The Best Energy Monitoring System: Top 10 Picks

You should not wait until your electric bill arrives to determine your energy consumption. The bill only tells you how much energy you use over a given period and for the entire year, but it doesn’t show you how to reduce your usage.

A good energy monitoring system provides real-time data that can help you use less energy by providing more accurate data and usage trends. A home energy monitor can catch inefficiencies, sync with smart-home tools, and even calculate solar system energy production. In addition to monitoring energy use as it occurs, it breaks down the cost of energy into kilowatts, dollars, and cents. Learn exactly where your energy is going by using the best energy monitoring system.

Before You Buy a Home Energy Monitor

In order to choose the best home energy monitor, it is important to determine which type is right for the user. Energy-efficient homeowners may only want to know about a few appliances, while those who want to improve their home’s energy efficiency across the board may prefer a more comprehensive approach.

Outlet Monitoring

A smart plug outlet is the easiest way to measure the energy use of an individual outlet. These outlets are best suited for tracking a few “energy hog” appliances rather than everything powered in the home. These smart outlets connect to the home’s Wi-Fi, and the appliance plugs into the smart outlet. By connecting the smart plug to the home’s Wi-Fi, the device uses how much energy.

It is important to keep in mind, however, that smart plug monitors do have limitations. They can’t be used to monitor larger appliances like laundry machines, but they can monitor smaller appliances like hair straighteners and blenders, for example.

Whole-House Power Monitors

A whole-house power monitor, which has sensors that connect to the electrical panel or meter of your home, can help you track your home’s energy use in detail. Based on how each appliance is connected to a circuit, the energy monitor tracks its performance and power consumption.

In a home energy monitor, sensors gather information, and a monitor analyzes it and transmits the information to a computer dashboard or smartphone.

What to Consider When Choosing the Best Energy Monitoring System

The best energy monitoring system for each household supplies the information that’s most valuable to the user. It may provide information about a home’s solar system, appliances, or energy usage, enable voice commands, have a simple app, or have an easy installation process. Here are some factors to consider when selecting the best home energy monitor.

Solar Monitoring

A solar inverter converts the sun’s energy into alternating current (AC) electricity. These devices track and identify both the energy used and the electricity generated.

A solar home energy monitor uses a home’s utility meter to monitor energy input and output. Some devices compare this data side-by-side and alert the owner if energy consumption or production changes.

Appliance Recognition

A whole-home energy monitoring system connects to a single circuit on an electric panel. Some of these systems provide circuit-specific information, while smarter systems learn the unique electrical signatures of each appliance and track them individually. With appliance-specific recognition, you can track how much energy appliances use, and even get alerts about a fridge door open.

A smart energy monitor can make specific recommendations to reduce energy use based on appliance recognition. Notifications can be sent to unplug a blow dryer, adjust a programmable thermostat, or recommend which appliances need to be upgraded to be more energy-efficient. Instead of tracking all appliances attached to a circuit, it is possible to reduce energy use by tracking the energy consumption of each appliance.

Real-Time Cost Tracking

An electricity bill provides information about how much energy a home uses weeks after it has occurred. By tracking its use in real-time, occupants can act in the moment to reduce waste. In addition to providing information on how much energy a family uses and how much it costs, energy monitors may show current tracking in kilowatt-hours and dollars.

It is possible to uncover behavior and patterns that contribute to energy overuse by tracking in real time and receiving in-the-moment notifications. This information can help identify wasteful electricity sources and correct them. Using real-time cost tracking, you can identify vampire appliances that use electricity while sitting idle and energy hogs, so they can be unplugged, replaced, or used more efficiently.

Smart-Home Compatibility

The smart-home energy monitor connects wirelessly to other devices in the home. The monitor can also communicate and interconnect with other devices that are part of the smart-home ecosystem.

Smart thermostats and smart plugins enable users to control appliances with the press of a button and give a more detailed description of data than other monitors. In addition to showing energy use on a real-time basis, these models identify patterns and calculate operating costs for your home.

Mobile Apps and Notifications

It is no longer necessary to read meters or visit an electrical panel once a home energy monitor is installed. Many systems connect home energy data to a smartphone, providing instant updates about energy usage. The apps are intuitive and visual, so it is easy to understand what’s happening with a home’s energy and identify areas for improvement.

Home energy monitors often come with an app with a dashboard that lets you see usage, trends, and more. You can set up alerts within the app to keep you informed about critical usage events, peak use times, energy waste, and other analytics. In some cases, the app can review and initiate action items remotely.

Voice Control

It is possible to use Alexa and Google Assistant with some whole-home and smart-plug energy tracking outlets. In addition to giving users hands-free capabilities, synchronizing the monitor to these digital assistants also enables easy access to outlets that are difficult to reach for the elderly, those with mobility issues, or those living in remote areas.

Smart systems enable users to use voice commands to initiate energy-saving actions, such as turning off appliances with a verbal request, rather than logging into an app dashboard.

Programs and Timers

The following examples of home energy monitor programming possibilities will show you how to save energy in the home. Each home energy monitor has a program to manage technology and energy.

  • A smart system can be programmed so that the house will automatically heat up, the lights will come on, and the coffee maker will start when an alarm sounds.
  • It is possible to program appliances to turn off or switch to energy-saving mode when the user leaves 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. It is possible for the user to set alerts to remind him or her to turn off specific appliances.

A timer prevents vampire appliances from drawing energy and minimizes energy waste. Users can set it to turn off outlets after a specified period of time.

Installation

An energy monitor for individual appliances plugs into a wall socket. Simply plug it into the electric socket and plug in the appliance.

There is more complexity involved with installing a whole-home energy monitor inside or on a wall. Monitors typically include sensors that clip onto individual circuits and a small unit that analyzes the data. A home energy monitor’s choice can be influenced by the number of individual circuits to be monitored.

The device should be up and running within an hour of being installed. If you are unsure about how to install it, you might want to hire a professional. Once the hardware is installed, you can connect the device to your home’s Wi-Fi.
