How to choose a home energy monitor
A circuit monitor shows how much electricity the whole home and each monitored circuit use, so you can see when the air conditioner, water heater or EV charger is running and estimate what each one costs. A smart plug measures one plug-in device at a time.
Circuit monitors such as the Emporia Vue 3 install inside the main electrical panel: sensors clamp around the main feeds and the circuits you choose. Opening a panel exposes live parts, so have a licensed electrician install it unless you are qualified to work in one.
- How many circuits you want to see: Vue 3 kits come with 8 or 16 circuit sensors, or as the monitor alone.
- Your electrical service: confirm the monitor supports your panel before you buy.
- Wi-Fi at the panel: these monitors and plugs use 2.4 GHz Wi-Fi, so check the signal where they will be installed.
- Plug-in devices: a smart plug handles up to its rated current (10 A continuous for the Emporia Smart Plug).

What does a home energy monitor do?
It measures electricity use in real time, for the whole home and for each monitored circuit or plugged-in device, and shows it in an app. It helps you find which loads use the most energy; it does not reduce consumption by itself.
Do I need an electrician to install a circuit monitor?
A circuit monitor installs inside the main electrical panel, where there are live parts. Unless you are qualified to work in a panel, have a licensed electrician install it. A smart plug only needs an outlet.
Smart plug or circuit monitor?
A smart plug measures one plug-in device. A circuit monitor sees the whole home, including hardwired loads such as central air, water heaters and EV chargers, which no plug can measure.
Can a monitor help me size a backup battery?
Yes. A few weeks of real data show which circuits run on an ordinary day and how much energy they use. With that list, the battery backup calculator compares systems for the loads you want to keep on.
Which battery do I need?
Choose what you want to keep on and for how many days. The calculator balances your usage hour by hour against the battery, the sun or a generator, at today’s prices.
