Buying Guide

Also known as electricity monitors, energy monitors are small devices that allow you to keep on top of how much electricity your household is using.

Below you will find more about the benefits of installing an energy monitor and the features you should look for when purchasing one.

Features to consider when choosing a home energy monitor

There are many features to consider when buying a home energy monitor, but some of the most important to take into account include connectivity, compatibility, consumption measurement, and ease of installation. Other factors that you may want to look into before making a purchase include length of wires, warranty, and the monitoring platform you need to use with the appliance.

Connectivity

The main choices for connectivity are a wireless Wi-Fi connection and Bluetooth. Some models have both of these connection options, but they are not necessarily needed for showing you how much energy you have used.

The main reason to choose a Wi-Fi energy monitor is to send the data to an app on your phone or tablet to monitor historical usage and more.

Consumption measurement

Some models such as our editor’s choice, the Sense energy monitor, or the Neurio home energy monitor, measure consumption in both kWh and dollars and cents so you can see exactly how much your bill should be. However, other models only measure in kWh, so you have to work out how much your electricity bill will be by yourself.

Compatibility

When buying an energy monitor, you need to be sure it is compatible with the voltage of your home. Most models support various voltages, including 120/208/240V, whereas others are only suitable for split-phase households.

Ease of installation

The majority of energy monitors are straightforward to set up, and generally all you have to do is plug the device into a transmitter that sends relevant usage data to a control panel.

Some others require installation into the mains panel of your home, which means that you’ll need a licensed electrician to set up the device.

Monitoring platform

You can choose between energy monitors that come with support for iOS or Android apps, or go for a model that only has a web browser platform where you can monitor your consumption.

Power

Some models, such as the Eyedro EHWEM1, for example, require batteries, whereas others are mains powered. If you’re looking for extra portability, a battery-operated model may be a good choice.

Length of wires

This depends from one model to another, but many energy monitors come with all the wires needed to perform a quick installation. Make sure that the wires have a suitable length for you to be able to install the monitor where you need it, and that they’re not so long you’ll be tripping over them.

Warranty

Again, this differs from one model to another, but generally you can expect to get at least a one-year warranty for your energy monitor.

FAQ

Many of the energy monitors available on the market are very easy to install and do not require the help of an electrician. However, other models may require wire cutting or the manufacturer may have stated that a licensed electrician is required for installation. For instance, this is the case for Sense monitors.

Because energy monitors send details to the energy provider, many people are apprehensive about using them because they are worried about data protection. However, all data is sent securely, and you can usually find out exactly what happens to the personal information that is collected at the time you set up your device.

It is possible to see how much electricity your appliances use, but this is not a feature present on all of the energy monitors available on the market. Some models such as the Sense monitor track the overall energy consumption in your home as well as the individual use of any appliances you might have.

Our Verdict

After a thorough research, we concluded that the Sense monitor is the best all-around energy monitor on the market because it comes with all the features you may need to understand your electricity consumption while being affordable and easy to install. If you’re looking for a portable energy monitor, the Efergy Elite 4.0 is an excellent choice that also comes with the advantage of wireless connectivity. And finally, we found that the Eyedro EHWEM1 is a perfect choice for consumers who are looking for the best cloud-based energy monitor out there. No matter what kind of energy meter you decide to purchase in the end, make sure that you consider the way you intend to use it and its compatibility with your home electric wiring and voltage before parting with your money.
