To monitor home electricity use, start with your utility’s app or portal: it may show interval readings without extra hardware, though data can be delayed. For more detail, use an app with a compatible smart meter or a separate monitor connected at the electrical panel. Here are five routes to consider—the right one depends on your utility, location and equipment.
Five app-based ways to track electricity use
1. Emporia Energy
Emporia’s free mobile and web app shows energy use and costs, connected-device status and historical data. The readings depend on what you connect: a Vue panel monitor can show whole-home consumption and selected circuit-level breakdowns, while Vue Utility Connect reads from compatible smart meters in selected service areas. The smart-meter option is described by Emporia as providing near-real-time readings; that timing should not be assumed for other utility-connected apps. Emporia says its app has no subscription or in-app purchases, but monitoring hardware is separate. Its app page also reports “400,000+ Homes and counting”; that is a company-reported figure, not an independently audited user statistic or evidence of bill savings. Check Utility Connect’s compatibility details before relying on the smart-meter route. The Vue panel monitor supports up to 16 branch circuits per device, according to Emporia’s product support information.

2. Sense
The Sense app can connect to a Sense Home Energy Monitor installed in the electrical panel, or directly to a Sense-enabled smart meter if a participating utility supports access and has invited the customer. Sense says its system learns device patterns over time, so appliance identification should not be treated as instant or guaranteed for every device. The panel route requires compatible hardware and access to the electrical panel; the smart-meter route depends on utility participation. See Sense’s explanation of its app and monitoring options and its eligibility guidance.
3. Your electric utility’s app or portal
Check the app or website for the company that sends your electricity bill. Look for interval-usage graphs, usage by day or billing period, and whether the data is current or delayed. This route may work with an existing utility account and meter, but features and refresh rates vary by provider. It is not one universal app, and the available sources do not establish a complete directory of utility apps.
#1 Best Overall
- Various Monitoring Parameters: The power meter plug can monitor the power (W), energy (kWh), volts, amps, hertz, power factor, cost, minimum and maximum power (W), cumulative days and time of your appliances. By switching 7 display modes, you can easily know the various parameters while the appliance is working. The home energy monitor can also calculate and display how much power your appliance uses and how much electricity bill it cost in cumulative time
- Upgraded LCD Display: With large screen size 2.36 inch x 1.85 inch, clearer monitor backlit, our electrical usage monitor can display the data clearer and more visible no matter day or night. 180°full wide viewing angles is great for reading and recording the data in any angles. No need to stand on the front of the display and bend over to read the numbers
- Adjustable Backlight Time: Our upgraded watt meter has 5 options of backlight time. The default backlight time duration is 10 minutes(bL-0). If you want to change the backlight time, you can press and hold "UP" and "DOWN" button at the same time to enter backlight time setting, then press "UP" and "DOWN" to select the backlight time (bL-0 =10 minutes, bL-1=1 hour, bL-2=4 hours, bL-3=8 hours, bL-4=always on), finally press the "COST" to save the backlight time settings
- Overload protection: When the power of the appliance exceeds the overload power, the LCD will display “OVERLOAD” to warn the user. All the buttons will quit working and can only be workable when you lower or remove the load power. The default overload power is 3680W and is adjustable from 0 to 3680W. In general, you need to set the overload power to 1800W before using. Just press the "function" button for more than 3 seconds to enter the setting
- Data Memory Function: The wattage meter will record your power consumption data when you remove it from socket, or remove appliances from the electricity monitor. You can directly see the last data when you use it next time. This function can also automatically save the data when there is a sudden power failure
4. DTE Insight (DTE Energy customers)
DTE Insight is a regional option for DTE Energy customers, not a nationwide utility app. DTE lists usage reports, bill and energy tools, budgets, goals, tips and PowerScan. For real-time data, DTE says a customer needs an Energy Bridge paired with a qualifying AMI meter; without the bridge, usage information may be delayed. Availability and terms for the bridge or premium experience can change, so check DTE’s current pages before signing up: DTE usage tools, DTE Insight FAQ and DTE app and bridge features.
5. An app paired with an energy-monitoring smart plug
A compatible energy-monitoring plug can show the electricity use of the device plugged into it, such as a lamp or a small appliance. It measures that connected load, not the whole home. Check that the plug’s app and hardware support the features you need, and use a whole-home or utility-based option if you need to track total household consumption.

Choose based on the data you need
| Route | What it can show | What to check |
|---|---|---|
| Utility app or portal | Usage by interval or billing period, depending on the provider. | Whether your provider offers graphs, how often readings update and whether your meter is supported. |
| Smart-meter connection | Utility-supplied readings; Emporia describes its Utility Connect data as near-real-time. | Meter compatibility and service-area eligibility. Sense also requires utility support and an invitation for its smart-meter route. |
| Panel monitor | Whole-home use; some systems can also break out selected circuits. | Hardware cost, electrical-panel access and installation requirements. Do not assume every appliance will be identified. |
| Monitoring smart plug | Use by the one plug-in device connected to it. | Device compatibility and whether plug-level readings are enough for your goal. |
What to expect from electricity-monitoring apps
- “Real time” depends on the connection. A utility account may deliver delayed readings, while certain supported meters or add-on monitors can provide fresher data. Confirm the update interval for your specific setup.
- More detail may require hardware. A utility portal can be the easiest place to start. Circuit-level data typically requires a panel monitor; a smart plug covers only the device attached to it.
- App access and equipment are different costs. Emporia describes its app as free, with no subscriptions or in-app purchases, but compatible monitoring hardware costs extra. DTE’s bridge and premium terms may change.
- Tracking does not guarantee savings. The official material cited here does not establish a comparable typical bill-savings figure for these apps. Monitoring can help you see patterns, but the result depends on what you learn and change.
