Best Home Energy Monitors in 2021 [Top Reviews]

Best home energy monitors

Home energy monitors allow a home user to get a view of the inner energy workings of a home. The home energy monitor connects to the electricity meter of a home in order to measure how much energy a home is using as well as providing more information to the homeowner on how to better manage and make energy use more efficient.

The best home energy monitors come with various features from recognizing and measuring the home energy consumption of individual devices to generating personalized power consumption recommendations in order to achieve energy efficiency.

A home energy monitor will allow you a solution without requiring you to put more effort into remembering to turn the lights off and are relatively easy to attach to your circuit breaker.

Benefits of home energy monitors

Whenever you look at your energy meter or electricity bill you will get pretty light information such as how much electricity is used and how much that you are being charged but that is pretty much it and you do not get much info other than energy usage data.

If you would want to reduce your electricity usage in order to reduce your carbon footprint or even to save money, you would need to guess which devices are consuming the most energy. As such, a home energy monitor would be able to assist you in eliminating the guessing game.

The energy monitor is connected to the circuit breaker of your home and allows you to track energy consumption in much greater detail which allows you to cut energy consumption selectively.

The main benefit of a home energy monitor as mentioned just now is that it provides you info on usage which means you will be able to make informed decisions on how to reduce home energy usage which in turn helps you to save money! You will be able to track any overused air conditioning units, broken fans or heaters and if some of these devices can be fixed, will allow for more savings every month.

Besides, it will also be able to help avoid disasters since they also monitor energy usage for important equipment such as a basement sump pump in order to provide a safety net of sorts. This will ensure that your home does not get flooded resulting in expensive repairs.

What you should look for in a home energy monitor?

There are a few factors that you should consider when you want to get one to track electricity usage and we have compiled them into the list as below.

Household monitors vs Individual Appliance monitors

There are two main types of monitors which are household monitors and individual appliance monitors and it is important to distinguish between the two. Individual appliance monitors allow you to monitor the energy usage of a single appliance at any time and also provide more information about that particular device.

Meanwhile, household monitors are plugged into your energy meter and provide you with a complete and more general energy-use picture.

Appliance recognition

Different appliances in your home will have different ways of using electricity. Some home energy monitors will come with a recognition feature that is connected to your circuit breakers that will detect how appliances around your home are utilising electricity and will give you a sense of which appliance consumes the most amount of electricity.

Not every home energy monitor will have this feature though, and even the energy monitor that does, the technology doesn’t necessarily work perfectly. It will normally be easy for a home energy monitor to distinguish appliances between a TV or a refrigerator, however, appliances which use electricity in similar ways such as a toaster and a curling iron would be more tricky.

Real time cost tracking

Certain home energy monitors would allow you to track the energy usage of your devices in real-time. The benefits of real-time tracking allow you to watch as your energy usage either increases or decreases.

What this means is that you will be able to monitor and get a sense of the effects of turning certain devices off and on. As such, if conserving home energy is important to you, you should pay attention to whichever devices possess this feature

Mobile app

Most modern energy monitors would come with a mobile app that will be able to send notifications about your devices and provide tips for further savings as well as any abnormal energy usage in your home. As such, if you would like to get an immediate sense of energy usage in your home, you should lookout for a home energy monitor that comes with a mobile app.


Unless you have some basic knowledge of your circuit breaker in your home, we would recommend you install your home energy monitor by consulting your electrician. The home energy monitor you will be purchasing might mark itself as a DIY device but anything to do with your circuit breaker will definitely come with shock hazards.

Bringing an electrician will no doubt increase the total cost of the equipment but will bring definite savings once it is installed, additionally, you could treat it as a cost to prevent any further costs that might come with any accidents that might occur.

Solar energy monitor options

For those of you that are looking for solar monitoring energy monitors, there are some devices out there that allow you to monitor how much energy your solar panels are generating as well as measuring how much is used.

Now that you know what to look for in a home energy monitor, let’s jump right into our top picks for your home energy monitoring system.

Frequently Asked Questions (FAQ)

Q: How do I monitor the energy usage of my home?

In order to get specifics of how much electricity you are using, you only need one tool which is commonly called a home energy monitor. This device will be able to tell you how much kWh a device or any other appliance is using. This monitor can either be a simple plug load monitor that plugs into your outlet or more complex devices which connect to your circuit board.

Q: How accurate are energy monitors?

Some monitors are different in their accuracy that depends on what power they are measuring. If they are only measuring apparent power it will be less accurate at lower consumption levels at under 100 watts.
