What Is a Smart Meter and How Can It Help You Save?
🇩🇪 Diesen Artikel auf Deutsch lesenQuick answer
A smart meter records your electricity use in short intervals and sends it to your utility automatically. Many utilities let you view hourly usage online, which helps you spot always-on loads, compare days and decide whether a time-of-use plan could save money.
Smart meters replaced manual meter reading in much of the US. Beyond billing, they give you a detailed view of your household's energy use.
What you can do with smart meter data
- Find your baseload: the lowest hourly use overnight shows always-on devices.
- Spot spikes: see what happens when the AC, dryer or EV charger runs.
- Evaluate time-of-use plans: check how much of your usage falls in peak hours.
- Get alerts: some utilities send high-usage alerts before your bill arrives.
How to access your data
- Log in to your utility account online or in the app.
- Look for “usage,” “energy insights” or “Green Button” data.
- Download hourly data or view daily charts.
