Home energy monitors (HEM) are Wi-Fi enabled devices that are installed in your home’s electrical panel. Many HEMs only provide the whole home view of your usage. Some HEM devices give you real time data on how energy is being used in your home. A device like the Sense Home Energy Monitor discovers the unique electrical signatures of the electrical devices in your home. The Sense monitor works by breaking those signatures down to tell you how much electricity each device is using. Other HEMs use sensors on each electrical circuit of your home.
However the monitor collects the data, HEMs then take this electrical usage information and turn it into charts, graphs, and overviews of your energy use and costs. They bring your energy use and home activity to life visually and deliver the information via mobile apps.
Home energy monitors have a lot of potential for helping homeowners save energy and money. Read on to find out about the three different benefits that using a HEM can provide.
By using a HEM, you can measure how much energy is being used by the devices or appliances you may have, such as space heaters, air conditioners, computers, or even toaster ovens. A study by the Natural Resources Defense Council found that the energy use from Always On devices across the U.S. accounts for 23% of power consumption in the average household, or about a quarter of any given electricity bill. A HEM can show you your ‘Always On’ – also known as your vampire load. You can even track it over time, so you can see the progress as you turn off forgotten lights and devices sitting on ‘standby’ that don’t really need to be.
The monitor can detect the biggest electricity users, and help you to save $100 a year, on average. Whether you are ready to take your home to net-zero, or are just trying to save a few bucks, a home energy monitor like Sense can help. Once you know which devices are consuming a lot of energy you can then decide what to do about it.
Most of the home energy monitors on the market have a mobile app for your smartphone. Notifications can help you see when your kids get home, if the refrigerator door is open, or whether your sump pump is on. Track spikes, trends, and more, right from your phone.
Simply buying and installing an energy monitor is not going to save you energy or money. However, these devices can highlight the way you use energy in your house and show you where you can save. Modifying your energy saving (or wasting) behavior is up to you.
Prices for HEMs vary from the low end of $70 to models that go for around $400. You’ll likely find that all the options will give you an understanding of how you are using power and what that will mean for your bill. There are a few different devices on the market, we encourage you to do more research and find a monitor that works for you. Be sure that the home energy monitor you choose is UL or ETL certified. There’s a great deal of potential in having a home energy monitor.
