SENSE-24 · Home energy monitor
Save money by managing your electricity usage.
Clamp the mains and up to 22 circuits, pair your phone, and every load in the house has a name and a number.
How it works
Every load gets a name and a number.
Stop guessing which appliance is behind the bill. The Sense 24 measures each circuit in your panel directly, every second, and shows it on your phone.

Why Sense 24
More circuits, more history, no monthly fee.
Built to cover a whole panel, keep your data on your own network, and leave room to grow into load control.
24 inputs in all
22 branch circuits plus both mains — enough for most homes’ full panel, not just the big loads.
Readings every second
Power, current, and energy per circuit, with mains voltage and frequency. Catch the spike, not just the average.
Two weeks on the monitor
Up to two weeks of history stored on the device itself, and a year and more in the app.
Your data stays yours
A local REST API on your own network. Pull readings into your own dashboards and home automation.
Split-phase ready
Works on single-phase and 120/240 V split-phase service — the standard North American home panel.
No subscription
$199 once. No fees, no monthly plan standing between you and your own measurements.
