Power Usage Monitors: Basics and Tips

Having a variety of good-quality options is one thing, but choosing the best home energy monitor for your household is something different. It’s essential to be wary of at least the basic characteristics that a device may offer. Besides, each appliance has its specs that determine its operation.

These and many other factors are vital for picking a product that will serve you well for long enough. Let’s take a better look at these and some other things to consider before purchasing a monitor.

What are the electricity usage monitors?

E-monitors are appliances designed to perform the functions of standard electricity meters, i.e. collecting data about household power usage. While the standard utilities provide you only with indexes, e-monitors have a range of useful functions that come in handy.

Such may include power usage monitoring, data analysis, cost and pricing estimation, or even remote power source control. A device to measure electricity usage indoors is a helpful way of managing your electricity consumption properly since it can assist in forecasting expenses, as well as prevent power leaks and overloads.

How do electricity monitors work?

Connected to your house’s power circuits, the appliance synchronizes with the current flow and reads data from it. Since most of the monitors are automated, it normally takes around 3 seconds for the data to reach the display (or app). Using different measurement units, the data may be showcased in Volts, Watts, Amps, etc.

While a regular power consumption monitor designates only the energy used, modern devices can often compare the current power usage to the preferred one. Also, they can calculate and estimate the approximate pricing for monthly power billing. This is usually backed up by overload notifications and alarms to prevent power leaks and blackouts.

What to consider when choosing an electricity usage monitor?

kill-a-watt electricity usage monitorThe abundance of product options designates the development of the market. Different manufacturers tend to design the ultimate monitor that will serve its purpose without being invasive. However, it’s not always the case since each household requires a specific device to run efficiently. Pay attention to the following when picking your monitor:


Good-quality meters don’t, of course, cost a little penny. Because efficient functions require efficient technology, the price of a meter can range from 150$ to 1000$. Here, you have to mind the specifics and decide what exactly you want from your monitor.

Normally, a 150$-200$ device can be a match for a small or medium-sized household where power consumption isn’t too grand. Other, more expensive models can have features that you won’t use at all, hence additional expenses. Don’t look for the cheapest one but consider paying extra to obtain a good product.

Brand and reviews

Again, there are quite a few reliable manufacturers with an array of products. I cannot speak for all of them, but Emporia, Poniie, and Eyedro have been seen in action. If you’re opting between some of them, try reading home energy monitor reviews to see what previous customers think of your yet-to-be appliance.

Size and quality

Long gone are the days when a meter was hefty and bulky. Modern devices don’t normally exceed the size of a smartphone. Though additional equipment may take up some space, the sensors should be minute and neat. Also, pay attention to the material. You want your meter to be made of sturdy polymers to prevent overloads.

Ease of use and connectivity

You don’t have to be an electrician to install a monitor. Normally, it takes less than half an hour to connect the device to your power circuits (with the power off, of course). Just follow the instruction booklet to have a complete understanding of the process.

Consumption measurement

To have a vast scope of functions, manufacturers enable their meter to display measurements in different units, like Volts, Watts, Amps, etc. This makes the appliance highly versatile as it monitors all the aspects of the power circulation. Make sure to be aware of the units since they provide you with power overload notifications to prevent blackouts.


Should you have more questions on how to measure electricity usage with a meter, take a look here.

How can I track my daily electricity usage?

Using a power usage monitor displays all your current and future electricity usage, calculating the gradual usage rate. By keeping the record of all the indexes manually or with an app, you can deduce your daily usage.

How do electricity monitors work?

They read your power circuit indexes and provide you with the voltage, wattage, and other parameters. If designated, the monitor analyzes your power usage and predicts monthly electricity consumption. Also, it can show you the exact billing expenses at this rate.

What uses the most electricity in the house?

Most of the time, the fridge is to blame. It has a very energy-consuming cooling mechanism that requires many cycles to maintain the temperature. Besides it, the power can be drained from the TV and even a phone charger. Use the meter to detect your power leaks accurately.

Though Electricity Runs the House, You Don’t Have to Run Out of Money

Having a monitor in your house is not a luxury but rather a necessity these days. Not only does it help you keep track of your energy consumption, but it also prevents emergencies and overloads. Pick a hi-tech monitor to maintain your expenses or choose a simple plug-in meter to find the power leak source. Whatever you choose, it will prove most useful in the long run.
