1.) Use Smart Plugs for Individual Appliances

The most straightforward device to monitor home energy consumption is a smart plug or smart power strip.

Plug one into a power outlet and then plug your appliance into it. You can then get a reading on the amount of electricity the device consumes.

Smart plugs are ideal for use when you have just a few energy-hogging appliances that you want to monitor. Also, remember that these can only be used for small devices, such as a blender or hairdryer, and not for large appliances like washing machines or refrigerators.

This monitoring device can calculate how much electricity an appliance will use in a day, week, month, or year and how much it will cost you. 

It also checks the quality of your power line by monitoring voltage, power factor, and line frequency, so you know for sure whether your refrigerator is gobbling up power or something is wrong with the line.

2.) Use a Whole-Home Electricity Monitoring Tool

A whole-house power monitor can track the energy usage of all the appliances installed in your home. It has sensors you can connect to your home’s electrical panel or electricity meter.

The monitor can then track power consumption by all the appliances connected to an individual circuit. 

Whole-home energy monitors provide a holistic view of energy usage in your home. However, sometimes you may want to know how specific appliances are performing and if some devices are using more power than you want them to. 

Most energy monitoring systems support different household electricity voltages, such as 120V, 208V, or 240V. However, some units work only with split-phase households. Be sure you know which system is appropriate to install in your house. 

Whole-house energy monitors come with different functionalities. Read on to find out how the different models can provide you with as many energy usage details around your house as you want.

3.) Use Monitors With Appliance Recognition Features

Whole-home energy monitors connect to individual circuits on the electrical panel. Some monitors only provide cumulative data on power consumption by all the appliances plugged into a particular circuit. 

However, more powerful whole-home monitors have a built-in appliance recognition feature to track power consumption by every device plugged into the sockets in your home.

These smart-systems learn the unique electrical signature of each device and can track them individually.

You can give a unique name to every appliance on the app, so you know which television in the house is switched on or which PC is guzzling power through the night.

Knowing how much energy each appliance consumes rather than having a cumulative number for all the devices plugged into a circuit lets you adopt concrete and targeted measures to optimize energy usage.

Some of these monitors with the application recognition feature are so powerful that they can analyze data and detect consumption patterns to give recommendations.

For example, they may suggest switching off a device at a specific time during the day, adjusting a programmable thermostat, or upgrading a particular appliance to an energy-efficient model. You can also customize these monitors to alert you about details, such as when the refrigerator door is open.

So, powered-on but idle devices, such as computers and video recorders in sleep or standby mode, contribute to a quarter of your electricity bill

Smart whole-home energy monitors can track electricity consumption in real-time. You can use the data collected by the sensors to find out the sources of wasted electricity and identify vampire loads. 

5.) Use Energy Monitors That Connect to a Mobile App

The more information you have about your home energy consumption, the more informed you can be. These insights are potent triggers for you to initiate behavioral changes and adopt measures to help you become more energy-efficient. 

Today, most home energy monitors have downloadable apps that can provide instant updates on your home energy consumption. These apps are easy to navigate and present the numbers visually, so you can instantly gauge what’s happening with your home’s energy. 

In general, an app can store data and generate reports and insights to help you determine the right size of a solar PV system that you may want to install in the future.

In addition, using energy monitors connected to mobile apps helps reach energy-saving goals in the following ways:

  • They alert you about appliances that are consuming more power than usual.
  • They send you notifications about appliances so you can identify those that need to be unplugged or upgraded to a more energy-efficient model.
  • They help you monitor your progress if you program your target energy consumption goals into them. 
  • They send you recommendations on saving electricity. 
  • Some apps can review the data collected by the sensors and initiate actions, such as powering off an appliance from remote locations.
  • They make tracking your home’s energy usage easier by saving the time and effort you need to visit the electrical panel or read meters.

6.) Track Energy Usage Cost in Real-Time 

You may want to monitor your home energy consumption to keep tabs on your utility bills. Some home energy monitors let you track the cost of your power consumption in real-time.

The real-time cost tracking feature lets you watch how your home energy consumption and costs increase or decrease at specific times of the day or as you switch on or switch off a particular device.

7.) Monitor Solar Electricity Generation and Usage  

Suppose you have a solar power system installed in your house or are considering going solar. In that case, you can keep tabs on the electricity generated and usage with solar-ready home energy monitors. 

These energy monitors let you track the following parameters of your solar setup:

  • Energy generated by your solar panels 
  • Time of usage 
  • Pattern of usage

This data helps determine whether the solar panels are generating as much power as they should. 

These numbers also help you optimize your time-of-use rate plans. For instance, you can run specific devices on solar power during the day when buying electricity from the grid costs more.
