naughton, the founder and CEO of Integrity Energy, a commercial energy company in Ohio. Based on his insights and our independent research, we chose the Sense Home Energy Monitor as our top pick for its ease of use and comprehensive feature set. If you’re ready to stop wondering why your electricity bill is so high, one of the best home energy monitors can show you exactly where your home’s energy goes.

When purchasing a home energy monitor, the first step is to determine which type is best for your home’s needs. Occupants of energy-efficient homes might prefer tracking only one or two appliances, while those looking to implement energy improvements across the entire home may want a more comprehensive model.

A smart plug is the easiest way to measure the energy use of an individual outlet. These are best suited to tracking a few energy-hog appliances rather than everything that runs on electricity. To use a smart plug, simply plug it into a wall socket and then plug an appliance into it. By linking the smart plug to your home’s Wi-Fi, you can see how much energy the appliance uses.

However, smart plug monitors have limitations. They’re not intended for larger appliances, such as laundry machines. Instead, they’re better suited to smaller implements like blenders, hair dryers, and electric weather stations.

For a detailed account of energy use throughout the home, consider a whole-house power monitor. These monitors have sensors that connect to your electrical panel or meter. They track the performance and power consumption of each of your home’s appliances based on their connections to individual circuits.

The sensors gather information, and the electricity usage monitor analyzes the data and transmits insights or notifications to a phone or computer dashboard. When linked to Wi-Fi, home energy monitors provide details on energy use and cost in real time.

Choosing the best home energy monitor depends on your needs and preferences. By finding one with the right programs and features, you can enjoy the benefits of an energy-saving home upgrade that pays for itself.

Our recommendations for home energy monitors include models that can monitor an entire house, specific circuits, or a single outlet. That versatility is helpful for homeowners who need total electrical usage monitoring or who may already have an energy-efficient home and only want to monitor a few devices. For our list of top picks, we included products at a number of price points while prioritizing ease of use, accurate tracking, and the convenience of operation via app or voice-activated controls.

Most of our included options rely on Wi-Fi connectivity, but we also chose a monitor that uses an ethernet cable if you prefer a more steady connection. Several units can monitor solar generation and output, which might be helpful for some homeowners.

To choose which home energy monitor is right for you, you’ll want to consider how much and what type of information will be most valuable. Different monitors might include energy details on a home’s solar system or appliance-specific information only. Some may work via voice commands, have an easy-to-use app, or offer easy installation.

Home solar systems can lower an electric bill by using a solar inverter to transform energy from the sun into alternating current (AC) electricity. These devices track both the energy used and the energy generated and can identify times of peak solar power.

Solar home energy monitors connect to a home’s utility meter to discover and track patterns in energy input and output. Some devices show a side-by-side comparison of this data and send the owner notifications if they detect changes in the amount of energy consumed or produced.

Whole-home electricity monitoring devices plug into individual circuits on the electrical panel. Some of these systems offer circuit-specific details, but smarter systems learn the unique electrical signatures of each appliance and track them individually. Appliance-specific recognition pinpoints the energy use of appliances big and small, and some can even create alerts about details such as an open fridge door.

Appliance recognition allows energy monitors to make more specific recommendations to reduce energy. They can send notifications to unplug a blow dryer, adjust a programmable thermostat, or advise which appliances need to be upgraded to more energy-efficient models. Tracking the energy consumption of each appliance rather than all the appliances attached to a circuit can provide actionable information regarding reducing energy use.

Your electricity bill is a record of how much energy your home uses weeks after the usage occurs. Tracking how energy gets used in real time enables a home’s occupants to act in the moment to minimize energy waste. Energy monitors may show current tracking in kilowatt-hours and dollars, providing information as to how much energy a family is using and what it costs them.

Ongoing tracking and real-time notifications can uncover behaviors and patterns that contribute to energy overuse. This information helps you find sources of wasted electricity and correct them. A benefit of real-time cost tracking is locating “vampire” appliances that draw electricity in standby mode so they can be unplugged, replaced, or used more efficiently.

Even if you’re already taken steps to make your home a smart home, you can benefit from a home energy monitor. Whole-house smart-home energy monitors fit into the home’s electrical panel and connect wirelessly to other devices in the home. A Wi-Fi–enabled home monitor can communicate and interact with other smart-home devices.

Linking the energy monitor to a smart thermostat or smart plug provides detailed energy-use data and enables users to operate appliances without being near them. These models show up-to-the-second energy use in the home, identify patterns, calculate the costs of operation, and more.

Once the device is installed, home energy monitors negate the need to read meters or visit the electrical panel. Many systems connect home energy information to a smartphone to deliver instant updates about energy usage.

Many home energy monitors have a downloadable app with a dashboard that tracks usage, trends, and more from a phone or computer. In some cases, the app can review and initiate action items from remote locations. Many also allow users to set up notifications regarding critical use events, peak usage times, instances where energy is being wasted, and other analytics.

Some whole-home and smart-plug energy-tracking outlets are compatible with Google Assistant and Alexa. Syncing the monitor to these digital assistants gives users hands-free capabilities, which can be especially helpful for those with mobility issues or use in areas where an outlet is difficult to reach. Digital assistants can give quick updates, and users can employ voice commands to activate energy-saving tasks, such as turning off appliances.

Individualized programs can save energy in the home. Each home energy monitor has a program to manage technology and energy. Some examples of home energy monitor programming possibilities include the following:

Timers are also helpful features for minimizing energy waste. You can program them so outlets turn off after a specific amount of time to prevent vampire appliances from drawing energy.

Basic plug-in monitors measure the energy used by individual appliances plugged into a wall socket. To install these models, simply plug them into a wall outlet and plug the appliance into the monitor.

Installing a whole-home energy monitor either inside the electrical panel or near it on a wall is more complex. Typically, the monitor includes sensors that clip to individual circuits and a small unit that analyzes the information. The number of individual circuits to be monitored can influence the choice of which home energy monitor to purchase. Many of these models need to be installed by a licensed electrician. Once they install the hardware, you can connect it to your Wi-Fi and download the monitor’s app.

Selecting a home energy monitor requires a bit of research. Here are some of the commonly asked questions and answers about home energy monitors to help you get started.

A home energy monitor has sensors that clip to individual circuits in the electrical panel to measure the amount of energy used by that particular circuit. It transmits this information to a smartphone or computer so you can see how much energy is used at a given time.

Home energy monitors are relatively accurate. Quality energy monitors can estimate usage accurately within 1 percent.

Smart plugs draw about 1 watt in standby mode. Still, the energy they save from limiting power to plugged-in devices makes up for the energy they use, making them a great tool to combat climate change.

Naughton says using a device to monitor electricity usage is an effective way to save on energy. “They’re a great option for hectic households with fluctuating energy needs. They can be used to help your household become more sustainable and keep an eye on your kids’ screen time.”

Both are tools that track electricity usage, but they serve different purposes. Utility companies use smart meters as energy consumption meters to measure your home’s energy use to ensure accurate billing. Home energy monitors are used by homeowners to monitor electricity usage and make it more efficient.

Heating and cooling systems generally consume the most electricity in homes, followed by large appliances like water heaters and refrigerators.

According to Naughton, “Most home energy management systems range from $100 to $600. Costs will vary depending on how sophisticated the software is and your home’s unique layout. Home energy management systems that also monitor renewable energy production from solar panels also tend to be the more expensive option as well.”

The US Department of Energy says standby power accounts for 5 to 10 percent of household energy use and that unplugging your products is a good way to save electricity. They also recommend adjusting your home thermostat while you’re away and asleep to cut down on energy consumption.
