Track energy use in real time at the sub-second level.

Yes, really

How it works


Install the Sense monitor in your electric panel.


Download the app for iOS or Android.


Connect the monitor to Wi-Fi.


Start listening! Monitor your power use in real-time right away.


Over the next few weeks, Sense will start automatically identifying devices, reveal trends in your power use, and keep getting smarter!

Simple installation

Installing the Sense monitor doesn't require any rewiring, but should only be done by a licensed electrician. Just two clamp on sensors around your mains and a 240v breaker.

Track energy over time

Monitor energy throughout the month to make sure you stay on track.

Set device-level notifications

Enable alerts when the garage door opens or the sump pump turns on.

Identify sources of energy waste

Find energy hogs, identify your energy baseload, and how much it's costing you.

Keep tabs on your home

Check whether the oven is still on, or whether the drain pump is running.

Sense Listens

Every electrical device has a unique electronic signature — its own voice. The Sense home energy monitor listens to those voices through current sensors in your electric panel. It records them millions of times per second. Then advanced machine learning detection algorithms work to distinguish one appliance from another — to recognize each individual voice. Over time, more and more devices are discovered as the Sense community grows.
